On the cooling side, a 2,000 sq ft house here usually needs around 2.5 tons. A tight, well-insulated house may get by with half a ton less.

Troy Housing Stock

Census figures put the median build year in Troy at 1977, so a typical house here has about 49 years on it. A lot of these homes are on their second or third system by now. The ductwork is usually original, and leaky joints are common. Troy has roughly 25,000 owner-occupied homes, or 74.2% of households. Homes here have a median value of $396,800 and households a median income of $119,299. Those two numbers drive the labor adjustment in our estimate.

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 system cycles on and off every few minutes
  • Water pooling around the indoor unit
  • Ice on the refrigerant lines or the indoor coil
  • The breaker trips when the AC kicks on
  • The AC runs, but the air coming out is warm

What Moves the Price

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

We raised the national figures about 10% for Troy 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

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

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

  • 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.
  • If the compressor is gone on an older unit, get a replacement quote before you pay for the repair.
