HVAC Services Billerica MA | Call Big Sky Air Balance

First, turn your system off to prevent further damage. Frozen pipes or coils are often a sign of airflow issues or low refrigerant. Our Big Sky Air Balance technicians can quickly diagnose the root cause—such as a dirty filter, blocked vents, or a refrigerant leak—and perform the necessary repair to thaw the system safely and restore proper operation, preventing future freeze-ups.

This is a common sign of a thermostat malfunction. It could be due to faulty wiring, dead batteries, incorrect calibration, or location in a drafty spot. We'll test your thermostat's accuracy, check its connection to your HVAC system, and either recalibrate it or recommend a reliable replacement to ensure it correctly commands your furnace or heat pump for consistent comfort.

Our local, seasonal maintenance service includes checking refrigerant levels, cleaning coils, inspecting electrical connections, and testing thermostat operation. This proactive approach directly addresses the main causes of frozen pipes and thermostat failures. It improves efficiency, extends your system's life, and helps avoid unexpected breakdowns during our coldest months, saving you money on repairs and energy bills.
