Novi has 66,717 residents and 26,801 households (ACS 2024 5-year estimates for Novi city). 26.5 percent of its homes were built before 1980, and the median home was built in 1,993.
66.3 percent of homes are owner-occupied. The median home value is $421,900. Older housing stock tends to need more plumbing, roofing, electrical and water damage work, so these figures help explain local demand. They do not measure it.
Our October 2026 data has 17 HVAC companies with a Novi mailing address: 2.5 per 10,000 residents. A mailing city can differ from the city limits, so treat the ratio as a guide.
Heating and cooling work in Michigan needs a mechanical contractor licence from LARA. Check the company on LARA Verify a License.
A new furnace or air conditioner should be sized for your house. Ask whether the contractor runs a load calculation (often called Manual J) or sizes by the old unit.
Ask for a written quote that lists the model numbers, the removal of the old unit, the permit and any duct or electrical work.
Many equipment warranties need registration within a set time after install. Ask who registers it.
Ask what a tune-up includes. A furnace check before winter is common in Michigan.
