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!

Jacob and Bryan did an excellent job on my spring HVAC check-up.

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.

**1/5 Stars - Big Waste of Time (and almost a lot of money)**…read moreI wanted to like Service Wizard, but my experience with them was incredibly frustrating. My AC condensation pipe was completely backed up and needed to be flushed. Their tech arrived on time and seemed very professional, spending about an hour and a half working on the unit and inspecting everything inside and out. However, he couldn't find where the evaporator line exited the house. His solution? Install an external pump and run a whole new drain line. The rough estimate for that was, well, a hell of a lot more than the $15 fee they charged me just to come out and take a look. When he left, I still had the exact same broken AC, was stressing over an exorbitant bill to fix it, and somehow found out I'd been signed up for a $15-a-month service plan that entitled me to another check-up in six months just in time for winter. Hoping to just get it resolved, I reached out to Service Wizard via Yelp later that evening to see if they could come back today to do the work the tech recommended. I never got a response. Frustrated, I called a different AC company. They actually answered the phone, sent technicians out right on time today, and those guys spent **five minutes** at my house before finding the external line, repairing it, and flushing my system. Problem completely solved in under five minutes, and the fee was incredibly cheap compared to the massive quote I got from Service Wizard. I will definitely be canceling my $15-a-month contract with Service Wizard and won't be recommending them going forward. Save yourself the headache and call someone else!

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%.

When we noticed the building was warm this morning our Property Manager asked if we knew anyone in the Business and luckily one of our Board members mentioned Jeff. He said he was able to come by same day. He showed up early and within minutes had one of our units working after replacing a part that he had in his Truck. He then checked the other unit and had that one fixed in short order with another part. I would highly recommend his service to anyone. I am shocked at the level of service he gave us and will never call anyone else for AC Service. I wish I could say it better. He was just great.
