Chief/Baur Heating & Air Conditioning - Bloomington's Experienced HVAC Repair

Frozen coils are a common issue here, often caused by restricted airflow from dirty filters or blocked vents, or by low refrigerant levels. Our technicians first safely thaw the system, then perform a thorough inspection to pinpoint the exact cause—whether it's a simple filter change, duct cleaning, or sealing a refrigerant leak—to prevent it from happening again.

Signs of a leak include reduced cooling power, longer run times, ice on the refrigerant lines or evaporator coil, and a noticeable hissing sound. Since refrigerant is essential for your AC to work, a leak will only worsen. We use specialized electronic leak detectors to quickly and accurately find the source so we can make a proper, EPA-compliant repair.

The first step is to turn the system off at the thermostat to prevent further damage to the compressor. Let the ice melt completely, which can take several hours. Then, call us. Running a frozen system can cause serious, costly damage. Our team will diagnose the root cause—be it airflow, refrigerant, or a mechanical fault—and get your Bloomington home cool and comfortable safely.
