Do not use thus company. We endured an awful experience with Summit. In July they installed a new furnace and a.c.. In October we started get "Urgent Service" codes on the thermostat. From October 17 to November 17 they were at our home 2-3 times a week. In our home for 2-10 hours each time. It was disruptive, invasive, frustrating and nothing worked. The Urgent code kept coming back on. Last night - Friday- was the final straw. Summit advertises "EMERGENCY SERVICE". Not true. It you call on Friday they don't return a call until Monday. FALSE ADVERTISING. Saturday morning we called a different company. Within 15 minutes the owner called us back and was able to explain the problem that SUMMIT COULD NOT FIX or explain. SUMMIT advertises false hours. And clearly their staff is NOT up to date on new Lennox technology. We are very disappointed but relieved that a different company was able to help. read more

My heater stopped working on Tuesday and they sent out technician on Wednesday morning! Great service! He fixed the problem right away and it works again! Highly recommended! read more

I hired Summit last year to fix the humidifier system attached to my furnace. They replaced a faulty solenoid valve and the system seemed to work fine all winter. But I recently discovered water on the floor next to my furnace, which is never a good sign. The culprit is the solenoid valve they replaced last year that's now leaking. It's pretty frustrating to spend $380 on a new part that fails within a year and could've caused major water damage to my house. read more

Summit Heating & AC - Leaking part Summit installed - Heating & Air Conditioning/HVAC Near Me - Littleton, Colorado

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! read more

Had a tech come to my house for a ductless AC that wasn't working properly. While the tech was very nice, on time, and had great communication, he horribly misdiagnosed my issue. He told me that my entire unit was blown and I needed to replace my 2 year old ductless unit. He left an hour later and told me the office would be calling to collect payment for the trip charge and give me a quote on a new unit. Thankfully I got a second company out and it was merely a basic leak in my unit. Took the other company all of 20 min to fix it and 3 months later it's still working perfectly. read more

We had Summit install a furnace in our older home. We had received a previous quote from another company but their customer service was lacking so we went with Summit and was extremely pleased. They were on time, efficient, explained everything we needed to come up to code for the city of Denver. Frank and Vincent were amazing to work with and Shane made the pricing process easy and detailed to make an educated decision. Thank you Summit! read more

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! read more

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. read more

Needed an annual service on my furnace. Summit was on-time, courteous, and helpful. The were running a special that kept the costs down. No upcharges or high pressure sales pitch. We'll use them again. read more

Carlos is a great plumber! We always request him from Summit. He is fun to be around and is very knowledgeable. He fixed several mistakes that other plumbers made in our home and suggested and installed improvements to keep our home safe from water damage long term. Thank you Carlos! read more

I have enjoyed great service from Summit on my furnace and A/C for a few years. I have just had a bad experience related to my steam humidifier. The conclusion of the diagnostic visit was that I need to replace the humidifier. I agreed. The estimate that I was provided was $3,150. The Aprilaire 800 humidifier is available from Amazon and other suppliers for $810. The time required for removal and replacement is probably an hour or slightly more. That is $2300 in labor for a 1-hour job. I said that I would purchase a new humidifier and have Summit install it. They refused. Said they do not install customer furnished equipment. I purchased the new humidifier from Amazon for $810 plus tax and hired another HVAC service person who was happy to install the humidifier at a normal hourly rate. Summit's pricing was outrageous! read more

Summit replaced the AC system in my historic two-story brick home this summer. After getting an estimate, the system was installed efficiently and has worked flawlessly. One issue with the installation was the conduit that was run externally for about 10 feet to the GFI outlet. When asked, the electricians came out and re-ran the wire internally. Now, the outlet is right next to the AC unit. I am delighted with the work, as were the city inspectors. read more

I had Summit put in a new furnace & heat pump 4.5 years ago and just in the last couple months, I noticed that the heat pump wasn't working as effectively as it had been. Earlier today, Sky & Tyler (I think that was his name) came out, found a leak in the coils, replaced the coils entirely, and refilled the refrigerant... good as new & all on warranty! Thank you! read more

