What is load calculation and how does it factor in to my new air conditioner?

July 07, 2016

If it’s time to think about an air conditioner replacement, having a professional perform a load calculation is important in picking the system that will work best for your home. All homes are specific in their cooling requirements. If your system is inappropriately sized, it will affect your comfort and raise your utility bills. Let’s explain what goes into a load calculation.

Historically, a load calculation was determined only by looking at the square footage of a home. That’s still one piece of the puzzle, but we include many other components to find the products that will function the best for your home. Our professionals will look at the climate in Portland, 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 find the air conditioner replacement that completes your home. If your system is very small, you’ll have issues keeping your home at the desired temperature. And just because a system is hefty doesn’t absolutely mean it’s better. Actually, if your system is too oversized for your home, you could have a lot of problems:

  • Because it won’t have to run as long, an oversized system will regularly warm up and cool down. This causes more wear and tear on the system than normal.
  • It can also decrease effectiveness 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 decent airflow. Three Rivers Heating & Cooling can help with a room-by-room load calculation. We will make sure all components of your system—your air conditioner, ductwork and registers—are working together to keep you comfortable.
