HVAC companies in Detroit, MI
Compare up to three local Detroit HVAC contractors from Henry's vetted bench — AC repair, furnace and heat pump service, and full system replacement.
Detroit's housing stock skews old — bungalows in Bagley, brick colonials in Boston-Edison, and Indian Village mansions built decades before central air existed. That history shapes every HVAC job in the city: boiler-to-forced-air conversions, undersized ductwork, and steam radiators that need specialized service techs, not just generalists. Add Michigan's brutal furnace season and Detroit's own mechanical permit process through BSEED, and hiring the right contractor matters more here than in most metros. This guide covers what HVAC work actually costs in Detroit in 2026, how permitting and licensing work, and which neighborhoods carry which quirks. See our companion guides: How to Hire an HVAC Contractor in Detroit, HVAC Repair Cost in Detroit, AC Repair Cost in Detroit, and How to Vet HVAC Companies in Detroit.
The Henry Standard
Every HVAC contractor in our network agrees to three things.
Show up
Call back. Keep appointments. And if something changes, communicate it.
Quote honestly
Equipment, scope, permit, and price in writing — so you know what you're agreeing to.
Finish the work
See the job through, pull the permit, and pass inspection before calling it finished.
Nothing revolutionary. Just the way we believe doing business should still be done.

When to schedule HVAC work in Detroit
Detroit sits in a cold climate zone with design temperatures often near 0-5°F in January, meaning furnaces run near max output for weeks at a time. Undersized or aging furnaces in older homes struggle through polar vortex events, so load calculations (Manual J) matter more than swapping in a like-for-like unit. Summers are shorter but increasingly humid, and homes without existing ductwork need real retrofit planning — not a same-day install — to add central air.
Permits and HOA rules
Mechanical work in Detroit (furnace replacement, boiler work, new ductwork, AC installs) requires a permit from the Buildings, Safety Engineering and Environmental Department (BSEED), pulled by a City of Detroit-licensed mechanical contractor through the Accela permit portal 1. Homeowners should confirm their contractor is pulling the permit rather than skipping it — unpermitted furnace and boiler swaps are common in older housing stock and can complicate insurance claims and resale. BSEED's trade permit info, including boiler-specific permits, is at 2 and 3.
Licensing and insurance in Michigan
Michigan requires mechanical contractors to hold a state license issued by the Department of Licensing and Regulatory Affairs (LARA), verifiable through the state's Accela license lookup tool 4 or LARA's licensing search page 5. Detroit additionally requires contractors working within city limits to hold a City of Detroit mechanical contractor license before BSEED will issue a permit — always ask to see both before signing a contract.
Why Detroit's older housing stock changes the HVAC job
Neighborhoods like Boston-Edison, Indian Village, and Palmer Woods were built in the 1910s-1930s around steam or hot-water boilers and radiators, not forced-air ducts. Adding central air to these homes means either running new ductwork through plaster walls and tight chases, or installing a ductless mini-split system zone by zone — a very different (and often pricier) job than a straightforward AC swap in a newer suburb.
In smaller bungalow neighborhoods such as Bagley and East English Village, furnaces are usually forced-air already but original ductwork can be undersized for modern high-efficiency equipment, so a good contractor checks duct capacity before quoting a furnace swap, not after installation causes airflow complaints.
Permits and licensing specific to Detroit
BSEED requires a mechanical permit for furnace, boiler, and ductwork changes, filed by a contractor with both a Michigan LARA mechanical license and a City of Detroit mechanical contractor license through the Accela portal.
Ask any contractor bidding your job to provide their LARA license number and City of Detroit contractor license number up front, and verify both before signing — this is the single easiest way to avoid unlicensed work in a market where permit skipping on furnace and boiler jobs is unfortunately common.
DTE Energy rebates worth asking about
DTE Energy, Detroit's gas and electric utility, offers rebates for high-efficiency equipment: up to $400 for a 98% AFUE furnace, $200-$400 for lower tiers, $50 for a qualifying smart thermostat, and $75 for a furnace/boiler tune-up with combustion analysis 6.
DTE also rebates air-source heat pumps as an all-season replacement for aging AC and gas furnaces; contractors enrolled in DTE's Find a Contractor tool handle the paperwork directly 7. Always ask your contractor whether they're a DTE-participating contractor before signing, since non-participating installs can miss rebate eligibility entirely.

Common questions
Do I need a permit to replace a furnace in Detroit?
Yes. Furnace and boiler replacements require a mechanical permit from BSEED, filed by a City of Detroit-licensed mechanical contractor through the Accela portal.
Can I add central air to an older Detroit home without existing ductwork?
Yes, but it typically costs more than a standard AC swap. Homes in Indian Village, Boston-Edison, and similar neighborhoods usually need either new ductwork run through existing chases or a ductless mini-split system installed zone by zone.
How do I verify an HVAC contractor's license in Michigan?
Use LARA's license lookup tool to confirm their state mechanical contractor license, and separately confirm they hold a City of Detroit mechanical contractor license, which BSEED requires for permits inside city limits.
What DTE rebates apply to furnace or heat pump replacement in Detroit?
DTE offers rebates up to $400 for a 98% AFUE furnace, plus rebates for qualifying air-source heat pumps and smart thermostats, generally handled by DTE's participating contractors.
Why is my old boiler more expensive to service than a furnace?
Steam and hot-water boiler systems, common in Detroit's pre-war housing stock, require technicians experienced with radiators, circulator pumps, and steam traps — a smaller pool of specialists than standard forced-air furnace techs, which pushes both diagnostic and repair costs higher.
