HVAC Frequently Asked Questions

Have questions about the 2026 refrigerant phase-out, sudden AC breakdowns, or federal tax credits? Get straight answers from Fayette County’s premier Carrier® Factory Authorized climate experts.

Should I repair or replace my 15-year-old AC unit in Lexington?

If your AC is over 10–15 years old, it likely uses outdated R-22 or older R-410A refrigerant, making major repairs incredibly expensive due to parts scarcity. With the 2026 industry shift to high-efficiency SEER2 and R-454B systems, replacing an aging unit is often the smartest financial decision to lower your summer utility bills and prevent catastrophic mid-season breakdowns.

Why is my AC running constantly but my house is still hot?

This is a common issue during intense Kentucky summer heatwaves. It is typically caused by a frozen evaporator coil, a severely clogged air filter, a failing capacitor, or a low refrigerant charge indicating a leak. Turn your thermostat off immediately to prevent permanent compressor damage, and call our 24/7 dispatch line for rapid diagnostics.

Do heat pumps work well for cooling during Kentucky summers?

Absolutely. Modern inverter heat pumps are essentially advanced air conditioners that can reverse their cycle to heat your home in the winter. During a humid Lexington summer, high-efficiency heat pumps provide exceptional cooling and superior indoor humidity control compared to older, single-stage traditional AC units.

How much can I save on a new HVAC system with IRA tax credits?

Under the Inflation Reduction Act (IRA), Lexington homeowners can claim up to $2,000 in federal tax credits for installing qualifying high-efficiency heat pumps and hybrid systems. Quantum Comfort will help you navigate these 2026 rebates and match you with the most efficient Carrier system for your home's specific footprint.

How often does my HVAC system need professional maintenance?

We highly recommend professional maintenance twice a year—an AC tune-up in the spring and a furnace safety inspection in the fall. Regular maintenance calibrates your system for peak efficiency, prevents costly emergency breakdowns, and keeps your manufacturer warranty valid.
