What is the ideal central air condition ton size per square feet of house?

Question

is it 1 ton for every 500 square feet? so a 2000 square foot house would require a 4 ton ac?

Answer 1

Roughly. But it all depends......
It depends on how hot it gets where you are, what your house is insulated like, and the layout. The more exterior walls you have, and the more hot your climate, the more HVAC you'll need. But odds are, 4 tons is probably going to suffice. Mainly, the trick to getting good cooling is setting the thermostat, leaving it alone, and keeping the house closed up. Unless you live in desert conditions, you really only need to knock the temps back a few degrees on most days, it's the humidity you want to keep low and that's accomplished by keeping the house closed up.

Answer 3

Tons Per Square Foot

Answer 4

Most of the answers you've received thus far are somewhat incorrect.

Under normal conditions one ton (12,000 btu) of A/C will cool 500 sf of area - provided that ceilings are no higher than 8 ft. Skylights and excessive window glass might lead to a ton of A/C cooling only 400 sf. A home with few windows, or well-insulated windows, good insulation, low ceilings, and well shaded by trees could be cooled by one ton per 650 sf.

What is most important is that the unit be undersized rather than oversized. An oversized unit will cool the house too quickly and not run enough to dehumidify. An A/C must run to dehumidify the home.

Answer 5

2000 square feet is usually ok with a 2 - 2.5 ton unit BUT... if it's a bungalow, you might need much more... it really depends how well the air flows through the house via the ductwork. The airflow is determined by a combination of the fan capacity and the duct sizes as well as the run length...

Good luck!

Answer 6

Always use 400 sqft per ton youll never have a customer complain. If your taking money to the install the ac unit its easier to slow down the air flow of a unit than it is to try to cool off more of an area if its to small

Answer 7

it's roughly 1 ton for every 600 square feet. Other factors do come into play but you would need a 3.5 ton AC for a 2000 square foot house. Here is a good chart for reference on sizing of AC you would need.

Answer 9

In the description of the a/c it says how much square feet it will cool.

Answer 10

one ton of a/c covers approx.3 to 5 hundred sq feet .it depends on ceiling high, windows,age of construction.and location.[north or south]if i owned a 3bedroom bi level home in st Louis mo. approx 1900 sq feet i would install a 4 ton unit .because the newer units are more efficient but,they are less effective .all ways go 1 half ton higher then WATS expected.
