Your AC unit is one of the most important appliances in your home, and using one which may be too large or too small for the job is a common reason for an AC to fail. The problem is that people sometimes expect too much from an ordinary home AC which may be too small for the home. In this case, you have to consult an AC contractor who can determine the correct size of the unit for your home.

Why you should get the right size of an AC for your home:

In order to decrease the cost of your air conditioner, save on energy bills, and use a unit that has sufficient capacity to cool your room, you should determine the size of your cooling equipment. If the AC unit is too small, your energy bills will be higher and it will break down sooner for prolonged usage.

The AC contractor can help you a lot in knowing the right size of your AC. If your equipment is too small, you will not be satisfied with its cooling capacity. Moreover, if your unit is overworked, it will not perform as expected, and its life expectancy will be reduced. Another thing is that you’ll have high energy bills that will drain your pocket. On the other hand, if you get equipment that is too large, excess energy will just be wasted. Your unit will experience “over cycling” on high energy bills and moisture will be accumulated since your unit will not cycle properly.

How an AC contractor calculates the right size of AC unit:

• Determine the size of the space in square feet. Multiply the length and the width to get the total area. List down the number of rooms and their types.
• Calculate how much your central AC will need Btu. As an example, given an area of 1,050 square feet for your home to cool, you’ll start with a capacity of unit from 19,500 to 21,000 Btu.
• If you have rooms that are not insulated, the capacity of your AC unit should have an added 4,000 Btu for each room.

The right size of your AC unit is not that complicated, but it involves a number of variables. Since you can’t do it alone, it would be better to ask the help of an AC contractor since this kind of service is typically free anyway.
