  • 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!!
