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

Hilliard sits on the western edge of Franklin County along the Hayden Run and Cosgray Road corridors, and has been one of the fastest-growing suburbs in the Columbus metro over the past two decades, with new residential development continuing to push toward the county line. That growth pattern means a large share of Hilliard's housing was built recently enough to follow more current energy codes and duct-design standards than older Franklin County neighborhoods, though the town's original historic core near downtown still carries homes old enough to need original equipment replaced. Central Ohio's winters bring sustained cold and meaningful snowfall most years. Because Hilliard's newest subdivisions were built in a tighter, more recent window than the rest of the county, furnace equipment ages here cluster more predictably by neighborhood — meaning a wave of original systems reaching 12 to 15 years old can show up across an entire subdivision within a similar span.

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.
