Warranty follow-up

I had a small warranty item and they were very quick to schedule appointment to come out and handle the issue. It was a very pleasant experience, David called 15 minutes before he showed up just like he said he would. He then fixed the issue in a very timely fashion. This is a new home and I wish that the other venders were as responsive and professional as David at Smith & Willis.

Jacob Loya and Jonathan Celis came to our rescue. Our builder had completely crossed the wires to the two AC units to the incorrect two furnaces. Jaco

I really appreciate the experience and professionalism that Jacob showed and his attitude to get the job done correctly --even if our builder botched the initial job. I appreciated how curteous and helpful Jacob and Jonathan were during the entire process.
