Extremely happy customer. Had a different company come out to look at my heater last year which wasn't heating the place well and kept shutting off. They spent 2 days looking at it and replacing parts before eventually telling me I needed to replace the whole unit. Got a second opinion from from 1st Call this year. Bill came over and fixed it, I kid you not, in less than 10 minutes. He also showed me what to look for and how to fix it myself incase it acts up again. I won't go anywhere else. They also have a convenient website which lets you schedule visits online. read more

Bill at 1st Call Heating and Air has been our go to guy for years. He has been the best, and fastest at responding to our calls we have ever had, and is the only one we will call when we have problems. Last month our central heater started giving out burning smells and not working well. Bill was able to come over right away, and diagnose the problem, then replace the 20 year old heater in a few days. About 5 years ago he fixed our air conditioner the same day we called. We love this guy and HIGHLY recommend him!! Bill explains the problems, and offers different solutions, which is much appreciated indeed. If you have any problems with your air conditioner or heater, he is the man to call!!! Honest and professional!! read more

Bill is well an experienced and straight up with honesty answer and realistic. Especially in the days where people are just eager to sell units, especially I see big push going on by big manufacturers pushing units prior to EPA 2025 refrigerant change mandate. They will be my "1st Call" for sure! read more

Fantastic company!! Furnace went out on Friday, had an appointment set up for Monday. Communication is on point. Let us know that the appointment needed to be changed to the next day due to unforeseen circumstances... very understandable. Technician came out the next day and completed the work. Provided additional care instructions that he didn't have to provide. Richard the technician and Diane on the phone were both very friendly, professional and thorough. I will definitely be referring all my friends and family to them. Price was equal to the work. Thanks so much for a job well done and, in my opinion, quickly. read more

Spent $11,000 with this company this year 2021 purchasing and installing a new furnace and air conditioning unit. I HAVE WORKED WITH THIS SERVICE FOR OVER 10 YEARS! This has been the absolute WORST experience!!! I don't know what is going on there with Bill and Diane but they were suppose to send in my $500 rebate form. I've called and emailed asking when it was sent in and they do not respond! So I called Xcel today and they NEVER SENT IT IN!!! So they have made me lose my $500 rebate!!! Also the installation was a diseaster! Because Bill is always in such a hurry he never turned the new furnace on so that night it snowed and was frigid and I had no heat! Then when he came to check the air conditioning unit so that he could fill out the rebate form he messed up my thermostat. At certain points he/they do NOT respond when I've texted, called or email just like now. It doesn't seem to register that I've been a loyal customer for more than 10 years...in fact before Bill owned this service I used them 21 years ago for the same purpose with the previous owner. I would not recommend this company at this time as something has gone very wrong with them! My response to his response it baloney! They could have stayed as long as it took! You notice, again, there is no date as to when the rebate form was supposedly mailed because it probably wasn't! I look forward to working with a more responsible, reputable company who cares about the loyalty of their clients. A company who doesn't keep talking about their poor health, poor romantic life and complaining about business. The last time Bill was here I gave him a Thank You card. He didn't give a crap, has never mentioned it or cared! read more

This may be the best experience we've ever had with a contractor and should be your 1st call. Bill came quickly, explained everything he did clearly. He is professional, knowledgeable and beyond nice. Fixed our problem with the furnace and charged a very fair price. He's been doing this for years and knows what he's doing. I'm sorry I didn't know about 1st call years ago. read more

I have known Bill, the owner of the company, for many years. He replaced my old furnace, and is now servicing my new furnace. He does a very thorough job, and always explains what he is doing and why. It is nice to have someone like him that you can trust to do a top notch job. Bill's assistant Dianne, is very efficient and timely , regarding scheduling. I highly recommend this company. Barbara C. read more

After a previous great experience with Tristian maintaining my ancient furnace, I decided that I needed to add AC to my home. At the same time update to a new furnace. Bill and the office staff were very honest that 1st call is not an authorized XCEL installer, and would not be able to process xcel rebates. Referred me to Summit (see my review. Untrustworthy sales practices). I ended up going with Coffman (see my review). I truly appreciate Bill's honest & forthright approach to running this company. If I had to do it over again, I think I would have had 1st call do the job, and not bother with the xcel rebate. Lots of problems with Coffmans install, and I have not been that impressed with the degree of remediation. read more

Our furnace stopped working all of the sudden. (It wasn't the dirty flame sensor issue). I wanted to give them a try based on number of reviews and most of them positive ones. Experience matters in this business. They were able to locate the trouble area and resolve it in expert manner instead of trying to sell us a new furnace simply because it is over 20 years old. I will definitely have them on my 1st to call list since I have few other properties. read more

