John B. Simpson Company: Top-Rated HVAC Services Serving Sturgis, MI 49091

Improper installation often leads to issues like incorrect refrigerant charge or restricted airflow. In our Sturgis climate, this imbalance forces the system to work too hard, causing the evaporator coil to drop below freezing. Moisture then freezes on the coil, blocking airflow and shutting down your cooling. Our repair experts diagnose and correct these root installation errors to prevent recurring freeze-ups.

First, turn the system to 'off' at the thermostat and switch off the breaker to allow the ice to melt completely—this can take several hours. Running it while frozen can damage the compressor. Once thawed, check and replace dirty air filters, a common culprit. If it freezes again, call us. Our repair service will investigate for deeper issues like low refrigerant or blower motor problems, which are often tied to the original installation quality.
