How big of an AC unit do I need for a 1600 sq ft house?

Assuming the minimum cooling capacity of 400 square feet per ton for your HVAC unit, a 1600 square foot home will require 4.0 tons of air conditioning to cool. Your HVAC unit will need to remove about 4.0 x 12,000 BTUs, or 48,000 BTUs, per hour to keep your home cool.

How big of an AC unit do I need for 1, 500 sq ft?

To properly get the tonnage of the AC you need, you can use the AC tonnage calculator here: For example, a standard 1,500 sq ft house would need a 2.5-ton air conditioner. To help us out, here is a quick table showing how many tons (and BTU) air conditioners we need for certain square footage:

How is an air conditioner measured for a house?

Sizing an air conditioning unit to a house is a matter of calculating the square footage, converting the square footage to British thermal units (BTUs), and adjusting for specific rooms. BTUs is a type of measurement used to determine the amount of energy to heat a space.

How much air conditioner tonnage per square foot?

According to the DOE, “…an air conditioner generally needs 20 BTU for each square foot of living space.” We need to convert BTU to tonnage. 1 ton equals 12,000 BTU. That means that, on average, we will need 0.0016 tons per square foot.
