Mark is the greatest technician
Not sure if Tempo is the best price when it comes to maintence but they are the absolute BEST with their tech and office staff. Mark is an excellent tech and a pleasure to have in your home. He is down to earth, friendly, listens to your concerns, extremely knowledgeable, and takes his time to answer all your questions. I would not consider another company for maintaining our furnace.

Mark is great to work with , very knowledgeable about the products and is a pleasure to work with
Very happy with the installation thanks Mark! :-) I do have a comment for Chris - what is the warranty period ? you had said five years When we spoke I want to confirm that warranty period and also the cost you quoted for an Aprilaire was 475.00 including labor , not sure what model that was for but seems the price changed since we made the appointment/ would have been helpful to know that price had changed.
