Common Detroit HVAC emergencies
Call Now — (844) 582-179524/7 dispatch · Detroit-area network
Furnace not igniting or blowing cold
Furnace won't ignite · blowing cold air · short-cycling · burning smell on first startup. In Detroit, a furnace failure in deep winter can lead to frozen pipes within hours. If you smell gas, leave the building immediately and call 911 first.
Pipes freezing while heat is out
Once Detroit indoor temps drop below 55°F, pipes in exterior walls and unheated basements are at risk. If your heat is out and the forecast is below freezing, this is an emergency — restoring heat fast prevents thousands in burst-pipe damage.
AC out during a summer heat wave
Outdoor unit silent · warm air at vents · short-cycling. Even short Detroit summers bring stretches of 90°F+ days — an AC failure during a heat wave is a real-comfort emergency. Most causes are electrical and require a technician.

Detroit's cold-winter climate & your HVAC
This is a heating-dominated Zone 5A (Cool-Humid) climate — the furnace is the most-used appliance in the home for 5–7 months a year. Federal SEER2 13.4 (North Region) minimum applies to new AC equipment, and AFUE 90+ is the de-facto baseline for new gas furnaces in cold-winter regions.

In Detroit, the median home was built in 1947 with a current median value of $76,800. Around 50% of homes are owner-occupied. About 82% of households heat with natural gas vs. 15% electric. The Michigan grid averages $0.20/kWh. Sources: U.S. Census ACS · U.S. EIA state rates.

HVAC in Detroit, MI: local data & sources
Every numerical claim below references a federal, state, or municipal primary source — NOAA climate normals, U.S. Census ACS, the Michigan licensing authority, and your local utility's published rebate program.
NOAA NCEI 1991–2020 Normals
Detroit Metropolitan Wayne County Airport (KDTW) is the NOAA reference station for the city. Per the NOAA NCEI U.S. Climate Normals 1991–2020 (station USW00094847), Detroit records an annual mean temperature of 50.6°F, approximately 6,067.1 annual heating degree days against 847.0 cooling degree days, 34.32 inches of annual precipitation, and 45.0 inches of annual snowfall. The 7.2:1 HDD-to-CDD ratio defines Detroit as one of the most heating-dominated major U.S. cities — a distinctive Great Lakes climate with lake-effect snow, sub-zero polar-vortex events, and long heating seasons that run from October through April.
U.S. Census ACS 2022 5-Year
The U.S. Census Bureau ACS 2023 5-year estimates (Tables B25040 and B25035 for Detroit city, Michigan) report 253,207 occupied housing units with a median year built of 1947 — among the oldest housing stocks of any major U.S. city. Heating-fuel distribution: 81.8% utility natural gas (207,149 units) overwhelmingly dominates, with only 15.4% electricity (38,928 units). Detroit’s pre-WWII bungalows, brick 2-flats, and worker-housing stock were almost universally built around gas-fired systems, and envelope limitations in this era of construction (minimal continuous insulation, leaky windows, knob-and-tube electrical) mean design heating loads are high and well-sized modern furnaces often feel “small” compared to the heritage equipment they replace.
Michigan State Resource
Every HVAC contractor in Detroit must hold a current Michigan Mechanical Contractor License from the Michigan Department of Licensing and Regulatory Affairs (LARA) Bureau of Construction Codes. Per the LARA Application for Mechanical Contractor Examination and Licensing (BCC-11), Michigan issues 10 distinct mechanical-license classifications: “(1) Hydronic heating and cooling and process piping, (2) HVAC equipment, (3) Ductwork, (4) Refrigeration, (5) Limited Heating service, (6) Unlimited Heating Service, (7) Limited Refrigeration and air conditioning service, (8) Unlimited refrigeration and air conditioning service, (9) Fire Suppression, (10) Specialty.” The HVAC Equipment classification “includes ductwork, gas piping and venting” but explicitly excludes “portable self-contained refrigeration equipment and window type air conditioners of not more than 1 1/2 horsepower.” License applicants must demonstrate “a minimum of 3 years or 6,000 hours of performance in EACH work classification” being sought. Permit fees for residential mechanical work are set by the Detroit BSEED (Buildings, Safety Engineering & Environmental Department); contact BSEED at (313) 224-2733 for the current fee schedule.
DTE Energy
Per the DTE Energy residential rebates page for Air Conditioners and Heat Pumps, current dollar amounts are strictly efficiency-tiered: central air conditioner $100 / $200 / $300 at 15.2–15.99, 16–17.99, and 18+ SEER2 respectively; cold-climate air-source heat pump $900 / $1,000 / $1,200 across three SEER2/HSPF2 tiers (16+ SEER2 with 9.1+ HSPF2 hits the top $1,200); ground-source heat pump $600 at 17–19.99 EER2 / $800 at 20+ EER2; standard air-source heat pump $150 at 15.2–17.99 SEER2 / $500 at 18+ SEER2; ductless mini-split $700 at 17–31.5 SEER2 / $1,000 above 31.5 SEER2. The tiered structure rewards specifying higher-efficiency equipment — an 18+ SEER2 AC nets $200 more than the minimum tier. These stack with the federal IRS Section 25C Energy Efficient Home Improvement Credit.
The federal Section 25C Energy Efficient Home Improvement Credit was terminated for installations placed in service after Dec 31, 2025 by the One Big Beautiful Bill Act (Public Law 119-21). State HEAR rebates and utility programs remain in effect. See our HVAC financing options for what's still available.
