About

Years ago, the founders of Summit Heating and Air Conditioning, Mr. Bill Leech and Dean Peterson, worked at a number of local companies in the Denver Metro area. It was there that they learned the in’s-n-outs of how a typical heating and air conditioning company operates. It didn’t take them very long to realize that nearly every aspect and every division of those companies could be drastically improved upon. There were a number of ideas that Bill and Dean developed that could have helped these other companies serve their customers better. After a significant amount of time and frustration, they decided that if things were going to be done the way they envisioned, they were going to have to do it themselves. Along with the help of some other talented individuals who completely embraced their vision, they made this dream become a reality. This is how Summit Heating & Air Conditioning was born.

  • Chris at Summitt Heating and Air did a great job. He juggled his personal schedule to get our A/C up and running. Very professional. THANKS. James M.

  • Great service! Chris M is very reliable, thorough, and personable. We ask for him every time we need service. M.S.

  • Matt was so accommodating and sweet! He and a few other people had been to our multiple times, as we had multiple issues with our AC. I would HIGHLY recommend this company to anyone!

  • My wife and I just moved into a new home and called Summit to check our furnace and A/C units. Josh came by the house and spent nearly 3 hours thoroughly checking everything. He clearly walked me through everything he was doing, and answered a million questions I had. I'd strongly recommend Josh and the Summit team for any heating and A/C needs. My wife and I will certainly be going back to them in the future.

    Jeremy B.
  • Definitely recommend! Everything was very professional - from the first call and the lady that answered the phone to the e-mail confirmation and phone call of the technician 30 minutes out. Chris was super nice and knowledgeable and fixed the furnace quickly and without any issues.

    Kelly Z.
  • Wonderful people. Everyone we have been in contact with is polite and knowledgeable. And they always answer the phone. We won’t go to anyone else.
    I found them randomly some time ago when my children were in diapers. The A/C went out, and my house was 95 degrees. They came over and did everything they could to fix my lousy condenser. Never pressured me to get as new one, though they weren’t certain how long it would last. They ended up fixing it...even ran home to get a part.
    It is a good feeling to be able to trust a company.

  • First time using this company. Off normal hours, Chris was on premise in a very short notice. Extremely professional and courteous. This will be my go to company for heating/ac needs ! ! HIGHLY recommend !

  • Great work done by the team on short notice. Sal, Craig, and Mitch did nice work.

  • Brian, Tanner, and Jamaal were awesome! Brian had a great knowledge of HVAC systems (particularly mini-splits) and he figured out a great solution of how to install it in our 100+ year old home. Tanner and Jamaal were quick with the install, insightful by describing what they were doing, and were thorough with their work. All 3 were super friendly and were very aware of social distancing by wearing masks and shoe covers any time they came in our home. Great experience all around!

    Nate B.
  • Craig and Sal were great. Very professional, answered all of my questions. Highly recommend !!!

  • Joe serviced our swamp cooler and was efficient, professional, and so friendly! We really enjoyed working with him and will continue to use Summit Heating and A/C.

    Sarah R.
  • Such a GREAT experience! Ben called and asked if he could come early. He was polite, he looked very professional and if I owned a business he would be the standard. No face tats or gauged ears or garbage like that. He did his job quickly and efficiently, he identified the problem and corrected it and he was done in a half an hour. Because he was able to get to me before the end of regular business hours I got charged the regular hour rate which was about 40$ cheaper AND the service was already 50$ cheaper then the competitors.
    Well done Ben your a credit to your company
    Thank you.

  • I've been working with Summit for over 2 years now. Overall, while the work that they do is good, my 5-star review is because of the trust that they have earned by being committed to doing what is right.
    They started with a small job to try and resolve our issue, and then had to do more. Their founders were at our house several times (at no charge) to try and understand the problem. I also trusted that they would get it done right. Their crew spent days at our house making sure the work was done right and in a way that completely minimized the impact to our home's aesthetics.

    David L.
  • Easy to schedule and very prompt. MJ did a great job in addressing some of the issues that our furnace was having, and keeping us up in the loop about what was needed to be done. He was able to fix our issue the same day.

  • Summit Heating and Cooling is the real deal. I received an email back in 6 minutes on Christmas Day. I was scheduled for 9 a.m. the next morning and Josh had my furnace repaired in 20 minutes. Excellent first impression and I have a new HVAC company!

    Jay B.
  • I've used Summit Heating & AC twice this year, for furnace and AC repair. I'm very satisfied with this company. Their communication is excellent, their customer service is top-notch.
    Charlie came by to check on our AC and help identify some trouble we were having with it. He was very patient and courteous, taking the time to explain the situation to both my wife and me and answer our questions. While I'm sure he had a long line of other customers to get to, while he was here he took his time and treated us like we were his only job for the day.
    The outstanding customer service provided by Summit is why they are the only HVAC company in my contacts list.

