Heil Furnace

Reliable Furnace Repair in the South Suburbs

When the winter hits New Lenox and the surrounding areas, a working furnace isn't a luxury—it's a necessity. At J.D. HARPS, Inc., we provide honest, straight-talk furnace repair to get your home warm again. We aren't a massive corporate call center; we are your local, family-owned HVAC experts.

Signs You Need a Furnace Repair

You don't always have to wait for the heater to completely break down before calling. Give us a call or send a text if your furnace is showing any of these common symptoms:

  • Blowing cold air: The system is running, but the air coming out of the vents is lukewarm or freezing.
  • Short cycling: The furnace turns on and off constantly without ever properly heating the house to the temperature set on the thermostat.
  • Strange noises: Banging, squealing, or rattling sounds coming from the unit or the ductwork.
  • Yellow burner flame: A healthy gas furnace should have a crisp blue flame. A yellow or orange flame can indicate a dirty burner or incomplete combustion.
  • Unusual smells: A persistent burning dust smell that doesn't go away, or a musty odor. (Note: If you ever smell gas, turn off your system and call your utility company immediately!)

Our Repair Process: Honest Pricing, No Surprises

We respect your time, your home, and your wallet. When you reach out to us with a furnace issue, here is exactly what you can expect:

  1. Reach Out: Call or text us with your furnace's symptoms. We'll get back to you promptly during regular business hours to schedule a diagnostic visit.
  2. Straight-Talk Diagnostics: We arrive when we say we will, inspect your heating system, and figure out exactly what is failing.
  3. Upfront Quotes: We quote the fix before we touch the tools. No hidden fees, no aggressive upsells for a new unit you don't need—just the exact cost to get your heat back on.

Common Furnace Fixes

A malfunctioning furnace doesn't always mean you need an expensive, brand-new system. Often, a furnace blowing cold air is simply a dirty flame sensor, a worn-out hot surface ignitor, or a failing run capacitor on the blower motor. These are straightforward, common fixes our lead technician can handle efficiently to restore your heat and extend the life of your equipment.

Couldn’t have been happier with the outcome when calling on JD HARPS for a furnace-related issue; Eric and Ian were very patient answering my questions and completing what turned out to be fixing the mistake of a previous day that a different company made. Thank you.

My furnace kept shutting off. I left a message during the middle of the night. Cindy from JD Harps called me first thing in the morning. Technician Eric showed up within 30 min. The part was still under warranty. He replaced it and mybill was minimal. Everyone at this company is very knowledgeable and efficient. I could not ask for better service. I'm very grateful for your service.

If I could I'd give this place 6 stars!! Attention all south siders - this is the place to go! I had contacted a few places on Yelp based on the great reviews only to find they didn't service the south side of Chicago. I called a friend of mine (wish I had done weeks earlier) and she recommended JD Harps. Cindy in the office is so very sweet and accommodating and had someone at my house in less than an hour. Needed a new motor for my furnace which needed to be ordered but they came by and installed it less than 24 hours later. Can I say again how awesome they are? Mark told me everything that was wrong and was very professional and courteous. THIS is what a great business looks like.
