Choosing the right heat pump size

Hi, this is my first time on this forum. I live in Canada (Ottawa, Ont.) and I expect to change my heat pump this spring.

I have a 15 years old Carrier heat pump (2 tons) linked to a brand new Trane air handler (15 KW for heating, 37 000 Btu for cooling). My house is 1400 square feet. The heat pump was already there when we bought the house in the late 90's.

What ratio (tons per square feet) should I use in order to choose the right heat pump size. Should I consider the cooling capacity instead?

Thank you for responding.

ther's no reliable method using square feet only. structures vary in design, heat loss, etc. too much for that method. 2 tons sounds sufficiant. need a pro to spec a system.
i would think you would be more concerned with the heating than the cooling.
you definitly don't want to go oversize on the cooling. (mold/mildew) consider 2 speed as an option.

heatpump

barils,

i totally agree with mr. flopshot, and make sure that the system matches up this time, you could see some more $$$ in your wallet at the end of the year.
i like your quote, flopshot, wish i would have thought of it first.
