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

  • The AC runs, but the air coming out is warm
  • The system cycles on and off every few minutes
  • The breaker trips when the AC kicks on
  • Ice on the refrigerant lines or the indoor coil
  • The outdoor unit hums, but the fan doesn't spin

What Moves the Price

  • Refrigerant type and how many pounds it takes
  • The service call or diagnostic fee
  • The part: a capacitor costs a fraction of a fan motor, and a compressor costs far more than both
  • Whether the equipment sits in a tight attic or on a roof
  • Nights, weekends and holidays

We kept the national figures close to unchanged for Ann Arbor using local income, home values and the equipment size this climate needs. Real bids can still come in outside the range, so collect three written quotes.

What the Quote Should Cover

  • Checking refrigerant pressures
  • Diagnosis and electrical testing
  • Replacing the failed part
  • Clearing the drain line if it's clogged
  • A test run

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

  • If you see ice, shut the system off. Running it frozen can kill the compressor.
  • Ask for the per-pound refrigerant price before any work starts.
  • If the compressor is gone on an older unit, get a replacement quote before you pay for the repair.
