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

Livonia is a western Wayne County suburb with one of the highest homeownership rates in the region — about 87% owner-occupied and 86% single-family detached (ACS 2024). Most homes are 1950s and 1960s ranches and colonials (median year built 1964), and natural gas heats about 90% of them. Long-term owners here often keep furnaces until they fail, so it is common to find units well over 20 years old. Replacement questions usually include right-sizing: many original furnaces were oversized, and homes that have since gained new windows and insulation may be better served by a smaller, higher-efficiency model with a variable-speed blower.

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

Heat Pump vs. Furnace in Wayne County

Southeast 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 Southeast 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 Southeast 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.
