Furnace Repair South Bend Homeowners Trust for Honest, Reliable Heat

There is never a "good" time for your heating to fail, but in Northern Indiana, it always seems to happen during a record-breaking cold snap or right before a holiday.

If you’re looking for furnace repair in South Bend, you’re likely feeling two things: cold and skeptical. You’re worried about how much this will cost and whether the technician who shows up is going to tell you that your entire system is "totaled" just to push a new sale.

At I & M Heating and Cooling, we do things differently. We are a "Fix First" company. Our technicians are trained to find the mechanical root of the problem and get your heat back on as efficiently as possible. If your furnace has life left in it, we will save it.

FAQ

Frequently Asked Questions About Furnace Repair

Most common repairs—like replacing a capacitor, a flame sensor, or an ignitor—typically fall between $150 and $400. Major components like a blower motor can cost more. We always provide the exact price upfront.
In many cases, yes! If the heat exchanger is intact and the repair cost is reasonable, we can often get several more years out of an older unit. We follow a "Fix First" philosophy regardless of the age of your equipment.
This could be a pilot light issue, a failed thermocouple, or a limit switch that has tripped because the system is overheating. Our techs can usually diagnose this in under 30 minutes.
We recommend a professional tune-up once a year, ideally in the fall before the South Bend winter hits. This prevents about 80% of the repair calls we receive.
Yes. Whether your South Bend home uses a traditional gas furnace, an electric heat pump, or a boiler system, our team has the specialized tools to repair it.
If you smell a "rotten egg" odor, exit the house immediately and call NIPSCO or your local emergency services. Once the gas is shut off and the home is safe, call us to repair the leak or the unit.