    Brian A.
  • We've been using Summit to service our A/C for 3+ years now, and have been so happy with their work every time, whether its emergency repair or routine maintenance. Every service person we've encountered is friendly, punctual and only recommends what's necessary, and always feel the pricing is fair. This is a GREAT local, family-owned business and we're thrilled to give them our business.

  • 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!

  • Called these folks for a quote on getting Central AC installed. Extremely responsive, quick call back. The main office scheduled a specialist to put a quote together. The guy did a great job -- explained what I needed to hear and see. He helped explained my existing furnace, the existing ducts and what the options were to retrofit in Central AC. Summit had installers come out repair my existing furnace THAT DAY, and the fixed it in under 1 hour. They were ready to go with AC install as soon as the NEXT DAY. The installers Craig and Sal were extremely quick, thoughtful, and respectful of our property and space, they brought in their own electrician, and I had to plan for nothing. AC was installed in 1 day, it looks very professional, it works great, and most importantly the wife is very happy. I would recommend this to company to anyone looking for experts to help.

    Paul B.
  • Thank you to the Summit team. We had to replace both the AC unit and furnace. Everyone was friendly, helpful, and knowledgeable. Craig and Sal showed up right on time for the install. They were respectful of the property and friendly. They went above and beyond to make sure the job was done correctly. Even though working on a 90+ year old house never goes as planned, they took the extra time to do it right. Thanks Craig and Sal! You guys are awesome.

    Amy N.
  • AC was on the blitz. Got a quick appointment and system was fixed in less than 90 minutes! Great rates and gave me several options for repair. These are very trustworthy people and Benjamin was incredibly knowledgeable and professional. I will only call this company in the future for all of my HVAC needs!

  • Rarely do I leave a 5 star review for a service company, but I think I've found it. If you're in the Denver area I can attest to the great service provided by Summit Heating and A/C. Our heater broke over night and we woke up cold. Summit sent out one of those reps before the work day was over. Josh was a great representation of a qualified, knowledgeable, and friendly service tech. Although the fix wasn't as cumbersome as I had feared, Josh walked me through how to do a little TLC myself to prevent future similar issues.
    In my experience, this outfit is second to none in the area. Give them a try, you'll feel all warm and fuzzy...or at least warm again.

    Dan W.
  • I have never had a company spend more time with me finding out my needs and figuring out what would work for my house. We recently replaced our heater and had A/C installed and I couldn't be happier with the service and quality of work. I highly recommend this company!

  • I’ve got a rental home in Littleton, CO and I decided to use Summit Heating & Air Conditioning to replace my old air conditioning system. After finding the company on Google maps, I stopped by to take a look at some of their showroom systems. It turns out they are completely rebuilding this gorgeous new location to include a trading facility and the showroom was not ready yet, but they still took the time to give me a tour and I thought the company was so professional and genuine that I decided to purchase a Lennox system on the spot. With the sunrise and how their team prepares before they head out to homes, I felt like I had to take some pictures so I attached them. What a nice and friendly company. Everyone had their shirts tucked in greeting me with smiles saying good morning and everything. I wish all companies treat people this way. I plan to call them if I ever need any repairs now as well!

    Michael V.
  • I initially called Summit to come out and do a repair to my furnace. Since then, they have been out a couple times for other repairs. Every single time their office staff and techs have been top notch and professional.
    I have since purchased a new furnace and AC system after the home and garden show. Pricing and home evaluation was straightforward and honest. Many financing options available.
    Install day was a terrible snow storm but the techs came out and protected our floors replaced the old system and shoveled a path to the backyard to get the AC unit set. Jake and his helper did their best in a bad situation. After the install I had some concerns that you could see after the snow melt. Again, Jake, came back and went above and beyond.
    I probably won't see them again unless I need a tune up.
    Put your wallets down and consider what great service and warranty work is worth to you. I would recommend Summit to anyone I talk to, neighbor or contractor.

  • We were without heat, and because we have a more complicated heating system than a typical furnace we had multiple companies out that provided incorrect assessments of the problem, until Josh from Summit came out. He quickly identified the issue given his extensive knowledge, and fixed the problem. When we had another problem that was unrelated, he came out the same day as we called, quickly identified that and resolved it too.

    Jim M.
  • Our heater failed on Saturday night and Sunmit came out on Sunday to fix it. Josh was super helpful and kind in getting us all setup. His coworker even came over on his day off to bring a needed part so we would have heat that night. They really went above and beyond.

    Allen C.
  • The morning started out without heat. Called Summit and was quickly scheduled for a tech to come out. He arrived earlier than we expected which was absolutely fine. It took awhile to identify the cause, get the part and get things running again. Josh fixed things up professionally and with dispatch. Very much appreciated. William W.