I first contacted 1st Call Heating & Air for my parents' boiler a while back. They did a great job. So when my boiler started to have issues, I called them again. Bill from 1st Call Heating & Air came right away. He is very professional and knowledgeable. You can tell he's been doing this for a long time. Bill explained everything clearly to me. And he takes time to show and teach me. I learned a lot from him. I have tried a few other heating companies in the past. I have to say 1st Call Heating & Air is the best one! Diane on the phone was also very friendly and professional. I will definitely be referring all my friends and family to them. read more

I recently had to replace my furnace, and of course it was snowing and cold. 1st Call responded immediately and took great care of us! I have used 1st Call for several years now they always stand by their work, and I've always been honest. I would recommend this company to anybody. They take amazing care of me and my family. read more

Great service except for the initial repairman. A young repairman Cody was sent out initially to look at my water heater for replacement. He was unfamiliar with the somewhat-unique system (no shame in that). However, he did not communicate well with his dispatch team and I didn't receive a quote for replacement until I called. He also didn't communicate with them about my unique set-up. Also, while looking at my heat exchange in the ceiling, he dropped the panel, deforming the corner of it, and gouging out a piece of my laminate floors. That's permanent damage to my house. I had to help him put it back together. He also messed with my thermostat and re-did all of my settings. Once the confusion was cleared up by the owner Bill, they were able to replace my water heater smoothly. However, my one bad experience with the first technician has to be considered in my review. read more

I've used 1st Call multiple times. Each time they come out they're professional and quick. They even show me how to fix the problem myself. They're the only company I'll call for HVAC issues. read more

A couple of years ago our furnace quit heating late on a VERY cold day. We called and Bill came promptly even though it was late in the evening. He fixed the issue, showed me how to do it myself if it ever happened again and charged us NOTHING. Air AC started acting up recently so we called them again and Bill came out promptly and added freon. He also explained to me how and why it was only a 'band-aid'. A month later it started overheating/turning off on very hot days. So we had them install a new unit. He gave us a great deal and got it done very quickly after that first call to arrange it. I highly recommend 1st Call. They are honest and great to work with. read more

Bill - the owner of 1st Call Heating & Air - is knowledgeable, professional and fair. What more could a person want from an HVAC company? We did two fairly large projects with 1st Call this spring and summer and one of them was complex - essentially requiring Bill to figure out how to fit a square peg (new furnace) into a round hole (small, attic space). He did what we needed and went above and beyond to trouble shoot and resolve some issues that arose as part of that furnace install. After using 1st Call, I discovered friends in the area rely on them for their HVAC needs, too. Happy to have found someone I can trust for heating and cooling issues! read more

Once again 1st Call helped me out, I have been using Bill for my hvac needs for years. This time I had a clogged drain pipe which caused a leak around my furnace when I ran my a/c. It was the 4th of July holiday weekend so I opted to wait until the following Tuesday instead of having emergency service from another company. Diane called me back early Tuesday and let me know that Rich would come out to help, not only did he arrive early he did a fantastic job, cleared the clog, and checked and serviced my a/c unit outside for a great $. I love this company and recommend them to everyone! Thanks again Rich!! read more

We've been using 1st Call for 5-6 years and I can't believe it's taken me this long to write a review for them... Bill has always been straightforward and professional while absolutely standing behind his work. Recently, when selling my home with a system they installed, we had a major issue (not due to 1st Call) that nearly cost us the sale. Bill, Dianne, and the rest of the team went so far beyond any reasonable expectation that I can truly say that they are the reason we successfully closed. Thank you! read more

Started out well, with Bill calling back quickly and providing free advice and guidance over the phone. When that didn't work Bill and another person he was training came over to for a service call. They found an improperly installed condenser that was leaking into the furnace and was rusting it. They also found issues with the AC being overcharged. They put together a temporary fix and recommended a new furnace and AC. As he was tearing into things to find the water source that was leaking through the furnace, he did tell say that he didn't know what he was going to charge for this work. That's a VERY uncomfortable feeling. They were at my place for about 90 minutes and the charge was not quite double of what I expected. He did agree to put this service charge toward the installation of the new systems, if I chose to go with them. They also provided a quote for an AC and furnace on the spot, based on estimated square footage. I recently learned that the proper way to size a AC is by a (Manual "J") room by room load analysis. I will be looking for a HVAC contractor to spend a bit more time on pre-sales with me in equipment sizing based on load analysis using the Manual "J" calculations. I really appreciate the help and friendly service that Bill provided, and on short notice. But for new equipment installation, I will be doing a some more research on HVAC installers before selecting one. read more

