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.

We got bids from three local insulation and weatherization companies, and I was impressed with the comprehensive nature of Green Collar's proposal. It was itemized so that we could prioritize and chose, if we had wanted to do that.All the recommendations were clearly explained and questions answered. The actual installation was on-time, quick, and easy. Everything was done in a professional manner. We felt that we got great value and outstanding service. I would gladly recommend Green Collar to anyone looking for insulation and weatherization services.

We needed an overhaul of our ductwork. Green Collar took out all the old ducts, rebuilt the plenum, installed new ducts as well as jumpers to all of the bedrooms, they tuned and balanced the system, weatherproofed the whole house, and then blew in a bunch of new insulation. Our AC has been running less during the hottest month of the year and we couldn't be happier.
We were really impressed with their communication, the workers were wonderful, they did great work, and didn't leave a mess when they were done. Hopefully, we won't need any more HVAC work for a long time, but if and when we do, we will definitely be calling Green Collar again.

Have used them twice - problems each time. Pre-sales is great (Bill Cook), but seems they contract the work out to the lowest bidder. No quality control after they have your money.
First time - had a plenum box replaced at an old Hyde Park house. No one living there. They opened the attic access and left it open for days. When they finally showed up and replaced the plenum, they left the old in the attic along with any other trash including lunch! I called and Green Collar came out and cleaned it up. This is just a plenum replacement on a small unit!
3200 sq ft house in Dripping Springs. They completely replaced the ducts, blew in insulation, and basically redesigned air distribution (big bux!). There were immediate problems with some rooms freezing and some very hot. They sent a guy out to assess. We were told it was air distribution and was shown how to adjust the flow. There were no changes to the problem so we called again. This time we were told that we were going to be charged for a service call. After arguing with the co-owner, she agree this would be the last time for a free visit to fix. Only about a month had gone by to this point. Guy came the second time, readjusted air flow again, noticed some of the new ducts were ripped, and basically said good luck. We have lived with it for about a year thinking the new air distribution plan had flaws.
Last week we had a HVAC company show up for unrelated issues. They went into the attic an immediately saw very clinched, pinched, and misrouted ducts (see pics). They fixed and all of a sudden the rooms that were hot for a year now are cool! They explained how the restrictions on the new ducts was preventing air flow - the very reason we hired Green Collar to begin with. Someone else fixing problems that Green Collar should have easily found and rectified even before "we are finished" stage.
Bill Cook is good. After that, you are dealing with the same old don't care, let's get it done, we have their money attitude in this unregulated business. Best advice is get an estimate from Bill and then go elsewhere to get Bill's plan implemented.
