Westland particulars
Landlords in Westland need a mechanical contractor's signature. Rental dwellings cannot be occupied without a Certificate of Compliance, registered every three years, and the fee includes a Furnace Safety and Carbon Monoxide Test; a Furnace/Boiler Certification form must be completed by the hired mechanical contractor before final approval. Permits come from the Building Division, 36300 Warren Road, 734-467-3210. Its mechanical application is a PDF, and registered contractors use the online tool for payments and inspection scheduling; the page does not say applications themselves are online.
The form revised July 1, 2026 lists a $100 administration fee and a $100 minimum permit fee, with $83 for a residential furnace up to 75,000 BTU and $99 up to 155,000 BTU. Whether the minimum lifts a single $83 item is the city's call. Westland lists the 2021 Michigan Mechanical Code and the 2015 Michigan Residential Code as adopted. DTE Electric is the only electric utility whose territory covers the city, and gas is mostly Consumers Energy, so check your address.
We use the Detroit Metro airport normals as the nearest station in our set: about 6,067 heating degree days a year (base 65 F). About 72.6 percent of homes predate 1980, and older homes more often have older furnaces and ductwork. Garden City and Wayne are close; our furnace repair page is the heat-first start.
Furnace repair in Westland: what to know
Westland's heating load is the Detroit Metro airport normal, our nearest station: about 6,067 heating degree days a year at base 65 F. Of 117 gas service points we sampled, 103 fell in Consumers Energy territory only and 14 in an overlap with DTE Gas, so check your own bill before assuming a utility. About 72.6 percent of homes predate 1980.
Replacement permits come from the Building Division at 36300 Warren Road, 734-467-3210, on a PDF mechanical application revised July 1, 2026. It lists a $100 administration fee and a $100 minimum permit fee, with $83 for a residential furnace up to 75,000 BTU and $99 up to 155,000 BTU. Whether the minimum raises an $83 single-item permit is the city's decision, so ask when you apply.
Permits for furnace repair in Westland
LARA's rule says mechanical work needs a permit except for replacement of minor parts, so a repair that swaps a part generally does not, while replacing the furnace does (our reading of LARA's exemption list).
Furnace problems that cannot wait
- You smell gas: leave, then call 911 and your gas utility from outside.
- A carbon monoxide alarm is sounding: get into fresh air, call 911 and stay out until told it is safe (see the carbon monoxide guide).
- Several people have flu-like symptoms without a fever; SEMCO lists headache, fatigue, nausea and dizziness as carbon monoxide symptoms.
- No heat in freezing weather: see emergency HVAC repair.
- A furnace that heats but runs louder than it used to, with no gas smell and no alarm.
Three checks before you call
Try this first: have the furnace's input rating written on the quote, because the permit fee changes at 75,000 BTU.
- Set the thermostat to heat, above the room temperature, with fresh batteries if it takes them.
- Check the filter and change or clean it; ENERGY STAR says to do this monthly.
- If it still will not start, note any light pattern or code and stop. Do not remove panels or relight anything after a 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 furnace repair
What is the average lifespan of a furnace?
The federal and ENERGY STAR pages we could read give none. ENERGY STAR does say equipment more than 10 years old should be evaluated by a professional HVAC contractor, which is a reason to ask for an inspection and gives no expiry date.
How much does furnace repair or a service call cost in Michigan?
The first row of the cost table is a statewide estimate, a model and not a quote. The rows below show technician wages, a Michigan mean of $31.01 an hour (BLS, May 2025), which is pay, not a charge. Ask what the visit fee covers and get the repair price in writing before work starts.
What is the $5,000 rule for furnaces?
Contractors and homeowners pass it around, but no federal or state page we read states it. The repair-or-replace tool shows it only as a labeled rule of thumb; ENERGY STAR's 10-year evaluation advice is the sourced alternative.