Bill came over to fix our AC (mini split) and was really knowledgeable and easy to work with. He taught me a few new things about the unit, what to look out for, and walked me through exactly what he did. Really responsive and showed up exactly when he said he would. 1st Call is my go-to for any air needs. read more

1st Call installed a humidifier for us last week. THE GOOD- Bill, was super knowledgeable on the humidifier and installing. He quoted a price and even though the electrical work was a lot more than they thought, he stuck to it. System seems to be working well. Their staff was friendly when they were here for the install. Bill gave me lots of pointers and was very helpful and responsive to my questions even after he left. ROOM FOR IMPROVEMENT - Electrician was very nice but did not clean up saw dust and a few other materials after they left and our laundry room was a mess. read more

Great customer service! No complaints! My furnace broke down on a Sunday, the night before a big snow storm. I left a voicemail on Sunday and Diane (very nice and personable) returned my call first thing Monday. The soonest availability they had was Tuesday. Andrew came out to look at my hazardous furnace (as deemed by Xcel Energy). He was very nice and informative. When my HOA had a problem with the plans for a HE furnace, Andrew came back out to my house to find a solution with Bill, the owner. They were able to install my new furnace next day, no problem. I let them inside in the morning and trusted them enough to head off to work and let them do their job. My mom was at the house when they finished up and they showed her everything and gave lots of tips for the future. I feel like the pricing was fair, too. I will use them again in the future for sure. Thanks guys! read more

1st Call Heating & Air - My old furnace was a hazard. - Heating & Air Conditioning/HVAC Near Me - Lone Tree, Colorado

See all

Our AC in the house broke this October it just stopped working. I knew whom to contact immediately - it's "1st Call Heating & Air". Because Bill the owner came to our house last year fixing our heater, by the time he's done we were so impressed by his work and the service that I saved his contact details knowing I FINALLY found the man who has integrity and the skills we trust should anything else in the house break down in the future. So this time, I wrote to them specifically asking for Bill, they responded within minutes, and sure enough, the next day Bill showed up. not only did he fix it for us again very quickly, but also like last year, he took the time to advise us what to do to maintain it so it'll last longer. If your heater or AC at home broken down, and want someone who has honesty, integrity, and the skills along with all that old-school stuff, Bill is the man. I wouldn't bother to call anyone else but 1st Call Heating $ Air. Thank you Bill, may God bless you and your business. Be healthy and Happy Holidays! read more

I've used 1st Call for years. Mostly small things but they've been absolutely fantastic. Bill and Tristian are very nice people and they've gotten the job done. I highly recommend them! read more

I am a general contractor by trade, yesterday was one of the hottest days of the year and one of my clients had their air-conditioning go out. I went over and took a look at it and it was beyond my scope of work so we called Bill at 1st Call Heating and Air, and they send a tech out right away. The tech was not able to service the unit so and hour later bill the owner of the company came out himself and got the unit running. I would highly recommend Bill and his company, it's nice to see that they're still quality customer service out there. read more

I called 1st Call after my (now former) service company (rhymes with "mittleton") quoted me $500 for a $50 part and a one screw install, with a three day wait, after charging me $184 for a "trip" fee and a "diagnoses" fee. Although I replaced the Amazon-ordered part myself, the furnace was still giving an error code. I called Amana and they said they could not decipher the code for me for "liability reasons". They subsequently gave me a phone number of an authorized dealer to call - who was out of business! Thanks Amana! I then found 1st Call on the Amana website. After getting an appointment for the same day(!), the tech arrived, checked out the furnace and told me the code was not an error code, but an indication of fan speed and volume. Thanks Amana! 1st Call did not even charge me for the trip. They were courteous and explained how the system work. I am VERY happy and will call them the next time I need help. read more

I called 1st Call for a furnace inspection and they did a great job. Showed up within their window and charged what I was quoted. The tech was friendly and helpful. Would use them again! read more

Bill is honest and shoots straight from the hip! After having another company give us an outrageous estimate we called 1st Call Heating and Air and got an estimate that fit our budget. Bill came out and installed our furnace in no time. Included in our estimate was an air conditioner that will be installed in the spring. Great people, great service and fair prices!! They also do water heaters too! They'll be my " go to" heating and air service from this point forward! read more

We had an A.C. problem and had scheduled 1st Call to check it out. Day of the appt. a.c. started working. I explained to Tristan when he showed up that the system seemed fine but that he could check it and we'd pay for the time, since he made the trip. He was up front about basic rate and checked out the system. He informed us of a few things to watch for and said the system was fine. Then he didn't charge us. For real. That never happens. I No gimmicks. No charge. Incredible honesty and integrity. We will be calling them from here on out. Also- he was punctual, mask on, professional and friendly. Much appreciated and thanks Tristan read more

Great service, quick response, fair prices, clear upkeep/maintenance instructions, professional installation (no mess, courteous while in home, etc). Great experience with Bill and the team at first call. Highly recommend! read more

So helpful and treat their customers as valued humans. I'd recommend this business one hundred times over.

