Heat pumps provide both heating and cooling — when they fail, both functions go offline. We diagnose and repair heat pump systems across Lebanon and Warren County, including issues specific to cold-weather operation in Miami Valley.
Heat Pump Problems We Fix
Common heat pump failures: reversing valve problems that prevent switching between heating and cooling, refrigerant leaks, defrost board failures that cause ice buildup on the outdoor unit in cold weather, compressor issues, and auxiliary heat problems. Heat pumps in Miami Valley work harder in cold weather — defrost cycles and auxiliary heat are important in our climate.
Heat Pump vs. Furnace in Warren County
Miami Valley's cold winters push heat pumps to their efficiency limits at low outdoor temperatures. Below around 35-40 degrees, heat pump efficiency drops significantly and auxiliary or emergency heat carries the load. If your heat pump is running but not keeping up in cold weather, the auxiliary heat source may be the issue.
