HVAC System Sizing for Energy Savings and Comfort

Do any of the following sound familiar?

  • Your HVAC system is always running

  • Your HVAC system turns on and off many times throughout the day

  • It gets very humid in your home, even with the AC running

  • There are hot and cold spots throughout your house

  • You’ve had to schedule many HVAC repairs

These are all common symptoms of furnaces, air conditioners, and heat pumps that are either too big or too small for your home.

If your heating or cooling system is sized incorrectly, you’ll not only be uncomfortable, but it can also lead to a variety of mechanical issues, including added wear and tear that will shorten the lifespan of your systems and increase the frequency of breakdowns and repair calls. Proper equipment sizing is essential for home comfort, system durability, and energy efficiency, making it a high priority for any new installation project in Virginia.

Meticulous Sizing Calculation

For a heating and cooling system to properly function, it must be sized properly. Excel Heating and Cooling conducts Manual J load calculations, a protocol developed by the Air Conditioning Contractors of America (ACCA). This involves determining the heating and cooling load of a house or how much heating and cooling a home actually needs.

Making accurate load calculations takes many aspects of home design and layout into account beyond merely its square footage. The Excel team measures ceilings, floors, walls, and windows (as well as considers insulation factors) for accurate calculations.

Importance of Proper Heating and Cooling System Sizing

A new heating or cooling system is a big home investment. Accurate load and heat loss and gain calculations are important when installing a heating and cooling system on a new home or upgrading existing heating and cooling equipment.

Oversized air conditioning systems may not extract enough humidity from the air, making the home uncomfortably humid. Oversized systems turns on and off more often, which causes wear and tear and shortens the equipment life. This cycling increases energy use, driving up utility bills and degrading comfort with temperature swings. Larger HVAC systems also cost more but don’t provide an additional benefit.

Likewise, undersized HVAC systems cannot properly heat and cool, especially during winter cold snaps or Shenandoah Valley heat waves. Such systems have to run more, reducing the lifespan of the equipment and increasing your energy bill.
