Roger serviced our system today and was so professional, knowledgeable, respectful, and dignified. It was a pleasure having his help. We also have an unusual problem with what looks like a leak coming through the ceiling. Roger / Jansen have the knowledge and capabilities to find our solution! I have the utmost trust in Jansen. Three years ago we lived in a huge 1910 home without central air. Jansen took on this challenge and did it perfectly all the while keeping the duct work out of sight. They were the only company able to do that. Most HVAC businesses saw the challenges in our old home and said they weren’t able to do the job! Jansen is top notch in every way!!!
