Johansen Heat & Air | St. George HVAC Repair for Coil Freeze & Heat Pump Issues

In our St. George climate, low refrigerant levels and restricted airflow are the most common culprits. Dust and debris from our environment can clog filters and coils, while slow refrigerant leaks from the intense heat can cause the coil to drop below freezing and ice over. Our technicians perform a thorough diagnosis to pinpoint the exact cause and provide a lasting repair to restore efficiency.

The main sign is your system getting 'stuck' in one mode. You might have cool air blowing when you need heat, or only heat when you want cooling. You may also hear a noticeable hissing sound. This valve is crucial for switching between heating and cooling. Given St. George's heavy reliance on heat pumps, we recommend prompt service to avoid being without your preferred comfort setting.

Absolutely. Our local climate puts extra strain on HVAC systems. A bi-annual maintenance visit from our team is the best defense. We clean coils to prevent freeze-ups, check refrigerant levels and valve operation, and ensure all electrical components are functioning correctly. This proactive care improves reliability, prevents costly emergency breakdowns during our extreme seasons, and extends your system's lifespan.
