Size matters when you’re buying a new air conditioner. Both oversized and undersized air conditioners are more expensive to run than properly sized systems, and they have a harder time cooling your home. Luckily, choosing a correctly sized AC unit isn’t hard. With a little research and professional advice, you can easily pick out the perfect unit for your Dacula, Georgia, home.

Before you invest in a new AC, keep reading to learn why air conditioner size matters.


Not surprisingly, an undersized air conditioner will struggle to cool your home. It’ll run longer cycles than it should since the square footage it’s trying to cool is simply too large for its output capacity.

On the other hand, an oversized unit will short cycle, meaning it’ll turn on and off in short bursts. Short cycling brings temperatures down too quickly. While this might not sound like a problem, short cycles don’t give your unit enough time to effectively dehumidify your home and can leave you feeling clammy.


Air conditioners that are too small run for too long trying to reach your set temperature. Long cycles put undue stress on AC units, which can cause them to break down and ultimately shorten their life span.

Since oversized units short cycle, they experience a tremendous amount of extra wear and tear over time. This frequent cycling also contributes to energy waste and simply wears out the unit, which can cause it to fail prematurely.


An incorrectly sized unit has big financial ramifications. A system that’s too big or small for your home is more expensive to run and will require replacement before a correctly sized unit will. Due to extra wear and tear, it’s likely to require more upkeep and maintenance, as well.
