“This is a Great Company with Extraordinary Knowledge and Skills! I had an issue with our boiler and thermostats not working properly. Andrew and Kyle came out and diagnosed the problem and came up with a plan to get heat going for us. Andrew came back out with all the parts and got it going! Andrew is very professional and knowledgeable and an all around great guy! Kyle is the brains and the knowledge he has is amazing!
I would without a doubt Highly Recommend this company and their techs do any work you need and I will be using them from now on!”

I'm not trying to exaggerate, but he may have saved our lives. Thank you to him and Horsetooth Heating & air. I would 100% recommend.”
