  “I can’t recommend this company highly enough! They were incredibly responsive – they came out to assess my furnace and, amazingly, had it replaced the very next morning. It was fantastic service, and I was glad I didn’t have to be there when they did the work.” report abuse

  “My air conditioning unit finally gave out during that really intense heatwave in June 2025 – it had been running perfectly well for the past 40 years, which was fantastic. I ended up calling a few different heating and cooling companies to get it looked at.” report abuse

  Collin was fantastic – he really took care of our central AC problem. He was so friendly and clearly knew what he was doing, quickly diagnosing and replacing the broken contactor. We’re absolutely thrilled with the results and the air is working perfectly now! report abuse

  “I’m really disappointed with my experience with the KComfort Carrier AC I bought for $7000 four years ago. When it stopped working, I contacted them to inquire about the warranty, but was immediately told I couldn’t get any assistance because my name was on their ‘no service’ list. It was incredibly frustrating to be denied support after investing so much money in their product.” report abuse
