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.

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.

Vertical Heating and Cooling contacted me, via text message, saying they had received the assignment. I never heard from Vertical Heating and Cooling again. I texted Vertical Heating and Cooling and left several phone messages with no response. We could not use our dishwasher, dispoal or kitchen sink while waiting for Vertical Heating and Cooling to schedule our service. I don't know if Vertical Heating and Cooling could have completed the repairs I needed, but communication and timely customer service were not provided by Vertical Heating and Cooling. I would never recommend a company like Vertical Heating and Cooling that has no regard for customer service.

I posted a request for a service recommendation on Next Door and Cynthia from Aire Serv of the Front Range quickly responded with availability to come out to our house. Ben from Aire Serv came out within a couple hours and quickly diagnosed the issue. He went through the basics of how the unit works and what was causing the problem. Our HVAC unit hadn't been cleaned in a few years and that was causing the burners to not ignite. Ben gave me a proposal for a thorough cleaning on the spot and upon my approval got to work. Two hours later, our HVAC was back to working like a champ. Ben also gave me photos of the before and after of the cleaning. Great, thorough service and I am most grateful to Aire Serv.

Beware of those low priced furnace "tune ups" out there, IMO that just gets them in your house and then come the "problems" (speaking from experience sad to say)

Cesar is the real deal!…read more After our dryer stopped working efficiently, and I had an appliance repair company look at it, we were quoted $320 by them to clean only the dryer duct. This seemed so high to solely clear the dryer duct. I put in a project request for a whole house duct clean and Cesar responded SO FAST. He gave me a reasonable quote for the whole house including the dryer duct. 5 stars for communication throughout the whole process, from quick Yelp responses to letting me know he was on his way this morning, and for showing me photos and videos of before and after of the ducts, and just for an all around professional in-person experience. During the initial tour I asked if he also cleaned the fans in the laundry and bathrooms and he said that's not typically a part of the service, but he was happy to take a look and give them some compressed air. The before and after pics of the laundry room fan were NO JOKE. He said we might have saved that motor and I believe it. It always feels strange having a stranger move throughout the whole house, but Cesar was incredibly professional, immediately wore booties upon entering the house without me even asking, and was so gracious when we asked him to step outside a couple of times so we could move our unfriendly dog to a different floor as he moved through the space. The best part... the dryer is working flawlessly now! Hooray! I would not hesitate to recommend or hire Cesar again for any duct or HVAC needs.
