Why is my AC freezing up? How to Fix

If you ever find a frozen evaporator coil ( inside unit )  or you notice the refrigerant line going to your condensing unit outside is iced up, you have a problem. Shut your AC off and read the tips below.
If your AC system is freezing up, it’s important to correct the issue to prevent potential damage to your compressor. Compressor replacement is one of the most costly repairs on a homeowner’s AC system.

What causes your AC to develop ice?

A majority of icing issues are related to airflow issues. If the volume of air across the evaporator is low or restricted, the refrigerant in the system absorbs less heat from the surrounding air. The temperature of the refrigerant in the system drops to below 32 degrees – the freezing point of water. The humidity ( moisture) in the air slowly starts to freeze on the surface of the evaporator coil & ice forms. As the ice starts to form, it causes further airflow restriction & accelerates the ice formation.

Iced evaporator coil

How to thaw ice from equipment

Regardless of why the ice formed, the first step is to fully clear before correcting the problem. This can sometimes can take hours, depending on the severity. It is important to clear all the ice.* We are assuming a bad blower motor is not the reason for icing

  1. Adjust the thermostat setting from cool setpoint to the “Off ” position
  2. Adjust the Fan setting from ” Auto ” to the “On” position. The indoor fan will remain on constantly in this position. Make sure to return to the previous setpoint when finished.

What this does is shut the AC cooling off but allows the air handler fan only to operate. This allows the warm indoor air to accelerate the melting of the ice. Be aware that if the coil is heavily iced, some water may drip off the face of the coil as it thaws out. This is normal but if excessive, you may want to use a couple of towels or a wet-dry vac to suck up to prevent flooring damage, etc.

** This Tip would not apply if the indoor fan motor has failed – Typically it is pretty obvious the blower motor is operating. You can hear the operation or may feel some airflow. If the motor is not operational, simply leave everything off and call for a repair.

Most common reasons for system icing

  • Dirty Filter
  • Dirty evaporator coil
  • Ductwork issues 
  • Bad blower motor
  • Defective expansion valve
  • Low Refrigerant

Dirty filter

A very dirty filter can restrict ( slow ) airflow enough to allow the evaporator to form ice. Again, once the ice starts to form, it exacerbates the situation. Often once the ice is clear, just changing the filter will remedy the situation. Check the cleanliness of the evaporator at this point. Most systems have a small 1″ door where the filter is located. Look up under ( from the filter side) the evaporator coil from this filter location to see if significant dirt is on the coil. If ductwork is in your way, a cell phone can be used to snap a picture of the coil to confirm. If the coil is very dirty it may need to be professionally cleaned to restore proper function.
* Be careful not to drop your cell in the ductwork.

Dirty Evaporator

 If you’re not frequently changing the air filter, dirt can bypass and get embedded on the evaporator coil itself. This is pretty common. A dirty evaporator coil causes airflow restriction and loss of heat transfer to the refrigerant in the system.
Depending on how your system is configured, it may be possible to clean the coil yourself. Coil cleaner can be purchase online or at a local home store. Make sure you buy the appropriate cleaner designed for evaporator coil cleaning, Using the wrong product can damage the fin surface of the coil. This cleaner along with a nylon type dish brush to scrap the heavy dirt off may be sufficient to correct the problem.
** Be extremely careful not to bend the fin surface of the evaporator. You need to brush in the direction of the fins to prevent bending & damage. It can be very costly to replace the entire coil if damaged.
Depending on how dirty the coil is, it may be required to have to coil professionally cleaned. This may involve removing the entire coil to chemically clean.

Dirty evaporator coil

Ductwork issues

Damaged supply or return ductwork, or sometimes just improperly sized, also can cause enough airflow restriction to cause ice formation. All HVAC systems are designed to move a rated specific amount of air.Homeowners often inadvertently damage ductwork crawling around in the attic. Cable guys are notorious for damaging ductwork and leaving.

Bad Blower motor

If the interior blower motor stops operating – there is no airflow. Your system will ice up immediately. Blower motors do fail, but often it is only a run capacitor ( depends on the type of motor) that is required for the motor to operate. This usually requires a professional to correct.

Defective Expansion Valve

There is a refrigerant metering device located in the air handler. A TXV style metering device can fail or gets weak & not meter the correct amount of refrigerant to the evaporator. This can cause a condition that causes an icing situation. Professional service would be required to determine & correct.