We had a very challenging installation of a mini split heat pump/AC system in our quad level home. The technicians from Summit were consummate professionals throughout the process. They consulted us at every step with options to reduce noise of operation and disruption of aesthetIcs inside and outside our home. It took longer than expected, but the final results could not have been better. We have a cool, comfortable home that can be adjusted room by room for everyone's preference. We were particularly impressed with the knowledge and professionalism of Amado and Gavin, ask for them to lead the job at your home. read more

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. I found you on Yelp! read more

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! read more

Summit's people are great. We have a multi-level house, which made it difficult to run the AC lines between different areas. Amado and Gavin worked very hard to get our installation right. They are resourceful and determined. Our AC is working and is a big improvement over the swamp cooler we used to use. Cannot recommend these guys highly enough. read more

We were looking for a new HVAC system as our current systems were both getting old and we were not really satisfied with the heating and were looking at adding a whole house humidifier as well. Jeremy came in and did a really in depth study of our house. Turns out our current furnace (120,000 BTU) was too "powerful" for our house and he made recommendations for a smaller more efficient furnace (70,000 BTU) that he was confident would be enough for our house. We were surprised to hear the discrepancy but trusted Jeremy due to his professionalism and the amount of time he took to measure the space of our house and all the windows. The price we were quoted was higher than other quotes we had received but the level of detail from Jeremy definitely demonstrated to us that this was going to be more of a "premium" experience. Our installation date was set up the very next week and Craig and Sal came out and were very considerate about the whole installation process. They warned us when they were going to have to turn off the furnace so we would have time crank up the heat for the few hours we would have to go without. We had a 2 week old baby and a 2 year old toddler in the house and Craig was also very flexible on when they needed to go up to the rooms to install some vents during nap time. He was able to work on other things first before the toddler woke up. He also took the time to explain all the new equipment that was installed. Overall, we have had a great experience with Summit Heating. We are very satisfied with our new HVAC system and also the service we have received both before and after the installation. Would definitely recommend them for anyone looking to install a new system. read more

Bait and switch situation. Called and requested routine cleaning for my AC unit. I do this once a year but my usual guy was unable to come out. Was quoted 99 dollars for the service. The tech came out and did a diagnostic test and a "light cleaning" for the 99. He then told me to clean the coil would cost 180 more and that it wasn't included in the cleaning I requested. I called management to discuss my frustrations of being quoted an additional 180 for the service that I requested when I originally called for. They said it's how they do things and that they would only discount the service 30$ for a cleaning. I ended up being charged 250$ for routine maintenance that other companies charge 150-180 for. Will not be using this company again. read more

We originally contacted Summit in 2017 when our igniter went out on our furnace. It was right before a snow storm and they fixed the issue promptly. We've had them out semi annually since then for furnace and a/c tune ups. We get the same rep (Ben) at each appointment and he is a pleasure to work with. read more

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. read more

Outstanding service. A year ago, they told us we would be needing a new control board. We decided not to replace it at that time and guess what happened when it snowed this week? That's right. No heat! Derek came last night and could not determine the cause of the problem. He was not on call this weekend, but he told me I could call him directly if I was able to recreate the issue. I called him first thing this morning and he came himself and was not satisfied until he knew he had the issue repaired. Sign up for the maintenance plan, you will not regret it! And ask for Derek! Outstanding professional. read more

Summit Heating & AC - Yay! My house is warm again! - Heating & Air Conditioning/HVAC Near Me - Littleton, Colorado

Jake Todd from Summit Heating did a great job servicing my Lennox two-stage/multi zone heating system today. The inducer motor had been making strange noises for several months and I was anticipating an expensive repair. He found the current motor slightly loose causing the odd noise and repaired it by tightening the mounting screws; no replacement needed and no expensive repair. This is a complex system with dozens of wires representing the 5-zones and two stages. Jake jumped right in, knowing exactly where to look, verify the system is working as designed. Great work Jake! read more

