Furnace Installation and Repair in Orland Park

Orland Park isn’t known for its comfortable winters. With temperatures diving below freezing point, you’ll need a robust furnace. If you suffer from allergies, gentle humidification can reduce air contaminants without breaking the bank. Let Comfort Zone help you meet Illinois’ minimum efficiency standards and clearance so that you can finally achieve affordable heating. Quality installation is safe installation. That’s why we offer a one-trip, fixed-right guarantee.  

A few symptoms tell you that your furnace needs repair:

  • Your furnace has an unusual scent.
  • Your pilot light is discolored.
  • Your furnace isn’t generating enough heat.
  • You’re hearing odd noises.

Furnace Inspections and Tune-Ups in Orland Park

Annual inspections ensure that your furnace achieves its full service life and remains energy-efficient. Getting behind on your inspection schedule can create dangerous health risks, including carbon monoxide poisoning. If your furnace has endured a long, lazy summer, you probably need a tune-up before the chilly season strikes. Call us at if you need to put your idle furnace back in service. Our qualified professionals handle services so well they’ve earned an A+ BBB rating because service excellence isn’t a goal for us. It’s a necessity.

Very quick response time! I noticed the failure of my hot water heater at 7 pm one evening and had a new hot water heater installed and ready to go by 11 am the next morning. Great communication, clear recommendations, and took the time to explain details about the equipment that was ultimately installed.

Ryan H.

We have worked with Comfort Zone for about 4 years and are completely satisfied with the quality of service they provide. They recommended and installed a new AC unit, and provide us an annual furnace and AC cleaning and inspection service. We highly recommend this company for residential heating and cooling needs.
