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

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

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

I was visited by a young technician named Charlie. I was pleased to hear you was certified for both heating and air conditioning and he was very quick and thorough. Kudos to the entire staff because they kept me updated for a schedule change and were very accommodating to me. The phone representative I worked with was very polite, accommodating, professional and pleasant to talk to. The rates were comparable to most other companies in the area and way under some competitors. I got what I asked for which was a timely and professional servicing of my air conditioning and heating systems by a qualified technician at a reasonable rate. I am very pleased and have no problem with spending a little over $125 once a year for some peace of mind. Thanks Summit! Rick S. Highlands Ranch read more

Tino & Craig installed a new furnace and AC the other week, thank you for the great job and identifying a leak in my crawlspace! Summit Heating and AC is very reliable and they scheduled all the electrical work and inspections. I would also like to say thank you to the office operations - everyone is always so nice and takes the time to explain things to me. Scheduling is also a breeze. read more

Tech was professional, but they made a mistake and sent the wrong kind of tech and he couldn't solve the problem... but still charged me the service call fee! read more

Fixed the broken ball valve for my outdoor sprinkler system, and replaced the pipes to and from the valve. Gave me some advice on how to best confirm that all water is removed from the outside pipes to prevent this from happening again. They did a great job with no issues read more

On a neighbor's advice we started using Summit after moving into our new home in 2016. Over the years we have found their technicians to be knowledgeable, courteous and fairly consistent. We believed in Summit to the extent that last year we signed a service agreement with them to cut down on the cost of future service calls. When we recently had scheduling issues that contrasted with the services we were accustomed to receiving from Summit they were highly responsive. The GM and owner, whom I spoke with at length, were both receptive to my feedback and offered to make it right by going above and beyond to make sure the necessary work was completed quickly and competently. I appreciate the time and effort of everyone involved as we have a unit that is fully functional (and it didn't cost a mint). As a result I'll be recommending Summit to my new neighbors...and to you. read more

Ben serviced our furnace which suddenly stopped working on extremely short notice, and on one of the coldest nights of the year. He was extremely professional, reasonably priced, efficient in fixing the issues and just an all around nice person. It's always a relief to find good help you can trust when you need it. Will be using Summit Heating again. read more

Great experience with with Summit. After an intensely hot day, our AC unit stopped working in the evening. The next morning I went through Yelp to get quotes for someone to come out and inspect it. Summit responded almost immediately and was upfront with their costs right off the bat. Once I provided a phone number they called right away and said they could have someone out by 3pm. At 2:15 I got a called from Ben stating he was 20 minutes away and actually showed up 20 minutes later, ahead of the scheduled 3pm time. Despite having a unit that is nearing probably 40 years old (no clue how it's still hanging on) he had a blown fused replaced within 30 minutes. By 3:35 we had cool air pumping into the house. Ben was a pleasure and even had me laughing which is hard to do when it's 90 degrees outside and only a few degrees colder inside. I definitley recommend Summit for your cooling needs! read more

To Jason and Summit, I do not write reviews, but I have to say that Jason did an outstanding job at my home today providing me with quick efficient service. Being a disabled individual is tough, I had a issue with a tree branch and Jason took care of it for me this to me speaks of service that I wouldn't expect nowadays. I would highly recommend Summit to anybody that needs service on their AC. Troy read more

I've scheduled an annual boiler service appointment with summit three times now and have consistently been impressed with their compassion and professionalism. Today's service with Jake was exceptional even by summit's standards. He took the time to help me understand each component of the boiler system and how he was evaluating its performance. I really enjoyed learning about such a critical system within my house and being able to freely converse with an expert. Thank you, Jake! read more

Our 2-stage furnace was running on the low setting and not keeping up with the cold. With a 25 day old infant in the house, we felt that we had an emergency repair needed. I called and was bumped quickly to the front of the line. Within a few hours, the technician (Charlie) called and came to the house. He readjusted the furnace after some quick online research on my furnace model, and it works like brand new. The technician was professional in presentation and performance. He took the time to explain to me what was happening and how it was fixed. Additionally, the initial answer on the phone in their office was pleasant, efficient, and responsive. Summit provides immediate email records of the invoice and services. No unnecessary paperwork. Top notch service! read more

Fantastic experience through and through for my mini-split system installation. Jeremy was extremely helpful and knowledgeable for the estimate on the new system, and provided assistance every step of the way. Jack and Sky handled the install, and they knocked it out of the park. They displayed awesome attention to detail and professionalism for the entire install and my new mini splits work perfectly! Everything was done on time, correctly, and with plenty of communication. I'd 100% hire them again and recommend them to others. read more

