My experience with Denver's Best Heating and AC Repair was wonderful! My furnace was not heating when I woke up and I knew that it was time for the replacement. I called Denver's Best and they scheduled the appointment for an estimate. Adolph was my technician. He took time to explain the options and recommended the system that would fit my budget.

Great service and communication! Our furnace went out during a cold spell and they were able to get us back up and running within a day. The team was easy to work with and explained everything well. Alfredo, Merrill and Lisa went above and beyond to take care of us! Highly recommend!

Thank so much to Denver’s Best Heating and Ac Repair! This team is awesome, came and addressed my furnace repair problem in my home before the day even ended. Highly recommend will call again if any issues come up again in the future.

The only name in HVAC for me. I personally use him and refer him to my clients also.

We've had great service with Charlie's Heating and Cooling. We have an older system and have been told by other companies that the system needs to be replaced. With Charlie's Heating and Cooling , they have fixed a few minor things and the system works great. No arm and a leg charges either.
He's now our go to guy for any needs we might have with the heater or our air conditioner.

I paid a large amount of money to have an A/C unit installed by another company. That other company came out to repair my new unit on no less than eight occasions to no avail. I was basically told that the product they provided was the best they could do. I called Michael at Charlie's Heating and Cooling and simply asked him to come and look at my non-working unit. Michael came out and within an hour he had repaired my unit. What the original company could not handle, Michael fixed in an hour at a more than fair price.

There are not words to explain how professional, knowledgeable, and fair Michael is. He is the epitome of a skilled professional. I would recommend this company to anybody. I had lost faith in the heating and cooling industry. Charlie's Heating and Cooling has not only restored my faith in the industry, but also in humanity.

If you are wondering if this company is worth your time calling STOP looking and call! Michael was awesome to work with and will give you the best price and workmanship for any project. We had him run a gas line to our fire pit and he made sure it was prefect!

I recently used Michael for my HVAC work in a whole-home remodeling project. He re-routed numerous heat ducts and connected numerous vent fans, and did a very nice job at a reasonable cost. I use tradespeople a lot in my business and was very pleased with his work. I look forward to using Michael on future projects.

Charlie’s Heating and Cooling installed my furnace over a decade ago. My home originally had no furnace so the entire system, furnace, vents and everything needed to be installed. Everything was flawless and my system has worked great and it is the best system. I could not be happier. Whenever anything is needed for my house HVAC related, Michael is the only one I would trust. Michael’s work is top-notch! His work is always done 100% perfect and his prices are fair and he is so courteous and is always patient with all my questions. I have done a lot of remodeling in my house and Michael has always been my favorite! It is always so nice to see him when he comes out to do our routine HVAC maintenance. If you need any HVAC work done, do not hesitate to call Michael. A+++++ all around!!!! HIGHLY RECOMMENDED!!!!!!!!!!!

I cannot say enough great things about Michael and Charlie's Heating and Cooling. He installed a two-zone, ducted mini-split system, in a house with no existing ductwork and one of the more funky roof configurations, and it's working beautifully. He was adaptable and accommodating, provided guidance when requested and pivoted when asked. And, he was extremely efficient. The only downside is that with how great a service he provided, I don't know that we'll have a need for his services again!

Michael helped us with previous service and also with our new ecobee thermostat system--and expertly installed a humidifier on our second furnace. He recently evaluated and quickly repaired one furnace--and thoroughly cleaned both furnaces. He's very timely and professional--he's definitely earned us as a customer for the future!

Michael installed a gas line for a fire pit as well as hooked up line to fire pit. He also created a sweet panel for the igniter switch and turn on key. Was very professional and did quality work.

We have been relying on Comfort Zone HVAC Service for the past few years after a friend recommended them. The only other company we considered didn’t meet our expectations, so we are glad we found this one. They are always quick to respond, responsible, and respectful, ensuring you are satisfied with their work. Being a family-run business means we see the same friendly faces during each visit. They worked on our duct system and improved the airflow throughout our home. Now, the airflow is perfectly balanced—gentle in the less-used rooms and just right in the areas we use regularly. They also replaced our air conditioning unit, offering a price that was about $1000 less than what we found at Costco. Most of the installation was finished in just one day. There was a little hiccup with the placement of the new unit, but they went out of their way to handle the permitting process for us. Even though it didn’t change anything, we appreciated their effort. I highly recommend Comfort Zone HVAC Service and will definitely keep using them!

Comfort Zone HVAC Service did an exceptional job installing a complete geothermal heating and cooling system for us. The project involved taking out an outdated boiler and outfitting an older house with ducts and vents, all carried out proficiently and in a timely manner. Zachary was our main point of contact and he did a fantastic job communicating the overarching strategy and specifics of the work. He was accommodating and addressed all our queries, offering insights from his substantial experience and knowledge. He frequently checked in to answer questions or review the work. Jacob, who was handling things in the office, promptly supplied any necessary information, clarifications, or useful leads we required. The team and subcontractors were courteous and unobtrusive while working in our home. They displayed the resourcefulness required to overcome any challenges that arose from installing a new system in an old house. Local inspectors even commended the high quality of the work done. The entire project was finished within the projected timeline, allowing us to start enjoying our system just as winter arrived, and also to qualify for rebates and tax credits. Even after the installation was completed, during a couple of extremely cold days, we kept receiving support to ensure that our system was functioning properly. We highly recommend the Water Furnace geothermal system and the excellent services of Comfort Zone HVAC Service.

Jacob from Comfort Zone HVAC Service came out to repair my air conditioning in Denver. I wanted a second opinion after being told by another company that my central AC unit needed to be replaced. Jacob arrived around 3:30 p.m. and was able to fix my unit quickly. He found the problem within 15 minutes, replaced the capacitor, and added freon since the unit had none left. After putting in the freon and new capacitor, the AC started running in less than 20 seconds. He also checked everything with his voltage meter and gauges, and added stop leak to the system. Jacob discovered that the valves and o-rings were bad and said he would order the parts and come back to finish the job. I’m very happy I called for a second opinion—my AC is working again and my house is nice and cool. Jacob was very quick to respond and fixed my issue right away.
