They are very responsive, very professional and very transparent with what they are doing and why. They would never charge for services that aren't needed and are extremely considerate and kind.

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.

They were great to…read morework with, doing a thorough measurement of the house to figure out the correct system size and giving me lots of options to choose between. The installation went great - after having a bad experience with a new hvac system at my old house on the east coast, these guys clearly knew what they were doing and everything looked and worked great when they were done. Thus far the system has done a bang-up job, with no problems keeping the set temperatures between the 0-degree days last winter or the high-90s days this summer. And the high-efficiency system means my gas and electric usage have gone way down, compared to the usage of the old system.

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.
