The of the worst things that can happen in Texas is for your air conditioning to go out. This happened to my bro who doesn’t write reviews but I’m an eyewitness to the whole incident. My brother was referred to another company and they came out did all the checks and said he needed to replace his indoor and outdoor units. He’s been in his home for 17 years and the system was there when he bought the place. He was quoted a price for a top of the line Carrier unit and another model that Carrier manufacturers for a few hundred dollars less and he was all set to go with that until speaking with a friend who recommended A-11. It’s always good to get a second opinion because of course he would with a doctor. He called Carlos with A-11, and a few days later and he came out gave it a full check with the same result, new units in and outside. Carlos quoted the for the same Carrier unit at half the price of the first company. He said he believes it’s better to have more customers because he’s not out to get rich. He also stated they get most of their business by word of mouth. It’s so nice to do business with a company that believes in honesty. They were also very professional; they set up a time, arrived on time and completed the work within the time they quoted. An issue came up with the breakers that were installed with his previous units and his water heater. His indoor unit and his water heater were installed on the same breaker. Carlos suggest they be separated for safety(our cousin is a licensed electrician and after a confirmation call with him) my brother picked up the breakers and Carlos changed them at no additional charge. My brother’s air was running smoothly within a few hours and it looked like no one had ever been there. A job well done at a fair price.