Low Refrigerant / Leak

Loss of refrigerant is a very common reason for system icing. The Freon or refrigerant in the system is a chemical that has a consistent pressure/temperature relationship. For example, R-410 refrigerant at 120 PSIG correlates to approximately 40-degree refrigerant temp. This would be OK but if the system loses refrigerant and the pressure drops to say 96 PSIG the refrigerant temperature is 29 degrees – below freezing point – Icing can occur.

While there are other reasons for ice to form, these are the most common culprits. Give us a call if we can help! 727-392-6111.

How a Ductless Mini Split System Can Improve Your Home

How a Ductless Mini Split System Can Improve Your Home

Save money and energy with a mini-split installation in your home. This advanced AC system is a convenient and cost-effective choice for homeowners.

When looking for an effective way to cool their homes, many homeowners prioritize energy efficiency, easy installation, and cost-effectiveness. At first glance, it might seem impractical to find an AC system that lets you enjoy all of these features. However, a ductless AC system offers each of these benefits and more.
AC mini-split systems are highly versatile units that can efficiently cool homes, apartment buildings, and commercial facilities. Thanks to their ductless design, mini-split systems are known to limit energy loss and keep your home comfortable while allowing you to save money. Millions of homeowners have already requested a mini-split installation in their homes to more effectively cool their living spaces, and you can discover the same benefits in your own home. Here’s everything you need to know about installing a mini-split AC system in the St. Petersburg & Largo Florida area.

How Does a Ductless AC System Work?

A ductless air conditioning system, also known as an AC mini-split system, is a versatile and efficient unit that gives you the freedom to regulate the temperature in individual rooms. It accomplishes this by using a separate fan and evaporator unit for each room it has to cool. This process is markedly different from a conventional central AC system, in which cold air is generated in a single area and is spread throughout the house through large ducts.

As the name implies, a ductless mini-split system doesn’t rely on full-sized air ducts in order to properly cool a home. Instead, it utilizes two main parts: an outdoor compressor or condenser and an indoor air-distributing unit. These separate features play a key role in allowing the AC system to individually cool each room in a home.

There are a number of other parts that work together to keep a mini-split system running properly. The conduit, for example, is where the power cable, suction tubing, and refrigerant tubing elements are found. In addition, a standard ductless system contains a drain to allow for proper condensation.

Thanks to the compact nature of these parts, it’s easy to install and move them at any time. The simple installation process is just one of the many benefits of an AC mini-split system that makes this unit the top choice of countless homeowners.

Benefits of an AC Mini Split System

Mini-split air conditioning units have the potential to change the way you cool your home for the better. Before you request a mini-split installation in your own living space, it’s worth considering the top benefits of these units. Here are some of the main ways in which mini-split systems can help you save money and energy while enjoying a cooler home.

Better Temperature Control

One of the main reasons why homeowners have ductless mini-split systems installed in their homes is because of the greater temperature control they offer. Instead of relying on a central unit to pump cool air throughout your home, you can use a mini-split system to regulate the temperature in each individual room in your house. This feature is particularly beneficial for large homes, where a conventional AC system may struggle to fully cool down a large space.

In addition, you can focus on making each more room more comfortable with help from a mini-split AC system. For example, if there’s a specific room in your house that heats up faster than others, you can offset the extra heat by making the temperature in that room lower than the other rooms. This is an easy and effective way to monitor the temperature in a single room without affecting the rest of your home.

Energy Efficiency

The setup of ductless AC systems also makes them one of the most energy-efficient units available. If there’s a room in your home that isn’t being used at all, you can shut off the air conditioning in that room while keeping the rest of your home cool. Likewise, rooms that need more cool air than others can be adjusted accordingly without forcing your AC unit to blast cold air throughout the entire house.

Choosing which rooms to cool isn’t just a matter of comfort or convenience. This benefit also helps you cut down on wasted energy, helping you save a significant amount of money in the long run.

Compact Size

For homeowners who have small apartments or houses, the size of their AC system is a legitimate concern to take into account. Fortunately, ductless AC units are compact in size, which allows for a simple mini split installation process. Additionally, you don’t need to worry about finding enough space to move your mini-split system, because these units are extremely easy to transfer anywhere at any time.

