Hiring an HVAC Contractor in Ann Arbor: A Step-by-Step Guide
Hiring the right HVAC contractor in Ann Arbor involves more than picking the first name that comes up in a search. This guide walks through the key steps, from licensing checks to permit requirements.

Step 1: Confirm Michigan Licensing
Before hiring, confirm that the contractor holds a valid Michigan mechanical contractor license through LARA. This is a basic but important step for any HVAC work in Ann Arbor.
Unlicensed work can create problems later, especially if you need permits pulled for equipment replacement.
Step 2: Understand Permit Requirements
Most furnace, boiler, and AC replacement projects in Ann Arbor require a mechanical permit through the City of Ann Arbor Building Department, followed by an inspection.
Ask your contractor whether they will handle the permit application as part of the job, which is standard practice for reputable companies.
Step 3: Ask About Experience With Your Home Type
Older homes near the University of Michigan campus may have boilers or limited ductwork, so ask potential contractors about their specific experience with these systems.
For more background on typical local pricing, see our Ann Arbor HVAC guide.
Step 4: Compare Quotes and Ask Questions
Get written quotes from a few contractors that detail the scope of work, equipment specifications, and warranty terms before making a decision.
