When it comes to picking the right air conditioner, size is not everything. In fact, it’s estimated by the US Department of Energy that nearly 30% of American households currently have AC units that exceed their usage simply because they are not sized correctly. Although there are many reasons for this, picking the right size air conditioning is essential to maximize comfort, ensures you get the best possible value and saves money each month on utility bills. Check out the most common myths about correct air conditioning sizing below.
An air conditioning system is a precision tool designed to reduce the temperature of your home through efficient use of space. The method used by a professional HVAC contractor to determine the appropriate size for your home is just as precise and is known as completing a load calculation. A load calculation includes factoring several individual elements including:
Once the HVAC contractor has ascertained this information, they plug it into a computer to determine exactly what size of air conditioning unit will efficiently cool a home.
Another popular myth about HVAC sizing is that if you install a larger AC unit than your home needs, it will use less energy to cool the home – this is simply false. In fact, when you use a larger HVAC unit to cool a home than is recommended, the system actually works harder to achieve the desired temperature. Since the unit has a larger capacity, it will require more energy to operate effectively. And since the system will not be fine-tuned to work with the existing ductwork, the floors and other items factored in the load calculation; it will simply have to push more air into the home to achieve the desired result.
Just as we stated above, if the AC unit is not matched to achieve peak efficiency for the size of the home and all the other factors in the load calculation, it simply won’t work well. Not only that, but a smaller AC unit will have to work harder to circulate air through a home that is larger. When an AC unit has to work harder, this means it consumes more power will have the reverse effect.
When in doubt, it’s always best to trust the findings of a professional Phoenix HVAC company when you’re completing air conditioning sizing. Simply taking time to have the experts complete a load calculation could save you thousands of dollars per year in annual energy bills – as well as ensure you’re being environmentally conscious with your new AC system.
