HVAC reviews in Greeley, Colorado

Overall I am very pleased with the experience. They were professional, had competitive pricing, and took the time to answer questions with detailed responses. They also completed the job in a timely matter. I would recommend

De Leon Heating & Air has been our go-to for over three years now, and they've been awesome! Always friendly, easy to talk to, and they show up on time. Very reliable, we wouldn't trust anyone else with our HVAC needs!

Reach out to them this morning and he was there in the afternoon, explained everything he needs to do before doing it & a fair price. Highly recommend them. Friendly professional great service

I cannot say enough good things about Welby and the quality work that he did when he installed an air conditioning system at my house! He promptly came out to my house to quote an air conditioning install after I called him and he is one of the nicest guys you will ever meet. He educated me on problems with my current heating system and gave me a very fair quote to install air conditioning. During installation of my air conditioning he addressed existing problems with my current heating/ducting and repaired them to make the system more effective and efficient. His work is top-notch and I couldn't be happier with the results. I will be recommending him to all of my friends and family!

Just had him back out to do my furnace tune up and it is running perfectly now. Thanks Welby!

Our air conditioner stopped working during some of the hottest days of summer and even though I had reached several repair businesses no one could come until the following week! De Leon’s not just responded fast, the technician came the same day and fixed the problem within the hour. He was kind, respectful and knowledgeable. My family and I were so grateful that someone with his expertise could help us in time of need! I would most definitely call on them again and highly recommend!

De Leon is a great, local family owned business. They are meticulous with repairs and installation. Very fairly priced and professional service. I highly recommend using De Leon Heating & Air!

Thank you, Welby, for such a lovely experience!
Our furnace stopped in the night and we were cold(it was in the middle of the -20's night). Someone referred DeLeon Heating to us and we called to see if he could come in the next day or so. He was out within the hour, diagnosed the problem, had the part in his van and was finished in about an hour! We are a very grateful (and warm!) family!

If you haven’t heard of De Leon Heating and Air, you need to remember them. I had the BEST experience today with an AC issue. He was able to see me quickly. He professionally inspected, diagnosed, fixed and cleaned my AC system. Pricing was so reasonable and in this day and age, that’s a miracle. I was so stressed out and now I am so relieved. Thank you again Welby De Leon.

The AC at our house completely shut down on us right at the beginning of summer.We contacted De Leon Heating & Air and Welby came out a few days later and assessed our AC unit, gave us quote and had us up and running within a few days. Initially we needed our outside compressor and coils replaced but during the process it was discovered that our furnace had some cracks in it as well. Thankfully, Welby caught the damage and was able to replace the entire unit for us at a more the reasonable cost. From the initial contact to the completion of the job Welby was straight forward, reliable, and incredibly professional.We completely recommend giving DeLeon Heating & Air a call for any heating and air concerns!

Called to get my A/C back up and running. De Leon responded promptly and was able to come fix it the next day. Very courteous and professional. Would highly recommend this small business to anyone

Highest recommendation for DeLeon Heating & Air! Welby is professional and courteous. Each time I have contacted him...he communicated well and is always pleasant. Also very prompt and reliable. The most recent visit, he was able to properly diagnose an issue with my furnace/thermostat...the result of which saved me a lot of money. I trust him completely.

They are absolutely amazing. I called so many companies To come try and fix our older unit and no one would come out unless we wanted to buy a new one. We have tried to find people to work on our unit for the air conditioning for years. Finally, the heat went out and we definitely couldn't wait in this really cold weather. We called them at 1:00 and by 2:00 they were out fixing our unit for a very reasonable price and by 3:00 they were gone and everything was done. They did what no one else would do and my family is so amazingly grateful. Thank you so much! 10 out of 10 recommend. Will continue to keep using

He was very straightforward, gave me all the information, and was willing to go over all the options and answer all our questions. He was also very thorough having caught some things that the other company had missed. And to top it off, his bid was lower than the “other guy’s.” I would recommend his service to our neighbors. I also like knowing that I’m keeping my money right here in Greeley.

My heater was being very noisy. I reached out to Welby to come and take a look at it. Turns out I needed a new blower motor. He replaced it for me for a very reasonable price. I loved his communication, knowledge and professionalism style. He kept me very well informed throughout the whole process. He even drove all the way to Arvada, CO to help me out! I will definitely be calling him in the future when needed!

AC broke last night, messaged him, I was given a time that he would be here today and he was. Very professional, interacted with my family, communicated every detail of the issue, and got my AC up and running in no time. We will definitely keep this company on speed dial. Prices are very reasonable. Thank you so much!

Welby was great! He was able to come on short notice. He explained what was going on with our AC in a way I could understand and told me what things I could be doing to help prevent another problem. He was very thorough and explained cost at each new replacement. He was professional and you could tell he truly loves his job. Overall he was able to fix our Air conditioner and get it blowing again. Thank you for your help and we will keep your contact for further assistance.

The furnace was blowing out cold air instead of hot air on 12/26/25. I called DeLeon Heating and Air and explained the problem. An hour later, Welby DeLeon showed up he was polite, and when he was done working on the furnace, hot air was coming out of the vents. Welby DeLeon is the only person who will service our furnace and air conditioner from now on.

Amazing experience! He came to do furnace check up and was wonderful. Very polite and honest. Did a detailed look at the furnace, gave us recommendations to keep it working properly. Highly recommend.

Brandon was very professional. He explained everything thoroughly. I would recommend him 1000%.

Brandon did a great job! Explained everything and had no pressure on any of his recommendations or unnecessary upselling.

Brandon Martinez did an incredible job of locating and addressing the issue with my ac unit! Truly appreciate him and your whole team for facilitating! Monica was so kind and helpful on the phone as well! Thank you greatly for rescuing me from this heatwave!
