Novi Housing Stock

Half the homes in Novi were built before 1992 (Census ACS median), so the typical house is about 34 years old. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. Novi has roughly 18,000 owner-occupied homes, or 68% of households. With a median household income of $110,938 and a median home value of $399,100, local labor rates come out above the national middle in our model.

Between 2020 and 2025, NOAA's Storm Events Database logged 9 hail days and 41 days with damaging thunderstorm winds in Oakland County. 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 breaker trips when the AC kicks on
  • The AC runs, but the air coming out is warm
  • The system cycles on and off every few minutes
  • Water pooling around the indoor unit
  • The outdoor unit hums, but the fan doesn't spin

What Moves the Price

  • The service call or diagnostic fee
  • 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
  • Nights, weekends and holidays
  • Refrigerant type and how many pounds it takes

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. Most repairs don't need a permit. Anyone who opens the refrigerant circuit does need EPA Section 608 certification, and in Michigan the company should carry a state license or registration. Ask for both.

Before You Hire

  • 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.
  • Swap the air filter and check the breaker before you call anyone.
