I had a completely new AC system installed. 1. I had five different vendors evalute and give me pricing. The ranged from one person saying they could do it over the phone (really?). And then there the utlimate professionals, Summit Heating. Before they gave pricing Jeremy visited our house for two entire days to make sure he had the correct system and specs. He even had the manufacturer rep come to the house to consult on the job as well. 2. Professionals - Soup to Nuts Quality It took one week to do the install but during that time they were the consummate professionals always cleaning after the workspace and doing high quality work. They handled all of the permits so we didn't have to deal with it. 3. Stand by their work During the job they broke a mirror and our doorbell. It's an old house and that type of thing is expected. (Things happen!) They gladly offered to credit the amount of each on our bill. They took accountability and made it right. Bottom Line: These guys aren't the cheapest in town, but they will do the job right and ensure you have a great AC system in the end. read more

Excellent company!!! It is hard to find an HVAC company that is trustworthy and committed to doing a good job. Everything from the receptionist who booked the appointment to our awesome technician, Josh, was excellent. Josh has a lot of pride in his work. I will use this company again!!! Reasonable prices, too!!! read more

I sent in a request for a quote at 2:30 this afternoon, the website said 100% getting back in 1 hour, it's now 5 and I still haven't heard from them. FALSE ADVERTISING read more

Our heat went out at our house yesterday and I was able to get someone to repair it today. I haven't had a furnace repaired s before, but the prices seemed very high for my taste. Perhaps it was my fault for learning the prices of certain parts before calling - note to others, don't do that. That aside, Preston was great. He was courteous and patient as he talked me through my sticker shock (a good spiel as I am sure they get that frequently). Most importantly, he got the heat working. (Preston gets five stars) I am giving three stars because when I called to set up the appointment I asked how much charges usually run and the individual I spoke to would not give me a quote on how much certain average or common repairs might be. However, the technician informed me that all repairs are essentially flat rate and prepackaged. So the individual who booked my appointment could have said "to fix the ignitor, our package costs ----" and "to fix the flame sensor our service costs ----". Had I known that I could have been a more informed customer and been able to make a more informed decision. I also did not love that they have their technicians push a "membership" on their customers. At least for me, it was difficult to understand as I was trying to process sticker shock combined with no heat. But, they got the heat working and they showed up the same day I called them. read more

Charlie came out to winterize our EvapCooler and tune our furnace. He arrived within the time window specified, worked quickly and carefully, and communicated clearly about items that needed acknowledgment and follow up. Additionally, relevant notes and photos were taken and shared via email at the end of the visit. If you want a friendly and professional service technician look no further than Summit Heating & A/C. read more

Great company. Technician Charlie was very professional. He took time to explain our system and its various issues and answered all of our questions. Scheduling process was easy. Tech came at scheduled time with a call 30 minutes prior with his e.t.a. There weren't any unnecessary upsells or additional fees, and the final bill matched the what the office reps said we could expect for charges. Will gladly use Summit again. read more

We had a great experience with Summit -- they assessed our broken furnace, and replaced it in a very timely and professional manner. Honest business and everyone we worked with was communicative. Would highly recommend read more

After dealing with another company for the last few days to get an appointment to have someone come check our furnace we finally called Summit! They were able to come out same day (on a Sunday) and fixed a bad sensor on the furnace. Benjamin was very professional and did a great job! We will definitely use Summit in the future! read more

First I posted this rating because of inefficient and frustrating scheduling. I requested an available time, did not hear back for days (not 20 minutes), and was finally offered a completely different time after hours with an additional fee. No other options. Then I changed this review because the owner reached out to me to tell me how wonderful and hardworking his team is. That may be true, but they didn't work for me. Perhaps if instead you had reached out with a timely booking without extra charges I would have had the opportunity to rate your actual services, not just your customer service. read more

I've lived in Colorado for 3 years and this was the single best experience I've had with a contractor since moving here. Jeremy, Erin, and Daniel were awesome! Jeremy did a great job walking me through the process and putting together a competitive offer, he wasn't pushy and was a great consultant. Erin and Daniel were so cool - my dogs even loved them! I really appreciate how they made a fairly invasive 2-day project as simple as possible for me. They communicated timelines, progress, and confirmed every hole before drilling. They also cleaned up after themselves and put in a ton of effort to move carefully through our house and yard. Plus, they were awesome with our 2 crazy dogs, which makes having "strangers" in the house so much easier! read more

