Saul A. Naperville, IL

Great experience from start to finish. I called and left a message and within 30 minutes they called me back. The technicians Luis and Gary showed up 2 hours later. Once Luis and Gary arrived they were very friendly and knowledgeable. Luis explained in great detail what are issues with our system were and 30 minutes later our system was working again. We are so happy and impressed with Luis and Gary that we signed up for their maintenance program to help maintain our system in good working condition. Not sure if you can request a technician but if you can ask for Luis.

I had an amazing experience with Kat’s Heating and Cooling! Louie was my service rep, and he went above and beyond to ensure everything was done right. He was professional, knowledgeable, and took the time to explain everything clearly. The service was prompt, efficient, and exceeded my expectations. I highly recommend Kat’s Heating and Cooling—ask for Louie if you want top-notch service!

Continue to be a happy customer! Had my installation by A-Team and maintenance by Kats with the joint team. I have no hesitation in recommending the Kats/A-team to anyone who needs heating or cooling services. The quality is excellent and the prices are reasonable and fair. They explain everything and are very patient. I could not be happier with my decade plus of service from them.

Tommy W. Downers Grove, IL

Can't recommend Kats enough! After communicating with them late Sunday night when my furnace went out, Giovanni and his team we're promptly at my house the next morning to run me through the options. We landed on a replacement and within 30min, they were already at work. The new furnace is great, they improved my current drain and exhaust piping + humidifier placement just to do it, and left the place spotless. Everyone was super friendly, accommodating, and thorough. Will be using them for all my HVAC needs moving forward!

Joe L. Westmont, IL

My furnace went out two weeks ago. I called the company that had a sticker on my furnace, they came out and told me that I needed a new furnace, and quoted me over $5500 for a new one. Wanting to get a 2nd opinion I called Kats Heating and A/C, they came out right away and diagnosed me with a bad capacitor and bad high limit switch. They fixed both of the problems, and my furnace was pumping out heat in no time. I highly recommend Kats Heating, they are a very honest company that performs great work, and beyond amazing customer service.

  • Great Teamwork on AC Installation
    5/5 Stars – Absolute Legends at AC Installation!
    These two techs are absolute heroes! They installed our AC in brutal, fry-an-egg-on-the-sidewalk heat, tackling a tricky coil setup and sheet metal work as pros. Their teamwork and skill were unreal, leaving us with a perfectly running system. The place was spotless when they finished—cleaner than when they started! Super professional, friendly, and took time to explain everything. These guys should get some well deserved recognition for their top-notch work! Highly recommend!

  • A Reasonable Price for Maintenance
    Eddie and Anthony were great! The charge for a furnace tuneup is very reasonable for their comprehensive tuneup. Eddie found that my burner was rusted and needed to be replaced. I’m grateful that he did an extensive tuneup and found issues that my previous technician did not find. I definitely will recommend Kats Heating and Cooling to any needing HVAC repairs or maintenance, they provide quality work and knowledgeable technicians.

  • Furnace Service in a Blizzard
    Anthony came out on a Saturday in a blizzard and took his time to figure out why our furnace unit had not been working and not only fixed it but also fixed our other upstairs unit in the process from the original builder's lack of attention to detail. He was very friendly and personable. We will definitely be using Kats Heating and Cooling again and hopefully Anthony will be the one coming out in the future!!
