HVAC reviews in Denver, Colorado

Great job! The crew was on time and did a thorough air duct cleaning job for the entire house. I could literally feel the difference after they finished. The air is fresher, the airflow is better, and there’s no more funky smell when I turn on the AC. I highly recommend their services!

We were concerned about poor indoor air quality, and the HVAC technician checked the ducts and filters. The HVAC technician cleaned everything thoroughly and ensured airflow was unobstructed.

Having your HVAC system run smoothly is a game changer The technician arrived promptly taking about 45 minutes to perform a thorough check up They explained each step ensuring I understood what was happening I appreciated the attention to detail and the friendly advice for keeping things efficient My home feels more comfortable and I’m confident in the systems reliability

The transformation in our living space after the ventilated ceiling repair is remarkable. The team’s attention to detail and dedication to ensuring proper airflow left us impressed. Within an hour, they had effectively diagnosed and addressed the issue, explaining each step in a way that was easy for us to understand. The professionalism and courteous approach throughout the process made the experience stress-free, and the results speak for themselves. Highly recommend their expertise for any HVAC needs!

Every vent now works perfectly after their excellent repair job!

Office staff was great, and service person arrived with a call ahead on time and was very courteous and did a great job.Thank You

These guys have great customer service, knowledgeable and professional staff. They gave me the appointment on the same day. They sent their tech who came on time and fixed my issues. I recommend!

I woke up today with no heat. Called this company, guy showed up, hardly looked at much and told me I needed to spend $7500 on a new furnace.

I got another company to come take a second look. They fixed the heat within 30 minutes.

Great company! I've been using them for over a year now, and they're always able to come out when I need them. They're nice, they fix what needs fixing, and they do it all at a good price.

I have had a service contract with Dayton Heating And Air Conditioning for the past five years and thanks to their preventative maintenance my system has not failed yet. For my heat and air needs I will always stand behind this company

This place is completely unprofessional. If you have a residential job, they will not show up for your appointment and say "The technician was held up on a commercial job". They just keep pushing your appointment our further and further. Save yourself the angst and book with someone else.

I called them on Saturday morning after calling a couple of other recommended contractors that weren't available to look at an outside A/C compressor fan motor that had burnt out the night before. It sounded like an answering service, but they said they could have someone out on Monday morning between 8AM-12PM. Yay! I received an e-mail confirmation shortly thereafter. Monday came, and I waited until 11AM, then decided to call, just to confirm. The lady who answered said that they'd be out before noon. Waited until 1:30PM, then called them again. They said that a commercial job was holding them up, but they'd be out shortly. Called them again at 3:30PM to see if anyone was coming. They said no, then said that they'd have to reschedule for the following Wednesday.
I told them I had a planned hospital outpatient thing on Wed from 9AM-4PM, then work, so it wouldn't work. I'd especially taken the entire day off on Monday just to wait for them to get my A/C working again in 95-100 degree weather. Unplanned delays happen, but they couldn't have even been bothered to call, text or e-mail me to update me once. I chose them due to their 100% 5-star ratings on Google reviews. I'm re-reading the reviews now and suspect most, if not all the reviews are fakes.

COMPLETE FAIL. On 8/12 the woman on the phone seemed to not know what she was doing. She scheduled a recharge on my AC Unit for 8/15. On 8/15 their App said the job was completed so I called. She said the techs were overbooked for the entire month, that tech support marked it complete and had contacted me. At that time I had zero calls going in or out, zero texts, zero voice-mail and zero email from them. I would NOT recommend them to anyone. Seems like someone is lying or incompetent.

I am totally satisfied with Dayton Heating And Air Conditioning work and the system works great. It holds temperature within a half degree and does an excellent job controlling humidity. The air handler runs at reduced speed once the temperature approaches the thermostat setting. There are no drafts and the system is silent.

Ben was phenomenal. He diagnosed, serviced, and explained the issues succinctly. Brian was extremely professional and can also work on the older furnace we have that other companies we had could not service. We signed a service agreement and will continue to use Dayton Heating And Air Conditioning!

I’m signed up for the Fall/Spring AC and Heating maintenance program. Dayton has the best technicians! Nothing but good things to say, Ben was very professional and explained everything he found (or didn’t) during the maintenance visit in a way I can understand and educate me on steps I can take to make my air quality better. I highly recommend and wouldn’t use any other service.

Heating And Air Conditioning Denver came through for us during a last-minute emergency. Our AC failed in the middle of the night, and they showed up early the next morning. Quick service, clear communication, and no surprises. A+ experience. Thanks for the help!

After battling with my finicky thermostat for days, I was relieved when the technician arrived promptly. He quickly diagnosed the issue and had it running smoothly again in under an hour.

Seamless thermostat setup, now everything works perfectly!

After a thorough 45-minute check, my A/C is running smoothly and more efficiently than before.

Having a thermostat installed was seamless and efficient, taking just under an hour. The technician was knowledgeable, answered my questions patiently, and ensured everything was working perfectly before leaving.
