Pontiac Weather and HVAC Load
Pontiac logs 6,474 heating degree days and 720 cooling degree days in a normal year, based on the closest NOAA weather station. Heating is the bigger job here, and furnaces and heat pumps in Pontiac put in far more hours than the air conditioner. A normal year brings 135 nights at or below freezing and 10 days over 90°F. Snowfall averages about 36 inches. For a 2,000 sq ft house, this climate points to a heating load somewhere near 65,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.

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.

Michigan Permits, Efficiency Rules and Rebates
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. Equipment replacements in Pontiac generally need a mechanical permit, and a reputable contractor will pull it for you. Ask for their Michigan license or registration number and a certificate of insurance with the quote. The federal 25C tax credit ended for equipment installed after December 31, 2025, so incentives now come mostly from utilities and state programs. Check your electric and gas utility's rebate page before you pick equipment.
Before You Hire
- For a steam system, hire a contractor who works on steam regularly.
