I've been with Southwest Air Conditioning and Heating a long time. I've been in my house since 1979. And they're the only people I've dealt with as far as heating goes. I'm on my third heater. And it's working properly. They've done a good job. What I like about them is they're responsive every time I've called and needed them. I have an ongoing contract. And every year I keep renewing it. They're very courteous and professional. Scheduling is easy too. They're usually accommodating and ask me when I would like them to come out. Southwest Air Conditioning and Heating are very friendly. They're respectful in my home too. I would recommend Southwest Air Conditioning and Heating to my family and friends.