Cost-Effectiveness

Another major benefit of mini-split AC systems is cost-effectiveness. As we discussed before, mini-split units allow you to cool individual rooms in your home and adjust the temperature in any room according to your needs. This gives you the freedom to raise the AC in unusually hot rooms and turn it off completely in rooms that aren’t being used at all. As a result of this high flexibility, mini-split AC systems let you save money over time, making them some of the most cost-effective options out there.

Ductless AC systems are also cost-effective in terms of timing. When you first install your AC unit, you may not want to cool every room in your home right away. You can therefore start by cooling the necessary rooms in your house and adding a mini-split unit to additional rooms when the time comes. No matter how you decide to use your mini-split system, you’ll be making a significant difference in saving money and energy over time.

Customization

With most central air conditioning units, your options for customization are very limited. Mitsubishi mini-splits and Gree mini-splits, on the other hand, provide plenty of ways to make your ductless AC unit your own.

One of the best ways to customize your mini-split system is to choose where to install the unit in your home. You can choose to hang it on the ceiling to keep it out of the way of furniture and other objects, or you can opt to place it on a wall or floor if you feel that will look more aesthetically pleasing.

No matter where you opt to place your ductless AC system in your home, you won’t have to worry about it taking up too much room or interfering with the design of your living space. Many mini-split systems are designed with sleek jacket covers that help give the units a more attractive appearance. In addition, most units are no more than seven inches deep, meaning they won’t create an obstruction in your home.

If you do decide to change the placement of your mini split AC unit for any reason, you can do so without any hassle. This flexibility helps give homeowners peace of mind in knowing that they have the freedom to move their AC systems according to their wishes.

Minimal Noise

Conventional AC units are notorious for making an inordinate amount of noise, disrupting the peace of quiet that homeowners prefer to enjoy in their homes. Ductless units go the extra mile by making considerably less noise once installed in your living space. This is mainly because the fans in mini split AC systems tend to run at much lower speeds than their traditional counterparts. The result is a quiet and unobtrusive operation that your entire family can benefit from.

Easy Installation

The installation process for conventional AC units can be a hassle. Fortunately, mini-split systems are extremely easy to install. No matter where you plan to place your unit in your living space, you can enjoy a simple and unobtrusive mini split installation process. Don’t hesitate to request an installation as soon as possible to ensure that your specific needs are met.

Requesting a Mini-Split Installation in the St. Petersburg & Largo Florida Area

The benefits of an AC mini-split system are numerous. Whether you’re looking for an easy and reliable way to save money or aim to cool individual rooms in your house in a more effective way, a mini-split installation in the St. Petersburg & Largo Florida area can allow you to reach your goals. Remember to take all of these benefits into account as you try to find a mini-split AC system that fits your needs. No matter where you decide to place the unit in your home or how you plan to use it to cool your living space, there are endless things that a ductless AC system is capable of when it comes to keeping you and your loved ones comfortable.

HVAC Ductwork Replacement – Do You Need New Ductwork?

HVAC Ductwork Replacement – Do You Need New Ductwork?

While every home’s HVAC ductwork system requires unique considerations, ducts in Florida homes do present some particular challenges for contractors and homeowners.

The ductwork in most Florida homes built in the last 25 years, is located in the attic.

While many homeowners take pride in having the most energy-efficient cooling equipment, they will not enjoy the investment benefits if their ducts are leaking. The average house loses up to 30% of the air from ductwork due to leaks and holes in the ductwork.

Common Ductwork problems

Why consider having HVAC ductwork replaced? What’s in it for Florida homeowners?

Appropriately sized, installed, and maintained ductwork is especially applicable to Florida’s homes given the building boom that began in the 1980s. Houses built before the early 2000s have ductwork that met lower regulatory requirements. The r-4 insulation that was previously deemed adequate no longer meets today’s more stringent code standards. And as every contractor knows, building codes serve only as a minimum baseline for energy efficiency.

There are also technological advancements to consider. Today’s high-efficiency HVAC equipment is very different compared to the systems made decades ago. Because of this, home ductwork systems may not satisfy the requirements of today’s modern HVAC systems.

How do you know if HVAC ductwork needs to be replaced?

