Last January, a customer named Dave in Meridian-Kessler called me at 10 PM. His furnace had stopped working, and the indoor temp was dropping fast. He'd already tried changing the filter and resetting the breaker—nothing. When I arrived, I found a dirty flame sensor. A quick cleaning got his heat back on, and Dave was relieved he didn't need a new furnace. That's the kind of fix that makes this job rewarding.
If your furnace is acting up, you don't need a sales pitch. You need someone who shows up, figures out what's wrong, and gives you clear options. That's why we do things a little differently at HVACPros.
Common Furnace Problems We See in Indianapolis Homes
Indianapolis winters put a beating on furnaces. Polar fronts and freeze-thaw cycles stress igniters, heat exchangers, and blower motors. In older bungalows in Broad Ripple or brick ranches in Irvington, you'll often find worn-out parts and aging ductwork. In newer homes in Fishers or Westfield, high-efficiency condensing furnaces can have condensate and venting issues during deep cold snaps.
No Heat or Intermittent Heat
This is the most common call. It usually comes down to a few culprits:
- Pilot light won't stay lit or an intermittent ignition failure. Often a dirty flame sensor or a faulty igniter.
- Thermostat not working - dead batteries, wrong settings, or it just needs to be replaced.
- Blower motor or inducer motor failure - sometimes they just wear out.
Furnace Short Cycling
Your furnace runs for a few minutes and shuts off. That's short cycling. It can be caused by a clogged air filter, a stuck limit switch, or an oversized furnace. In drafty homes with single-pane windows (still common in parts of Indy), it can also be a comfort issue where the thermostat reads the room temp wrong.
Furnace Making Noise
a banging, squealing, or rumbling sound usually means trouble. A popping noise when the furnace starts is often expanding ductwork, but a loud rumble could indicate a cracked heat exchanger. Squealing is usually a failing blower motor bearing. We'll diagnose the noise and tell you what's safe and what needs fixing now.
Our Approach to Furnace Repair
We don't come in with a range and hope. We give you a
Upfront Pricing and Clear Diagnostics
Before we touch anything, we explain what we found. We show you the flame sensor, the limit switch, or the cracked condensate trap. You get a written proposal with options—not a vague estimate. If the repair is simple, we quote it right there. If it's more involved, you know the scope before we start work.
Safety First
We do a combustion analysis and check for carbon monoxide risks. That's non-negotiable. In basements where combustion air is tight, like many homes in Indianapolis, a poorly vented furnace can be dangerous. We make sure your family is safe, and we'll recommend a CO detector if you don't have one near the bedrooms.
Quality Parts and Clean Work
We use OEM-grade parts when available—not cheap knockoffs that fail in a year. And we clean up after ourselves. You'll never find greasy footprints on your floor.
When to Repair vs. Replace
This is the big decision. Generally, if your furnace is less than 10 years old and the repair cost is less than half the price of a new one, repair makes sense. Older units (15+ years) that need major repairs—like a heat exchanger—are often better replaced. We'll talk through your situation, including your local utility costs (Citizens Energy Group rates) and what efficiency upgrades might save you in the long run.
A customer in Greenwood had a 20-year-old furnace that kept getting limit switch faults. We showed her that the repair would only band-aid the problem. She opted for a new high-efficiency furnace, and her gas bill dropped 30% that winter.

We cover Indianapolis and the surrounding suburbs: Carmel, Fishers, Zionsville, Westfield, Noblesville, Greenwood, Brownsburg, Avon, and Plainfield. Wherever you are, we'll get there quickly.
