READ WHAT OUR CUSTOMERS HAVE TO SAY
“I would like to highly recommend Horsetooth Heating and Air based on our family's experience with them.
From the beginning of the process until the inspection from the city we just had, everything they did was top-notch. Ben came to the house to inspect our heating unit, made his recommendations and informed us of the payment options, which included some pretty hefty rebates. He was patient and kind enough to answer all my questions, and we went forward.
Cory and Ridge were the technicians sent to do the install. From the first handshake they were kind and engaging. They were very interactive with my 3 1/2 year old daughter, even in the midst of their work. They answered questions and Cory was especially helpful in raising my level of awareness of the dangers of carbon monoxide poisoning in the home, which was already rather heightened due to our family's experience with it in another home.
The work was done when it was slated to be done and the inspector commented multiple times about how cleanly the work had been completed. He said (and I am paraphrasing just a touch) it might be the best job he had ever seen.
All in all, HHA did a fantastic job and we feel very blessed to have found them. They are just what you would hope for in a service company; great expertise and high integrity. Thank you HHA for all you did to keep our family warm and safe!”
We really appreciate the professional service we received. The work was completed quickly and cleaned up afterwards. Along with the follow up to correct the inspection requirement.

What Is a Plumbing Inspection?
When was the last time you thought about your plumbing? If you’re like most Greeley, homeowners, it’s probably only when something goes wrong—a leaky faucet, a clogged drain, or worse, a burst pipe.
Why Is My Thermostat Blank?
It is an “Oh no!” moment when you approach your home’s thermostat and see its screen is blank.
Is it serious? Does it mean your furnace, heat pump, or air conditioning is broken? Not necessarily. In fact, most of the time, it is something minor and can be easily fixed.
What Is an Air Handler?
The same goes for a heat pump. The outdoor unit might be in perfect working condition. Still, the heating and cooling process stops without an indoor evaporator coil, connecting refrigerant lines, and a fan to blow conditioned air through ductwork.