A  home’s ductwork may give various signals that indicate a replacement is necessary. Virtually every HVAC contractor hears homeowner’s complaints about that room that is always too hot or sneezing which seems to only occur in certain sections of the house. Other customer complaints that may indicate a ductwork problem include:

  • Musty smell
  • Excessive duct
  • Mold/Mildew around vents
  • Water stains visible on the ceiling
  • Condensation on supply vents
  • Frequent equipment cycling
  • Hot or Cold spots
  • Visible ductwork damage
  • High heating/cooling bills
  • Poor airflow

How much does it cost to replace AC’s ductwork system?

The replacement cost of ductwork varies quite a bit between properties due to the type of existing ductwork, accessibility, and location of supply and return duct locations, even the type of ceiling material, whether it’s drywall, lath, and plaster or drop ceilings in commercial applications.

In general, the cost ranges from approximately $350 to $550 per duct run. Air Zero offers free duct replacement estimates to determine what is required.

Can I replace AC ductwork myself?

We have certainly seen many DIY duct jobs. Usually, this is less than ideal. Appropriate ductwork sizing and installation are critical for the proper performance of the equipment and to achieve the comfort level of the conditioned space desired. The 18 seer unit you just purchased tied into undersized ductwork is now a 12 seer unit, reducing the efficiency and potentially the lifespan of the equipment.

Undersized/poorly installed ductwork reduces the cooling capacity, uses more energy, and affects your house’s humidity level.

 Professionally Installed Ductwork Benefits

  • Correct sizing for existing equipment.
  • All manufacturers of air conditioning equipment specify recommended airflow requirements to achieve the rated efficiency.
  • Proper duct sizing also allows even distribution of air throughout the house
  • Correct duct installation helps the longevity of air conditioning equipment.
  • Reduces the frequency of equipment cycling
  • Proper static pressure reduces strain on the blower motor.
  • Sealed per code to minimize air loss.
  • Correct grill sizing, design, and placement of air grills to maximize airflow performance.
  • Installed & secured to maximize the lifespan of ductwork.
  • Extends the life of the air conditioning equipment.

When it comes to maintaining a healthy home, your HVAC system is a key factor. The largest (and most overlooked) component of that system is your home’s ductwork. Because it carries air to every part of your home, the condition of your ductwork can affect your home in ways you may not realize. Our HVAC System Health Check evaluates 12 key factors to identify hidden problems in your ductwork and help improve the quality, cost and comfort of your in-home environment.

  • RGF’s technology has been featured on Fox, ABC, CBS, and Popular Science Magazine

RGF does not claim to stop the spread of Coronavirus. Due to the recent development of the virus and does not have current data but is being tested. However, it has been shown to be effective with similar types of viruses. Here is an outtake from a recent article issued.

From the World Health Organization, “Coronaviruses (CoV) are a large family of viruses that cause illness ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS-CoV).” Further from WHO, “COVID-19 is an infectious disease caused by the most recently discovered coronavirus. This new virus was unknown before the outbreak began in Wuhan, China, in December 2019.”RGF® manufactures a range of air purification and air filtration products for residential, commercial, and healthcare applications. This bulletin aims to answer frequently asked questions for our distributors. Are test results available for RGF’s PHI-Cell® or REME HALO® on COVID-19? We currently do not have testing specifically on the Wuhan Coronavirus (COVID-19). We are evaluating testing options with partners in both the U.S. and China. As there are a limited number of facilities capable of testing for this virus, their focus is on prioritizing testing as it relates directly to the recent outbreaks. Is RGF’s PHI-Cell® and REME HALO® technology effective at reducing COVID-19? COVID-19 is a member of the enveloped RNA coronavirus (subgenus sarbecovirus, Orthocoronavirinae) subfamily. While RGF® does not have testing specifically on COVID-19, we have validated test results showing 99+% reductions on similar viruses. These viruses, like COVID-19, are also ‘enveloped’ or protein jacketed virus types. If we can reduce these virus types, an assumption could be made that we would also be effective at reducing the current coronavirus at hand. Important to note that we make no medical claims.

How does the Reme Halo work?

Reme Halo produces Ionized-Hydro-Peroxides that have been proven very effective at destroying harmful microbials in the air and on surfaces. Hydroperoxides are present in nature and have been around since we have been on earth. Over the last 25 years, RGF has more than 2 million products used successfully worldwide without any safety problems.

Air Zero installs & maintains Reme Halo products to protect your family & household. We are currently offering a special of $1159 to install one of these amazing products in your home.

