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!

Logistics will prevent me from hiring Austin Reliance for the work, but I'm upgrading my rating to four stars to give the benefit of the doubt to the company. Edit: Frank's excellent reply below-- taking full responsibility-- has me reconsidering. Added two stars. Original review: Not a very professional company. Frank responded to my initial Yelp request, and he came out to inspect my raccoon-damaged ducts and promised a quote. A week later, after four promises from Frank to send me a quote "shortly", no quote. Why do an onsite inspection and promise a quote if you don't intend to accept the job? My AC is out in Texas in August, and I don't appreciate being so deceptively strung along. Even without AC I'm on a budget, so I was hoping Frank's quote would be competitive and I believed every promise and kept adding another un-air-conditioned day in expectation of a price quote.

They took the time to thoroughly clean the condenser and ran multiple tests on the attic unit to make sure everything was operating as it should. What really stood out was how they walked me through the entire process at the end, showing photos and explaining each step. It gave me a lot of confidence in their work and attention to detail. I'm very happy with this company and would highly recommend them.

Good move! 1) Making maintenance appointments is easy, but it is even easier to make an appointment when there's a problem with one of our systems. They really are there for us when we need them. 2) From the moment they arrive until they depart, it's service with a smile. Check out my photo of Diego and his special carpet arrival! They keep their booties on in the house, too. 3) Our systems are running well. Poor installation problems caused by previous vendors have been corrected. 4) Pricing has been fair.
