HVAC reviews in Westminster, Colorado

Easy to use, super professional and very knowledgeable. It is priceless to have a partner making sure my HVAC, heating and plumbing is in a good place. And Nathan crushed my hose bib install! Also - big thanks to Doug for keeping everything HVAC related running smooth and in tip top shape!

In all, I've been a Service Experts customer for more than a decade - first when I lived in Austin, TX and then as soon as I moved to Arvada, CO, I signed up with their local office. For the past few years, things have been running smooth - I'd get our HVAC system checked 2x/yr and we would receive a healthy report card. Until August 2025 that is, when the technician who came did not give us a good report card and told us that the issues we're experiencing have long-existed. We immediately had a sales person come out to quote a new system (Aug 4, 2025) and since then: radio silence. I can't get anyone to call me back after repeated attempts via phone and email. I've tried to create an online account to view my own history and attempt to reach another phone number but even that won't work because their system won't let me create an account. To create an online account, you have to provide your account #, last invoice date and last invoice amount. None of my invoices include the account number (I've gone thru them to 2023 without any invoice showing an account number).

When I lived in Austin, I referred countless friends to Service Experts and perhaps their Austin office operates differently, but I do not have kind things to say about the Denver/Westminster location. I've requested call-backs every time with their front-line CS team and no one calls me back. Only once did I get thru to someone who may have been at their physical Westminster office. That person was not interested in my concerns, did not provide a phone number I could call to follow-up on what they were going to email me (my entire service and invoice history).

I do not recommend Service Experts any longer, they've lost a decade + customer.

I recently had the pleasure of working with Nathan Jones and Luis Florez from Service Experts, and I couldn't be happier with their exceptional job installing my new tankless water heater. They demonstrated professionalism, tackled the challenge of limited space with expertise, and transformed the installation into a visually impressive setup. I highly recommend Nathan and Luis for their outstanding service

Called Service Experts Heating and Air Conditioning and was thankful they fit me in same day as my house was without hot water because my tankless Rinnai hot water heater (HWH) would only run loudly for a few seconds before shutting down with a 10 error code. Just before the technician arrived I found a 14 minute YouTube video that was a tutorial on my suspected issue with the Rinnai HWH. I watched it a few times and got started on the project as I’m relatively mechanically capable and thought it worth a try. I got the face-cover off and about that time the technician arrived. I described to him the presenting issue and I showed him a clip of the video I had watched showing that a small blower fan likely had taken in moths or lint and needed to be cleaned. Technician took a look and started talking about his dislike for Rinnai products which I now think is a reflection of his unfamiliarity with the product. Instead of removing the blower fan and cleaning it, he said it was behind a valve and something else (it wasn’t, and was already exposed) and would be “an all day project”. I recommend a possible shortcut which was me grabbing my leaf blower and attempting to clean the venting/unit in a sort of shortcut/backwards approach. It turns out, that worked, initially, and discovered that the same problem occurred minutes after I paid $310 for the service call +1 hour labor, and he left. Also, had I not recommended the blower technique that only worked temporarily, I don’t think any work would have occurred besides the tech voicing his displeasure with Rinnai.

So, another night without water, wallet $310 lighter, and I decided I’d tackle the project in the morning. I once again removed the cover plate and 1 digital display, disconnected 2 wire harnesses and removed 4 screws to then remove the expected issue, a dirty blower. It was obvious that this YouTube tutorial had accurately diagnosed the issue: the blower was filled with dead moths and their residue. I cleaned the fan with compressed air and wiped out the housing. I reassembled and tested successfully. I had repaired the HWH in about 35 minutes. I have near zero HVAC/plumbing experience other than other projects that I’ve tried on my own and I’m disappointed that I paid top dollar for this “Service Expert” technician, to not perform in any meaningful way. Further proof that more often than not, YouTube is much cheaper and more effective for many problems we may encounter with mechanical issues.

