Our Clients Love Us

"Outstanding service all the way around! We could not be happier with our new furnace and the Welzig Team! Casey, Jeremy, Carlos and Dave were total professionals! On time, courteous, and they know their stuff! We recommend them 100%"

Clare
"Bob came out to my house when our heater stopped working at 10 pm at night. He was cheerful despite the late hour and it was immediately obvious he knew what he was doing. He got our heat working but predicted it might not last the night due to a problem with a part. (Nothing dangerous) He promised to come back the next day. As predicted, the heat lasted a few hours and then stopped. The next day Bob was back and at work. It took several hours and replacing one part led to replacing another, but he got us back in business and the system has performed flawlessly since then. Great guy, great company and I will only use them in the future!"

Chris
"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 Xcel Energy can follow this quality act when they set the meter. Jimmy, David, Saul, et al thank you for the GREAT customer service."
