3 Best HVAC Services in Thornton, CO

Had Nate out to do a service/panel upgrade and add a new subpanel. Zero complaints -- he did a great job and got it done in one day while my family was out of the house. Had Kappler back out for a Mitsubishi ducted heat pump install (replacing an old furnace/AC). The entire crew was friendly and worked diligently to get things installed in a timely manner and the heat back on by end of day. Unfortunately, an issue arose during install that I was not happy with -- when time permitted, I reached out to the install manager (Justin) and after discussion it was decided that Kappler would replace the outdoor condenser unit to resolve any issues beyond a shadow of a doubt (at no cost to me). They came out today and performed that replacement with no issue. I think it very likely that many contractors would have brushed aside my concerns. In my view, it is more important how a contractor handles problems/unhappy customers than how they handle things that go perfectly as planned. (After all, in my experience, it is rare that work ever goes as planned...) And Kappler took the "100 % customer satisfaction" thing very seriously which I sincerely appreciate.

Excellent installation of a new HVAC system, thousands below another highly rated competitor. They went out of their way to do a clean installation without even removing any drywall, which was a pleasant surprise. Courteous, friendly, and knowledgeable team. Highly recommend.

Was looking for a company to install a heat pump. Their estimate was prompt, the price was fair and the installation was done in one day. They submitted the paperwork for the rebate and the warranty. Everything was handled quickly and professionally. I’m very happy with my decision to use Kappler Mechanical.

Excellent service. Chris actually showed up before scheduled appointment, which is rare and quite pleasing and refreshing considering that most appointments scheduled with a two hour window, by other companies, are started the last minutes of the last hour in the two hour window. Chris was pleasant and professional. Again, excellent customer service.

Great service by Eric Ward and Impact Heating and Cooling. This is the 3rd year that we have used them to service our HVAC heating and cooling. I highly recommend them. I just learned today that they also have plumbing and boiler service and intend on calling them in the future. Real honest people!

Great, efficient and reasonable service as usual from Impact Heating and Cooling and Electrical. I know I can always count on their techs (today it was Aaron Lind) to do excellent work.