I understand that when encountering any given mechanical problem there can be any number of unknown causes and issues. I’ll never use nor recommend the “services” of Service Experts Heating and Air Conditioning”

The service from Service Expert installing team is very good. Mike managed everything well and Luke and his team are very professional and they know everything about the heating/cooling system.

Marcin did a great job today with Leo today installing our water heater. No complaints at all!

Marcin did a good job on time and did a great work! I will recommend him to do any work at my house!

Doug came out to assist us on checking out our system and was very knowledgeable, kind, and professional.

Marcin was very good with his knowledge about Plumbing and HVAC. Very high friendly costumer service as well .

I received great service from Leo
on my furnace maintenance. He
was very nice and knowledgeable.

Their service expert Nealon was phenomenal, he identified the issue, ordered the parts and installed them even with some troubleshooting to correct issues from the manufacturer (Lennox). Communication was sometimes difficult with the home office b/c your call goes to an answering service and they often don't know exactly what is going on but the local people are great.

Doug and Marcus were awesome. I had a poor experience with Applewood who initially told me my only option was replacing my entire AC unit. Luckily, I did a second opinion with Service Experts and Doug did his due diligence to understand if my machine was under warranty (it was) and to track down the piece that needed replacing as opposed to a brand new unit. Great customer experience all around!

Service Experts installed our furnace and each year are here to make sure all is running right. They have always been on time, respect our house, and take their time to make sure everything is checked. This year Abel Rascon was here and showed Service Experts only hire the best.

Nathan and Luis were excellent! They arrived on time and immediately got to work. They were able to explain what had happened, why and what would be needed to make the repair. They were very transparent on pricing and very affordable. They even claimed up after they were done. Highly recommended and we will be calling them for any future plumbing issues. Thanks guys!

I had this company install a furnace and A/C. I also purchased their service program. The system has never been worked consistently. The last service they finally determined that the return air plenum was too small. This took the over 5 years to figure out. They quoted me $1000.00 to fix this problem. I wasn’t angry that they wanted some money. I just felt that they should take some of the fee for installing the system and knowing it kept failing. I have had conversations with the call center and texts and no one has called or emailed.

5 stars is not enough!!! AC went out and they moved me to the front of the line! Installed an entirely new system the next day. Showed up early and performed flawless workmanship with professionalism... and finished early!
Luke and his team were unbelievable. I will absolutely tell all my family and friends to call Dave at Service Experts and he will make sure your needs are taken care of and act with a sense of urgency. They truly are the best! Thank you 🙏

Ronaldo & Kasey did a wonderful job.
They were very thorough.
And professional and most polite.

I recently had the pleasure of working with Marcin and Leo from Service Experts, and I couldn’t be more impressed. Marcin not only diagnosed the underlying plumbing issues but went above and beyond to fix them properly. He reinforced the shower door support and resolved a persistent faucet drip that the previous plumber could not fix. Leo’s caulking work was meticulous and far exceeded the typical standards I’ve seen. Their professionalism, skill, and attention to detail were outstanding. Highly recommend!

Got a next day appointment and the tech arrived early in the time window. Diagnosed, found the problem (loose connection) and was done in less than an hour and unit kicking out cold air again.

Follow-up review. Scheduled routine furnace checkup for 10/23/25 in advance of heating season. Tech was at my door shortly after the 4 hour arrival window started, checked out the equipment and we were done in 30-45 minutes or so. Bonus was that he had electrostatic filters that my furnace uses on his truck and I was able to purchase those, saving a trip to the office.

Jamison and Josh were fantastic. They arrived early and ready to work. They carefully walked me through all aspects of my AC and heating as well as what steps they would recommend. It was informative, thoughtful and incredibly helpful. I’ve used service experts for years to do my regular heat and AC checks as well as the replacement of part of my plumbing and their technicians have always exceeded my expectations to go above and beyond to make their work excellent and keep my system running strong.

It was a team effort between Michael Ceglia,Daniel Cameron,Mike Roark and Jared Pedri . They did an excellent job! Nice guys all. My furnace went out on Saturday and I had a new one installed on Monday.
