Contrary to what many homeowners believe, the size of your air conditioner does matter!
Most importantly, the system’s energy consumption, performance quality and the resulting costs are not going to be optimal if you make the wrong choice.
What Does ‘The Right Size’ Actually Mean?
The size of an air conditioner is measured in tons. But this has nothing to do with weight. In refrigeration terms, a ton can remove 12,000 BTUs of heat per hour from the house. Therefore, a two ton AC unit can remove 24,000 BTUs in an hour.
In our previous blog, we talked about energy efficiency ratings and BTUs. The BTU or British Thermal Unit measures the cooling capacity of your AC unit. The higher the BTU level, the larger and heavier your air conditioner will be.
Residential AC units range from one to five tons, while units above five tons are usually reserved for commercial buildings. If your home needs a more powerful unit than a five-ton one, experts advise installing several smaller units and using a zoning system instead.
Why Does the AC Unit’s Size Matter?
Many homeowners believe that getting a unit larger than the one they need is a safe bet. But this is equally as bad as getting one that’s too small. You need a unit that’s just the right size!
An AC unit that’s too big for the space, will work in short but powerful cycles. While your home will cool down faster, it will heat up equally as fast. Even a highly energy-efficient unit will cost you more if it operates in such powerful and frequent cycles.
On the other hand, if a unit is too small it will keep running constantly throughout the day in order to compensate for its size. Because of that, having a smaller AC unit will also drive the electrical bill up as a result.
An air conditioner that’s just right for your home will work throughout the day, but in short, balanced cycles. As a result, you could be saving a lot of money on electricity bills without sacrificing your comfort.