Why Your Air Conditioner is Leaking Water Inside Your Home

Why Your Air Conditioner is Leaking Water Inside Your Home

Living in St. Petersburg means making it through the long and sweltering Gulf Coast summers every year. A well-maintained and powerful air conditioning system is one of our highest priorities as residents of South Florida. For that reason, it’s important to pay close attention to your home’s unit and provide the maintenance and repairs your system needs as soon as they become apparent.

One of the most common A/C problems is water leaking out of the unit. If you spot a leak from your A/C system inside your home, you will want to call a professional immediately for assistance. Leaking water can cause more damage the longer you wait to have it fixed.

At Air Zero, a Largo and St Pete AC company, we can help you find the source of the leak and get it repaired before it gets worse. Without proper repairs, you could set yourself up for a complete air conditioning replacement which could cost you thousands of dollars. In this guide to leaky HVAC systems, take a look at some of the most common causes of this problem and how to get it fixed fast.

Condensate Drain Line Is Clogged

One of the most common problems that can cause a leak in a home’s HVAC system is a clogged condensate drain line. A condensate line is installed in the home to allow the drain pan to properly reroute any condensation buildup to outside the home. When this becomes clogged with mildew and mold, you can experience a backup that will push water back out into your A/C system.

Clogged drain line

Malfunctioning Condensate Pump

If you have determined that your condensate drain line is clear, you will want to ensure that your pump is functioning as well. The condensate pump is used to pump water from the pan to the outside drain area. These are usually found in applications where gravity can not be used to drain the water. Depending on the type of pump, you may have to have a professional check your pump’s functions.

Dirty Air Filter

Dirty air filters are one of the easiest things that you can check for when you have a leak. A dirty or clogged air filter will cause the A/C system to work harder which can lead to coils freezing over and leaking. Scheduling routine maintenance appointments to change the A/C air filter will allow you to make sure that your air filter is always clean and that your system is not overworking itself.

Damaged Drain Pan

The purpose of a drain pan is to collect any condensation dripping out from the A/C system. This pan drains into the condensate line, where it is carried outside to drain properly. When a drain pan becomes rusted or damaged, you can experience leaks due to the pan not functioning as it should.

Your System Is Low On Refrigerant

Last but not least, your system may just be low on refrigerant. This is going to be the last check you want to do as it will require a professional to visit your home and inspect the system. Low refrigerant will force the system to work harder. This acts similarly to a dirty air filter, causing coils to freeze over and leak into places you do not want them to leak into.

What is Freon and Why is it Important?

What is Freon and Why is it Important?

When it comes to home and auto air conditioning, ensuring that cold air is there when you need it should be one of your top priorities. When dealing with an A/C system that is not performing as well as it should, you may have been told that you need to have your Freon levels checked. While most have a general idea of what this means, many do not know exactly what Freon is and why it is so important.

While there are many do-it-yourself kits available at most hardware stores, filling up on Freon is more complicated than you might think. That’s why professionals usually recommend that Freon fill-ups and air conditioning replacements are completed by a skilled professional.

Air Zero, a St Pete air conditioning company, can ensure that your air conditioning system is brought back to life while following all codes and laws revolving Freonyou’re your home’s AC runs on Freon, take a look at this quick guide from the experts at Air Zero to learn how it works, what it’s used for, and why new laws and regulations concerning Freon could mean that it’s time for an AC system upgrade.

What Is Freon?

Freon is a name trademarked by Dupont to describe a colorless gas that is used in refrigerators and air conditioning systems to produce cool air. It is also known as R-22, a term used to identify Chlorofluorocarbon (CFC). Since CFCs have been linked to global warming by causing ozone depletion, R-22 is in the process of being phased out—making it much harder and more expensive to refill older HVAC systems. Most newer systems are now running on R-134, which is a Tetrafluoroethane which comes from the family of HFC refrigerant.

How Does Freon Work?

The process of cooling your home, car, or refrigerator can be quite complicated as the Freon has to undergo a few processes to produce cooler air. All AC systems are equipped with coils and compressors to help make this possible. The compressor pushed down on the Freon, which greatly increases its temperature. The gas then moves into the coils, which cools it down into a liquid form. The cooled Freon can now absorb the heat from the outside air and push the cold air out to cool your home or appliances.

What is Freon Used For?

When most people think of Freon, they immediately think about home and auto air conditioning systems. However, Freon is used as a refrigerant in upright and chest freezers. Some dehumidifiers, food transport vehicles, and industrial food storage freezers use Freon as well.

