Is bigger better when it comes to an air conditioning unit?
One of the biggest mistakes homeowners make when replacing their a/c systems is to believe bigger is better—so they buy one that's too big for their home.
When it comes to air conditioning, it's actually better to err on the side of smaller. A system that's too big for your home will leave the air feeling clammy because it won't regulate indoor humidity properly. High humidity indoors can lead to all kinds of problems—and not just with your comfort. Uncontrolled humidity can invite mold.
An air conditioning unit that's just the right size for your home will run long enough to bring your home to the temperature you like, and it will cycle the moisture out of the air. A unit that's too big for the home won't run long enough to wring out the humidity. It will cool your home too quickly, and then cut itself off before it has time to deal with the humidity. So you'll wind up with cool, clammy air.
Like driving in stop-and-go traffic, starting and stopping more frequently forces your air conditioner to run inefficiently. Even if your car gets 26 miles per gallon on the highway, it might only get 18 in the city. Likewise, a too-big air conditioning unit that cuts on and off every few minutes because it cools the house so quickly will use more energy than one that stays on long enough to do its job with the humidity. Too much on/off action also takes its toll on the equipment.
That said, you don't want to buy a unit that's too small, either. An undersized unit will run all the time without ever making your home as cool as you'd like it to be.
Let an HVAC professional determine the right size for your new air conditioning unit. You'll be more comfortable, and you'll save money and energy.
