Heating Integrity Audit.
Lexington winters can be brutal, with temperatures plummeting fast. Your heating system isn't just about comfort—it's about building safety and pipe protection. At **Hvac Pros Lexington**, we treat heating repair with the same clinical engineering intensity as high-end cooling. **Caleb Phillips** mandates a "No-Ghost-Fix" policy: we prove the failure with data before we prescribe a solution.
Combustion Analysis & Carbon Safety.
Gas furnaces involve high-intensity combustion. A cracked heat exchanger can allow carbon monoxide (CO) to infiltrate your home's airflow—a silent and deadly threat. Most HVAC techs perform a simple visual check; our team uses **Forensic Combustion Analysis** to measure oxygen (O2), CO, and CO2 levels in the flue gas. If those ratios are off, the heat exchanger is compromised.
Heat Pump Logic in Kentucky.
Many Lexington homes use heat pumps with auxiliary electric heat strips. These systems are notoriously complex, requiring perfect calibration of the reversing valve and defrost logic. If your system is "stuck" in defrost mode, it's wasting thousands in electrical resistance. We calibrate your outdoor temperature sensors and refrigerant pressure curves to ensure your heat pump operates at peak **COP (Coefficient of Performance).**
Electrical Sequence of Operation.
Modern furnaces use integrated circuit boards to manage the sequence of operation: inducer motor start, pressure switch verification, igniter glow, gas valve opening, and flame rectification. A failure at any step stops the heat. We don't just "reset" the board; we find the underlying voltage drop or mechanical resistance that caused the timeout. This prevented catastrophic board burnout and saves you hundreds in unnecessary part replacements.
24/7 Emergency Heating Response.
When the temperature is 10°F, you can't wait until Monday. Our technical dispatch is on-call 24/7 for the Lexington area. We carry a comprehensive inventory of hot surface igniters, flame sensors, and blower motors to ensure we can restore your home's thermal load on the first visit.
Heating Engineering FAQ
Why is my furnace blowing cold air?
This usually indicates a sequence failure. The blower is running, but the flame has been extinguished or failed to ignite due to a dirty flame sensor, a faulty igniter, or a tripped limit switch indicating an overheat condition.
How often should I have a combustion audit?
Caleb Phillips recommends an annual audit every fall. Carbon monoxide transparency is non-negotiable for system safety.