What Is The Montreal Protocol?

In an effort to cut down on CFCs, the United States agreed to reduce its use of CFCs over an agreed-upon time. This agreement is known as the Montreal Protocol and was one of the biggest topics of climate change at that time. By January 1, 2020, the US has agreed to have cut down to 99.5% below its baseline use.

What does this mean for those who still require R-22? This does not mean that R-22 will not be available, it will just be much harder to find and will most likely be more expensive. Since Freon cannot be vented into the atmosphere, it has to be recovered and recycled. After 2020, if you are needing R-22, it will need to come from recycled products.

Do I Need to Upgrade My AC System in 2020?

If your AC system currently runs on Freon, don’t panic. Freon is not and will not be illegal to use after regulations to cut down on its usage take effect this year. However, as we mentioned in the last section, finding Freon will prove to be more difficult (and more expensive) as time passes.

Chances are, your AC system is in need of replacement if it’s still running on Freon. In 2010, AC manufacturers stopped producing Freon-reliant systems in favor of R410A, or Puron, a replacement that won’t harm the ozone layer. If your Freon-dependent AC system is over ten years old and showing signs of wearing out, there’s never been a better time than now to upgrade to a more environmentally-friendly system.

St. Petersburg Residents: Watch for These Signs of Air Conditioning System Decline

St. Petersburg Residents: Watch for These Signs of Air Conditioning System Decline

No matter how well you maintain your AC unit the eventual decline of your system is inevitable in a hot state like Florida. If you’re not ready for it, an AC breakdown could leave you and your family in a hot, uncomfortable home for days or even weeks. Fortunately, there are a number of red flags that can indicate your unit is on its last legs. If you’re able to recognize these signs early, you could prevent a total breakdown and ensure that your home is never without AC in the heat of the summer.

Want to monitor the state of your air conditioning? Then watch for these tell-tale signs of decline:

  • The airflow is weak – Take a minute to go feel your air vents. Is the flow coming out of them, strong? Or is it just barely blowing? Weak airflow could indicate a serious (and costly) issue in your unit. It could mean that your blower or fan is damaged and that a breakdown of the entire system is imminent. If you feel weaker-than-normal air flow, check your air filters first. If they’re clogged, that may be the culprit. If not, call a technician as soon as possible for a full evaluation.
  • The unit is noisy – AC units are designed to be quiet, so any time you notice a new noise or sound coming from your system, consider it a red flag. Rattling, shaking and banging noises typically mean a part has broken down or become loose, and it will likely need to be replaced. Get a professional to check out your unit as soon as possible if you begin hearing strange noises.
  • It takes longer to work – When it comes to issues with air conditioning, St. Petersburg FL residents stuck in the heat can most easily recognize this one. If your AC unit suddenly stops cooling your home as quickly as it used to, it usually means there’s a big problem. You could have a refrigerant leak, rusted or corroded pipes, or a broken condenser or fan. Regardless of the underlying issue, it typically means your unit is about ready to quit on you.
  • It needs repairs often – A small repair every once in a while is not a big deal; in fact, most large appliances require a repair at least every couple years. If your unit starts requiring a fix every month, or even every six months, it’s definitely time to consider a replacement. You’ll probably spend less on a new unit than you would on a year’s worth of repairs if it breaks down often.
  • Your energy bills are higher – In Florida, air conditioning bills are always a bit higher in the summer. If they go up in any other season or if they suddenly get even higher than usual in the summer months, it indicates that there is probably a problem within the AC unit. The system may simply be out of date and no longer as efficient as it once was, or it could be in need of repairs or replacement parts. It’s important to get the unit evaluated as soon as possible to prevent even more added costs.

To ensure proper, working air conditioning, St. Petersburg FL residents need to be diligent about regular maintenance. They should also be able to recognize potential red flags that indicate their units are aging or in need of replacement or repair. This will not only keep their home cool and their loved ones safe, but it will also ensure that energy bills and operating costs stay low.

When you’re having issues with your AC system or it’s time to install a replacement unit, it can be very tempting to do it yourself. After all, think of all the money it would save you! But while this idea is good in theory, the truth is, handling AC repair and installation work when you’re not trained to do so can end up causing major problems for both you and your AC unit. It can put your health at risk, it can jeopardize your AC system, and it can cost you much more in the end to fix a mistake you could have avoided from the start by calling in a professional.

