See What Our Customers Say About Our HVAC

I scheduled my summer tune up with another big named company here in SA. I was informed that my compressor was out even tho it had been working just fine. My ac was working when the repair man left and with 1 day boom it was broken. I scheduled them to come back out this took 1 day of waiting and when the other company showed up on a Saturday they where unable to replace it fix ac like I had been informed. I got mad and told them to leave. Also, they gave me a stupid crazy quote for a 4 ton unit. I called Chester and he came out on Memorial Day! He gave me a realistic quote for a 4ton unit. My AC was replaced the very next day. The installers were amazing, courteous, neat, clean and worked their butts off all day. I highly Recommend Air Authority.
