When a heating system fails in Washtenaw County's winters, it becomes an urgent problem quickly. A local heating repair contractor serving Ann Arbor handles gas furnaces, electric furnaces, heat pumps, and boilers — same-day service when available.
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.
Heating Systems Serviced
Gas furnaces are the most common heating equipment in Southeast Michigan — typical failures include igniter failure, heat exchanger cracks, faulty pressure switches, and control board issues. Heat pump heating problems often show up as reversing valve failures or defrost issues. Boilers develop circulation pump failures, zone valve problems, and pressure issues. A qualified technician diagnoses accurately before recommending any repair.
Gas or heating bills climbing even though usage habits haven't changed
A furnace working harder to hold the same temperature is a common early sign of declining efficiency, often well before it makes unusual noises or fails outright.
Uneven heating between rooms, or the system running in longer cycles than it used to
This can point to airflow, ductwork, or aging-component issues — worth a diagnostic look rather than just adjusting the thermostat higher.
The furnace is approaching or past the typical 15-20 year service life
Even a furnace that's still technically running may be a good candidate for proactive replacement once it's in this age range, especially given the 2028 efficiency-standard change on the horizon.
Safety Checks During Every Service Call
Gas heating systems in Washtenaw County require careful attention to combustion and venting. A cracked heat exchanger can allow carbon monoxide to enter the living space. Heat exchangers are checked as part of every furnace service call in our network, with any safety concerns flagged immediately — contractors carry CO detection equipment on every service vehicle.
