How to determine the size of AC for 2000 sq ft?
The very first step to determine the correct ac size for a 2000 sq ft house is to calculate the specific capacity required for the individual rooms. After that, you need to choose the suitable air conditioning unit depending on the required capacity. You can then decide on the type of ac that you want for the house.
What size air conditioner for a 2,000 sqft house?
As mentioned earlier, we need to calculate the cooling capacity needed for the house. The proper way of calculating the capacity is by using heat load calculations. However, the heat load calculations are very complex and often not suitable for a normal person.
Which type of air conditioner for a 2000 sqft house?
Just for residential application, there are few types of air conditioners available for you to choose from. But, don’t worry, let’s break it down into two types of air conditioners.

What size AC do I need?
Getting the right size AC unit for your house is very important if you want to have the desired level of comfort and good energy efficiency. The smallest central air conditioning unit is 18,000 BTUs (1.5 tons), while the largest is 60,000 BTUs (5 tons).
How much does it cost to install a 2.5 ton central air system?
Before we get into sizing a residential central air unit, lets take a quick look at pricing. On average, homeowners report spending $3,900 – 5,000 to install a 2.5 ton central air system in a house that has functional ductwork.
How much does a 1 ton AC unit cost?
The smallest AC unit 1 ton (12,000 BTUs) costs $1,300 – $1,700. The 1-ton units are very rarely installed as they are too small for a “CENTRAL AC” application. If you need an AC that small, you are much better off going with a ductless mini-split system.
How much tonnage is needed for a poorly insulated house?
If there is poor insulation/efficiency in your home, its best to estimate higher tonnage. In the example above, you would estimate a 4 ton unit for a poorly insulated 2,200 sq.ft. house.
What is ductless mini split?
Ductless mini split systems provide targeting cooling (and heating) to a single room or a large area. If you get a multi-zone mini split system, then you can heat and cool multiple rooms.
Why do AC systems fail?
Over 40% of all HVAC systems, including central air conditioners, fail due to incompetent, hack job installation. Especially if you are willing to spend extra money on a premium brand name AC unit, such as Carrier, don’t try to squeeze a few hundred dollars of savings by hiring a sub-par installer.

Why is it important to sizing an air conditioner?
When sizing air conditioners, be careful not to make the mistake of getting one that is too large. If the system you install is too large for the space, it will short cycle. In other words, the compressor will not run long enough to dehumidify the space and will limit your comfort. In addition, it will cycle on and off more frequently, increasing operating costs and reducing the system life. Proper air conditioner sizing is critical to optimize performance.
What determines BTU per square?
Variables such as your insulation, type and number of windows, number of stories, construction type, etc. will greatly affect the required Btu's per square for both heating and cooling. A general rule of thumb is that if your home is well insulated with newer style windows, you can select the smaller size system that falls within your total square footage.
Why do you need a 2 story home?
If your home is two story it will place less of a load on the system in the downstairs area as the second floor acts as additional insulation. If your home is not well insulated, has older style windows, and/or a larger than average number of windows, you will want to select the larger system which falls within your square footage range. The less insulated and more windows within the environment, the more likely you will experience greater air and heat loss.
When to use the lower number or higher number?
Use the lower of the two numbers if your home is well insulated and the higher number if it is older or poorly insulated. (Hint: Use the larger of the two numbers above if you're unsure of your home's insulation)

The manufacturers do not list the air conditioner size on the unit. The system capacity will be coded into the model number of the outdoor unit. For example, model GSX140241K is a 2 ton unit.
What is SEER rating?
To develop a SEER ratio, or rating, a unit’s cooling output - taken over an average cooling season - is divided by the total energy used. When less energy is used, a higher SEER ratio is earned. Keep in mind, the SEER ratio is the maximum efficiency of a unit. The most common SEER rating is 14 or 16, but American Standard Heating and Air Conditioning® offers units up to 22 SEER. Most higher SEER units have two-stage or variable cooling stages.
What is packaged air conditioner?
A packaged air conditioner system consists of a single outdoor unit. All necessary mechanical parts, like the evaporator coil, compressor, and condensing coil, are in the unit. The packaged system utilizes your home’s ductwork to cool the appropriate spaces. Based on your needs and desire for an energy-efficient unit, you can choose from single- or two-stage systems.
How is an AC rated?
Air conditioners are usually rated based on their energy efficiency and cooling capacity. As you set out to answer “what size AC unit do I need?” it’s a good idea to be familiar with how those two components are represented. A system’s energy efficiency is signified by the Seasonal Energy Efficiency Ratio (SEER), and the cooling capacity is measured in BTUh (British Thermal Units per Hour) or tons.
