Cord spent about 20 minutes answering my questions about how long they had been in business, how they would handle unexpected problems, and what I could expect. The owner Ron came out for the evaluation appointment and he also explained more details of the work they would perform. 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!

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.
