He took his time and did a wonderful job. He was consciousness about protecting our floors and cleaning up after himself. His pricing is amazing too. He never tried to upcharge us unlike some other businesses. He did a thorough clean out using the big brushes and vacuum. I highly recommend his company to anyone needing work with HVAC issues. Also he's a local small business owner which we love to support.

Our experience with Chestnut Mechanical was lovely. Our Air Conditioner stopped working during the…read more4th of July holiday weekend, and after attempting some at-home fixes and getting other estimates/diagnoses, Chestnut Mechanical was clearly the best option for us. Nick was great to work with: he showed up slightly early for both the estimate and the install, was friendly and efficient, and was able to replace the items needed to get our AC back up and running (including a new Evaporator and Condenser). Best of all, the price was 20% less expensive than other estimates we had received, and the work was completely finished within less than 48 hours of us first contacting the business (other companies wouldn't have been able to complete the repair for anywhere between one to three weeks). I would highly recommend Chestnut Mechanical for anyone in the Denver Metro region.

Audy and his team took immense pride in making sure this job was done in a reasonable time and explaining all the things that were changing with the new setup. This is my second experience with this company and I appreciate how Audy runs the team. My father didn't realize what a difference it would make getting AC in the house I grew up in when there was no AC unit. I don't have to worry that the house will get too hot for him during these Colorado heat waves. This team went above and beyond and I hope it continues on for future customers.

He also provided clear instructions on what happened and how to fix it ourselves in the future. Additionally he was not only professional and knowledgeable but also extremely friendly. Really impressed and we really appreciative him! Thank you!

I am so glad I found Halo HVAC through Yelp! My AC stopped cooling in a heat wave and I had many…read moreother companies quoting me $200++ for diagnostics or unable/unwilling to come out for weeks. I went to Yelp looking for a better option and definitely found one! Halo was able to come out within a couple days of contacting them and the diagnostic fee was $89, which was to be applied to any work performed if needed. it turned out it was a tripped breaker they were able to reset and my system is cooling perfectly again... for $89!! The most notable and appreciated factor for me is they didn't come in trying to sell me service plans, upgrades to my system or accessories, or otherwise upsell me on a well maintained and well functioning older HVAC system. Even when I asked for a quote on a heat pump to take advantage of the rebates while they last, Halo didn't push me to pick the most expensive option or upsell me on a pricier type of system. And icing on the cake - despite a lot of in and out while working on figuring things out, my technician was constantly putting on and taking off booties to keep my house clean. It's a small token of respect that goes a long way, and I very much appreciate it! I'll be using Halo and referring them to friends and family in the future!

Later on when i turned it on i realized they had installed it backwards and the supply and returns were all reversed. They were out the next day had the whole thing removed and reinstalled correctly in about 6 hours. I think this is a good company because they are fast to respond to issues and fix their mistakes. All contractors make mistakes and the good ones are the ones who fix them with minimal headaches to the customer.