Wow , I really don't know how to express my self any more then this. Summit Heating and Air is a great company , with great employees that are about the customer. Ben Andrew's was the technician that came out to my home , to service my gas furnace and my central air conditioner. My furnace is 18 years old and needed a tune up along with the central air conditioner. Ben took time to hear what was going on with my furnace and the issues that I am starting have with it. Ben inspected my furnace, he cleaned my fan , my a/c coils and explained to me that a certain part was going out on my furnace and gave me the price for it . To make a long story short Ben was professional, courteous, very nice to talk to and listen to what I had to say . All and All my Gas furnace works like it's new again and my Central air conditioner is cooling my house better then it has in years. Thank You Summit heating and air for such a great technician and great customer service. If I have any more issues on my a/c or heating I will for sure call SUMMIT HEATING & AIR. Great work guys. And great work Ben. read more

We want to give a huge shout out to an amazing plumber, Carlos! He is truly amazing at what he did for us...finding a difficult problem and fixing it! What a big relief for us! Thank you so much! read more

My heat was not working properly and Joe M came out to take a looking. He assessed the situation and quickly let me know what was going on. He replaced my thermostat and now my heat is working great! Very professional. Would highly recommend Summit and specifically Joe! read more

I had Summit install a new Navien tankless water heater, new Daikin furnace/AC, and new ductwork in my 1920s home. My great experience started with an estimate from Mike. He was timely, professional, and informative in helping me determine how to handle the transition from an outdated coal/natural gas-converted gravity furnace and oversized ductwork to a modern HVAC system. He was quick to respond to my questions and concerns. My experience with him, the countless 5-star reviews, and the Summit '100% Right or 100% Free guarantee' pushed me to select Summit for the work, even with a few lower estimates to consider. When it was time for the actual installation, Jake and Travis were absolutely amazing, providing a top-notch installation and going above and beyond to explain their work throughout the process. They created a friendly, welcoming environment in my home and were eager to answer any and all questions/concerns I had. Both Jake and Travis were incredibly knowledgeable about all things HVAC, and the great pride they take in their work was readily apparent when looking at the quality of the installation. read more

We have used Summit to replace the AC at our last two homes and they will always be our first choice. Their techs are well trained, experienced, and professional. There are multiple people checking every step of the process. The job is not done until you're completely satisfied. We also upgraded the air filter and upsized the return/supply ducts to improve airflow. The permit always has to find something and their electricians immediately made any needed changes. We also appreciate their after support regular maintenance. Summit will not be the cheapest, but they will be the best choice. read more

From start to finish, Summit Heating is all about customer service. We are part of their membership program and they have serviced our swamp cooler in the past. We were looking to replace our 20+ yr old furnace, they were able to provide a competitive quote, great warranty, arrange with the electrician, etc. Sal and his team installed our new furnace, made sure to protect our floors (and clean them after), all the parts look beautiful, fresh and well put. Sal was friendly, informative and thoughtful. We are thrilled with our new furnace and we look forward to hire Summit for other home upgrades in the future. I'll try to keep this review updated in the future! read more

Summit is such a wonderful, responsive company - there is no lead to look any further for help with heating or A/C issues. In February we had the wonderful experience of our old heater blowing cold air. Not good. Summit was the only company that answered the phone and came out the same day to get it up and running. Thanks Josh! Fast forward to two months later when the silly old heater decided to play a funny joke and blow cold air again. Classic. We already knew and had been saving to replace the system, so instead of band-aids every couple months, we decided it was time to bite the bullet and install an updated, energy efficient system. Knowing how straightforward and honest our first experience was, we were very comfortable reaching out to have Summit Heating and Air Conditioning take on the job. Dianne helped schedule an appointment for us with friendly service, and Chris M. came to our house and spent some quality time taking the appropriate measurements to determine which system would meet our family's needs. Some companies sell a one-size fits all system, but we were given options and had them all clearly explained. He was patient with our dog climbing all over him while he shared the ins and outs. After that meeting, we decided to get it all done at once since the systems we had in place were old, and not energy efficient. New Furnace, new A/C, and new water heater - hoping for peace of mind and energy savings. Summit even helps with all of the rebates through XCel Energy and even with manufacturer's rebates that bring the total costs down. While this is a big expense - they get the job done so professionally and promptly it is 100% worth the money. On install day, Craig offered to treat my wife and I coffee, then he and his apprentice Diego removed the old clunkers and installed the new systems in a flash. They made sure our house remained clean and tidy through the whole process. I'm still not sure how they fit the water heater down the basement staircase, but there wasn't even a scratch on the wall. The utility room never looked so organized. They cleaned up how exhaust pipes run, secured the insulated pipes that run to the A/C system in a way that made more sense, and even moved the water heater to give us more storage space. That really counts in these old houses! Craig and Diego are both real pros and take pride in their work getting everything up to code. Great service and work from start to finish! Stop looking around and comparing other companies, with Summit, you'll save future headaches and have a smooth experience. read more

