We called HeatWave right before the big snowstorm because our heat went out. We called them about 8PM the night before and Dimitri answered and was extremely helpful in setting up an appointment for the next morning. The quick response was exactly what we were looking for. Dimitri ran some tests and figured out what was wrong quickly, but he did not carry a control board with him as it isn't a common issue. This was about 5PM and the snow had already started. He said he would be back first thing in the morning and he was! He was able to make it through the terrible weather and traffic to bring us our control board and get it installed. After that there was another thing wrong with one of the switches, and because Dimitri wasn't able to tell us that beforehand because there was no way of knowing, but he was able to replace the switch as well and didn't charge us for it! The overall price we got for this service was unbelievable and WAY BETTER than anywhere else we saw online (Even the Groupon offers)! Dimitri was extremely professional and is a great guy who knew what he was doing and was able to explain everything 100% to me during the whole repair. I would recommend this service to anyone who has problems with HVAC and I will be referring Dimitri to anyone I come across who needs HVAC repair. 5-stars was the easiest decision I've ever made. Thank you Dimitri! read more

My air conditioner happened to go out right around the time a heat wave hit the Denver area. I was desparate for someone to get it working asap. The first company I called diagnosed the air conditioner compressor as on the brink, but did get the air conditioner working again. That lasted for about 24 hours and then the AC was only blowing warm air once again. My tenant then got the company that had serviced our heater in the past to come by and see what they could do. They fixed it also, but again 24 hours later, the fan was blowing hot air. They came back another time later and got it to work another 24 hours. Of course, there were days of no AC between those calls. I used Yelp to help me find another AC company...read the great reviews about Heatwave and Dimitri, but he was overbooked as it was primetime for AC repair throughout the area. After some time, I called him once again as I was getting frustrated. He was understanding and able to fit me in his schedule, came by, and the diagnosis ended up being the thermostat not working correctly. He put in another thermostat, and saved me thousands of dollars as I didn't need another air conditioner after all. But when I do need more AC repair or to replace the AC, I will definitely call Dimitri! He is a no nonsense, smart and COOL HVAC kind of guy! read more

Dimitri came over to my house today to give me a quote on replacing my furnace which stop working properly. He came all the way up from Parker to my house in Lafayette because I wanted a quote on a new installation, not a service call. Another company had inspected it and suggested that it should be replace. Dimitri was the third company I had over to give me a bid. My other two quotes ranged from $5,000 to $7,000. But instead of the other two, well known in the area, he had my furnace back up and running in 15 minutes. Cleaned the flame sensor and adjusted the gas pressure to the unit. Like the others I didn't ask if they would check it out first, Dimitri just got right to it and said don't worry I'll fix this. We agreed it's working fine so no need to replace it, but if I ever wanted to he could do the same heater swap out for $3,000. So I asked him what do I owe you, Nothing he said. Really, that wasn't good enough for me so I made him take a hundred bucks. Dimitri is about honesty and earning respect for the industry he choose to work in. All 19 years. I'm thankful for people like him, we need more of them. read more

I don't usually write reviews (I use Yelp to find good food/services like most people), but Dimitri was just too good to keep to myself. Like so many reviewers of Heatwave, I woke up at 5:00 AM to a freezing house. I ran through the usual troubleshooting process and discovered that it wasn't anything simple, and was able to diagnose to the point where I knew it was most likely the ignitor (use the LED code on the furnace door if you can). Based on Yelp reviews, I called Dimitri at about 6:30 AM on New Years Eve, and he answered the phone! He was starting an install for another customer at 9:00 AM, but promised to be here by 8:00 AM to see if he could fix it...which of course he did. He was extremely knowledgeable, professional, and very clean. While he was in the HVAC closet he actually spotted a few potential issues with the cooling system, so I will be scheduling him to come back out before i turn that on in the summer. There is no question I will continue to use Dimitri for anything HVAC related, and I HIGHLY recommend you do the same. Top notch service! read more

I highly recommend Heatwave Heating & Cooling. My condenser broke down and the fan was not working. Dimitri looked at my entire system which is 12 years old. He gave me some great suggestions and things to watch, due to the age and the overall system starting to exceed its useful life. But he stated there was no need to replace the entire unit now, as my unit will continue to operate well. He mentioned we will just repair it as the individual parts go out. He fixed the part and we were back up and running with no issues. He is a top notch professional who treated the unit and my house like it was his own. Dimitri is a professional who has tons of knowledge in the heating and a/c business and did only those repairs that were needed. I am very particular in who I recommend and my expectations are high in that they do an outstanding job. Heatwave Heating & Cooling and Dimitri exceeded those expectations and they are on the top of my list for any of my clients, friends, or family members who need a HVAC repair company. read more

