Air Conditioner Repair in Longmont

We check the thermostat and power first, then test the capacitor and contactor and measure refrigerant pressures, superheat, subcooling and indoor airflow. We compare the temperature drop across the coil with what the system should produce. If refrigerant is low, we find the leak before deciding what to do.

For heat pumps, we also check the reversing valve, defrost controls and sensors, and read the inverter fault history on variable-speed models. Pricing is flat-rate and given before work begins, with no overtime fees, and the diagnostic is free when you go ahead with the repair.

Because electricity here comes from city-owned Longmont Power & Communications rather than Xcel, residents' cooling rebates go through Efficiency Works. Its HVAC incentives focus on air-source heat pumps, ductless mini-splits and ground-source systems. There's no standalone central AC rebate, so if your old AC needs replacing, a heat pump may be the only option that qualifies.

Efficiency Works has required the home to be at least a year old, the work to be done by one of its listed service providers, and the application to be submitted within 45 days of purchase. Equipment has to meet minimum efficiency ratings. Rebate amounts and rules change, so confirm them before you sign anything. City residents, including those in Weld County, have also been eligible for Boulder County's Switch Together heat pump group-buy.

Any AC replacement also needs a permit from the City of Longmont's Building Services, which lists air conditioners among the appliances that require one.

Electrical parts, fan motors and drain problems are worth repairing on almost any system. If an older R-22 unit has a compressor failure or a leaking coil, we'll explain what a repair would involve compared with replacement, including the heat pump rebate path through LPC, so you can make an informed choice.
