Last year in the middle of summer our AC went out. My husband was stressed because the cost to fix it. We finally called them and they were very polite. When the man came to check it out we told him what happened. He walked us through the problem and how to fix it. It was as simple as a switch. The best part was even though he came all the way over to check it out, they didn't charge us. I was impressed by how professional and polite he was. It is hard to find service that can compete.
