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.
