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.

I called Green Collar Operations based on their reviews and this company does not disappoint! They are very professional, provide exceptional customer service, are detailed oriented, extremely knowledgeable, and performed a great job. I had a new HVAC system put in and because I did not have a smooth, seamless experience I decided to give my business to Green Collar for duct work and add insulation. Bill Cook came to my house and conducted a full inspection. What an exemplary employee to represent the company - professional, thorough & very knowledgeable; took the time to check the work that had been done by the HVAC company and provided recommendations they had overlooked. He calmly answered all my questions, and created 2 quotes with budget options, one that included how to obtain energy rebates from the city. Bill worked it all out and help me fit in what I needed within my budget. He was prompt and returned my calls - very customer centric. Jacob & Troy came to install the insulation, performed the duct work, & replaced vents. They were respectful, meticulous and did an excellent job - they ensured everything was cleaned up and took pictures to send to the main office as part of the quality check process. Here's where the company stands out from all others: the owner of the company comes out to perform a quality inspection. That's speaks volumes and exemplifies the importance of not only exceptional customer centric practices but someone who operates with integrity, stands by the work, and leads by example. I highly recommend them.

The people who work for this company, and the work they do, are top notch. They will give you an honest assessment, a fair price, and really good service. They recently replaced my ductwork and the registers, and weatherized the house with more attic insulation and door sweeps and insulation. The house is so much more comfortable now at 80 degrees. I am beyond pleased with this company. When my HVAC unit dies, I will go with Green Collar Operations to replace it. They're the best. They're also amazing people, to a one--the kind of people you'd like to sit down and chat with. This company far exceeds expectations. This is my second weatherization experience in 10 years with Green Collar.

We've used Green Collar for several projects, this last project was a new HVAC system, repairing old ductwork, and blowing in new insulation. They were helpful, explained everything clearly, and handled our Austin Energy Rebate with little effort on our end. I highly recommend using their services.
