We went through our home warranty company because our AC was not cooling our house. They assigned us to L & S and after I read the previous reviews I was slightly concerned. However, I decided to give them a chance. I am glad I did. The technician ended up having a cancellation so he called and was able to come early - yay! The AC was fixed within 20 minutes and has been working great ever since! Thanks L & S for the prompt service in the extreme heat of Las Vegas!