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. read more

Hired Summit to install mini-splits in my house to take advantage of the Denver climate rebate and Xcel's rebate. They were amazing from start to finish. Never felt like there was any hidden stuff, everything was upfront. Workers were great and the work they did was fantastic. Summit stands behind their work and were a pleasure to deal with, and my new units are such a great upgrade over my old system! Highly recommend Summit! read more

We had a leak occur and within minutes Carlos was able to diagnose our problem and then gave us a very inexpensive solution. He was extremely knowledgeable and helpful about other problems we were having. We will be calling again as soon as we need help! Strongly recommend for reliability and cost. read more

This company restored my faith in customer service! We called them when our A/C would not run ( and it was brand new-installed by our builder) for Denver's first real hot spell this year. They were able to come service our unit the very next morning. Their receptionist was very helpful and polite. Charlie, their technician came to our house the next day at the earlier segment of our two hour window too. He was very courteous and efficient. He quickly showed us that he was very knowledgable and explained everything clearly to us. He WAS able to get our A/C running and corrected the problems we had. We joined their club membership (members will get service discounts) as we plan to call THIS company whenever we have need for Heating or A/C service in the future. What a fantastic company! read more

We have gone through a number of HVAC companies in 17 yrs we owned this home. The original installer would not come back for service calls unless we had a service contract. The next company had good service, but told us the last time we needed service,they were scheduling 3 weeks out . The next company came out and did the minimum but I was not impressed. I came upon the great reviews for Summit on Yelp and thought I would give them a try. I called on a Friday and Jake came out on Monday, evaluated our furnace, diagnosed the problem and made recommendations on what we should do. Although replacing the high limit switch would have (and did) correct the problem, Jake also made note that the blower motor was pulling more amps than expected and recommended it might be good to swap at the blower motor while they were replacing the switch. Although I was tempted to delay on replacing the motor, I decided to follow his advice and I'm glad I did. When he pulled the old motor out, it was covered with a heavy grimy dirt that looked like it was getting pulled into the motor and decreasing efficiency. Jake was back first thing the next morning with the parts and had everything replaced and up and running in a little over an hour. Jake was professional, friendly, went out of his way to explain everything -- and my two large dogs loved him. If you are looking for a new HVAC service company, I would recommend Summit Heating and AC. Their service, responsiveness and professionalism were all worth five stars read more

I appreciate the response, but the fact is I took the time to write a detailed description of what i have been trying to et done through the website now over a week ago. After I clicked to submit it, I got the typical "thank you..." page saying my info was submitted and someone would be in touch, etc. I waited and waited (submitted after hours, as this is my only time to focus on stuff like this). After a number of days went buy, i continued to do more research and assumed maybe there was just an error, so I wrote up another detailed message and submitted it through yelp on the 5th. Here is a screenshot of my actual message (copy and paste this link into a browser: https://www.screencast.com/t/MyBJh5XH). zero response again, so this led me to my review that I left here. so there is no doubt a breakdown in your customer service, which is unfortunate for this specific situation for me. you said to call you personally, which i would have but you didnt provide any direct contact information. i understand the importance of reviews and reputations and do my research when it comes to house projects like this and was/am disappointed with this whole situation. i was looking to get someone over here for an estimate and look to hire ASAP. reconsidering all of this now, especially with the busy schedule upon me and my family. so, as you can see the ball was dropped and it took for a negative review to get any kind of response, which again is just unfortunate. read more

I am very pleased with my interaction with Brennan from Summit Heating and Air. About two weeks ago I woke up and my thermostat said the heat was on, but only cold air was blowing up from the grate. I called Summit and they told me they could have someone out to me between 12 and 2. And to their word, they were at my place by about 1:45. Almost as soon as the front was pulled off, we could see the furnace was in trouble (I just moved in and it is clear the previous owners didn't care for it at all). Brennan gave me an idea of what needed to be done and how much it would cost. He went over my poor furnace from head to toe vacuuming, cleaning and rewiring. He got the furnace up and running again! If my AC is in the same condition as my furnace, I will call on Summit again! read more

Woke up this morning with a foot of snow and a broken heater. I immediately called Summit (who has fixed my AC before) and they gave me a same day service window. I wasn't sure if anyone would be able to get through the snow. An hour later I got a call from Charlie who had transferred all his tools into his personal truck so he could get through the snow, he even showed up early. Charlie was quick, professional, and overall great. There is no reason to use anyone but Summit, their pricing is fair and the service is fantastic. Charlie went above and beyond today and earned a lifetime customer. read more