MJ has been by far the best technician that I've had the pleasure to do business with in a very long time. In short, my nest unit would not turn on heat. Being in Colorado at this time of year, the last thing you want is snow with no heat (it's supposed to snow today conveniently). He came over right on time and identified the issue really quickly. Now, resolving the immediate issue is the utmost importance. But a close second is maintenance and ensuring the longevity of the furnace. Being that the unit is 10+ years old, we agreed that fine tuning the unit and performing diagnostics was a good idea. He explained everything precisely, and also provided his expertise opinion on what can cause issues in the immediate future (after all, the last thing you want is another breakage after a recent service). In the end, I signed up for a 3 year membership with Summit because 1.) MJ earned my trust and 2.) the membership fee would pay for itself rather quickly. All in all, a very pleasant experience all around. You can bet money that I will ask if MJ can come over again when I need HVAC help again next time. read more

I called and scheduled an appointment based on the strong positive Yelp reviews (and the fact that they respond to every review!). Unfortunately what started as routine call, quickly escalated to an emergency when it seemed my furnace was blowing no/cold air. Summit was great and for a nominal increase they were able to send someone out the same night. Charlie showed up and was awesome. First, simply from a courtesy standpoint, Charlie removed his shoes as it was icy/slushy outside. He took a thorough look at our furnace and thermostat and I was sure based on its age he would simply recommend what I know will be an expensive replacement. Instead he hung out for nearly 30 min trying to replicate what we were experiencing. Naturally it wouldn't cooperate and behaved beautifully during his visit. As his last call of the night he totally could have blown through the call. Instead Charlie took the time to explain a lot about the system including the fact it had a humidifier not in use! He cleaned a sensor and was very thorough with his inspection. In the end, a sensor cleaning and some adjustments to the thermostat settings was all that was done, but so far it's working. Charlie walked through some potential next steps and repairs before we consider replacing. I know when it does need replacing this is the company I'll be calling. read more

Our heater wasn't working properly during one of the days we had tons of snow. I called and left a message and Summit responding promptly within 5 minutes to make an appointment. They quoted me for the afternoon, but if something freed up they would notify me. Summit did find an earlier time and notified me that Cody would be contacting me shortly. Cody contacted me and told me he was in his way. He was very courteous and friendly and found the issue quickly. I would recommend Summit to anyone and use them again if we needed their services. read more

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. read more

Called summit three times and got the answering service the service told me each time that they would have someone call me back and I never did get a call back. Thanks for writing me back Doug and looking into the matter, I know you have all been very busy. You changed my mind and my stars read more

Asked thru Yelp if they could come and service our Tankless water heater. They responded, came out and did so. They provided a discount. They also easily set up a yearly schedule to take care of servicing the Water heater and entire HVAC system. When I put in a new HVAC system 3 years ago, I got 3 bids and they came in second of the 3. Unfortunately the vendor I chose and subsequently installed HVAC and water heater went out of business, (and can't service my HVAC or Water heater) so I thought I would give these guys a try. Very satisfied with professionalism. read more

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. read more

We had good results with the HVAC, so we tried their plumbing. Esteban and Bill replaced my kitchen faucet. They called ahead and showed up on time.They were friendly, professional and efficient. They made great recommendations for the features on the new faucet. Final cost was exactly what they quoted. Very happy with the service. read more

We requested a quote from this company for a whole house humidifier. They came out and NEVER followed up with a quote. I called to inform them I never received a quote I was told we'd receive a call. Another week has gone by and nothing. Doesn't seem like they want business. read more

We woke up at 3AM today in a freezing cold house. The pilot light on our furnace would not stay lit. Called Summit at 7AM and after one ring I was speaking to a live person who said she could send a repairman to our home between 12-2PM today. At 12:06PM the door bell rang and Chris from Summit was there. He found the problem in 15 minutes and replaced the thermocouple in an hour. Heat is back, what a relief. This is a company doing everything right. Wish more were like Summit. Thanks for the timely and expert repair! Sequel: The original repair failed. We called back and this time the owner of the company Bill personally appeared at our home at 7PM to fix the problem. Wow, I am very impressed. Now I know who to call for HVAC issues! read more

