When should a house have two AC units?
Two units allow for an easier time balancing the desired temperature in your home. 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.
Is it better to have two small air conditioners or one large?
And if you want to cool a large, open L- or T-shaped space, you’re better off with two smaller units rather than one large one. “The goal is to keep the cold air from pooling on the floor,” explains Hank Rutkowski, director of technical affairs for the Washington, D.C.-based Air Conditioning Contractors of America.

How many square feet does a 3-ton AC unit cover?
3-ton is equal to 36,000 BTU. If you apply the 20 BTU per sq ft rule of thumb, you can see that a 3-ton air conditioner cools about 1,800 square feet spaces.
Is one AC unit enough for a two story house?
Having one AC unit for two story home can be done. You will need a dual zone AC with one unit that powers both air conditioners. Having two AC units in your home (upstairs and downstairs) can help balance out the temperature. The best option here is a mini split air conditioner.

Will 5000 BTU cool a living room?
A 5,000 Btu air conditioner can effectively cool a room that measures 100 to 150 square feet, according to a basic industry standard.
How many square feet will a 25000 BTU air conditioner cool?
1,050 to 1,600 square feet: 18,500 to 25,000 BTU.
Is 12000 Btu too much?
The most common window air conditioning units come in cooling capacities ranging from 5,000 to 12,000 Btu. A 12,000 Btu air conditioner can cool between 450 and 550 square feet of floor space. A 12,000 Btu unit could cool a room 25 feet long by 20 feet wide that has 500 square feet of floor area.

How many square feet does a 2 ton AC unit cover?
And each half-ton will cool an estimated 750 to 1,000 square feet of space.How Air Conditioner Sizes are Measured. Air Conditioner Size Home Size 2-ton unit (24,000 BTUs) 2,000 square foot home.
What size AC unit do I need for a 1800 sq ft house?
Here’s some math: You need around 20 BTUs per square foot, which is equivalent to 0.0016 tons. For example, a 600-square-foot space requires a 12,000 BTU or 1-ton unit. By those calculations, an average 1,800-square-foot house would need a 3-ton central air conditioning unit.
Can you replace a 2 ton AC unit with a 3 ton?
Simple answer: yes. But that really depends on the size of you house and its condition. If the 2 ton unit is working as designed but seems to run continuously without satisfying the thermostat setting, then it might be undersized and replacing it with a 3 ton unit might be the answer.
Is a 2 ton AC big enough?
For those of you that don’t understand the way AC systems work, a 2-ton unit typically provides cooling for about 900-1,400 square feet of space – give or take.
What is the difference between a 2 ton and 3 ton air conditioner?
HVAC experts eventually divided that number by 24 hours and came up with 12,000 BTU/1-ton AC capacity. Using that measurement, a two-ton AC unit will remove 24,000 BTUs, while a three-ton AC unit will remove 36,000 BTUs. Therefore, the more tonnage the AC unit is rated for, the more air it can cool down.
What size AC do I need for a two story house?
Pro Tip: as a rule of thumb, the maximum AC unit size you need to install should not be more than 15% more than the BTU’s you need to cool your house. This means that if your house requires a 24,000 BTU unit (2 tons), you should not install one that is larger than 30,000 BTU’s (3 tons) to maintain energy efficiency.
Is it better to put AC upstairs or downstairs?
Reduce Upstairs Heat Gain A lower cooling load in upstairs living spaces allows more moderate A/C thermostat settings and avoids over-cooling downstairs rooms. During the summer, heat energy accumulating in the attic can raise temperatures up to 150 degrees Fahrenheit.
Should my upstairs AC be set higher than downstairs?
The general rule of thumb for a two-story home is that you should set each thermostat two degrees Fahrenheit apart from the other. Then set the upstairs thermostat to a two-degree cooler setting. The extra heat downstairs will combat the cold that settles on the lower levels.
