Our Clients Love Us

"Casey, I am glad I chose your company to help with my air conditioner problem. I was a bit surprised when your workers discovered that the old duct-work was only four inches in diameter, actually, I was more depressed and concerned about how this would affect the entire job..."

Bob
"Weston called me before arriving and was on time. He was not only professional but knowledgeable. He found my problem and listened to my concerns. I will refer Weston and Welzig Heating to my family and friends..."

Celine
"Saul and his crew were all they needed to be! They did an install of a radiant heater in my airplane hangar. They did excellent work right down to making sure all caulking was effective and good looking. The system was tight and holding the applied pressure. Let's see if Excel can follow this quality act when they set the meter. Jimmy, David, Saul, et al thank you for the GREAT customer service."