Bill was exceptional!! Explained everything to me and did such a thorough job! Highly recommend!

I have used 1st Call twice now and I couldn't be happier. Bill takes the time to thoroughly diagnose the problem and apply the most economical and effective fix. Most recently, he first walked me through a procedure to attempt a simple fix to my furnace. When that didn't work, he had me take a photo of the likely offending part and text it to him. This avoided a second visit and he came out with the replacement part in hand. Before just blindly replacing the part, he looked at other potential issues, found the root cause, and quickly fixed it - no part replacement needed! By doing a proper diagnosis, Bill saved me several hundred dollars - and he showed me how to prevent a recurrence of the problem I had. 1st Call gets my highest recommendation. read more

I cannot express how incredible Bill and his team are. They went absolutely above and beyond to help me out of a tricky situation with my AC. We purchased our home 4 months ago, and it came with an incredibly fancy and sophisticated Lennox HVAC. When our thermostat got damaged, the AC stopped working. Bill spent 10 hours at my home trying to solve the problem. I think most people would have given up, but he was persistent in helping a neighbor. These Lennox systems are so complicated it usually takes a specialist, so Bill and I certainly learned a lot along the way.. haha. After trying three different thermostats, we finally learned through consultants that my AC will ONLY talk to a specific thermostat, made by Lennox. Bill spent the next day driving all around Denver for me, trying to track down the much needed equipment - and finally found some very helpful people who gave us a deal! I'm happy to say Bill and his team did not give up on us, and bent over backwards when they didn't have to. I would say don't trust the negative reviews you see on here. He is the most compassionate and trustworthy contractor I've had the pleasure of working with! read more

We called 1st Call to get a second opinion after another company told us they would like to charge us $1500 to fix our old furnace (they also hinted that it'd be a better investment to pay them to *replace* our furnace for 4-10 thousand dollars). In contrast, Brian from 1st call showed up right on time, was pleasant to deal with and personable, and told us our furnace was fine. Cleaned and inspected it for $79 (Yelp deal), and was on his way. First call has our business now. read more

I could not speak highly enough of this company. Pricing is very open and fair. Bill came in and was able to repair a few necessary items and told us up front of a few other repairs that may need to be done in the near future. Considering we had another estimate from another company who recommended that we replace every part in the boiler room, we were very grateful. Bill walked us through everything that he was doing, showed us pictures of some potential issues, told us about ongoing maintenance, and was efficient. I would recommend them to anyone. read more

I tried to make them my first call, and second, and third...but can't get anyone to return my calls or come out to service my heating system. When I first called I did reach Bill, and he said he would call me right back with availability, but never did. I was hoping this would be a better experience than my other hvac company (who is completely unresponsive)...but guess I have to keep looking. read more

Would definitely use this crew again. Bill was very pleasant on the phone and despite my originally requesting to look at our unit the following day, he actually offered to come and look at it later that afternoon/early evening when they finished their other appointments, as it was going to be on his way. They called ahead, were on time, and quickly solved our problem. During the process, Bill and Tony walked us through every step they took to let us know what they were doing and why. This fact alone is impressive these days with everyone rushing to get done and move on, and was much appreciated! Like I said, I will be calling Bill again should anything come up in the future. Thanks guys! read more

Called 1st Call this morning. A nice lady answered the phone and took down all my info. We set the window and received a call shortly before the tech showed up. Bill, the president showed and quickly troubleshot the problem. Explained what was going on. He fixed a vacuum switch thing and got us back running in no time. Nice scheduler/staff. Called to let me know they were on their way. Nice guy and good at what he does (Bill) And lastly, I have a 30 year old furnace and not one time did he try to tell me to replace it because its to old. How many times do you hear that from the guys you see on TV. Call Bill at 1st Call Heating and Air when you need help. read more

Completely satisfied with the service they performed. Our A/C was moved by our HOA, and didn't work the same after. We rang up 1st Call to check it based on the reviews here, and Bill explained that the compressor was shot. He told us that we'd save money with a complete replacement and gave us an estimate. But he did not charge us for the visit or for checking out the unit -- he won me over with that. After calling around and confirming his was a competitive rate, we asked him to complete the job. To our surprise, he installed a larger unit for less money than what others were quoting. read more

We have had a complete air conditioning and heating system put in by this company. They were reasonable, efficient, and did a great job. They stand behind their work and come out if we have concerns. read more
