There is a lot to consider when upgrading your AC unit, including how much cooling and heating capacity it should have to keep your home at your desired temperature all year-round. You want to keep your AC unit’s overall size approximately matched to your home’s size, otherwise you could probably be wasting energy and money. If you are looking for HVAC Contractor Palo Alto, then you are at the right place.

Unfortunately, many homeowners end up purchasing an Air Conditioner unit that is big for their homes to handle. Below, we explain why oversizing your AC unit could end up being a big drawback for your home’s overall energy efficiency and comfort. To get exact sized AC for your home and offices, you can always contact HVAC Contractor East Bay.

Some of the things that can happen when your air conditioner is oversized include:

  • High humidity– As your AC cools your home, it also works to remove humidity in the home. However, an oversized Air Conditioner would not cycle properly, resulting in short cycles that are not long enough to remove humidity or cool the air. This results in a home that’s highly humid, even when the AC is running continuously.
  • Short AC lifespan– An oversized AC unit is an overworked air conditioner. Even though the cycles are shorter, the increased frequency of cycling by an oversized AC unit puts the system at high risk of damaging the compressor or other parts. Not only does a bigger unit cost more, you also would not be able to make the most of it because it will lose its efficiency out sooner than expected.
  • High energy bills– It makes sense to think that a big AC will result in a shorter cooling time. Also, the less time it takes to cool your house, the less your AC unit will run, right? Air Conditioner units run in cycles. Additionally, every time it cycles, the AC consumes more energy. An oversized AC usually short-cycle, meaning they power up and down throughout the day many times than AC units that cycle properly. This unnecessarily consumes more energy, resulting in high energy bills and lower efficiency.
