Air Conditioner Repair in Commerce City

In Adams City and Adams Heights, the mid-century single-story homes were commonly built without central air. Systems added later often have small ducts, a single return and long refrigerant line sets. Those setups are prone to coil freezing when the filter is dirty and to warm air when the line set or coil leaks.

Line sets in these homes were often run along exterior walls or through crawl spaces when the AC was added. Kinked or poorly insulated lines raise suction temperatures and cut capacity, so we inspect the full run, not just the outdoor unit.

Commerce City is home to the Suncor refinery, the largest in the Rocky Mountain region, and many homeowners here want better indoor filtration. Upgrading to a higher-efficiency filter can help, but a filter that is too restrictive for your ductwork will cut airflow, reduce cooling and can freeze the coil. We check static pressure before recommending a filter upgrade.

We confirm the symptom and check the thermostat and filter, then test the capacitor, contactor, fan motor and compressor electrically. We measure refrigerant pressures and calculate superheat or subcooling instead of adding refrigerant by feel. If there is a leak, we tell you where it is and what fixing it involves.

Hail is common on the Front Range, and a bad storm can bend condenser fins enough to cut airflow. We check the coil on every visit. The diagnostic is free with the repair, every job is quoted at a flat price before we start, and there is no overtime charge.

Repair makes sense for most electrical and fan failures. A failed compressor or a leaking coil on a system past about 15 years usually points to replacement, and R-22 systems are costly to recharge because that refrigerant is no longer made. A heat pump is worth considering if you replace, since one outdoor unit can cool in summer and carry much of the heating load in winter, with your gas furnace as backup on the coldest nights. Before quoting any replacement, we check whether the existing ducts and electrical service can support it.

Commerce City's Building Safety Division issues building permits; call to confirm the requirements for your AC replacement. Electric service is from United Power or Xcel Energy depending on your address, and efficiency rebates are tied to your provider.
