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.

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!
