In 2011 I bought a home in Northwest Harris County that had 25 year old A/C and Heating components. Gary came out to my house shortly after moving in to give me a quote on upgrading these components even though they were in working order at the time. Since I had just bought the house and it needed some other upgrades, I decided not to upgrade the A/C and Heating at that time. In 2012 the furnace went out and Gary came out to replace it. He did a great job and charged a fair price. In 2013 I called him back to finally replace my A/C which again he installed quickly and at a fair price. His service is top notch, he is knowledgable and his estimates were below all other contractors I called. Even after 3 years of calling him about replacements he never ignored my call, took longer than a day to get back to me, or refused to come out to promptly service my aged components. I would refer him to all my friends, family, and co-workers. Thank you!
