They've been maintaining my old system for 10 years, so I have a lot of confidence in them. Before the installation I had many detailed discussions with Phil, the owner, about the specs for the job and what specific equipment to install (there are lots of choices in this kind of system). Phil always listened to my concerns and explained everything very well; he is low-key and did not pressure me to buy anything in particular. One of the difficulties of the installation was that we did not have any specs for the old system and had to guess as what the capacity of the ground loop is. Installation was done on schedule, over a period of five days, by Aaron, Frank, and Zach, and they did very careful and neat work. The resulting collection of pipes and boxes is beautiful (if you like this kind of thing, and I do). I especially appreciate that they cleaned everything thoroughly when they finished. The new system is working much better than the old one, especially for cooling and for air flow.

Best in industry -- team, installation and product…read more I was looking for a team that really knew their stuff and cared about each project as if it were in their own home. With that in mind, the team at Sensible exceeded my expectations. I selected a mid-range, 2 stage heat, 2 stage AC, Bryant system; comparing other top-rated brands and their associated, local installers. The Sales Pro did more to earn my trust than the competition, and a Carrier brand looked/sounded good after weeks of product analysis on the web, talking to neighbors and friends...mulling it over. When installation day came, two professionals with extensive industry knowledge, decades of experience, standout courtesy and unusual attention to detail, installed/retrofitted the new Bryant system in our 23 year old home. The Ops Manager came himself to ensure a timely delivery during a hot summer -- hot for Denver at least. They ensured my very clean home stayed very clean and left the HVAC closet and plumbing in top shape. I am picky, fastidious, politely called "detail-oriented". Turns out these guys are equally picky. I researched for days before selecting the Bryant brand and Sensible. I feel fortunate. I hit the jackpot for HVAC professionals.

The short story: Not to be trusted. Just another contract service provider taking your money for…read moreunacceptable, low-quality work. The long story: I had a technician come out to service our swamp cooler for the summer in May. We hadn't used the swamp cooler at all because we were new homeowners. We bought this house in November, and needed help getting it primed for this Spring and Summer. We knew before buying the house that the swamp cooler was not maintained - but all we thought was that it had rusted and needed new pads, according to our inspection. (The previous owners said it was a relatively new system....it sure didn't look that way.) When I booked the service with Coyote HVAC, I requested a swamp cooler deep clean in addition to the seasonal start-up service, which they agreed to. The swamp cooler was full of rust and we didn't want to attempt to clean it ourselves. A few weeks after their visit, I realized that 1 of 2 vents in the house was not blowing any air whatsoever. (It took me a few weeks to notice because that vent is in-between the dining room and kitchen - not somewhere we constantly occupy or notice direct air hitting us.) Then I remembered that Coyote HVAC ALSO never tested the vents to make sure they were working after they supposedly got our swamp cooler up and running for the season. Anyways - 3 days days ago, the swamp cooler stopped working altogether. When I called Coyote to book another appointment (which I would have paid for), I was told that I am now out of their service area since they merged with a different HVAC company. So we scheduled a different HVAC company who came by yesterday. They reported that every part in the swamp cooler was busted, aside from the pads and the belt. The motor is fried. Only 1 of 8 distribution tubes is working. And, the inside is still completely rusted and looks the same as the photos from when we bought the house. There was no deep clean when the Coyote tech was here. In fact, I am not sure if he did anything at all, aside from tell us that it was "good to go". after spending about 20 minutes on the roof with it. Before leaving, he asked if we wanted to schedule an appointment to learn about heat pumps and a potential system upgrade at some point down the road. I agreed, thinking we would schedule an appointment a different day or the following week, but he immediately called a colleague to come over the same day and give us a $20k estimate for a new heat pump/AC system. Again, the first tech didn't mention ANYTHING about our current swamp cooler being on the verge of complete collapse. We weren't looking to install a brand new AC system, but they were sure quick to try and acquire our money for one. We knew the swamp cooler was NOT in good shape when Coyote HVAC came to prep it for summer. However, the issues that a different HVAC company discovered yesterday (like 7 out of 8 distribution tubes not working) and signs of system distress would have been obvious in May when the Coyote tech was here. I should have asked the technician for photos after he "cleaned" and serviced the cooler. Instead, I made the mistake of trusting Coyote HVAC to do what I paid them to do. How silly of me. Thanks for nothing.

In 2013, I purchased a townhome in need of total renovation. The inspector pointed out that the…read moresump pump needed replacement and the furnace may need to be replaced in the near future. After a year of dealing with a noisy furnace that was unable to heat my townhome adequately and an inadequate central air conditioning system I decided to get estimates on replacing the furnace and sump pump, cleaning the a/c compressor, draining the hot water tank and placing a pan underneath which was also recommended by the inspector. My employer highly recommended Quinnair so they were the first company to evaluate my jobs and give an estimate. Another company would only give an estimate on the furnace and sump pump and the third company would only give an estimate on the furnace. I decided to hire Quinnair, not only were they thorough, they included several additional services with their estimate along with a much better furnace (97.3% efficient) than the other companies who offered an 80% efficient furnace. Their Better Business Bureau and Angie's List ratings were much better than the other company's ratings. The afternoon before the furnace was scheduled to be installed, I had set my central air conditioner at 77 degrees and at that time the interior temperature was 78. I left for a few hours and when I returned the interior temperature had increased to 81. I had hoped that a thorough cleaning would solve this issue but when the representative arrived the following day, he examined it and found that the compressor was fried and it was inadequate for the size of my home. I had to make a decision quickly and if it wasn't for the representative's knowledge of current financing offers, I couldn't have afforded it. With that said, Quinnair came in under the third company I interviewed who was only going to replace the furnace with an 80% unit. The installers were professional and stayed until 8 PM on the second day in order to finish the air conditioner installation and 7 PM to finish the jobs on the third day. All the jobs were completed in a timely manner and I can sense a huge improvement. I am very pleased with this company and their dedication to their customers and the local community. I intend to hire Quinnair when I need to replace my water heater.

Extremely disappointing experience, absolutely avoid!!! If…read moreyou want to be completely disrespected as a woman, spoken to in a deeply condescending manner, and treated as if you couldn't possibly understand basic technical issues, then this is the company for you. They charged us for an inspection that was clearly not done properly, pushed us to replace perfectly functional parts at nearly 10 times the market price, and literally laughed in my face while telling me my HVAC system was "shitty" and needed to be replaced. Three days later, the system had another issue because they completely failed to identify the actual problem. We were then pushed yet again toward more interventions and more part replacements by a manager who had never even seen the HVAC system himself and could only give vague explanations about what the issue "could" be. When I later requested my file, pictures, and full documentation from the visit, nothing was ever sent. No transparency whatsoever. We finally contacted another amazing company ALTITUD BRO HVAC-- which I strongly recommend -- and unlike UHCPC, they actually inspected everything properly. They identified the issue immediately and charged us only $400 for something that probably would have cost us over $2,000 with UHCPC. What a joke. And the funniest part? They're apparently just as bad with plumbing. We worked with them in the past on another property and, after charging us over $20,000, not only were they unable to properly fix the issues, but they also damaged one of our showers. Matt Robledo, the owner, even told us he had to fire his plumber Dave because "he was not good" and promised us compensation or future repair credits. Of course, none of that ever happened. Once they take your money, they seem to forget your name very quickly.
