Why an Oversized Air Conditioner is Bad for your Home

You may think that installing an oversized air conditioner may be a good idea: More power equals more cooling during the hot summer months. Unfortunately, the reverse is true when it comes to central air conditioners. If you install a cooling system that is too large for your home, you will be faced with less indoor comfort, higher energy costs and the possibility of higher repair costs to your system.

Why an Oversized Air Conditioner is Bad for your Home

  • Less Comfortable Interior Environment

An air conditioner that is too large for the space will cool your home too quickly. The air inside the house will not have the chance to mix evenly, and some spots will end up being warmer than if the system ran for a longer time.

The shorter running cycle also means that the unit’s coil doesn’t get cold enough to condense as much humidity as it would if the unit was the correct size. As a result, the inside air will feel clammy and the potential for mould and mildew growth in your home increases.

  • System Uses More Electricity

For maximum efficiency and humidity control, the air conditioner should run for at least seven minutes. If the cycle is shorter, it means your unit is using more electricity, since the load is highest when the unit starts up.

  • Possibility of Higher Repair Costs

Shorter cycles puts more stress on your air conditioner unit and as a result, may make your equipment wear out sooner. You’ll end up having to spend more on service calls because you have an oversized air conditioner installed in your home.
