Great people, I would highly recommend them

Great to deal with and offered a better value than any other company I got a bid from. Absolutely would use them again!

Wonderful experience with Rob, would definitely recommend this company. I had attic insulation added.

Green Collar came out to add insulation to the attic and seal the ductwork. I thought they did an excellent job and were very professional.

This company makes fast, quick responses to ALL inquiries (not just those related to making a sale. We contacted them for a copy of our audit 9 months after they had done it. They immediately had one sent to me via email. Impressive.

I have already recommended Green Collar to several people who are interested in becoming more energy efficient in their homes. Your team was excellent!

The Green Collar team was efficient and professional from initial assessment to installation and through follow-up inspection. We can immediately tell the difference.

Had our ducts updated and sealed, and attic reinsulated. They were EXTREMELY responsive (hard to find these days) and very detailed, especially during the quoting and talking me through the whats and whys.

Great company with conscientious employees and owner. Price, communication and work performed were all fantastic! I highly recommend Green Collar for home insulation and HVAC work/services.

I am completely satisfied with the work you did for us. Communication was good from beginning to end; and the work was efficiently and professionally done. All crew members I had interactions with were friendly and engaging - and that includes Alison as well. Thank you all!

Very thorough and transparent. Will definitely call them again. The blower door test they did was super interesting. I recommend to anyone who cares about air leaks in your house.

I waited many months before the proof was available. Now it is. It's the dog days of summer. Normally the electric bill would be in the $400s. Just arrived. $277. Furthermore, the house is often too cool and I have to override the thermostat.

I can't give 100% credit. I also had to replace the main pool pump and sprung for the variable speed unit. Surely, keeping cool is the larger part of the equation.

Bill, with Green Collar Operations, is amazing. After his thorough inspection, he provided me with a list of any and all options. Some of these I could even do myself! Then, he showed me all the rebates the city would provide, which was a very nice perk.

If you have an AC that isn't doing what you want, call Bill.

The electricity bill went down on my other home $100 a month, having insulation blown in my attic changed the bill from 270 to 170 on a 1700 sq' home in August.
The best money saver I've run across ever.

I'm very happy that I wasn't sold things I didn't need. The auditor came out and we crawled around the attic to check the insulation and duct work. He didn't try to nickle and dime me or convince me I needed something I didn't. They installed a solar fan and the installation looks professional. I recommend getting a consultation from this company.

We can't say enough about the quality of the workmanship, materials and the professionalism of the workers. Rob, the owner, came by several time for quality control issues and to ensure that we were happy.

The additional blown in insulation will reap rewards for years to come. We are already telling the difference in less than a week in the comfort of our home and the acoustics. Three thumbs up for this operation with only two thumbs.

Job went very smoothly. They did what they said they would do and cleaned up after themselves. I am very happy I used them I feel confident my attic space is well insulated. I can feel the difference and the AC doesn't cycle on as frequently.

GCO performed an energy efficiency audit of our 100-year-old home. They made practical, cost-effective recommendations and didn't try to sell us anything we didn't need. We appreciate their friendly, honest service, and would hire them again.

These folks were easy to work with. I have little to no experience hiring people to do this kind of work. I had a raccoon ravage the entire attic, ruining the insulation and ductwork. Green collar showed up when they said they would, were very patient with my million questions, and helped me with paperwork I needed for my insurance company. I would recommend these for folks in a heartbeat.

Great experience, easy to work with and awesome results. Bill Cook made everything easy, and made navigating the Austin energy rebates pain free. I highly recommend these guys!
