Paul has been our 'go-to' for years. Reliable, reasonable, and knowledgeable - everything you could want in an HVAC professional!

I live in Sterling Ranch, Littleton and had Paul install an AprilAire steam humidifier several years ago. I just had him come out to do maintenance servicing on our furnace and he did a great job on both the humidifier and on servicing our furnace. I will always use him again. He is very friendly, professional and very reasonable on prices. read more

Our air conditioner went out today. I called Paul about the problem. He was at the house within one hour and had the A/C up and running in no time for a very fair price. Paul was absolutely great. I highly recommend Paul for any A/C or Heating issue. tremendous! read more

Paul worked with me to replace our 20 year old house furnace on pretty short notice. Made a real effort to try and repair the old one too! Found us a good deal on a new unit and did a quality replacement job that actually improved heating, ventilation, and filtering with an added bonus of improved efficiency. It was -10 today and we are snug and warm. Very happy with Paul and Roxborough Heating and Air Conditioning, highly recommended. read more

Paul was an incredible help and literally saved me thousands of dollars compared to the intital quote I received. (from Service experts) The other company: "You need to replace your furnace" Paul: "There is a dead bird in your inducer motor" He takes it out, charges me $75 and I'm good to go. Furnace works great. Thanks for your honesty, prompt service and great integrity. I will recommend you to anybody I know and will defenitely use you again. 5 Star no doubt! read more

I have 7 rental properties. I always call Paul whenever I have a problem with furnace, AC, and water heater. Paul is very knowledgeable and the best person to deal with. He is very honest and price is always reasonable. I will always call Paul in the future for any needs. He deserves to earn 10 stars!! Thank you Paul!! read more

I have hired paul twice now once to install a new furnace in my house and once to help us handle an emergency in my daughters house! He has done an excellent job both times showed up exactly when he said he would ready to go! Got things installed professionally for a good price! In the case of the emergency he showed up within 25 minutes of being called on Thanksgiving eve and took control of the situation for us, so the houses furnace could remain on and the tenants remain safe! He handled our situation professionally and everything is back to normal. Thank you paul it's been a pleasure doing business with you! read more

I've hired Paul twice to come out and fix some issues with the furnace, and both times he was responsive, honest, knowledgeable, and more than reasonable. Couldn't ask for more in an Hvac guy, or anyone for that matter. read more

Paul explained everything and gave all the options. Very professional and extremely knowledgeable. Also his price on our new furnace was much less than other quotes. Much less. Highly recommended. read more

Wow. I'm so thankful that there are a few (or maybe just one!?) honest HVAC people in the Denver area. After several other reputable HVAC companies told me that my AC was broken and either needed to be replaced or fixed with $1000 worth of work, Paul took a look at the unit, cleaned the coils and it's working fine now! He's a kind and honest person that takes the time to explain things and answer questions. I'm VERY thankful to have found him. read more

Superior work, affordable pricing, spoke to me at 9pm, and he arrived the next day -- what more do you want in your HVAC guy?? Came highly recommended to me, so I'm doing the same! read more

Thank you Paul. I called on a hot Sunday afternoon because my AC was not cooling the house like it should. I left a message for him thinking I would hear back by Monday, but he called back within the hour. He was at my house 10 minutes after the phone call and fixed the issue in 30 minutes. The best AC service I have ever received. No extra charges for a Sunday visit. He has a customer for life! read more

Paul squeezed us in last minute to fix our AC. Very honest and trustworthy, he really knows his stuff! We will definitely call Paul in the future for any HVAC needs, highly recommend! read more

Gives you both first class quality as well as a square deal. He gives full descriptions of what needs to be done and the quality is outstanding.HIs honesty is the best. He has helped many women and older customers who were in danger of being taken advantage of by unethical contractors. read more

I called Paul to unclog my drain and he made himself available within a day to come over and fix it. He's flexible and very courteous. While he was here he also checked my furnace filter. Paul has been in my home several times to fix things and he's always been very professional and reliable. Thanks Paul :) read more

Paul was very knowledgable and saved us a bunch of money. Another company pressured us into replacing a boiler for 18 grand, but Paul was able to fix it easily. He's a very honest and reliable guy. I wish I would've found him years ago. read more