Add me to the list. Furnace didn't come on. I replaced the thermostat and that didn't work. I texted and they was here after he finished his current service call. The furnace is 23 years old. It has a visible crack on the fan, missing screws on the humidifier, and obviously not very well maintained. I fully expected Dimitri to take one look at it and say it had to be replaced. Nope... he ran a few tests and replaced the burnt out fuse. 20 minutes and $99 service fee later we have a working furnace. (with the understanding that he didn't know why the fuse blew out and that it could happen again) He was honest and told me my furnace is past its useful life and that it is due to be replaced. However there was no scare tactics about it having to been done now. I asked for and got a quote for a replacement (which sounded very reasonable ) and I'll be able to save up for the replacement instead of having to put it on credit if I had to do it now. read more

Dmitri is absolutely awesome! He installed a new AC unit in our house and had to come back out a few weeks later to replace a bad coil. I can't say enough good things about him. 1. He is always very concerned about his customers and that they are happy with his service. 2. He has the best prices in town. 3. He works long hours as needed to get the job done. Twice when he came it was after 6:00pm and he would have appointments to go to at 9:00 or 10:00pm so customers were taken care of. 4. He gives an estimated time of arrival and sticks to it (in fact, he always called to let me know when he was on his way....so that I wasn't sitting around waiting for hours). 5. He is very knowledgeable. We had two other AC service companies inspect the unit or try to fix the problem before we called Dimitri. He was able to figure out the problem immediately and knew how to fix it. Thank you, Dmitri! You will be our go-to person from now on! read more

Highly recommend Heatwave Heating & Cooling! After working with what I thought was a reputable HVAC company who failed to fix my air conditioner after several times I called Heatwave heating and cooling for a second opinion and spoke to Dimitri. He got to my door within minutes to properly diagnose the problem. Wow! Talk about fast service! Upon his immediate inspection he discovered the many errors the previous company made and quickly fixed the problems. He even took the extra steps to inspect the entire AC unit to make sure everything was working properly and also inspected my indoor furnace too at no extra charge. He was super friendly and really informative about my entire HVAC system. A true professional who is extremely honest and really knows his stuff! Dont waste your time with anyone else! If you have any heating or cooling issues call Heatwave and get it done right...the first time! read more

This review is long overdue! Back in November 2024, I had an issue with my furnace, so I called for service. Dimitri came out for an inspection and quickly diagnosed the problem--a failed motor on my 20-year-old unit. I wasn't keen on putting more money into an aging system, but the cost of a new furnace was a big consideration. Dimitri was incredibly helpful in guiding me to a cost-effective unit that met my needs without breaking the bank. Shortly after, Ivan and another technician came out for the installation. They worked efficiently and professionally, completing the job quickly while making sure to answer all my questions. Their workmanship was exceptional and it's clear they really know their stuff. I couldn't be happier with the service and will definitely call them again for any future HVAC needs. Highly recommend! read more

Our AC wasn't cooling properly. We had a different HVAC company take a look at our AC and were told that it was too old to repair and we would need to replace the AC as well as the furnace at a very high cost. We called Dimitri/Heatwave for a second quote. Dimitri actually dug into the issue and offered alternatives. He said there were some things we could try short of replacement but did acknowledge the age of the AC and furnace. He provided a quote for repair as well as replacement. The quote for replacement for both the AC and the furnace was $8000 less than the other company. We opted for replacement and Dimitri's crew completed the job two days later and in a professional and efficient manner. We appreciated Dimitri's honesty and thoroughness in addressing our problem. Would definitely recommend! read more

My husband found Heatwave through Yelp due to the great reviews. Meeting Dimitri today, I can see why there are so many 5 star ratings! We were able to make a same-day appointment to diagnose a recently broken AC. Dimitri arrived right on time and was extremely courteous and professional. He quickly navigated the problem, explaining each step along the way and showed me pictures on his phone of the damage he was seeing on our AC. Unfortunately, our AC was beyond repair and we will have to get a replacement in the future. Dimitri offered me his professional opinion of what he would do in this situation, weighing out the different options and did not even charge us for diagnosing the problem! I would recommend working with HeatWave to anyone for an overall great experience. read more

