Air Conditioner Repair in Louisville

The city's building codes require electric-ready construction for new builds and renovations, and the city encourages heat pumps, so many Marshall Fire rebuilds have one handling both cooling and some or all of the heating. The first few summers are when installation problems become noticeable: refrigerant charge that wasn't adjusted for the line-set length, a condensate drain without a trap, or a variable-speed system whose thermostat wasn't configured correctly.

These systems run year-round, so a small issue doesn't stay small. We read the inverter board's fault codes, check the reversing valve and sensors, and confirm charge using the manufacturer's method rather than guessing.

Wildfire smoke and the area's wind carry fine particles and debris that settle on condenser coils and clog indoor filters faster than normal. A dirty coil raises pressures and compressor temperature, and a loaded filter starves the indoor coil of airflow. Both get worse on the hottest, smokiest days, which is exactly when you need the AC most.

If you've upgraded to a high-MERV filter for smoke, it may be too restrictive for your return. We can measure the pressure drop and suggest a setup that protects your air quality without causing the coil to ice up.

We check power, controls, the capacitor and contactor, then measure refrigerant pressures, superheat and subcooling, airflow and supply-return temperature difference. We track down leaks instead of just recharging and leaving, and on older R-22 systems we'll tell you plainly whether a leak repair is worth it for the age of the equipment. You get a flat-rate price before work begins, with no overtime fees, and the diagnostic is free if you approve the repair.

Electrical parts, fan motors and drain problems are worth fixing on nearly any system. A failed compressor or leaking coil on an older R-22 unit usually points toward replacement. If you replace, the city requires a Furnace/AC/Water Heater/Heat Pump permit pulled by a licensed mechanical contractor, along with a final inspection. A heat pump that needs a new circuit also requires a separate electrical permit unless the contractor holds both licenses. Xcel Energy is the electric utility here and offers heat pump rebates, and Boulder County has run a Switch Together heat pump group-buy open to Louisville residents.
