Here’s Why Your Oversized AC Unit Is Less Effective: Part 2
Air conditioner units. The bigger, the better … right?
As counterintuitive as it might sound, an oversized AC unit is less effective. But what’s so bad about big a/c? To follow our previous post, here’s the second reason why you need to avoid getting an oversized a/c unit.
Cut the Wear and Tear
Every time your air conditioning unit starts up, it wears out just a little bit. And when it shuts down, it wears out a bit more. The wear is miniscule each time. But with repetition, it starts to add up.
The more your a/c starts up and shuts down, the shorter the unit’s lifespan.
If your air conditioner is oversized, it has too much “oomph.” It’s too big for the house. Like a compact car with a muscle car engine. It gets from 0-60 way too fast (or, in this case, from 79 to 78 degrees).
Because the air conditioner only has to run for a short time to reach the thermostat setpoint, it starts up and shuts down quickly. And the faster it cools the air, the less it cools your whole house (walls, floor, furniture). The cool doesn’t have time to permeate everything.
So you have cool air and a warm structure. That heat seeps into the air and collaborates with outside heat to raise the temperature quickly.
A few minutes later, the air conditioning has to turn on again. It turns on, runs for a short time, and shuts down. Again, and again, and again.
Over a full day, an oversized air conditioner will start up and shut down much more often than a right-sized air conditioner unit. The added wear and tear means you’ll likely have to repair it more often.
And you’ll have to replace it sooner.

You won’t just save on repair costs. You’ll also save the extra up-front cost of putting in a larger unit – one that’s too big.
