NOAA storm reports for Oakland County show 9 hail days and 41 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 1.25 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. Oakland County also had 4 tornado days in that period.

Symptoms Worth a Service Call

  • The AC runs, but the air coming out is warm
  • The system cycles on and off every few minutes
  • Ice on the refrigerant lines or the indoor coil
  • Water pooling around the indoor unit
  • 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
  • Nights, weekends and holidays
  • Whether the equipment sits in a tight attic or on a roof
  • The part: a capacitor costs a fraction of a fan motor, and a compressor costs far more than both

What the Quote Should Cover

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

  • Swap the air filter and check the breaker before you call anyone.
  • Ask for the per-pound refrigerant price before any work starts.
  • If you see ice, shut the system off. Running it frozen can kill the compressor.
