This company specializes in old air conditioners. My house in 2008 was 25 yrs old and original air conditioner. Three years later, awful noise and I called AHS, my home warranty, and they sent some other company who told me something stupid and expensive and AHS would not cover it. July: hot as hell. I called Wrich Air as I had seen their trucks in my older neighborhood. Wrich came out, told me what the noise was, told me that he buys up entire stock of parts of companies going out of business. He had EXACTLY what I needed, came while I was at work, went on the roof & replaced the part. $200. Instead of a major replacement the other guy wanted to do. So, now in 2013 I bought another 25 year old residence to be my home. Awful noise from air conditioner on roof. Called Wrich. Still great service, honest, fair price. Wrich is an expert on saving/working with what you have. He also services yearly my friends' houses with newer and double air conditioners. We all love Wrich Air!
