Choosing the Right Size and Capacity for Your Central AC

Choosing the Right Size and Capacity for Your Central AC | Air Pros

When it is time for a new AC install in Dallas, TX, you will have many choices with cooling systems and products. At Air Pros, we suggest taking some time to fully explore your options. However, it is just as important to consider size and capacity, especially if you will be getting a central air conditioning unit. Here are some tips to help with this task.

Understanding Size and Capacity

Size does not refer to the physical size of the unit. As far as cooling products go, this is actually determined by capacity, which is measured in British Thermal Units (BTUs). This is the figure you will want to pay particular attention to when you look at the basic specifications for your central air conditioning unit.

Calculating the Size/Capacity of Your Central AC System

Size calculation is determined by multiplying the length by the width of each room or space that will need to be cooled. The total is then multiplied by 25 BTU. The number you will get will be the proper size and capacity to provide proper cooling in various situations. If you have a 12x18 room, you would get 216 square feet. Multiplying this figure by 25 BTU would then give you 5400. This means you will need a 5400 BTU capacity unit when you have our team conduct a central AC install.

What Are the Benefits of Properly Sized Air Conditioners?

Cooling capacity needs to be kept in mind since a central air conditioning system that is too small for your indoor spaces will have to work harder to achieve your ideal temperature. This extra effort increases the odds of needing AC repair and other professional attention more often.

While you may assume having a system that is too big for your home is not really such a bad thing, keep in mind that air conditioners do more than keep interior spaces cool. They also control indoor humidity levels. So, if your unit is quickly cooling your home, it may not run long enough to keep humidity levels in check. The result could be indoor spaces that feel cold and clammy – kind of like what it is like when camping on a cold, foggy night.

Other Considerations

Size is just one factor to consider with a new AC install in Dallas, TX. You will also want to consider the type of system you will be using. With central cooling units, there are two options: a packaged unit and a split system. A split system is so-named because part of the unit is outside and other components are inside. The evaporator, condenser, and compressor are all in one cabinet with a packaged cooling system.

In addition, consider how cooling levels will be controlled. For example, systems can be set up so each room is controlled by a separate thermostat.
