The installation of new ac ducts went very smoothly and the workers cleaned up after finishing each day. I would highly recommend Green Collar to anyone needing duct replacement or repair.

The owner of the company provided our estimate, the team arrived within the time windows predicted, they were competent and courteous, and they did a *fantastic* job modernizing our system to heat quietly and evenly throughout. They added a vent to a bathroom that had been inexplicably left without one, improved the insulation throughout, and added an attic walkway for safety. We've been tolerating very uneven temps and noisy vents for the past 10 years, and I wish we would have discovered Green Collar sooner! It is *NICE* in here. I have no reservations about recommending Green Collar's services. Stay warm, y'all!

He explained to me each of the things he was doing, what he looked for in an audit, and what to expect. He also answered all of my questions about the kind of improvements that were worth it and those that were a waste of money. We were required to have an Energy Audit to sell our home and our realtor recommended Andy. Lucky for us, Andy found no recommendations and gave us a good "bill of health." What I like more is that if he does have recommendations, he doesn't perform any work himself, providing a truly unbiased opinion. I fully plan on having Andy perform an audit of our next home, whether it is required or not.

So I schedule a day for the technician to come out and service the units.. They're up there for over an hour.

Mr. Wayne followed up weeks later for quality control and added more insulation and air sealing that was even more than what we had contracted for. I can't recommend Stellrr enough!

Sorry for the long review...but please read on to hear my horror story with this sorry excuse of a company. I don't normally write reviews (good or bad), but my poor experience with this company cannot go unheard. I feel obligated to warn others of their frankly criminal business practices. I originally called them out to take a look at my old HVAC that was no longer producing cold air. They identified the Freon was low and filled it back up. Worked well for a bit, but then got low again...indicating their was a leak in the system. The unit was so old, we decided to replace the unit instead of fixing it. The new unit was installed, but not without issue. I chose what they described as their go-to brand - American Standard. Apparently their technicians do not know how to install their go-to brand, because it took several days and several different technicians to get the install completed. A year later, the unit began tripping the breaker any time it went to the 2nd stage. Took them 3 days to come out (when approaching triple digit temperatures), charged $150 service fee and $450 in parts and labor to add a capacitor to the setup (a $50 part and about 10 minutes of labor). Did not fix the problem. Tech came out again, and said it seemed to be an issue with the breaker and that I needed to call an electrician to diagnose and solve the problem. Ended up paying $300 for an electrician to come out. When he took a look at the install, he was flabbergasted. He could not believe what he was seeing! He identified the unit was installed on an aluminum electrical line, that was severely undersized for the unit installed. He said no respectable company would EVER do this kind of shotty work. He said replacing the electrical line would likely cost a couple thousand dollars, since it was on the other side of the house. When I called Smart Air to let them know of the situation, the dispatcher was very dismissive. She said she would have their lead install tech follow up with me, but of course I never heard anything back... That is when they went dark despite several additional attempts on my part, and broke communication with me entirely. I ended up having to pay an electrician to run the new line on my own dollar - several thousand dollars - and now I'm finally back up and running.
