Angel and his team replaced the old fiberglass insulation in my attic with cellulose, air-sealed my attic, and insulated my catwalk. They were on-time, communicative, and did great work. I was impressed every step of the way. They also went above and beyond, adding extra insulation at no charge! 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! This isn't a paid promotion or anything, I just think more people should contract with Stellrr and want to let people know that my experience with them was phenomenal. I recommend them 100%.

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!
