The biggest problem with an oversized air conditioning system is that it is simply too powerful and quick at doing it’s job. In some cases, it’s comparable to using a chainsaw to trim a rose bush. Oversized air conditioning units quickly and effectively brings air temperature down to the thermostat setting, but shut off after running for just a few minutes, in a process known as “short-cycling.” That’s not ideal because cool air is just one necessary element of a comfortable home. A short-cycling AC system doesn’t have enough time to properly dehumidify the air, and high humidity isn’t ideal in all home settings.
A short-cycling system also needlessly increases your energy consumption, which can increase both your monthly energy bills and your environmental impact. Worst of all, the air conditioner will experience more wear as it frequently cycles on and off, which will mean a shorter equipment life span for your central air system. In fact, wear and tear on the cooling system can lead to expensive repairs or early replacement
It’s very important to discuss your proper AC system sizing with a professional HVAC technician. Schedule a routine service and maintenance visit to prepare for the cooling season, and ask your technician if you have a properly-sized system for your home.
