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.

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 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.

They revamped our…read moreflipped home's rather chaotic HVAC system over the past three weeks in conjunction with the City of Austin/Austin Energy rebate program for energy efficiency improvements. 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!
