Oakland County had 9 hail days and 41 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. 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 thermostat calls for heat and nothing happens
  • The blower won't stop running
  • Banging, squealing or rattling from the furnace
  • A yellow or flickering flame instead of a steady blue one
  • Cold air coming out of the vents

What Moves the Price

  • Which part failed: a flame sensor costs far less than a control board or blower motor
  • The furnace's age and brand, which affect parts availability
  • The diagnostic or service call fee
  • Whether the part is still under the manufacturer warranty
  • Night, weekend or holiday rates

  • Replacing the part that failed

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

  • Have the model and serial number from the furnace label handy. Parts get ordered faster.
  • Ask whether the diagnostic fee comes off the repair bill.
  • If the furnace is past 15, ask the tech to price both a repair and a replacement.
