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 Dublin and Franklin County, including issues specific to cold-weather operation in Central Ohio.

Dublin sits along the Scioto River in Franklin County and has grown into one of central Ohio's more affluent suburbs, home to several corporate headquarters and known for hosting the annual Dublin Irish Festival. Its housing stock reflects that growth trajectory — a large share of homes built from the 1980s onward to progressively higher construction standards, with larger square footage and more sophisticated multi-zone HVAC setups than typical of older, smaller Franklin County housing. Central Ohio's winters bring sustained cold and regular snowfall, and Dublin's newer, larger homes often mean a bigger total heating load per house than older, more compact housing elsewhere in the county, even when the equipment itself is more efficient. Because so much of Dublin was built under more recent energy codes, furnace problems here more often trace to a failed component in comparatively newer equipment than to an aging original system nearing the end of its life.

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 Central Ohio work harder in cold weather — defrost cycles and auxiliary heat are important in our climate.

Heat Pump vs. Furnace in Franklin County

Central 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.

Frequently Asked Questions

Why is my heat pump running but not keeping the house warm?

In cold weather, this is often the auxiliary or emergency heat not engaging when it should, since heat pump efficiency drops significantly below roughly 35-40 degrees outdoor temperature. It can also point to a refrigerant leak or a failing reversing valve. We check the auxiliary heat circuit first since it's the most common cause in Central Ohio's climate.

Why is there ice building up on my outdoor heat pump unit?

Some frost is normal in cold, humid weather, and the unit should periodically run a defrost cycle to clear it. Heavy ice that doesn't clear on its own usually means the defrost board or a related sensor has failed. Running the unit with heavy ice buildup for an extended period can damage the compressor, so it's worth having it checked promptly.

Do heat pumps work in cold Midwest winters?

Yes, but efficiency drops as outdoor temperatures fall, which is why most systems in Central Ohio pair a heat pump with an auxiliary or backup heat source for the coldest days. If your heat pump seems to struggle every winter rather than only on the coldest days, that's usually a sign of a problem rather than normal behavior.

What's the difference between repairing a heat pump and repairing a furnace?

A heat pump is closer to an air conditioner in its components — it has a compressor, refrigerant, and a reversing valve that switches it between heating and cooling. A furnace burns gas and has an entirely different set of parts: igniter, flame sensor, heat exchanger. Diagnosing a heat pump problem requires refrigerant-side knowledge, not just combustion knowledge.
