Novi Weather and HVAC Load
Novi logs 6,867 heating degree days and 572 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 Novi put in far more hours than the air conditioner. A normal year brings 146 nights at or below freezing and 11 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 70,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.

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.

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 Novi 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
- Ask your gas or oil company about rebates on condensing boilers.
- A combi boiler frees up space and replaces your water heater.
- Ask for a heat-loss calculation. A lot of old boilers are much bigger than the house needs.