Wow, this was the absolute best HVAC service I have ever had... I read the reviews by others and decided to give them a call, absolutely amazing service! Can't recommend them enough! read more

In Oct. 2021, we purchased a 40 year old home from the original owners. While it looked like they took immaculate care of the A/C system, when we fired it up in May, it seemed like we weren't getting adequate cooling. We called Summit to help and they sent Shane Sperry, who couldn't have been more helpful. As new Coloradans, we had MANY questions about heating and cooling in general and more questions about our aging system. Shane took his time and gave his full attention as he answered each and every one. He reviewed the system in detail and provided several options for us to consider on how to maximize our setup. We were so impressed with his knowledge and attention to detail. He cleaned out our system and ran several tests to ensure it was functioning properly. He even talked us through options for when we are ready to replace the system. He was very knowledgeable about the advances in energy savings available and talked broadly about what he's seeing in new builds and customers that have opted for solar. Shane's experience and service were so excellent that Summit has gained us as customer's for life. read more

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. read more

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! read more

Craig came out to fix a busted boiler and help restore heating to our home. He was very courteous, professional and friendly. He was able to work on the issue and resolve it. Would definitely tap into the service again! read more

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! read more

I called Monday morning shortly after 9am, was put on hold and then talked to the answering service. The operator at the service could not clearly understand me at all; I had to repeat everything and spell everything more than once. It was ridiculous. Then she said that I would get a call back but she had no idea when that would be, but did say they were heavily booked. About 15 minutes later, I got a call from another woman who said she could have a tech out between 6-8pm on New Years Eve or on New Years morning for the holiday rate for an evaluation, but not anytime before. I had a bad feeling because the woman who called me back, though promptly, sounded a lot like the answering service operator. If I'm going to have to wait that long, I'd rather find another service, especially when I'm going to be charged more for waiting. read more

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. read more

We have used Summit for several years for AC and furnace repair. We had been putting off replacing our AC and furnace until we had to, but Summit was very responsive and reasonably priced. Nick and Sky were very professional and explained everything. We would highly recommend their services. read more

They hung up on me when I asked about their diagnostics charge and didn't answer when I called back.

Saw the great reviews on Yelp and scheduled a furnace inspection. The tech (C.W.) was on time, polite and explained everything he was testing on our furnace. Turns out it's in good shape! Exactly opposite from the company I wont name's tech who said i needed a new one last year. Hoping it will be a while, but I will DEF use Summit for future repairs, etc! read more

I had a great experience with Summit. My AC condensation pan wasn't draining and I couldn't clear it myself. Called Summit, got scheduled quickly, and Josh came over in a jiffy (on time) to take a look. He immediately diagnosed the problem, fixed the drain with a nitrogen line, and also explained how the system worked so I can now remedy this issue myself if it were to pop up again. The key explanation came around how the drain pump system work --- very informative. The service call is a standard $99 plus parts / materials of $30 --- I think they're worth it. read more

We needed our A/C serviced and were told by Home Depot to contact ARS. After doing some research we decided NO WAY! They have terrible reviews! Home Depot had already given them our number and it took them 4 days just to call us back! We decided to go with Summit based on their great reviews and I'm really glad we did. We received a call back the same day and a tech was able to come out within the same week. The tech, Chris, was very nice and professional and showed up on time. He was able to diagnose our problem which did not end up being costly. We only paid the $100 service fee. Unfortunately, the problem was still present 24 hours later. Chris had come out on a Friday and we were worried that we wouldn't be able to get any service on a Saturday without paying emergency fees. We called Summit Saturday morning and received a call back within an hour. The owner arrived in less than 5 min after we hung up the phone! Wow! He took a different approach and fixed the issue in less than 20 min free of charge! I highly recommend them. read more

I was able to schedule a service with ease and quick responses. the technician showed up on time and was real clean and courteous. it was for a normal service of a furnace. he checked everything on the furnace and didn't try to sell me things I don't need. he explained the companies membership to me but didn't try push it on me. he let me know what it is and what I get if not then no big deal. ill definitely have them out again when its time to start using my AC read more

On a hot day with a broken swamp cooler, Summit was a breath of fresh air (sorry, I had to). My technician was polite and informative - he explained everything he was about to do before doing it, and very quickly fixed the issue (the pump needed to be replaced). Within minutes, the swamp cooler was blowing cold air again. He gave me some advice on the best way to run it and maintain it, and I did end up signing up for the membership (since I know I'll need to service it twice a year, it's a no-brainer). Summit will be the first company I call if I run into future issues. Thank you! read more

Charlie Rutkowski was awesome! Took great care of me and was honest, upfront and communicated well.

