Every Southern Arizona resident is familiar with the intense dry heat that blows through our area each and every summer. The best way to defeat these unbearable temperatures is to stay inside with the AC on. If you’re concerned about efficiency this summer, you might be wondering, “What size central air conditioner do I need in Arcadia?” 

Determining What Size AC Your Home Needs

Though there are a number of determining factors that go into choosing a central air conditioner system for your home, size is of the utmost importance. Unfortunately, central air conditioner sizing can also be complicated, making your decision a little more difficult. With these tips and tools, we hope that you can pick the system that is right for your Arcadia home.

The first thing to understand is how AC sizes are rated, which is by their cooling capacity in tons. For instance, one ton of cooling is the same as 12,000 BTU (British thermal units). The size of your home will help you determine how many tons of BTU the space needs in order to be cooled effectively.

Typically, each square foot of the home needs 20 BTU, so by using this BTU calculator, you might know what HVAC system size you need. However, there are other factors that could affect this grand total, such as how much natural light comes into the room, how many people occupy each space and if the unit is near a kitchen. By taking these factors into consideration, you could get the correctly sized unit.

What Happens When the System Is the Wrong Size?

Unfortunately, if you try to figure out on your own what size home AC unit you need, you could invest in the wrong system. If you get an AC unit that is too large, it could cool your home too rapidly and frequently, burning unnecessary energy. But if the system is too small for the space, it will consistently run to keep the temperature cool, which will also use excessive energy. This is when central air conditioner sizing can get tricky; you don’t want to get the wrong size.