Paul stopped by and was incredibly professional and friendly. He got me up to speed on the ins and outs of my furnace. He has a superior knowledge of HVAC systems. He was honest, straight-forward, a managed a simple but competent repair, and without a doubt saved me hundreds down the road. Thank You Paul. Greg J. Highlands Ranch read more

Wouldn't recommend Paul to any HVAC work ever!!!!!! Came to my house to repair my heater. Said I needed a new blower motor, said that he might one at the shop, or even in his storage unit. Left with the motor for the evening was supposed to be back at 10:00 am next morning. No show, I called several times, and sent several txted msg. Finally responded at 12:00 saying that he was heading to see if he had one. AT 4:00 pm he responded that he didn't have one and he would have to pick one up from the mfg on Monday morning. He stated that he would be over first thing Monday with a new motor. At 1100 am monday Paul txted saying he had the motor and be over to install. I informed Paul that I contacted another company and my heater was already fixed. He stated no hard feeling, and that their would be no charge for his services. I told him to go f@@K himself!!!!!!! Stay away from this clown!!!!!!!!! read more

He's an imbecile. Can't rely on anything he says. Was referred with a warning that he's good, but never calls you back. Missed TWO appointments . Learned my lesson. read more

Instead of installing the humidifier himself, he sent his "daughter" Crystal to my condo to install an Aprilaire whole house humidifier. Not only did she install it incorrectly (connected the hot water to the intake for the humidifier), but it ended up melting the plastic tubing that she used for the water feed to the unit. This caused a massive water leak in the middle of the night, causing not only 2" of water to leak in my bathroom and laundry, but the water leaked into the unit below me, leaked into my hallway carpeting and into my closet. The damage, after the insurance payment, cost over $1,800. Then I had to also pay for the $328 damage to the unit below. After that, I had to have the humidifier unit replumbed, reinspected and reconnected for almost $300. I should have sued him to get my money back, but since he never would show when I called him for a service call, I bet he wouldn't pay for the damage, since his "daughter" did the install. I feel he is not a person that I would ever do business with again, just because he would never show up when I had problems with the heat and air that he installed in my condo unit. I only again contracted with him because of another plumber's insistence and promise of his work. I was duped and got taken. Think seriously before using this guy. He takes forever to get to a job and will not come out to fix his bad installs. read more

Paul came highly recommended to us as part of our home purchase. We decided to go with his bid because of his price and timely response. The work was supposed to be done 2 days after the house purchase closed. That was April 30th. Since then my husband and I have made several attempts to contact him. On the rare occasion where he actually answered, he made plans to come over and 4 times so far he didn't show nor did he call to explain. The work was paid for 3 months ago as part of the closing costs and he continues to avoid our calls. After 3 months of trying every avenue, we will now be hiring a lawyer to get our money back. Worst experience ever! I hesitated to even give one star as not even that is warranted. read more

We would HIGHLY recommend Paul Suppes for any HVAC needs you would have. He came and fixed our air conditioner after a 2 year AC debacle. We had quotes from 3 companies and they all said we needed a new compressor (which would be a 3rd compressor in 2 1/2 years). Paul not only said we absolutely did not need that but he fixed our AC and it runs perfectly now. His cost is very reasonable and we plan to have him do annual inspections of furnace, water heater. We would not use anyone else now. You will not be disappointed!! read more

