If you live in a region where high temperatures and even higher humidity levels reign supreme throughout the summer, then getting the largest air conditioner money can buy seems to make sense. However, supersizing your A/C equipment won't always yield the best results for your home. Resisting the temptation to give your home the largest A/C system possible can be tough, so here are a few key reasons why going big could be a mistake when it comes to your home's A/C system.
The Biggest A/C System Won't Offer the Best Comfort
A common myth surrounding oversized air conditioners is that they can cool a home faster than more sensibly sized units. In reality, an oversized A/C system won't cool your home any faster than one that's properly sized for your home's cooling needs.
An oversized A/C system could also leave your home feeling cold and uncomfortably damp. A/C systems not only keep your home cool, but they also dehumidify the air in the process. Removing excess moisture plays a big role in making your home feel comfortable, but your A/C system has to run long enough to get the job done.
Oversized A/C systems usually reach their temperature set points well before they have a chance to properly dehumidify the air, resulting in a cold but damp indoor environment.
Oversized A/C Systems Can Have Short Lives
Buying an oversized A/C system also presents another problem: short cycling. Air conditioners are most efficient when they're allowed to run for long periods. A properly sized A/C system's compressor should run two to three times an hour in 10- to 15-minute increments. The compressor on an oversized A/C system, on the other hand, could cycle on and off constantly in increments as short as five minutes — hence the name "short cycling."
Short cycling does more than make it impossible to cool your home properly. The constant cycling also adds unnecessary wear and tear on your compressor and other A/C components, resulting in a short life for your A/C unit.
The Added Expense Isn't Worth the Results
Installing an oversized A/C system could also prove costly in the long run. Because oversized A/C systems often have a bigger electricity appetite, you could end up paying more in annual electricity costs than with a right-sized A/C unit. Then there's the cost of maintaining an oversized A/C system. Factor in the consequences of short cycling and you'll also pay more in repair and maintenance costs.
