Furnace Maintenance in Ann Arbor, MI

Regular furnace maintenance prevents most of the failures technicians get called out to repair in the middle of a Washtenaw County winter. An annual tune-up before the heating season starts keeps your system running efficiently and catches problems before they become emergencies.

Ann Arbor's heating picture is shaped by the University of Michigan: fewer than half of homes are owner-occupied and only about 42% are single-family detached, with a large share of apartments, condos and converted older houses (ACS 2024). About 71% of households heat with gas and around 26% with electricity. In rentals and multi-unit buildings, furnace repairs often go through a landlord or property manager, and Michigan's housing codes generally require landlords to keep heating systems in working order. Older homes near downtown and campus can have tight basements and long-modified ductwork, while newer condos more often have compact high-efficiency furnaces or heat pumps in closets.

What a Furnace Tune-Up Covers

A complete furnace tune-up for a Ann Arbor home covers: inspecting and testing the heat exchanger for cracks, cleaning the burner assembly, testing the igniter and flame sensor, checking the draft inducer motor and pressure switches, lubricating the blower motor, verifying gas pressure and combustion efficiency, inspecting the flue for blockages, and replacing or inspecting the air filter.

When to Schedule in Southeast Michigan

In Southeast Michigan, schedule furnace maintenance in early fall — September or October — before the first cold snap puts stress on the system. This timing catches problems when you have time to address them rather than scrambling for emergency service in January.
