How to Choose the correct size Air Conditioning Unit

An air conditioning unit is an essential element in the home that offers various heating and cooling benefits. However, it’s worth noting that every home has specific heating needs, and that’s what determines the type of AC you purchase.

Smaller units are often related to lower energy consumption, and that’s the dream of every homeowner. So, whether you’re moving to a new home or planning to change your existing system, you need to know the correct size according to your heating needs.

Factors to Consider

When choosing the right size of your air conditioner, you need to consider various factors. First, decide what type of system is suitable for your home. It could be a ductless mini-split, window unit, a portable system, or a built-in wall unit. However, no matter your choice, it’s essential that you install each unit properly.

Another thing to put in mind when purchasing the unit is the weather conditions of your location. Consider also the square footage of the room that needs heating or cooling. Note how wide the room is and the length of the ceiling.

If you have several rooms in your home, measure each separately for the best outcome. Also, take note of the direction of the sun. Rooms adjacent to the sun will heat up faster than the rest.
Don’t forget to identify the specific location to install the systems. It could be on the wall, ceiling, or window.

Another thing to consider is the size of your household and the insulation amount. Note that the air conditioning will not work well if it’s too small for the room. A larger system will cycle throughout while wasting energy, and it’ll not be able to remove humidity from the house.

Calculate Size

The actual calculation is the most challenging thing for homeowners. The AC power level is based on the number of British Thermal Units (BTUs).

To get the size, multiply the length and width of the room that needs cooling.

Once you get the total, multiply it times 25 BTU. This calculation is for the cooling needs regardless of the weather conditions. It could be on a rainy day, hot, sunny, humid, or moist day. For instance, if your room is 16ft wide and 19 feet long. Multiply 15 by 20, and the total comes to 300. So, multiply 300 by 25 BTU per each squarer foot. Whatever answer you get is the minimum BTU air conditioning required.

Remember, a smaller unit might consume more energy since it needs to run continuously to fulfill the home’s heating needs. They are also unlikely to cool the room effectively.

The Bottom Line

Getting the right calculation will help you make the appropriate choice when purchasing an AC system. Remember, an effective system needs a professional contractor like Ideal Services to help you install. If not well installed, it may not cool the rooms well since it’ll try hard to work while wasting energy. Remember that energy consumption can be too high when you don’t properly install the system or use it for more extended periods.
