Washtenaw County had 9 hail days and 26 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 2 inches across. Hail flattens the thin aluminum fins on condenser coils and cuts airflow. After a big storm, take a look at the outdoor unit; homeowners insurance often covers the damage.

Symptoms Worth a Service Call

Michigan Licensing and Efficiency Rules

Michigan falls in the DOE's North region. New split central air conditioners must meet at least 13.4 SEER2, and heat pumps sold anywhere in the U.S. need 14.3 SEER2 and 7.5 HSPF2. A repair usually goes ahead without a permit, but the tech handling refrigerant must hold EPA 608 certification. Ask the company for its Michigan license or registration number before the visit.

Before You Hire

  • Keep two feet clear around the outdoor unit, including snow.
  • Many heat pumps carry a 10-year parts warranty if they were registered. Find out whether yours was.
  • Book maintenance twice a year, once before summer and once before winter.

Heat Pump Repair Questions from Ann Arbor Homeowners

What does heat pump repair cost in Ann Arbor?

Most bills land between $230 and $1,090, including the service call. A typical visit is about $700. Night and weekend calls cost more.

Why is my heat pump blowing cold air?

For a few minutes during a defrost cycle, that's normal. If it keeps going, the usual causes are a stuck reversing valve, low refrigerant or a thermostat set to the wrong mode.

Is it normal for a heat pump to freeze?

A thin layer of frost in winter is normal, and the defrost cycle should clear it. Heavy ice that stays usually means a defrost control or airflow problem.
