HVAC reviews in Denver, Colorado

I recently had one of my furnaces go out and had called Ultimate to come out and give me a bid. While at my home I had them check the other furnace I have in my basement. They came out and gave me a bid to do either one or both. With the new regulations on furnaces starting January 1st, I had both replaced. They kept me in the loop on when they would be at my house, and from start to finish they did an excellent job. Took less than one day to replace both of them, and when they left you would never have know they were here (the care to keep everything clean and not disturbed was great.) Everyone involved knew what they were doing, and were extremely professional.
When a furnace goes out we all know we need to get it handled quickly, and Ultimate did a great job with every aspect. I would certainly recommend them for your Heating and cooling needs.
Now looking back at this, I see they made it very easy, which . especially this time of year, is a great added benefit.

Used them for my rental property in Littleton. The ac wasn’t turning on. Their repairman Ross was quick in diagnosis and repair. The price was fair. Thank you.

Professional and honest with best prices. I should also complement their office for a fast response. I will definitely use and recommend them for all my heating and air conditioning needs.

Great experience with Denver's Best Heating and HVAC repair. Quick, timely, personable and efficient. They also diagnosed and repaired a malfunctioning trash compactor while there. Highly recommend them!

Sometimes you win and sometimes you lose, thanks to these guys I lost. I had a scheduling window from 10:00 a.m. until 2:00 p.m. and they called me at 1:30 and told me they couldn't make it because the tech's car broke down. I offered to pick up the tech and drive him to my home or pay for an Uber or Lyft... Nothing! Too bad so sad. Terrible terrible terrible company, I wouldn't use this business if it was my last resort and I hope no one else ever does. Put them out of business!!!!!

My blower fan is noisy so I called to have someone look at it to see if it needed serviced or replaced. The service tech had to reschedule since they couldn't make the original date. When he did arrived he complained that I didn't know what kind of ac I had since it's on the roof of my condo building. He said I wasn't being very helpful even though the type of ac has nothing to do with the noisy blower. When I showed him where the blower is located he complained that there wasn't much room to do any work on it. I turned on the blower and he said it sounds fine and left. $70 bucks seems a lot to have nothing done. I would not use this company again.

Were vary great full for Denvers Best we had bids from 3 other companies they beat all other bids by $2000. For our ac,furnace and hot water heater,one day for our install to .thanks

Mike, Lisa and the team are the BEST! They are thorough, and do such an amazing job- I can't recommend them enough. Customer service, professionalism and price were all unbeat. You won't regret using them!

Alec saved the day !

Denver's Best Heating and AC Repair is very responsive and very reasonably priced. I always call them for any HVAC and plumbing needs. Always professional and ready to work!

I would give a zero rating if I could. My furnace would not ignite so I called for a repairman. They sent a salesman claiming to be a repairman. Said he was pretty sure he narrowed it down to two possible issues just based on my description of it not lighting and can smell gas starting about 20 seconds of starting it up. The first one was the motor died. Well no...I said I heard the motor going. So then the only possible fix for the obvious “cracked heat exchanger” was to replace the unit. Quoted me $4500 for next day replacement. He barely even looked at the unit itself. I asked repeatedly if it could possibly be the ignition sensor since that had gone out before and was doing the same thing now that it did then. Said no absolutely not. Also said they won’t look at anything over 20 years old. Automatic replacement. Looked at the manufacture date, which is 2003. I told him it didn’t get used until 2004. He said it’s now 2019 and we can add an extra year for this and that so let’s just call it 20 year old. In desperation I hastily agreed. He said the office would call shortly and. verify the next days appointment and payment. Office called and wanted a CC number for the 50% down payment. Told her I don’t have a credit card. The only way I would have to pay was with a check. Asked for my debit card number. Told her it is not a checking account so I don’t have a card for that account. Check only. She said the install could not happen until after the check cleared. Also was baffled the “repairman”/salesman did not get any payment from me before he left. Told her he only gave me a quote and the only other payment convo was a possible payment plan. So she says “so now you want to apply for financing”. Nope never said that. Told her I wanted to cancel because this was getting WAY TO FISHY. Called another company who came out and replaced the igniter sensor and had me up and running in 30 minutes. Cost me $600. Shame on you Denver’s Best!

