Largo’s Furnace Maintenance Professionals

Your furnace needs two kinds of care to stay in top condition. Basic homeowner upkeep includes keeping air vents clear and regularly changing your furnace’s filter. A professional tune-up should also be completed in the fall to prepare your heating system for winter.

A professional furnace tune-up includes:

Lubricating moving parts
Testing electrical connections
Cleaning internal components
Testing for carbon monoxide
Calibrating your thermostat

Call us at (727) 594-7593 to schedule your fall furnace tune-up.

Why Annual Furnace Maintenance Matters

Annual service allows us to identify developing problems before they cause a system breakdown. For example, if the blower fan belt is wearing out, we may recommend replacing it before it malfunctions. Addressing these issues early reduces the risk of an unexpected furnace outage during winter.

Manufacturer Warranty Coverage

Annual furnace service is often required to maintain your system’s warranty coverage. HVAC manufacturers commonly require documented yearly maintenance and may deny future warranty repair claims when service is missed. This could leave you paying out of pocket.

Furnace Life Span & Replacement Planning

A tune-up can provide insight into how much longer your heating system is likely to last. Furnaces that burn natural gas, heating oil, or propane have a life span of around 15 to 20 years. Electric furnaces can last between 20 and 30 years. Like oil changes for a car, regular tune-ups help your heating system reach its expected life span.

After completing the annual checks, we can explain when an upgrade will likely become necessary. This gives you time to prepare instead of being caught by surprise.

Heating Maintenance Program Benefits

Our heating maintenance program includes priority service and repair discounts. Regular care also supports extended system life and lower energy bills while giving you a clearer picture of your furnace’s condition and future replacement needs.

Carbon Monoxide Safety for Fuel-Burning Furnaces

Furnaces and other appliances that burn fuel can produce carbon monoxide when ventilation is inadequate or equipment is improperly installed, maintained, or operated. Carbon monoxide poisoning often causes flu-like symptoms.

Warning signs include:

Headache, dizziness, and weakness
Upset stomach and vomiting
Chest pain and confusion

The EPA advises installing carbon monoxide alarms on every level of your home’s livable space. Place alarms at least 15 feet from furnaces and other combustion appliances, and test them once a month.

Annual Furnace Inspection Recommendations

The EPA recommends annual professional inspection, cleaning, and tune-up of central heating systems, including furnaces, flues, and chimneys. The Consumer Product Safety Commission also recommends yearly inspections by a professional of appliances that burn fuel to detect carbon monoxide leaks.

An annual furnace inspection addresses safety and system condition separately from manufacturer warranty requirements. For a combustion furnace, professional cleaning, ventilation checks, and carbon monoxide testing are important parts of responsible maintenance.
