My newer Lennox furnace was running poorly on a Sunday. I called Hoffman and they walked me through steps to service over the phone -- at no charge!

We determined that it wasn't an emergency and that a service call could wait until Monday, saving me hundreds of dollars.

When Mike came, you could tell right away that he was a true professional. He showed me how to service my furnace for basic issues.

Thanks, guys. I'm a customer for life!
