It very well could be. A faulty reversing valve is a common reason a heat pump fails to switch to heating mode, leaving you with cool air when you need warmth. This part is crucial for the refrigerant flow reversal that provides heat. Our technicians can diagnose if the valve is stuck, leaking, or has an electrical fault and perform the precise repair to restore your system's proper function.

Evaporator coil freeze-ups are often caused by restricted airflow or low refrigerant levels. In our area, clogged air filters from pollen and dust, dirty coils, or a failing blower motor can limit airflow, causing the coil to get too cold. Low refrigerant (a leak) has the same effect. We'll identify the root cause—whether it's a simple filter change, a coil cleaning, or a leak repair—to prevent recurring freeze-ups and system strain.

Our comprehensive diagnostic service for issues like reversing valve failures or coil freezes includes a full system performance check. We'll measure refrigerant pressures and levels, check electrical components and valves, inspect airflow at the filter and coil, and assess the thermostat. You'll get a clear, honest explanation of the problem, your repair options, and a transparent quote before any work begins, ensuring you understand exactly what's needed to fix your local HVAC issue.
