HVAC Services Tucson AZ | Call Edward's Heating And Cooling

This is a common issue in Tucson and often points to a faulty reversing valve, which is responsible for switching your heat pump between heating and cooling modes. Our technicians specialize in diagnosing and repairing reversing valve problems to restore your system's proper heating function quickly and efficiently.

Freezing coils are frequently caused by issues like low refrigerant levels, restricted airflow from a dirty filter, or a failing blower motor. These problems force the system to work harder, leading to ice buildup. We perform a thorough inspection to identify the root cause—whether it's a leak, a simple filter change, or a mechanical repair—to prevent future freeze-ups and protect your compressor.

Regular maintenance is key. We recommend a professional tune-up twice a year—before summer and winter—to catch small issues like refrigerant leaks or worn components before they lead to major failures like valve problems or coil freeze-ups. This proactive care improves efficiency, extends your system's life, and helps avoid costly breakdowns during our most extreme weather.
