Experience the Best HVAC Contractors in Windsor and Northern Colorado

I called Halo when my water heater started leaking from the bottom. They responded quickly and reviewed my options for a new water heater. Steve was able to locate the particular water heater I wanted and had the old one removed and the new one Installed that day. I can't thank them enough for the prompt service. I highly recommend Halo and will use them again if the need arises. They were very courteous and professional.

Steve, the HALO technician, was great. He did a quick view of our furnace and could see it was malfunctioning. He was very transparent, showing me his initial findings, explaining how the furnace should work and trying a step to correct the problem. When that didn't work, he inspected the wiring more closely and found a crimped wire leading into the burner assembly. He replaced the wire and the furnace resumed normal operation. Thanks much, Steve!

They were on time, friendly and competent. In one day put in new furnace, took away old one. Permit was issued and city inspector said they did a really good job. I will use Halo for all my future HVAC needs.

Chernet and Steve were incredibly professional and compassionate! They thoroughly explained the issue with my furnace, made sure that i understood, and then showed me what they found.

I’m am so impressed with the quality and depth of service that I received. The details about what was being done and how the system works were so helpful to me and the most valuable as I know how to help diagnose my own system.
They tested everything and were able to diagnose my problems and get them fixed. This was after two other companies had tried to do this and failed
I would recommend them again to everyone who wanted expertise and high level skills and knowledge who will get the problem resolved.

Steve and Chernet literally saved our kennel dogs and puppies by repairing a heating system that was not designed to function in negative temperatures. They came up with a plan to keep the temperatures warm and monitored them throughout the night!! They did that! And did it all for an extremely fair price. We have had several other HVAC companies come to our business to“fix” our system. Nobody had ever been honest with us, and kept charging more and more each visit leaving us with a system that really was not designed to work properly. We will never use another HVAC company again. Halo has our business for life!!