We called Summit on a Tuesday, and the technician (Josh) was here by Wednesday. Super quick turnaround! Not only that, but Josh reached out and asked if it was okay if he arrived early to which we happily agreed. When your furnace stops working in the middle of back-to-back snow days, the quicker the better. He was in and out within about 30 minutes and got it all fixed, as well as checked on our 2nd furnace to ensure they were both good to go for us moving forward, which was super thoughtful. He showed my husband what the problem was and explained everything he did. We ended up joining Summit's club membership because Josh's service was so great! It's very reassuring to know we have someone to go to that we can trust when these issues inevitably pop up. Thank you Josh for the friendly & efficient service! :) read more

We are very happy to have had Summit install our new high-efficiency furnace and A/C, replacing a twenty year old system. Shane and Sal led the team, and they were great to work with. We were also impressed with the professionalism of everyone else who was involved. Great job! read more

We had them do our furnace and AC back in November and it seemed good at first but we had to have them come out multiple times due to the AC unit being DOA but took multiple calls for me to get that scheduled when I was told I'd hear back the next day. So two weeks after I was told I'd hear we finally get it scheduled then when it got installed they never connected the condensate so water did get all over the basement and they tripped the garage and back patio power and when I called to get some help to fix that I was told I'd hear back right then and no one ever called me. They had to send out a crew the next week to check everything one more time since there were so many misses. This seems like it would meet their 100% right or 100% free claim on the website or at least just some compensation back but after a week of waiting to hear on that, we were told we will get nothing. Just wasn't worth the headache and lack of communication. read more

These guys are 5 star for a reason. Today was the first freeze of the year (and a Sunday) and our heater went out. I used Yelp, requested a quote, and 10 minutes later got a phone call this sunday morning. The lady told me they could have someone here a couple hours from now. Josh showed up, fixed our igniter, and was out fast. We knew this would be an expensive fix but what he quoted us was cheaper than we had anticipated. Fantastic job and I highly reccommend them. John read more

Had a great experience from start to finish with Summit Heating & Air Conditioning! We noticed the smell of burnt plastic coming out of our vents so the next day I took to Yelp to find an HVAC company and thanks to the recommendations on Yelp I decided to submit a request to Summit on their website. They responded withing about 15 minutes and the woman on the phone was extremely kind and empathetic to my situation and got me scheduled with Josh for 5:00 pm that day, which was perfect for my work schedule. Josh was not only on-time he was about 10 minutes early, which was unfortunate for me as I was about 5 minutes late ;) After patiently waiting for me to arrive Josh did a great job in efficiently diagnosing the issue, finding the best and most cost effective solution for me and thoroughly explaining my options. After that he was able to perform the repair on the spot and he was in and out of my house in about an hour and 15 minutes total and was off to his next job. Josh was very polite and easy to talk to and displayed excellent customer service skills, which can be rare for a contractor. Summit is about as organized and customer-service oriented a HVAC company you could ever ask for, I would highly recommend their services! read more

Website explicitly states that they offer free estimates. They however required a $50 service charge to come out and give a quote and refused to give any type of estimated range for the service. Would not recommend. read more

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. read more

I would 100% recommend Summit Heating & AC. Sal and Casey did an exceptional job installing a new AC and furnace for our home. They were prompt, professional, clean and informative, not to mention very kind. We are grateful for the work done and would absolutely recommend this company!! read more

I had air flow issues on the 2nd floor of my house - either hot in summer or frigid in winter. I looked at reviews on Yelp & Google and saw saw Summit had impeccable reviews, so I thought I would give them a try. It took a bit to get an appointment. That was ok with me bough b/c that meant they were in demand! The tech that came to the house, Josh, was professional, courteous, and quite knowledgeable. Unfortunately for me, he recommended complete system replacement as my furnace/AC was at end of life. Josh said he'd have the main office call to get a sales rep out to the house. That same day I had a phone call from the main office and an appointment with a sales rep for the following day. Quite efficient, which I truly appreciated. The sales rep that came to my house, Eric, was outstanding. No pressure, no nonsense - he just told it how it was. We discussed my needs and the state of my HVAC system. He helped me to settle on a new furnace that was not the top of the line system (thus saving me $$$) b/c that was the best for my situation. I truly appreciated his honesty and knowledge. A few weeks later, Craig & Omar did the actual installation of my new furnace. They too were knowledgeable, courteous, and took extreme care of my house. After completion, Chad walked me through the functionality of the new system. I'm not a big online reviewer, but was so impressed from start to end with Summit that I felt compelled to write something. Top notch company and a no-brainer choice for HVAC needs. You've earned a customer for life. read more

