Both Oversized And Undersized AC Units Are A Problem
When looking to install a new AC unit, size matters. It's crucial that your AC unit is sized properly for your home. Otherwise, you might wear out your new air conditioner, and you also won't have your home sufficiently cooled.
Beware of Small Units Cycling On and Off
If your AC never cycles off, it might be too small. It will constantly run while never being able to keep your home cool.
