When to schedule HVAC work in Ann Arbor
Ann Arbor winters routinely bring sub-freezing temperatures and heavy snow from December through February, so furnaces and boilers run hard for months; scheduling a fall tune-up before the first cold snap helps avoid mid-winter breakdowns. Summers are warm and humid enough that AC systems see steady use from June through September, and homes without ductwork (common in older near-campus houses) often rely on ductless mini-splits or window units.
Permits and HOA rules
Mechanical permits for furnace, boiler, and AC replacement in Ann Arbor are issued through the City of Ann Arbor's Building Department (part of Planning & Development Services), which requires a permit application, licensed contractor information, and inspection for most equipment replacements and new installations.
Licensing and insurance in Michigan
HVAC contractors doing mechanical work in Ann Arbor must hold a Michigan mechanical contractor license issued by the Michigan Department of Licensing and Regulatory Affairs (LARA), which oversees licensing for mechanical, HVAC, and refrigeration contractors statewide.
Older Homes Near Campus Need Special HVAC Care
Many houses in neighborhoods like the Old West Side and Burns Park date back to the early 1900s and were originally heated with steam or hot-water boilers. These systems can still function well but often need specialized repair knowledge that not every modern HVAC technician has experience with.
Retrofitting central air into homes without existing ductwork is a common project in these older neighborhoods, and many homeowners opt for ductless mini-split systems instead of tearing into plaster walls and tight crawl spaces.
Washtenaw County Winters Test Heating Systems
Ann Arbor's location in southeast Michigan means long, cold winters with average lows well below freezing for much of December through February. Furnaces that aren't serviced before the season can fail exactly when they're needed most.
Frozen or cracked heat exchangers, failed igniters, and pilot light issues are common emergency calls during the coldest stretches, and same-day repair availability becomes especially important in January and February.
Working With Licensed Contractors in Michigan
Michigan requires HVAC contractors to hold a mechanical contractor license through LARA, and homeowners should confirm a contractor's license status before signing a contract for major work like furnace or AC replacement.
Permits pulled through the City of Ann Arbor Building Department are typically required for equipment replacement, and a reputable contractor will handle this paperwork as part of the job rather than skipping it.

Common questions
Do I need a permit to replace my furnace in Ann Arbor?
Yes, in most cases a mechanical permit from the City of Ann Arbor Building Department is required for furnace and AC replacement, and the work must be inspected.
Are HVAC contractors in Ann Arbor licensed by the state?
Michigan mechanical contractors are licensed through LARA (the Michigan Department of Licensing and Regulatory Affairs), and homeowners can verify a contractor's license before hiring.
My house near U-M still has a boiler. Can any HVAC company service it?
Not all technicians have deep experience with older steam or hot-water boiler systems common in near-campus homes, so it's worth asking about specific boiler repair experience when getting quotes.
How cold does it get in Ann Arbor, and does that affect furnace costs?
Ann Arbor winters regularly bring sub-freezing temperatures, and furnaces that run heavily for months can wear out components like igniters and blower motors faster, which is a factor in ongoing maintenance costs.
Can I install central air in an older Ann Arbor home without ductwork?
Many older homes in neighborhoods like Kerrytown and the Old West Side lack ductwork, so homeowners often choose ductless mini-split systems as an alternative to a full duct retrofit.
