Load Calculation: 3 Reasons Never To Install HVAC Equipment Without One

Load Calculation: 3 Reasons Never To Install HVAC Equipment Without OneYou wouldn’t put a new roof on your house without taking some very precise measurements first. Your new HVAC equipment should meet your home’s heating and cooling requirements just as precisely as your roof covers your home. That’s why it is critical for a heating and cooling professional to perform a load calculation on your home — well before you choose your new equipment.

Here are three reasons getting a load calculation early in the process will prevent headaches later:

  • A load calculation considers many contributing factors, not just your home’s size: Your home’s design, the number of windows, its number of occupants, how many heat-producing appliances you run — all are among considerations key to an accurate measure of your home’s HVAC needs. Amateurs and even some contractors apply a “rule of thumb” to determine a home’s cooling and heating load, basically considering only the home’s size. It doesn’t work.
  • Incorrectly sized heating and cooling equipment can’t do its job properly: A system that’s too big not only adds needlessly to your upfront cost, it also produces big temperature swings and fails to maintain ideal humidity levels. An undersized system struggles to meet the temperature you’ve set at the thermostat, consuming more energy than necessary even as it falls short.
  • Correctly sized systems cost less to run: Not only do oversized and undersized systems run inefficiently, wasting energy and therefore money, they are also more prone to breakdowns and early failure. That translates to higher repair and replacement costs. Correctly sized, however, heating and cooling equipment that receives regular preventive maintenance will keep your household comfortable for years — without hassles.

When you’re considering hiring an HVAC contractor to install new heating and cooling equipment, make sure they use the industry-standard Manual J method to perform your load calculation. Manual J, or Residential Load Calculation, is published by the Air Conditioning Contractors of America and is the method recommended by homeowner advocates as well as industry professionals.
