Summer is in full swing and many homeowners are opting for central cooling solutions instead of relying on faulty window units or ductless units. Central AC is a great way to boost your home’s value, decrease humidity in the air, and improve air flow within your home.
However, none of these benefits will occur if the company you’ve chosen to do the install work ends up installing the wrong size central air conditioner. As we know, not all homes are the same size — and luckily not all central AC units are either! It’s important to install the correct sized unit for a variety of reasons; if the unit is too big, it will cool the house too quickly and not remove moisture in the air. If the unit is too small, it will run constantly, which means a higher utility bill and a shorter lifespan for the unit.
Factors Determining AC Unit Size
After contacting a professional central air conditioning installation company, a representative will arrive at your home and they will take the following into account:
- Your home’s location. Geographic location (latitude and longitude) has a lot to do with AC unit size. In the Northeast (specifically in the North Shore of Massachusetts) you probably won’t need as large a unit as someone in Arizona simply due to the fact that the average temperature is much cooler here.
- Cubic feet of living space. The smaller the cubic feet of living space, the smaller the central AC unit. Why pay for a larger unit when it’s not necessary to do so?
- Size and number of windows. Believe it or not, but the size and number of windows your home includes determines the size of the central air conditioning unit. The larger the windows or the more windows a home has, the more an air conditioner needs to work to cool a home during the daytime due to the sunlight filtering through. Although it can help to draw the curtains closed during the daytime, the unit will still be working harder than a house with lesser and smaller windows.
- Home’s orientation to the sun. If the majority of your windows face the southeast during the summer months here in the North Shore, then your air conditioning unit will be working much harder than one installed in a home facing northeast. During the summer, the sun rises much earlier and it’s rays come from the southeast, which means your home will warm up much quicker and the central AC unit will kick on more frequently to keep the house cool.
Air conditioning is measured by the ton and in order to calculate the exact tonnage you will need to contact a profession central AC installer. It’s important to get these numbers exact so that you aren’t spending more than you need to.
