Unlike traditional AC companies, Green Collar Operations was founded on the principle that there are many ways to conserve energy in your home than simply replacing your AC/heating system. At Green Collar Operations we believe that air balancing, duct sealing or replacement, attic insulation and attic ventilation should be explored before making the investment for new mechanical equipment. Let one of our experts pay a free visit to your home to assess your specific situation.

Usually I hold off on praising a company until I see the fruit of their labor, but I will make a rare exception here. If it proves the fruit just isn’t there, I will return. But, my first impressions of this company are solid. Bill, their estimator, came out and didn’t try to BS me into something, and believe me, my BS meter is quite acute, particularly for potentially fly by night things such as this, and mine never went off.

The good people at Green Collar did quality work at a reasonable price. They communicated with me a long the way and were ready to answer any questions I had. It is such a relief to have a reliable air conditioning system. Even after buying a new AC system, I never really saw a decrease in our bills, but once Green Collar did their work…you bet I did. Thank you everyone at Green Collar!!

We had Green Collar replace our duct work and insulation. They were courteous and on time. The price was clear up front and when extra insulation was needed, there was no additional charge. The work has proven to be well worth it. Our cooling bills last summer were 20-25% lower and our heating bills this winter have been as much as 33% less.

Green Collar installed a new AC/furnace and replaced my duct work. The workers were professional, available and easy to talk to. And so far, during the hottest time of this year, the house feels very good. They also filled out all the paperwork for City of Austin rebates and set up the inspection appointments. For that I am VERY GRATEFUL!

Brad Sage from Green Collar Operations was punctual, knowledgeable and quite patient with all my questions. He clearly explained what he was recommending and why. He also explained what work was not necessary. He handled all arrangements with the city inspector and the $500 city rebate paperwork. On top of all that, he was quite responsive via email.