Had Summit install a Mitsubishi Hyper Heat mini split unit in a converted single car garage. The experience was great, from working with Jeremy L to figure out the best heating/cooling system and interacting with Sky and Amando as they installed the system itself. The prices were fair and their warranty is solid, but their responsiveness and customer service truly sets Summit apart from the competition. read more

Summit installed a whole house power humidifier for my home. My skin, eyes and throat had been dry in the Colorado winters, so i did some research and decided to give it a try (it is helping a lot). I had a very professional experience with Summit from start to finish. My installer Amato consulted with his bosses to make sure the humidifier was connecting correctly to my thermostat, and Amato even came back after i had already paid to troubleshoot a problem that turned out to be unrelated to his install. Very thorough and mich appreciated! read more

As a former general contractor and project manager, and overall skeptical consumer, I have no patience with subcontractors who try to bs me, or who are just not good at what they do. So I am happy to report that I was very satisfied with the service from Jake with Summit. Showed up on time, didn't fool around, and knew what he was doing. Not like the previous company which was running an $89.00 special and tried to upsell $650 worth of un-needed work. I was happy with Jake's work and think maybe I finally found an HVAC company I can trust. Wouldn't that be nice!! read more

Our baseboard heating system - original to our 60+ year old house - had gotten air in the pipes and was not running smoothly. The Summit boiler technician inspected the system and offered several optional items that he thought would improve its operation, some of which were upgraded parts and some that were maintenance. He explained how and why each step could improve things. We authorized the work, and it was completed within a week. Better yet, it got the system running smoothly again. At no time did we feel any pressure to authorize the work, but we are glad that we did. We'll look to Summit for our HVAC needs from now on. read more

Just now tried to get a simple quote. Instead they tried selling me a safety inspection for $100. I responded back that is not what I was asking for. They wrote be back saying someome had to see the problem before even making a quote. So three issues: 1. Do not advertise on Yelp that someone can get a quote online when that is not true 2. Do not try to sell someone something they clearly were not asking about 3. If you really have to see the issue beforehand, then write back and say that instead of doing number 2 If getting a quote is this shady, I can only imagine how they actually are. Looks like they must of had a lot of their friends and family post positive reviews for them. read more

Our heat was acting funny the last few days so we checked online for a good repair company. Summit is the only one with over four stars on Yelp, which I consider nearly impossible given how negative people can be when posting anonymously. We gave them a ring at 2:30 pm on a Sunday before a snow storm was going to start that evening. They explained clearly the pricing clearly including the $100 diagnostics test. Our repairman Brian called us from his truck at 3 pm to let us know he'd be at our house by 3:30 pm. So for the non-mathletes reading this, that's ONE hour from call to door. Once at our house, Brian quickly identified the issue as a burnt out pump that went a bit haywire due to how our venting was set up when the house was flipped in 2012. Brian had the part in his truck and quickly installed it, as well as doing a tune-up on the furnace, by 4 pm. As for the price, you are sort of at the mercy of companies when your heat goes out before a cold-front comes in, but Brian and Summit explained everything clearly so I could understand it. It wasn't super-cheap ($400), but I didn't feel like I was mugged in my own house or anything like that. Anyway, I'd highly recommend Summit and can't say enough good things about Brian. Good luck with your heating this winter! read more

I left a message and they called me first thing in the morning. This place is run with excellent manners more like a doctor's office than a HVAC place. Ben came out as scheduled and figured out the whole problem with my furnace in a few minutes and had the part to fix it. My furnace is old but he said the rest of it was working fine and we waited to make sure the heat was working properly. I've heard a lot of horror stories about different home service companies. My experience with these guys was terrific. Thanks! read more