One of the best services I received. Dean and Doug answered all my questions very quickly. They scheduled my service appointment in less than 24 hours. Chris, the certified technician, arrived right on time (literally), diagnosed and fixed the problem and completed his inspection and everything within 50 minutes. High quality service company that makes customer satisfaction their first priority. Could be a little more expensive than your average A/C guy, but it is worth every penny. These are honest people trying to provide the best service they can. I signed up for their subscription package on the same day my AC got fixed. Give these guys a chance-- you will not regret that you did. read more

My furnace went out on a day when it was -1 outside... Summit sent Ben within 2 hours of me calling and got it back up and running. Ben was SO NICE and helpful, explained what the issue was, fixed it, and suggested other optional improvements for down the road. I will definitely be using Summit again, thank you!! read more

I submitted online quote rquest,,,NO response, I called 36 hrs later still no reaponse I called a 3rd time finally spoke to someone & was told it will be another week to get someone out Their lack of interest made me question all the positive reviews read more

They were great! Brian, Craig, and Sal did a fantastic job! They were all professional, responsive when our heater broke in the winter, and were incredibly clear about what we needed and what our options were. Excited to be warm again. read more

Brian was right on time, professional and efficient. My exhaust vent pipe on my furnace had fallen and water had accumulated in the exhaust fan housing. He quickly strapped the pipe back up with heavy duty straps, drained the water and got the furnace back working. No parts were needed at this time, and he thought the fan motor was probably ok. I know what to look for to determine if it is a pressure switch or the fan should it stop working again. I like to learn how to fix as much as I can on my own, and it was great that he allowed me to watch and explained everything he was doing. Great service tech and great company. read more

I had Summit Heating & AC come to my house to diagnose my problem with my Carrier furnace. My furnace was 16 years old and it stopped working. I had general manager JT Todd and co-owner Dean Peterson came over to diagnose the problem. I knew and they also showed me that my burners were rusted pretty bad. The air/gas mixture was not properly mixing and thus my furnace was auto shutting down. Now we could have them change the burners and re-do everything, which would have been a complete teardown, or replace the furnace. We went with option 2 to replace the furnace. We replaced our Carrier with a Lennox top of the line Signature Collection SLP98V. 98% efficiency rating, Variable fan speed motor and Silent Comfort fan motor(Superior sound reduction. Very quiet). Our house 2300 Sq. Ft.(main floor and upsairs) and 1100 Sq. Ft. basement. We received three different quotes and everyone was very professional and I believe were honest. We ended up going with Summit for a couple of reasons. 1) They have a 30 day price match guarantee! If you fine anything lower they will match it! Remember has to be apples to apples. If you pick a certain model has to be the same model with the other quotes. 2) Lennox has a 10-year limited parts and control warranty, limited lifetime heat exchanger warranty(all quotes included this via Lennox). What set Summit apart is that they included: A) 10 year Labor Warranty!!!! One company , included one year labor and the other company nothing. 3) 10 year Unit Replacemnt Limited Warranty. 4) One year "Ultimate Test Drive"! If you are not satisfied with your unit they will come and uninstall your unit and give you your money back! 5) Summit also included a 1 year Safety and Efficient Agreement, which they come out and inspect your unit for one year (Fall and Spring) at no additional cost(free). The other companies did not mention any of this. Now comes the Installation specialist. I had Topher Rosales. He was very professional and courteous. When it came down from teardown to installation, you did not notice they had been there. Very clean and meticulous! We came into a little situation due to the Carrier design opposed to the Lennox design when hooking up PVC piping to my Carrier AC unit and this is where JT Todd's expertise showed! Problem solved and unit installed! I can honestly say with conviction that my overall experience with Summit was wonderful due to JT Todd(General Manager) and Topher Rosales (Installer). I look for a company to be honest, back their workmanship and products. Summit Heating & AC delivered on all three accounts! read more
