A small AC will try its best to cool a given area, and if the area’s too big, it will just keep on running until it does that job, which it never really does.

It will run continuously and lead to higher energy bills – Did you buy a small air conditioner because you think it will use less energy? While an AC’s capacity typically matches its energy usage, an undersized air conditioner will use more power simply because it is likely to run continuously, barely stopping for breath. The best it can probably do is cool a certain area of the house, but leave other parts warm. Your home is never cool enough – It can try as hard as it can, but an undersized AC unit is always at a disadvantage when it comes to cooling an area that is too big for it. The problem with undersized AC unitsĪC units that are too small for your home, on the other hand, present several issues as well. So you can expect to be sneezing more often and feeling sweaty and sticky in your home. Rising humidity levels and poor air quality – As we know, an oversized AC is prone to short-cycling, which means there would be extended periods where it’s turned off and therefore not doing its job of removing moisture, dust, allergens, and other particles from the air. The unit’s lifespan gets shorter – The whole short-cycling thing that happens with an oversized air conditioner inflicts a lot of wear and tear on your unit, which will eventually shorten its overall lifespan. Since big capacity AC units cool your home rather quickly, they short-cycle more often, which refers to the way an AC’s compressor turns itself on and off in rapid intervals, which is not an energy-efficient way of operating. They use more energy – Oversized air conditioners almost certainly mean higher energy bills because they take up more power to cool your home. That means from the get-go, your air conditioning costs are already high even before you get the unit installed. The upfront cost is higher – Of course, bigger air conditioners generally cost more than smaller units.

Oversized air conditioners can cause problems and cost you a lot of money in the long run. Size definitely matters when it comes to choosing an air conditioner for your home, just not in the way most people think.Ī lot of people believe that an AC with a bigger capacity is always better when it comes to cooling your home.