Ultimately, it almost always best to hire a professional to handle emergency AC repairTampa residents who try the DIY approach to their repairs may:

  • Injure themselves – AC units aren’t simple machines. They have a number of moving parts, electrical circuits, chemicals, and coils in them, and they take a lot of training and experience to truly understand. If you’re not well-versed in AC systems or their repair, trying to make fixes on your own can be extremely dangerous. It could even lead to electrocution if you’re not careful.
  • Cause even more damage – Though you may think you’re saving money by attempting your own repairs, in the end, it could cost you much more than you bargained for. Not only do you have to pay for all the parts that need replacing, if you make a mistake or break something else in the process, but you also have to pay to fix those as well! You could also void any warranties from the manufacturer or those who last serviced your machine.
  • Make incorrect repairs – If you’re not trained in AC repair, it’s easy to make silly mistakes when working on your unit. Ultimately, these won’t just affect your unit’s ability to function, they could also cause problems for your entire home, like short-circuiting your electrical system.

When it comes to emergency AC repair, Tampa homeowners should always call in a professional to handle the job. It will keep them safe, keep their unit in top condition and prevent additional damage from occurring.

Ac Installation Tampa: 7 Signs You Need a New AC System

Ac Installation Tampa: 7 Signs You Need a New AC System

A highly efficient, optimum-functioning AC system is crucial in Florida. We use them year-round to cool our homes, stave off humidity, and ensure that our air is clean, clear, and healthy to breathe. Unfortunately, this frequent use (and sometimes overuse) often causes units to wear out faster than normal, and that wear and tear forces homeowners to purchase a new system, cough up a few thousand dollars, and hire a professional to handle the AC installation. Tampa residents know this can add up fast.

Luckily, just because an AC system is down or not working properly doesn’t always mean it needs an outright replacement. In fact, most of the time, you won’t need a full replacement unless your AC system has any of the following problems:

  1. It’s more than 10 years old. Once your AC unit hits the 10-year mark, it’s probably time to start shopping for newer models. Older units simply can’t cool as efficiently as they once did, and your energy bills (and home temperature) will quickly start to reflect that. Consider hiring a professional to recommend a new unit and handle the AC installation. Tampa residents will see amazing improvements after installing a new unit.
  2. It needs repairs often. If your AC system has started to need repairs often – like once every few months – then something is seriously wrong. It’s either too old to do its job, or its parts are just too worn out to function properly. Either way, it’s likely time to get a new one. Call in a professional to get a full evaluation ASAP.
  3. It’s not cooling as efficiently as it should. Have you noticed your home just isn’t as cool as it used to be? Is it taking your AC unit more time and effort to cool down your space? If so, these can all indicate that a system is on its last legs. Have an AC professional come in and do a temperature test where they will check the incoming air versus the outgoing air. If the difference isn’t at least 15 degrees, it’s time to replace your unit.
  4. It still uses R22. Though R22 used to be the norm in most AC systems, it is now being phased out by the government in an effort to conserve energy and reduce emissions. Because of this, R22 prices have gone up exponentially. If your AC unit still uses R22 as its refrigerant, you’ll want to switch to a new model that uses R410A instead. This will end up being much more cost-effective (and efficient) over time.
  5. Your energy bills are higher than usual. If your energy bills are suddenly skyrocketing, but you aren’t doing anything differently, then there’s a chance that your AC unit is the culprit. You’ll want to call in a professional to evaluate the unit and see if you need a replacement. With a new, more updated AC installation, Tampa residents can enjoy not only lower energy bills but a cooler home as well.
  6. It’s emitting weird noises or smells. If you hear squealing, squeaking, grinding or other noise coming from your AC unit, that’s usually a sign that something is malfunctioning. Additionally, off-putting smells can signal a problem too. It may mean your wiring has burned out, there’s mold in your unit or there’s a leak of some sort. No matter what the case, it needs to be evaluated immediately.
  7. It has poor airflow. Check your AC vents and feel the airflow that comes out. Is it still strong? If not, it could mean there’s something wrong with your compressor or there’s a blockage in your vents. Ultimately, both of these will lead to inefficient cooling power, and they could damage your unit in the long run. It’s best to have it looked at as soon as possible to prevent further costs.
