Heat pumps provide both heating and cooling — when they fail, both functions go offline. Get connected with technicians who diagnose and repair heat pump systems across Mentor and Lake County, including issues specific to cold-weather operation in Northeast Ohio.
Mentor sits on Lake Erie in Lake County and is home to Lawnfield, the historic estate of President James Garfield, a landmark that sits amid a city that has grown substantially from a smaller lakefront community into one of the county's largest residential bases. Lake County as a whole sits in one of Ohio's most active lake-effect snow zones, since it's positioned almost directly downwind of the lake's greatest fetch distance, and Mentor's heating season runs correspondingly long and demanding compared to inland Ohio cities. The city's housing spans older lakefront-adjacent homes built well before central heating was standard, through mid-century development, to newer subdivisions further from the shoreline. Because lake-effect snow bands here can be intense but highly localized — heavy in Mentor while a town twenty miles inland sees far less — a furnace failure during one of these events can strand a household for longer than the same failure would in a less snow-exposed part of the state.
Common Heat Pump Problems
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 Northeast Ohio work harder in cold weather — defrost cycles and auxiliary heat are important in our climate.
Heat Pump vs. Furnace in Lake County
Northeast Ohio'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.