You know they are the worst when they have best in their name. A bunch of scammers. I had an ac system go out. I said I didn't want my whole system replaced and I just want the part fixed where it broke. The lady that answers the phone said oh we would never make you buy a whole new ac system. The repair guy came out. It was for a rental so the renters let the repair guy in. I talked to the repair guy on the phone and said that I am 10 minutes away and to wait for me before leaving. I drove 60 minutes to meet him but only had 10 more minutes to go. I get to the house and the repair guy left and didn't wait. Call him on the phone and he said that it will be $100 dollars for the investigation work which on the phone they said would be free through a promotion and $15,000 to replace my system. I said I don't want to replace my whole system. He said that the unit is over 40 years old and has to be replaced. I called someone else and they fixed it for $700. My system is 12 years old not 40 years old. I feel lied to. Also when they investigated the problem, they knocked a wire loose and then my ac system wouldn't even turn on. I am not happy with my service. The ladies on the phone are nice but the repair guys are retards and are the worst in the industry. Find someone else. The other five star reviews are fake. The real reviews are all one star. Go somewhere else for ac service. They kept calling me after it was fixed to see if I wanted to replace my system for $15,000. I told them I got it fixed for $700 and to stop calling. They kept calling wanting to replace my ac. I told them to stop harassing me. I fixed it for $700. Why would I replace it if it is running great and it is fixed for $700. My hatred for this company grows. I am not confused (their comment that I am confused). These morons can't even spell my name correct. They put me as Keis (my name is Kies) in their comment below. Guess we'll see if they actually read my comment and fix the name mistake. The person that commented from Denver's worst heating and ac is trying to look good after the scam is revealed by calling me confused. I didn't deal with the person from the company that commented below - they didn't want to fix the issue so I found someone else. Even after I repeatedly said can't you just fix the broken part. They would 't fix the broken part and only wanted to replace the entire system so I found someone else.

Techs need to be trained more, or be honest.

After inspection tech said evaporator was not in the unit. No power to it. Which was true. The coils were detached on placed on the ground.

It was suggested to get a new AC Installation ranging from $4,000-9,000. I declined. I called my landlord for help and he got someone else to look at it. He put back the evaporator inside and now my AC is fine. Always get a second opinion.

We had done a lot of research and finally decided to choose this company for our AC install, they were one of the best priced places and the reviews were good.

We were not as happy as we had hoped. We were very clear that my boyfriend worked from home and we had only a couple of windows open in which the people could come work installing the ac. The first day both people showed up late and as my boyfriend client was walking in the door so they couldn’t finish the job.

The next day when we were supposed to have ac (it’s 100 degrees outside so we’re pretty miserable) they say they will be there at 1 pm..again we were very adamant on MORNING appointments and were told it would be no problem. Well he didn’t show up, we get a call at 130 saying that he had gotten a flat tire and couldn’t come.

Now 2 weeks later, I’m having to call and get someone to come out and fix something because my AC is not working. It was installed very poorly, and now my dogs and I have to sit in a house when it’s 96 degrees outside and not have someone come look at it until 2 tomorrow.

DO NOT USE THIS COMPANY.

This is the second time I have used this company. How rare to have your call answered immediately, and have a scheduling call back sooner than expected. Merrill has come out to fix our 27 year-old furnace twice. He is often ahead of schedule and is totally knowledgeable and professional. I trust his recommendations completely. Give this company a try. True reliability is so hard to find in this field.

They’ve been great in fixing my ac in the past. I recently called to have a furnace maintenance. The scheduler was awesome and the repairman was thorough and detail oriented.

We still have some hot days ahead of us, but my furnace is ready for the winter!

The air conditioner in our tenant’s apartment wasn’t cooling. They were able to send a repair guy the same day, who replaced a capacitor in no time. The price was fair and the issue was handled quickly. Very happy with the service.

Since installing my new AC unit, the unit broke two weeks after install and has broken about 5 more times since. I have had this air conditioner for about a year and it has broken about 6 times. Every time it breaks, getting this company over here to fix it is next to impossible. Their fixes seem to be temporary. The last time they planned to come out they didn't show up at all, and Ashley (the desk clerk) relayed false information that I was unavailable to be contacted. Ive had this unit for just about a year and it hasn't worked for the majority of the hot weather this year and last year. It seems every time it breaks they give me false information about what is broken and when it will be fixed. (i.e. AJ said the condenser coil was bad but someone else from the company says its not). I wouldn't mind if it was breaking as often as it has if the company would just come out and fix it when they say they will fix it. I will be requesting a refund if this isnt fixed today.

I needed a new A/C unit installed in my commercial building and started the process of finding a company and hiring out the job late May. I found Denver's Best and was originally happy because they quoted me way less than other companies because they found a different solution that would work better for us.

Unfortunately, I can't speak to the quality of their work as they never showed up to do the job. They were on time for my estimate, but when the day came for the work to be done, there was no-call, no-show. I had to finally call them and they apologized and said they'd come the next day but same thing happened the next day. This happened 4 times in a row until finally they just stopped taking my calls/calling me back at all. The only reason I gave them 4 opportunities was because they were going to charge me way less than other companies I'd talked with but it's been nothing but a headache. Now I'm having to start the process over from the beginning again a month later and with hotter weather, no A/C, and our tech equipment in jeopardy of overheating.

I’ve used Denver’s Best Heating and AC Repair on a few occasions for my various properties. They provide extremely competent and friendly service. I have recommended this company to my neighbors as well. They are knowledgeable and fairly priced.