  • We needed a full replacement of our AC unit and after meeting with Jeremy decided to also upgrade our furnace in the process. I can not recommend this company enough! Craig and Sal were our installation techs and were absolutely wonderful - careful, friendly, respectful and even made friends with our crazy dog!
    Love that they are a small, family owned business and how great the whole team was during our initial consultation and installation. They were prompt and all around would highly recommend them for your heating and cooling needs!

    Caitlin G.
  • I had central air and a new furnace installed.
    Brian came out twice and did a very comprehensive evaluation of my property in order to give an accurate quote.
    Craig and Sal completed the installation. They were knowledgable, punctual, and super nice guys. They left my house cleaner than it was when they arrived!
    I received three quotes before I chose Summit. I feel that I made the right choice.

    Jerry D.
  • Overall very impressed by Summit Heating & AC. Jeremy explained various options for us, gave a competitive price, and set us up. Craig and Sal spent a full day installing a Daikin minisplit for us and did an excellent job. The look both outside and inside is clean and sleek (slim profile). They were very professional, hard workers, answered all my questions, and got the job done with no complaints. My office is now MUCH cooler, no longer need to work in the basement in the summer. Highly recommend!

    Matt M.
  • Chris is the man! I'm the least handy person and he was able to walk me through the problem and the solution with ease. I know more about my home and my problem is solved.
    I thought the reviews for summit might be too good to be true, but I couldn't be happier.
    Thank you Chris!

    Ben Y.
  • Great support. Josh came out and provided a nice evaluation and spelled out options and costs for a whole house humidifier. He then scheduled the install right on the spot. Christopher (Topher) came out on time for the install and both fast and clean and efficient. He took time to clean up all the runs and the setup looked better after he got done than before he got started. Topher then took the time to walk us through the daily operations and periodic maintenance needs.
    Great experience!

    Rick K.
  • We needed a new A/C unit for the house. Craig and Sal were the technicians who performed the installation. They arrived on time, were very professional and friendly, explained everything upon completion. We are very happy with their service.

    Tatyana T.
  • Five star service!
    Summit was very professional when I scheduled over the phone, let me know what to expect, and when my technician Brian showed up, he was very efficient and did a great job.
    Summit gave me a 2 hour window for my service technician's arrival when I scheduled, which is much better than the 4 hour window I have experienced at other places. Brian gave me a courtesy call when he was on his way to my place and let me know what time to expect him. When Brian arrived, he was friendly, educated me on what to expect and what services he would recommend in the future, and finished up much earlier than I expected him to. The whole process took under 2 hours.
    I would definitely recommend Summit! As a plus, if you commit to yearly maintenance for a minimum of 3 years, you get a 40% discount on your future yearly maintenance services!

  • We had an attic furnace replaced and A/C installed along with all upstairs ducting replaced. I worked with Brian Carroll, Jake and Shane and all were professional and courteous. Communication was clear and their attention to detail was appreciated. They were respectful of noise while we were at home and on calls and completed the install in the time that was estimated. The system works great, the experience was non-invasive and I would recommend that particular team and Summit Heating & A/C as a company overall to anyone looking for high quality service. We'll use them for anything HVAC related in our home from now on. Graham G.

  • Summit has worked with us through all of our AC issues, they have excellent staff and really do have your best interest in mind. They replaced our AC last year and it worked perfectly through the hot summer!!!! Thanks Guys!!! JH

  • Preventative maintenance is my M.O. Had my annual a/c and furnace serviced. Nothing but happy with this company. Always on time and thorough. Josh performed a quick check up and also performed a hot water heater quote.

    Larson C.
  • They showed up on time and where wearing masks. The installation crew completed the job quickly and efficiently. The quality of the workmanship was spot on.

    Bill T.
  • Okay, I won't say buying a new furnace is painless - after all, there is the cost. But for value and ease and great service, this was tops.
    Josh did the initial inspection, told us why we needed a new furnace, and added that if we bought from Summit his inspection and tune-up fee would be rebated. He didn't push us. His explanation made sense. Okay, on to the next step!
    Jeremy examined our current setup and told us everything we would need right down to the penny. He explained everything thoroughly without wasting time. Thank you, Jeremy, great job. You made being "sold to" as painless as possible.
    Just a few days later, Topher and Mike came to install our new furnace and the accompanying thermostat. In by 8:30, out by 4:30. They fixed everything, including things that we didn't know were wrong. Everyone from Summit was friendly, fast, efficient, thorough, and concerned with our lasting comfort and safety. You can't beat that.
    We also had to have a lot of electrical work done. Summit provided "their" electricians (Vossen) and included the electrical costs so we didn't have to mess with any details. Down to the penny, guaranteed. We knew we had to get electrical work, and it was so nice not to have to search for it or worry about it.
    Great work, Summit. You deserve all those 5-star reviews.

