Only an efficient heating system, like a heat pump or furnace, will keep you and your family cozy during those bitter cold snaps. In contrast, if you're having issues with your heating system, you may have to deal with a lot of inconvenience, financial stress, and physical discomfort. The use of substandard and potentially hazardous heating equipment (space heaters, kerosene heaters, etc.).

I had four different companies out to my home for an estimate and Ultimate Heating & Cooling was the best. They are participating in the new Denver Climate Action Rebate program which saved me multiple thousands of dollars. Kyle was great at getting everything set up equipment-wise and priced out. Kelly and Ricardo did the installation and were finished in only a few hours.

I needed an A/C unit installed to cool the downstairs of my home, which I re-purposed as a short-term rental 'guest suite'. When I called in a panic after realizing the ground floor didn't have A/C, UHC had a tech (Kyle) at my house in 30 minutes to go over my options. 48 hours later, and just in time for a sweltering couple days, Sam and George were out at the house, installing the A/C. UHC customer service is top notch, and saved me a big headache with short-term rental guests. Thanks for the rush job UHC!

Ultimate Heating and Cooling installed a cooling system for us in June 2022 that involved two floor standing units and two wall mounted units in our house. Kyle, and everyone else, bent over backwards to do anything they could for us. They were great to work with and helped us to understand the equipment and the installation process. They answered all our questions, were always responsive, and really good to work with.

If everything goes perfectly, you don't always get to experience what makes an organization exceptional. Ultimate installed something we hadn't asked for, and once we realized it, they took immediate action to rectify the situation. They were genuinely apologetic and fully resolved the situation, no questions asked. I was impressed. I would strongly recommend them!

I had a great experience with Ultimate heating and cooling. Ross was very thorough and courteous in his explanation of the process and my options. William did a fantastic job installing my new hot water heater and making it up to code. Sam and George did excellent work with their installation of my AC and new thermostat and explaining it's operation to me. Thanks again guys, for a job well done. :

I would recommend Ultimate Heating & Cooling to anyone needing any HVAC work done. We wanted to get AC installed and of the 4 quote we got, Ultimate provided the most value and highest quality unit. Kyle was amazing to work with. He was professional, timely, and responsive without putting pressure on us. Sam and George did an amazing job doing the work.

They worked so hard and were so kind and clean and neat. Everyone was great and we are stoked on our system. They gave us a complimentary Ecobee thermostat and were able to add a humidifier for not very much.

Upgraded to electric only HVAC and Water Heater. No more combustion in this household, no natural gas smell, no carbon monoxide detectors. Install was beautifully done, I had little room to work with and they used every mm of space. No hassle with the rebates, product registration. Best part, is I got a year to make sure the system performs as promised. Don't hesitate to work with Justin, Ross and the team!

We had a great experience with Ultimate installing our new Furnace, A/C, and new ducting for our basement finish. From the initial call all the way to installation they were great to work with. Kyle and Justin were really helpful in walking us through all options and the scope of the job. Kelly, Sam, Jorge, and Jose then came out and did a very clean proffesional install. We are really enjoying staying comfortable with our new furnace and are looking forward to staying cool this summer.

Kyle initially worked with me to identify my new furnace options. As promised Kelly, Sam and Jorge showed up the next day to install. All three were very professional and put up with my three dogs while here. They cleaned up everything when they were done. Kelly did an excellent job of explaining my new system and showing me how it works. I would welcome them back in my home for work in the future and would recommend this company to others

Great professional team. Ultimate installed our Mitsubishi heat pump promptly and efficiently and we can't wait to have super quiet AC next summer. Not our main source of heat - but heat works well too on not overly cold days. Want to thank our whole team - Kyle as project manager and lead tech, Josh for condenser, refrigeration, thermostat programming etc. tech work, Sam and George for air handler and plenum tech work and Zar for duct system tech work.

Office administration and scheduling by Brittany very courteous and professional. Nod to Edward for permit scheduling. Last but not least, big thanks to GM Justin for keeping the whole effort running smoothly. Thank you all for making this an excellent experience. Somewhat rare these days.