Great customer service! My heater went out in frigid cold weather in late afternoon. I called several HVAC companies and no one could come out on the same day. After reviewing the reviews on yelp, I called Dimitri who was also booked through late night. However, Dimitri spent time with me asking about the problem and providing some suggestions for fixing the problem on my own. Which vendor does this? Dimitri showed care for my family so that we would not have to spend a night in the cold. Unfortunately, the suggestions did not resolve the problem, but I greatly appreciated the effort and concern. Dimitri was able to come by the next day and was able to repair the problem with a new motor. He was punctual, professional, and efficient in his work. Highly recommended! read more

Dimitri was terrific. Our 20-year-old furnace was failing in early spring as cold weather lingered. I gave him a call and he arrived at our house within an hour on a Saturday. After a thorough inspection, he was apologetic in informing me of the bad news that the furnace would need to be replaced soon. I wasn't surprised as I knew the system was on its last legs after taking a beating by Colorado winters. By replacing a part he was able to get it going again so that we wouldn't have to make a rushed decision. He also inspected for carbon monoxide and corrected the work of a previous contractor. Dimitri couldn't have been nicer and more professional. He answered all of my questions. He'll be getting our business in the future for sure. read more

I got the dreaded call from a renter this morning at 10:40am - "Sorry to bother you, but the A/C is just blowing hot air..." So I called my regular company, but they could not be out until 12-4 on Monday (this was a Friday morning). So I googled "Denver HVAC" - saw the Yelp article, and Heatwave was my first call - and the only call I needed! Dimitri was the one that answered the phone, and was at the rental less than an hour later. He diagnosed and fixed the problem within an hour - and it was NOT the $7-10K bill I was worried it was going to be! I can't recommend Heatwave and Dimitri enough! Fair and honest - which is all you can really ask for in a service company! I have already recommended him to a friend! read more

I called Dimitri to diagnose a problem with my furnace that another company had failed to find on 3 different visits to my house. He was able to find the problem and and fix it the same day. Dimitri arrived on time, when he said he would and took the time to explain the function of the components in the furnace. He showed me proof that the parts were malfunctioning and gave me a breakdown of the cost for the repairs. The prices were fair and the repairs were done in a timely manner. Dimitri was very professional in appearance and in the way he interacted with me. He was very respectful to my home and cleaned up before he left. My furnace is working better than ever and I plan on calling Dimitri from now on. read more

I can't even explain how grateful I am for Dimitri at Heatwave. I was without heat for almost 2 month because the cheap furnace I had in my house was no longer safe to use. I've tried to find a reasonable replacement that I could afford and no one other Heat and Cooling Business in Denver was willing to give me a good deal. It was extremely stressful because I had to worry about frozen pipes on top of it. I called Heatwave spoke to Dimitri and he gave me the best deal ever was there the day after we spoke to install a Trane Furnace with Warranty and everything. He surely was a Christmas miracle. Dimitri is very professional with a heart of an angel. I will only give my heating and cooling business to Heatwave. read more

I recently called Heatwave to have them service/clean my A/C. I found their name on Nextdoor.com - several neighbors had recommended him. Dimitri got right back to me. Boy am I glad that I used him! He found that my furnace had never been installed right, so it wasn't working to its full efficiency. And he walked me through everything and showed me everything he found/did. Dimitri, the owner, was very friendly, efficient, helpful, honest, and great to work with. I am using Heatwave from now on! There are too many shysters out there who will work on your furnace and just screw things up (but still charge you for it). This guy is the real deal. He knows his stuff! And he's not overpriced like some. read more

I could not be more pleased with Dimitri's work. He saved my husband and I over $10,000 today! After our furnace stopped working last week, I made various appointments with different HVAC companies. The first company that came out said we needed to stop wasting money with fixing our furnace and just replace it outright - a $10,000 job! Luckily Dimitri was the next appointment of the day and he became Superman. A simple exposed wire from our humidifier was shorting out the heating system. I am still in disbelief that such a simple fix finally turned our heat back on! I will now only trust Dimitri with anything HVAC-related and am so glad to have found an honorable worker! Thank you! read more

When you find a great HVAC company you can trust, you've got to share. Second time I've used Heatwave Heating and Cooling. The first time was about 8 years ago when Dimitri re-did some duct work and installed my humidifier at 1/2 the price of other quotes and did amazing work! Today, when it was 8 degrees outside, my upstairs furnace decided to die on me. Called Dimitri and within a few hours he came by, diagnosed and repaired my furnace. While he was out getting the part, I called two other shops for an over the phone estimate and they were both 20-30% higher. Highly recommend Heatwave Heating and Cooling! http://www.heatwavedenver.com/ 720-600-7247 read more
