Simon Proops from York

Came on time. Jason is very good to work with and professional. He checked the electronics and cleaned the fan outside. I would recommend High Efficiency. They are always kind and on time.

Jason was very professional and friendly, explaining the furnace technology and resolving the issue quickly. I would recommend High Efficiency for anyone looking to service their furnace or air conditioner. Thank you.

Rob was easy to deal with. He always showed up on time and his other workers were friendly and efficient. They also cleared up all the plaster dust when they were done.
