Hiya, just a note to rave about Summit’s technician: Steve Watts. He is a perfectionist: utterly thorough and meticulous. Cares about home-owners’ safety. Super nice guy and very professional. We’ve been through many Breezair service companies and none have matched the expertise that Steve provided. Because of him, I’d recommend Summit highly!!! We’re very fortunate to have found Summit and Steve in particular! - Tia G.

Great service. Effective Air Conditioning cleaning and repair service Friendly dialog and helpful advice. - Judd W.

Had the awkward experience of waking up to a cold house. Furnace was off on failover. Called and was able to get same day support from Summit when others were quoting 2-3 days. Chris the technician was professional , had all the proper diagnosis tools- and identified a faulty igniter in 15 mins. Replaced parts and was out in less than 1 hour. - T. R.

Josh and Bill worked over the weekend to change out my furnace and A/C. The work was second to none! They started at 8 am and was done by noon! I can’t recommend this company enough! - Richard Smith

We are thrilled with the service and quality of work Summit gave us with our furnace and hot water install. Our dual furnace was almost 26-years old when one of the units stopped working, and with changes to code over the past two decades, our service team (Tanner and Robbie) had a good amount of work to do to bring it up to code, in addition to simply installing the units. Tanner and Robbie were polite, wore masks 100% of the time, and kept us informed every step of the way. We have used other heating companies to do repairs in the past with average results/service. We recommend Summit highly to anyone needing a new furnace or water heater. - Christina S.

I just wanted to thank Josh and your company for providing prompt and excellent service! We woke up yesterday to no heat and no hot water. We have a boiler system and from past experience not every HVAC company works on them. I now had a difficult decision to make on whom to call. We didn’t have a regular HVAC co to service our boiler. I was going to have to make a cold call and try a new co out. I actually had made a different appt with a different company that was in our area to come out today to work on our boiler. After running several errands yesterday, I checked my phone for messages, I had a message on my phone that the HVAC company was going to have to reschedule my appt. I called them at 6:05 pm and their offices were closed. The recording stated that their holiday office hrs were closed Christmas Eve and Christmas Day and Saturday the 26th was their first open day for a possible repair. I was desperate, we had no heat and no hot water. The thought we may not have anyone be able to repair this for us with the holidays upon us I started searching for another HVAC company. What honestly drew me to Summit was that at 6:20, I was actually speaking to a live person that was able to schedule an appt for today between 7:00 and 9:00 am. In fact, their website states they are open until 9:00 pm! Josh showed up promptly, assessed the problem, picked up the parts, installed them and tested the system and was done before 9:30 am. Thanks to your whole team, our boiler is up and running. Great customer service from your receptionist to your repair team! I couldn’t be more grateful. Well done! - Mary K.

We decided it was time to replace our 30 year old furnace a few weeks ago and reached out to 6 companies in the Denver area for quotes. Brian with Summit was the only one of the six that took the time to evaluate our heating and cooling needs. All the other companies were just going to replace the already oversized system with something even larger. We were on the fence when it came to replacing the old AC at the same time, but ultimately decided to do the whole system at once since we would likely be needing an AC replacement in the next couple of years anyway. Brian laid out our options, explained the work, set expectations for the duration and gave us an upfront, all-inclusive price. Summit was not the cheapest (or most expensive), but we had been down the low-bidder path on a system at another house and after the other company added up everything they “ended up needing to do” they were actually higher in the end. As for the install, we couldn’t have been happier having Chris and Sal in our home. They were professional, knowledgeable, thorough, timely and respectful. We truly appreciate the time they took to do the job right the first time. Bottom line…If you have been down the road of a full system replacement in the past you know how important a professional, permitted installation is to the life of the system. If you have not, don’t find out the hard way! Start to finish the team at Summit hit all the marks earning another FIVE STAR review! - Jarrod S.

Unfortunately, my 22 year old furnace died a month ago and Summit replaced it with a new one. I got quotes from three places and Summit was the most expensive (by a little bit) but they also had the best warranty so I went with them. I thought everyone I interacted with was professional and knowledgeable. They also installed it on a Saturday which was convenient for me. Would use them again! - Brian C.

This company has been fantastic. They have serviced our old furnace and AC for years. Ben was our technician for a couple times and he was always honest. He told us eventually we’d need a new furnace and AC. That’s where Donnie comes in for an estimate. From the beginning when Donnie gave us a quote for a furnace and AC, he was knowledgeable and professional. Then the crew came over and were just as great! Tanner and Robbie were here on time and finished the job sooner than expected. Both of them respected our home and wore masks the whole time. Cleaned up when needed and were very communicative. I highly recommend this company. They provide excellent products and customer service. - Mara S.