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. read more

After having dealt with 4 different HVAC companies in Denver, these guys are a breath of fresh air (budumtish). So far, they've worked on my heating, A/C, installed an Aprilaire whole-house steam humidifier, and connected everything to a Nest thermostat. They're always punctual (or let you know if they're running late), always professional, happy to explain everything and always willing to help. On his way today, the tech (Josh) even called to ask if I needed anything picked up on his way here. If they ever don't know the answer to something, they call the manufacturer or do their own research to get you the answer. 100% recommend these guys for any HVAC needs you may have. read more

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. read more

Summit Heating and A/C came out to give me an estimate on a Mitsubishi mini split in 1 business day. The Jeremy was prompt, polite, knowledgeable and provided a bid on the spot. They were able to come out the very next day with the unit. Dave and Tim arrived as the installers, again on time, with all the necessary tools and parts, with a complete understanding of the project. The install was seamless, and they were so neat and clean I had absolutely no dust or anything to clean up when they left. They are also processing the paperwork for a rebate and will coordinate the inspection. I cannot recommend this company more strongly! read more

I am super impressed with Summit and in particular Josh who conducted my service and Jeanette who got the service rolling. My furnace has been acting up for about 2 weeks. I was very nervous since it's been very cold and the last thing I need is for it to croak altogether right now. Unable to get a reply from the HVAC company I have used in the past, I called another HVAC company that had sent a coupon to my house. Long story short I was told my furnace had a fan motor on it's way out and the cost to replace would be over $1000. I knew that had to be really off the charts out to lunch so after that company left I did what I should have done BEFORE I called them and read the Yelp reviews on them and about 90% of the reviews were not good and mentioned price gouging in particular. So I Yelped HVAC and found and called Summit for a second opinion based on their reviews. Josh showed up on time and went to work. After about 20 minutes I was alerted my fan motor was fine. Furnace has some age but certainly nowhere near the end of its life. The issue was my poorly designed filter box and undersized filter causing poor airflow tripping a heat sensor. Josh even had an easy fix (much bigger filter and positioned better to allow more airflow) and furnace is working like a charm now. I have a new HVAC company and it is called Summit. :-) Honesty and Integrity are huge with me. Summit gets my vote. read more

When I saw over a hundred 5-star reviews I knew I had to give them a shot. 97 degrees and the air conditioner goes out. Called five places and spoke to one company scheduling three weeks out. The other four I just left messages - subsequently a few days later no returned calls. So I turn to my Yelp community and pick three to request a quote. Response via Yelp in minutes that I will get a call. A couple hours later I received a call. They can come out tonight between 7pm and 9pm. Are you kidding me, same day service? Yes they were going to charge a little more, but who cares! I finally got a response back from the other companies after Summit had already fixed my problem. If you're cheap and want to wait three weeks go elsewhere. If you need heat or air conditioning sooner, CALL SUMMIT! read more

So it just keeps getting worse. I had a master plumber come out and check my tankless because the tankless wasn't functioning properly. Turns out they installed all of it incorrectly. At the time they had installed my furnace and tankless 4 years ago, the gas line size that I had would not be able to provide the amount of gas for the BTUs needed so my system has been running improperly for 4 years. They further discovered that all dip switches were set incorrectly, condensate line is installed incorrectly causing condensate trap to get clogged every time it fires gas, pressures were set incorrectly, condensate line was not draining into a proper drain and is just running with 3/8 vinyl tubing over to corner of floor which is very much against code, they installed a PVC line taped to the vinyl tubing that is getting clogged causing condensate to back up, and condensate line for furnace is draining outside which is also against cold which could cause freezing etc. etc. read more

Everyone I had contact with was fantastic! Our furnace stopped working this morning and I was freaking out. I did a bunch of online research and reached out to Summit through the Yelp app. Doug responded to my request in less than 15 minutes and Jeanette (I think that was her name. I apologize if I am remembering incorrectly.) called me just a few minutes later to schedule the appointment. Jeanette let me know that they likely wouldn't be able to get anyone out until after hours and was very clear what the charge for after hours work would be and got us on the schedule. I got a call from the technician, Herb, around 4:00 to let me know that he could be here in 15 minutes. Herb got our furnace up and running in no time. Herb was kind and curtoeous and made sure that I understood what was going on. This was a best-case scenario after waking up to no heat. Thank you to everyone at Summit! I will absolutely be calling the next time i need heating/cooling expertise. read more

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. read more

It's not fun having your furnace quit in the winter - it has one job! Herb arrived promptly at the time of the appointment. He called me before to give me a heads up. He was very courteous and professional and not only fixed my furnace problem (explaining the issue to me before he did the work) but he also corrected another issue he found with my humidifier. It was easy to schedule the appointment with Summit. They are a great organization and I will definitely be calling them in the future. read more
