My AC was making a weird sound and wasn't cooling. I have a warranty for this with another company and the repair tech they sent quoted me $2100 for a bad compressor. So of course I wanted a second opinion and called AHWA. Bill came out and found that it's just a dead capacitor; $205 total. The AC is now working and I'm not as grouchy. I trust AHWA and will always call them for my AC needs.
Fun Fact: I understand that their techs don't work for commission and don't "upsell" customers; they are paid a fair wage and are not overworked.
