I've been using Southwest Air Conditioning and Heating since the early nineties. They installed the original unit in my house. Since then, two more air conditioning units have been installed by them. I came to know the guys pretty well over the years and used to bump into the main guy in town at places like the grocery store. He was always personable and we would chat for a few minutes. Anytime I needed something, I'd give him a call and he'd come to take care of it, no questions asked. Now they have some new techs in the company who I have come to rely on. We just recently had more than two weeks of triple-digit heat here in Abilene, and the air conditioner has been working hard. First, I had some kind of electrical problem with a switch. Then a few weeks ago, the condensation line got so clogged from the humidity I couldn't clear it myself. So I called Southwest and they sent someone out to clear it for me. The techs from Southwest Air Conditioning and Heating have always been very professional. They try to please the customer. That's what I appreciate. I could use someone cheaper but the techs from Southwest always know what they are doing, address the problem, and take care of it. I've been very happy with their service all these years.
