The technician even offered information about duct cleaning which I had done a while ago with Dykstra.
Jan was very thorough with all what he did and explained every thing what he did so we understood what he was doing to keep our furnace in good working order.
Yearly cleaning of furnaces was done by Jan today. He is very knowledgeable and explained everything he was doing and why it was important. Took great care in doing a thorough job. I am confident that my furnaces are running at optimum performance after his visit.
Jan was a very pleasant technician. He was very thorough in doing his clean and check and asked if I had any questions as he went through the process. Will definitely ask for Jan again on our next appointment.
Jan was a great serviceman---he helped us ( who know nothing about furnaces) to understand more. He did a great job of the checkup!
