Size of AC Unit - Heating and Cooling

The size of AC unit will determine how much power it uses and ultimately, your electric bill. There are several ways to determine the appropriate size of AC unit for your home. Remember, the correct size unit will bring down your electricity costs and help you maintain the cooling system in your home. Aside from this, an oversized AC unit will short-cycle, meaning it will turn on and off frequently. Air conditioning units are typically measured in tons, and 1 ton equals 12,000 British Thermal Units.

How to Estimate the Size You Need

The most proper and scientific method for estimating the size of AC unit that you need in your home is the Manual J Load Calculation. This calculation will depend on your home’s insulation systems, the number of windows you have, and the sizes of the rooms in your home. A calculation is then based on this and the proper tons that you need will be apparent.

A rough estimate of the size you need can also be based on the comparison of your neighbors’ houses and yours. If your neighbor has the same size house as you, you can ask them what the size of their air conditioning unit is and base it from there.

You can also choose to hire a contractor to estimate the air conditioning size you need. Air conditioning professionals can give you an estimate on the size you need, while also offering installation of your air conditioning unit.

Lastly, if you are replacing an old air conditioning unit, you can check its size and base it from there. When you purchase an air conditioning unit, remember the above information so that you can save on electricity bills. You also need to find out how to maintain your AC unit, such as when you should clean the filter.
