Rochester Hills particulars
Rochester Hills handles permits online from start to finish. The Building Department, 1000 Rochester Hills Dr., 248-656-4615, lists a separate Mechanical Permit document, accepts documents and fees through BS&A Online, and schedules all inspections exclusively online. A contractor without a BS&A account cannot simply phone in an inspection. Housing here skews newer: 41.7 percent of homes were built before 1980. Older homes more often have older furnaces and ductwork, so a house from the 1990s or later may raise different questions, and the median home value is $377,400.
DTE Electric is the only electric utility whose territory covers the city. Gas is mostly Consumers Energy, with a small overlap of SEMCO Energy Gas, so a boundary address needs checking. Consumers Energy's 2026 chart applies to gas furnace replacements (installs January 1 to December 31, 2026; funds limited). We saw no rebate run by Rochester Hills itself. Rochester Hills has no station of its own in our table; the nearest, Detroit Metro airport, averages about 6,067 heating degree days (base 65 F). Rochester, Auburn Hills and Troy are close, and the AC repair page covers the cooling side.
Emergency HVAC in Rochester Hills: what to know
Consumers Energy's first instruction in Rochester Hills is to get out; after that comes no electric device, then 911 and then 800-477-5050. For a sounding carbon monoxide alarm, the Consumer Product Safety Commission says to move to fresh air and call 911. Nearly all the gas sample points we checked were Consumers only, with a handful overlapping SEMCO, so check the bill.
Rochester Hills handles permits online from application to inspection, which helps once the emergency has passed. A swap of the furnace still requires a mechanical permit under LARA's minor-parts exception. For a cold house tied to a shutoff, our winter utility shutoff guide sets out what we could document. The Building Department at 248-656-4615 can say which permit document applies.
Permits for emergency hvac in Rochester Hills
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: turn the furnace off at the switch only if it is safe to reach, and otherwise leave it alone and go outside.
- 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.
