Hi i am dan I can help you with this. First a 3 ton system is probably big enough but it may be too big or too small. The proper way to determine that is by a whole house heat loss calculation to calculate the correct size system. This involves measuring the whole house all the windows doors and calculating the ducktwork and insulation and calculating it all in a computer program. I would be suspicious of any company that will just throw in a system that might be the right size and hope it's alright. Next why do you want lenox? In my opinion there are other manufacturers that offer better warranties and guarantees for less money and more reliable than lenox. The gimmick of trying to keep his guys busy is just that a sales gimmick. They want to try to rush you so you don't shop around and change your mind. Do not rush this at all. It is a very important decision and should not be rushed. Let me know if you have any more questions.
Did you have any other questions about this?
