New AC System Installation

For properties undergoing new construction or those looking to add central air conditioning where none existed, our new AC system installation services provide a complete cooling solution. We consider many factors beyond just square footage, including your home's insulation, window efficiency, sun exposure, and your specific comfort preferences to determine the ideal system for your space.

Our installation process involves:

  • Detailed load calculation 

We perform a precise analysis to determine the appropriate size of AC unit for your property.

We guide you through the various air conditioning options available, from traditional central air conditioners to ductless mini-split systems. We explain the features and benefits of each type, helping you select a system that aligns with your energy efficiency goals and budget.

AC System Replacement

When your current air conditioning unit is aging, frequently breaking down, or simply failing to provide adequate cooling, an AC replacement can be a wise investment. Replacing an older, inefficient system with a newer model often results in noticeable improvements in comfort and energy savings.

We begin by assessing your existing AC unit, evaluating its age, efficiency rating, and repair history. This helps us determine if a repair is still a practical solution or if a new AC replacement offers more long-term value.

    FAQs 

    How long does AC installation typically take in Largo homes?

    Most residential AC installations require 6-8 hours for straightforward replacements using existing ductwork and electrical connections. Installations involving ductwork modifications, electrical upgrades, or complex system configurations may require additional time. We provide accurate time estimates during your consultation based on your specific installation requirements. Weather conditions, permit requirements, and equipment availability can also influence installation timelines.

    What factors determine AC system sizing for Florida homes?

    Proper AC sizing depends on multiple factors including square footage, ceiling height, insulation quality, window orientation, and occupancy patterns. Largo's climate requires careful consideration of humidity control capacity alongside cooling requirements. We perform detailed load calculations that account for your home's specific characteristics and local weather patterns. Oversized systems cycle frequently and provide poor humidity control, while undersized units struggle to maintain comfort during peak demand periods.

    Do you handle permits and inspections for AC installations?

    We manage all necessary permits and coordinate required inspections for AC installations in Largo and Pinellas County. Our familiarity with local building codes and permitting processes ensures compliant installations without delays. Permit costs are typically included in our installation quotes, and we handle all interactions with local authorities. Final inspections verify proper installation and code compliance before project completion.

    What maintenance is required for newly installed AC systems?

    New AC systems require regular filter changes, typically every 1-3 months depending on filter type and usage conditions. Annual professional maintenance includes refrigerant level checks, electrical connection inspection, and component cleaning. We recommend bi-annual service visits during spring and fall to prepare systems for peak usage seasons. Proper maintenance maintains warranty coverage, ensures efficient operation, and extends system lifespan significantly.

    How do financing options work for AC replacement projects?

    We offer various financing plans to make AC replacement affordable for homeowners. Options include low-interest loans, deferred payment plans, and extended payment terms. Credit approval processes are typically straightforward, and we work with multiple lending partners to find suitable arrangements. Many financing options require no down payment and offer competitive interest rates. We explain all terms clearly and help you select the best option for your budget and circumstances.