After an informative telephone conversation, I asked Paul to come over and give me a quote on replacing our furnace. It still works, but is 35 years old. He came and gave me quotes for both an 80% and 95% efficient. While he was here, I found him to be very knowledgeable and pleasant. He also seemed to be extremely honest. He explained that most HVAC companies WAY overcharge for furnace replacement. Then he called a furnace warehouse while I listened in. I found out that a 95% efficient is $1138 (60 BTU) or $1152 (80 BTU). So, of course, anything above that is labor. (Aside: Before I got a quote from Paul, another company had given me a quote for twice the amount of any other quotes I'd received. They told me that if I went with one of the lower companies, I'd be paying for work that was duct-taped. Of course that one went into the round file immediately.) Paul's quote was significantly lower than any of the other quotes I'd received. Basically, his quote for installing a 95% efficient was about the same as I'd gotten from the other companies for the 80% efficient. So, my husband and I decided to go with him. In addition to the fair price, we took into account that he has mostly excellent reviews (although, I did see a red flag having to do with money exchanged and work uncompleted). Paul was headed out on a 2-week vacation. So, I told him we'd like to be put on his work schedule upon his return. He said he'd call as soon as he got back. He never did. I waited for about a week after his return date and then called him. At first he didn't seem to remember me. After we chatted for a minute, he said he had my estimate and we verbally agreed that he would do the install on Oct. 16th or 17th. TODAY IS THE 16TH AND I'VE NOT HEARD A PEEP FROM HIM. And, I suspect I won't. Perhaps Paul--because of his exceptional pricing--is overloaded with work. Perhaps he is unorganized and forgetful. Perhaps he is distracted by some personal crisis. Who knows? I can't imagine why he would come to my house to give me a quote (he even did some extra research on other furnace brands he doesn't normally work with at my request) and agree to do the work on a specified date and then not follow through. It's baffling. At any rate, that's why I'm giving him one star. If by chance he contacts us and follows through, I will change the rating (assuming all goes well). Until then, I guess it's back to the drawing board (*sigh*). I hope I can find an honestly-priced installer who actually shows up. Update as of 10/27: Okay, Paul did call and we scheduled a new date for install. He completed the install last week. So far, it seems to work great. He forgot to bring a receipt, so he said he'll drop it by. Overall experience: Paul is pleasant and knowledgeable and will give you the best price. However, if you are one of those folks who cares WAY more about your time than your money, you may not be satisfied. He is a one-man show. On the day of install, he arrived after 3pm. He got the unit up and running, but had to return another day to finish up some odds and ends. He said he would return the next day, but didn't and didn't call (later explained that he was working on a job in the mountains and didn't have cell reception). He showed the following day and completed the work. This is no biggie for us as I work at home, but could be irritating for someone who had to take time off. (Sorry, Paul, just being honest. Thanks for getting the job done. Don't forget that we need your Excel number for rebate and, according to the Excel website, we need to get a system rebate application from you.

Wow...what a great person to deal with. My A/C abruptly stopped working on the hottest day of the year so I placed a few phone calls to the other big HVAC services on Yelp like Summit and Dr. Fix it. Summit offered to squeeze me in 3 days later lol and Dr. Fix-it didn't even call me back. Frantic that my family was going to have to suffer through another few days of roasting in our home I placed a call to Paul on Monday morning. He was very nice and stated that he was busy but would try to come by the next morning. To my surprise he showed up a few hours later and he could not have been any nicer. He diagnosed our issue and within 15 minutes he fixed the capacitor that had blown and stayed around to make sure that the refrigerant levels were where they needed to be. He explained everything to my wife and made her feel very comfortable about what he was doing. He even offered us advice because we were using the incorrect air filters for our A/C. What a wonderful person to deal with I'll definitely be looking him up again when I need my furnace or A/C serviced. read more

Paul knows what he's talking about and doesn't charge you for repairs you don't need. He explained everything very clearly. Multiple times he has given me free advice to avoid a service call. Working with an honest HVAC person that guarantees his work is more important to me than anything else. read more

Paul is a very nice man, but very slow and not responsive to service calls. I had him install a new air system and it took him 8 hours to do it. He was called numerous times for service on the new system, yet he never responded or showed up when he said he would. He is really a nice guy, but definitely on his own time clock. If you want service now (or tomorrow, or next week or eventually 4 months later) he might show up, he might not, he might go on vacation and forget to tell you. If you have all the time in the world to wait, then good luck. He is a nice guy and knowledgeable, just not in any hurry to get the work done. He is reasonably priced, if you have a repair that he wants to do. read more

I can't speak to the quality of work. I can speak to the customer service. I scheduled two appointments. Did show up for either one. Never called to say he wasn't coming. Never called to reschedule. read more

I didn't believe there were people like this around anymore. Paul helped me out over the phone, explained the problem with my A/C, and helped me solve it. Unbelievable. His name is going up on the fridge. I wouldn't call anybody else. read more
