Heat pumps provide both heating and cooling — when they fail, both functions go offline. A local heat pump repair contractor serving Midland and Midland County handles issues specific to cold-weather operation in Mid-Michigan.

Midland, home to Dow's headquarters, has a median home built in 1971, with about 67% predating 1980 and 67% owner-occupied (ACS 2024). About 79% of homes heat with gas. In May 2020, the failure of the Edenville and Sanford dams flooded parts of the area, and many basements — where furnaces typically sit — took on water. Furnaces that have been submerged generally need to be replaced rather than repaired, because water damages controls, burners and gas valves. Beyond flooding, typical repair needs in Midland include aging furnaces from the 1990s and 2000s with failing igniters, inducers and control boards.

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 Mid-Michigan work harder in cold weather — defrost cycles and auxiliary heat are important in our climate.

Heat Pump vs. Furnace in Midland County

Mid-Michigan'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 Mid-Michigan'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 Mid-Michigan 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.