We called multiple companies to repair a damaged unit that was leaking water in our home basement. After not have any success finding anyone open or willing to work on our older unit during the holidays, we were referred to UHC. They came out and promptly replaced our old system. They walked us through each step and were very professional, clean, fast, and polite. Incredibly grateful for Josh, Kelly, Will, Ricardo, Jr., and Justin. Thanks guys for all your hard work.

Kelly, Sam, Jorge, and Josh did a terrific job installing my new furnace and AC. They were very professional and efficient during the installation, and patiently answered every question we had. They are also super responsive, as it's been less than a week between my initial call to diagnose the issue and the completed installation. Highly recommend Ultimate Heating & Cooling!

The entire team at Ultimate Heating & Cooling were extremely professional, knowledgable and all around good people. Kyle provided a thorough inspection of our very old existing equipment and gave us 3 different proposals for new furnace, A/C unit and water heater. The install team, Kelly, JR and Ricardo were second to none! They did all of that work in one day.super clean and thorough. Kelly stayed much later to walk us through everything. Just Awesome all around!

My furnace failed, and the staff at Ultimate Heating & Cooling responded to my request for pricing and a site visit immediately. I got fair pricing with options before the meeting was over, and then next day my new furnace and condenser were installed. This was an emergency installation due to winter and the upcoming holidays. I cannot emphasis enough how professional Ross, Kelly, and Zar were in performing this work with skill, knowledge, courtesy, and excellent customer service! (And as a bonus they were very kind to my dog!)

Ross, of Ultimate Heating & Cooling, a real professional, thoroughly explained the benefits and pricing of new heating and AC units and related state of the art thermostats. The work was performed about 10 days later. The installers, Kelly, JR, Ricardo, Sam and Jorge arrived timely, keeping us informed prior to their arrival of their ETA. Kelly introduced the team upon their arrival and everyone entered with booties on to look at the job and answer any question before work began.

Then prep to protect our carpets with plastic walkways. It was a big job, we were told 8 hours which seemed impossible with all the demo, new install and testing. But they did it! Not only do we have new quiet, energy efficient furnances and AC units, we also have new smart thermostats. And the installers took great care of our home and left the work area cleaner than they found it.

We highly recommend Ultimate Heating & Cooling and their great professional team for new installs and for maintenance (that's where we started). They are professional, careful, nice and very thorough, explaining all before and after install including helping us with the technology to run our new system/thermostats. Thank you Ultimate!

We have used Ultimate for the past 5 years and they have been a quality partner. They are reliable, professional and provide quality services and communication at a reasonable price. Their staff is always very friendly and knowledgeable and we've had some of the same representatives come out on bids and jobs for 5 years which speaks to their employee loyalty.

Ultimate was very responsive and scheduled a quote within a few days. We had other companies tell us they didn't even know how to get new units in our 15 year old attic and egress window. Ross was confident from the beginning and was very informative regarding our options and the logistics. On the install day they came with 5 people, masked, booted and ready to get the job done. They kept us updated throughout the install discussing all options before proceeding. Would recommend for install of a new AC system!

Kelly, Junior and Ricardo did a great job installing the new furnace. They're very professional and personable. The install went smoothly and was completed in a very timely manner. Justin, who sold me the furnace, stopped by to make sure everything was going well. I'll be using UHC when the a/c needs replaced. The price is fair and the Carrier furnace is nice.

Do not use this company you will waste your time and money. Paid for them to come out and maintenance my unit. They only did half of the job. Never looked at my inside unit. When I had them come back out to finish the job they wanted to charge me more money to maintenance the inside unit. The first day they came out they should've recommended that as well but did not.

So now the second day he has found more items to charge me for. The pictures are after he said he cleaned my AC. And charged me $160 to do so. The only thing that I can see he did for $160 is use my hose to spray down the outside unit. And change my filter.

This is one of the most unprofessional companies I have ever had the displeasure of working work. Their technician (Ross) was showed up hours outside of the time frame he provided without any notification, was extremely rude, blatantly over charged me and failed to fix my air condition unit. I was told repeatedly by their operations manager (Brenda) and one of the owners that they would follow up with a resolution, weeks went by with no response from either despite numerous follow up calls by me.

When I finally spoke to the owner she was also rude and condescending. Bottom line, this company is sun by owners that have no regard for their customers, their staff lack basic communication skills and they will overcharge you with no remorse.
