I have been using them for years for my businesses, my own homes and my real estate clients’ homes. I went through five other companies before I found Luis at Protex Comfort Control. All five other companies quoted me with different prices and different problems that didn’t make any sense. Luis was the sixth person, who explained to me thoroughly the issues which didn’t cost me as much. Another event when the AC stopped working at my rental home. He helped me trouble shoot the issue when I called and he advised me to contact warranty which I did which didn’t cost me a dime to have the unit working again. He is honest, reliable, and reasonable on price. It’s hard to find a honest AC guy and I’m glad I found Luis. Highly recommend Luis and his company.
