In Warren, about 88% of homes are heated with utility gas and the median home was built in 1965 (American Community Survey 2020-2024, via Census Reporter). Furnace makers say a well-maintained furnace typically lasts 15 to 20 years, so many Warren homes are likely on a second or later furnace. If yours is old, see furnace replacement.

Common questions
How much is a service call for furnace repair?
The sources we found price the whole repair, not the visit fee alone. Angi says small furnace repairs are often billed at a $100 to $200 minimum rather than by the hour, and that labor runs $50 to $150 an hour, with parts extra. That is a national figure, not what a local company will charge. Ask about trip and diagnostic fees before you agree to a visit.

What is the average cost to fix a furnace?
Angi's 2026 national average is $318, based on 27,763 verified projects. Most homeowners pay between $133 and $505, depending on furnace type, the failed part and labor rates. By part, Angi lists a flame sensor at $150 to $250 and an ignitor at $150 to $250 (up to $350 to $500 after hours). These are national figures.

What is the most common problem with furnaces?
We did not find a single ranked list. Angi reports that nearly 41% of customers in its data said their gas furnace or forced-air system did not provide heat or did not get hot enough, followed by a pilot light that is out, odd noises, odd smells, and cycling off too quickly. Furnace makers list the usual suspects: thermostat settings, a dirty filter, pilot or ignition trouble, and a dirty flame sensor.

Who do I call for a furnace repair?
A company that holds a Michigan mechanical contractor's license with a heating classification. The state requires that license to install, alter or service HVAC equipment, with an exception for an owner doing work on their own single-family home. Ask for the license number and check it. This site is not a contractor.
Why is my furnace blowing cold air?
The most common cause Carrier lists is the thermostat fan set to ON instead of AUTO, which runs the blower even when the furnace is not heating. Other causes are a dirty filter (restricted airflow can trip the high-limit switch while the blower keeps running), a pilot light or ignition failure, and a dirty flame sensor. Check that the thermostat is on HEAT and set above room temperature, and change the filter if it is dirty. Gas, oil or electrical parts should be handled by a professional.

What should I do if my furnace will not turn on after a power outage?
Bryant's basic checks: confirm the thermostat is on HEAT with the temperature above the room reading (and that its batteries are fresh), check the furnace power switch and the circuit breaker, replace a dirty filter, and make sure supply and return vents are open. If those do not help, it needs a professional diagnosis. If you smell gas at any point, leave the home and call 911 or your gas utility from outside.
