What is the largest residential AC unit?

The largest residential AC system is 5 ton. There are some one story homes that need more 5 tons of cooling.

.

Just so, how many square feet will a 3 ton AC cool?

Air Conditioning Square Footage Range by Climate Zone

ZONE 1 ZONE 5
2.5 Tons 1201 - 1500 sf 1401 - 1650 sf
3 Tons 1501 - 1800 sf 1651 - 2100 sf
3.5 Tons 1801 - 2100 sf 2101 - 2300 sf
4 Tons 2101 - 2400 sf 2301 - 2700 sf

Beside above, do you need 2 AC units for a 2 story house? Generally, one area of your home will be warmer or more difficult to cool than another. In a two-story home, the upstairs area is often warmer, as warm air rises. Having two AC units in your home can help balance out the temperature. You can choose different temperatures to allow for efficiency in running the units.

People also ask, what size AC do I need for my house?

If your home is 2000 square feet, you can calculate your HVAC needs the same as you would for a 1600 square foot home. Assuming one ton of cooling capacity can cool 400 square feet of your home, you'll need about 5.0 tons of air conditioning capacity. Multiply this by 12,000 BTUs, and you'll get 60,000 BTUs.

What are the different sizes of AC units?

A standard air conditioner ranges in size, from smallest to largest:

  • 18 = 1.5 Ton (18,000 BTU)
  • 24 = 2.0 Ton (24,000 BTU)
  • 30 = 2.5 Ton (30,000 BTU)
  • 36 = 3.0 Ton (36,000 BTU)
  • 42 = 3.5 Ton (42,000 BTU)
  • 48 = 4.0 Ton (48,000 BTU)
  • 60 = 5.0 Ton (60,000 BTU)
