What is load calculation and how does it factor in to my new air conditioner?07/07/2016 If it’s time to think about an air conditioner replacement, having a technician perform a load calculation is crucial in choosing the system that will work best for your living space. All homes are different in their cooling requirements. If your system is improperly sized, it will affect your comfort and increase your utility bills. Let’s explain what goes into a load calculation. Historically, a load calculation was conducted only by looking at the square footage of a home. That’s still one piece of the puzzle, but we regard various other factors to find the products that will be the best for your home. Our experts will look at the climate in the Main Line, the square footage and design of your home, the level of insulation, your roof size and type, the size and location of windows, your home’s sun exposure and your family’s habits and schedule. We aim to help you come across the air conditioner replacement that completes your home. If your system is very small, you’ll have difficulty keeping your home at the ideal temperature. And just because a system is larger doesn’t absolutely mean it’s better. In reality, if your system is too oversized for your home, you could have a lot of problems: Because it won’t have to function as long, an oversized system will regularly warm up and cool down. This creates more wear and tear on the system than need-be. It can also minimize efficiency and raise utility bills. Another problem with an oversized system cycling on and off too much is it will fail to dehumidify your air properly. One key to your home’s comfort is ensuring proper airflow.