    Robin M.
  • This review is way overdue since we have used Summit Heating for 3 years now. These guys are great! They are fairly priced, very responsive, easy to schedule, and have great people working for them. Highly recommended.

    Ianina S.
  • Summit Heating and AC have been great from the first contact. Brian came and did the site survey, giving me an understandable walkthrough of my options and a quick turnaround on the estimate. I didn't feel any pressure to buy and I was given plenty of options.
    Today Topher and Sal installed the system and I couldn't be happier. They were extremely professional and friendly throughout, did a great job with the installation and in explaining the system fully. I wouldn't hesitate to recommend this company to anyone.

    Matt W.
  • We hired Summit for a full level system install in an old Denver home. Jake and Shane were very professional and did their best to minimize the mess during the plaster cutting. Jake kept us apprised of progress daily and when complete gave us a full tutorial on how to use the in attic and ductless combination system. We are very happy!! Heather in Denver.

    Heather M.
  • Thank you for making things right!!! I appreciate you all coming back out to fix the leak!!!
    Horrible! They do not stand behind their work. If you want to pay a lot of money, have the cost grow as the project continues and then still have a system that doesn't work and leaks call them! Their first visit I paid to fully replace the motor of the swamp cooler over $1,000, then the system still didn't work and he returned to update pads for another over $400!!!! And a few weeks later I returned to see a steady flow of water leaking out over the roof!!! When I called to see if they would stand by their work I was told only if a technician says it is related to their work, otherwise it's a $175 trip fee!!! How could it not be related to their work, the swamp cooler never leaked before!

  • For the third year in a row, Summit doesn't disappoint! Their service people are pleasant and polite and get the job done right. Jose Hernandez did a great job today and we really appreciate his service.

  • I found Summit a year or two ago to do my annual furnace maintenance. The whole experience in terms of scheduling to arrival was great. So when they told me they had a club type program you could join and get yearly reminders and some discounts on service, I was onboard. I have two furnace and two A/C units, so every little bit of savings helps. Fast forward to this past weekend, and my main level A/C stopped working just as family had arrived in town. After troubleshooting the situation, I gave Summit a call, and they were able to get someone out that same day (Sunday). The technician Rich showed up with a mask and got to work on the problem. Turns out there was an electrical short in the unit, which ultimately also fried my thermostat. While he was out, he also discovered my humidifier (which had been added by another company) was wired improperly. All in all, in the course of maybe an hour and a half he fixed three separate things.
    While it's never thrilling to have to pay for repairs, I appreciate the transparency Summit has with regards to pricing both when scheduling and during the visit. And that club membership did manage to save me about $50-60 on the whole. It's nice to have a go-to when it comes to house issues, and I feel like my HVAC is in good hands with Summit.

  • Summit Heating & A/C did a great job on my air conditioner install in August, 2020. Josh came out to examine my original-to-the-house a/c of 26 years. I knew it was on its last legs, and he gave me some good advice to not fix it and throw away good money, when the unit was so old, it would need to be replaced shortly, anyway. On the day of install, Craig & Ray did a fabulous job. They arrived at like 8:30am and worked tirelessly until 4pm. They cleaned up everything and didn't leave me any mess or parts to dispose of myself, and they even fixed the crooked ductwork that was installed with my furnace replacement 8 years ago. Craig & Ray were not only clean and efficient, they were not loud (as I'm stuck working at home due to COVID). Totally recommend Summit, and I signed up for the regular service plan. I finally have found my permanent HVAC company! Thank you, Summit!

  • Wife and I decided on this company for our annual tune-ups when we purchased our home in 2017 based on good reviews across all platforms. Our systems at the time were 30+ years old, and on their last leg. We were anticipating some work in the future where we'd be adding on space to the home so were really trying to defer major AC work until that time.
    Fast forward 3 years and not only did these guys/gals keep our old systems "alive" for the past few years, but we used them as well for a brand new furnace/AC install including humidifier and reme unit. We did run into a hiccup with the reme/humidifier install, but JT (regional mgr) came out to visit to see what options we had. He came up with a solution that worked for all involved, and had a second crew out to finish it all up.
    I can't say enough good things about how this company operates. They communicate, follow thru when there are hiccups along the way, and most importantly make sure all parties are happy. Special shout out for the install crew, Jake and Shane who came back out today to tie it all up. As long as Jake/JT/Shane are with this company, they'll have my business.
    P.S. - virtual high five for them taking COVID seriously too, and generally being cognizant of you the homeowner's home. They wore masks every time they were here, and wore booties when entering the house. Especially comforting now more than ever with a pregnant wife during these crazy times we find ourselves in.
    Thanks again Summit, and Jake, JT, and Shane!
