Pontiac Housing Stock

Half the homes in Pontiac were built before 1960 (Census ACS median), so the typical house is about 66 years old. A lot of these homes are on their second or third system by now. The ductwork is usually original, and leaky joints are common. About 11,000 households here own their home, 44.2% of the occupied total. Homes here have a median value of $110,600 and households a median income of $42,791. 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

  • Banging, squealing or rattling from the furnace
  • The thermostat calls for heat and nothing happens
  • A yellow or flickering flame instead of a steady blue one
  • The burners light, then shut off a few seconds later
  • Cold air coming out of the vents

What Moves the Price

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

What the Quote Should Cover

  • A test run through a full heating cycle
  • A safety and combustion check
  • A diagnostic check
  • 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

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