AAA Heating and Cooling: Expert HVAC Services Serving Longmont 80501

A frozen evaporator coil is often caused by restricted airflow from a dirty filter, low refrigerant, or a failing blower motor. Our technicians first diagnose the root cause, then perform the necessary repair—whether it's a refrigerant charge, coil cleaning, or motor replacement—to restore proper operation and prevent future freeze-ups.

Duct leaks force your furnace to work much harder, wasting heated air into your attic or crawl spaces and significantly raising your energy costs. We perform a thorough inspection to locate leaks and use professional-grade mastic sealant or metal tape to seal them properly, improving your system's efficiency and comfort throughout your home.

Before our cold snaps hit, we recommend a fall tune-up. This includes checking heat exchanger integrity for safety, testing ignition and thermostat operation, cleaning burners and the blower assembly, and inspecting the flue. This proactive service helps prevent mid-winter breakdowns and ensures your system runs safely and efficiently.
