The Reasons an Oversized AC Is a Problem

blown-away

When you install a new central air conditioning system for your home, one of the most important decisions to make is the size of the AC. This doesn’t refer to its physical size, but the amount of cooling power it can provide. If an air conditioner is undersized, it won’t be able to cool the house enough to reach the target temperatures on the thermostat. 

But what about an oversized AC? That doesn’t sound so bad—having too much cooling shouldn’t be a problem. 

Unfortunately, you can’t err on the side of being too big with an AC. An oversized air conditioner will create many problems. If you plan on an air conditioning replacement in Maysville, make sure you work with professionals like ours so your AC will be the exact size it needs to be.

The Basic Trouble With an AC That’s Too Large

The reason that air conditioners cannot be oversized for the space they’re supposed to cool is because an overpowered unit will lower the temperature in the house too quickly, and this will cause the thermostat to erroneously register that the AC’s cooling cycle is complete. The air conditioner will shut off early and likely will turn back on a short time later.

The Problems From an Oversized AC

Short Cycling

When an air conditioner turns on and off frequently, it is known as short cycling. There are many different causes of this situation, but an oversized air conditioner is one of the most common. This frequent cycling puts extra wear and tear on the system, leading to a reduced lifespan and an increased likelihood of breakdowns.

Extra Strain on the AC

The constant starting and stopping put additional strain on the AC components, particularly the compressor. Oversized air conditioners often have very short life cycles because of this, and they also rack up big repair costs. 

Higher Energy Bills

An oversized AC consumes more energy because the start-up cycle is the most energy-draining part of the process. When the AC is caught short-cycling, it may turn on five to eight times an hour. This will cause cooling costs to skyrocket.

Uneven cooling

When an AC begins to short-cycle, it will not stay on long enough to cool the entire house. The center of the home will become rapidly cooled (possibly too cool!) while the more distant rooms will receive much less conditioned air. Too much cooling power means poorer comfort.

Always Rely on Professionals

There’s only one remedy to an oversized air conditioning system, and that’s to have it replaced. This time, you want to ensure that the new AC is accurately sized.
