Southfield particulars
Ordinance No. 1656 puts Southfield's rental furnaces under inspection. One- and two-family rented dwellings must be registered and inspected every three years, with a fine of up to $500 for non-compliance. The rental page links a Furnace/Boiler Certification form for a mechanical contractor registered with the city, recording carbon monoxide parts per million, heat exchanger condition and venting. Whether every rental certificate requires it is our inference; call Building and Safety Engineering at (248) 796-4177.
Heating is its own permit: the city says heating systems need a permit separate from the other trades. The Building Department is at 26000 Evergreen Road, 248-796-4100. BSAOnline.com is linked, but the pages do not say heating applications are filed there. About 80.1 percent of homes predate 1980. For power, DTE Electric is the only utility on the map for Southfield, with gas mostly from Consumers Energy; a border address needs checking.
Consumers Energy's 2026 chart covers gas furnaces (installs January 1 to December 31, 2026; amounts can change without notice). Our nearest station for Southfield is Detroit Metro airport, which normals out near 6,067 heating degree days (base 65 F). Beverly Hills and Oak Park are next to Southfield. The boiler repair page covers hot-water systems.
Emergency HVAC in Southfield: what to know
For gas, the order is out, then 911, then Consumers Energy at 800-477-5050, with no phone or switch used inside. A carbon monoxide alarm means fresh air and 911, per the Consumer Product Safety Commission. Most Southfield gas service points we sampled were Consumers only, so confirm the company on your bill.
Southfield's Ordinance No. 1656 requires one- and two-family rentals to be registered and inspected every three years, with a Furnace/Boiler Certification form that a registered mechanical contractor completes. A fine of up to $500 follows non-compliance. If heat has gone out because of a shutoff, the winter utility shutoff guide describes the programs we could document. An emergency replacement is a heating permit at 248-796-4100.
Permits for emergency hvac in Southfield
LARA's permit rule excepts replacement of minor parts, so an emergency part swap generally needs none.
What counts as an emergency
- You smell gas: leave, call 911 and your gas utility from outside.
- A carbon monoxide alarm sounds or several people feel flu-like without a fever.
- No heat but the house is not yet cold, with no smell and no alarm: check the thermostat and filter, then book a visit.
- A noisy furnace that still heats.
Checks while you wait
Try this first: as a tenant, ask whether the landlord's furnace and boiler certification is current.
- Set the thermostat to heat, above the room temperature, with fresh batteries if it takes them.
- Change or clean the filter; ENERGY STAR says monthly.
- Note any light pattern or code on the furnace and stop; do not remove panels or relight after any gas smell.

How we estimate costs: the figures here are estimates, not quotes, built from BLS wages, published city permit fees and federal energy-cost evidence. We are collecting the prices Michigan heating and cooling companies publish; we have not yet collected quotes from them, and we will say how many and from when once we do. Estimated range. Built from national published ranges (1 source), adjusted by Michigan's HVAC technician wage ratio to the US (1.00, BLS May 2025), plus the local permit fee where the city publishes one. Not a quote. We have too few Michigan company prices yet to show a range. Full method.
Questions about emergency hvac
What counts as an emergency HVAC repair?
Those go to 911 and your gas utility first. A furnace that has stopped in freezing weather is urgent but is a call to a heating company once you are sure there is no smell and no alarm.
What should I do if I smell gas near my furnace?
DTE and Consumers Energy both say 911 first. Do not look for the source or use switches, appliances or phones inside, and stay out until responders or the utility say it is safe.
Can I cancel a repair contract signed during an emergency?
Michigan law lets a buyer cancel a home solicitation sale until midnight of the third business day, but not when you request the work without delay because of an emergency and the conditions are met. It covers sales solicited at your home, which is our reading of the statute.
