Investing in a quality HVAC system is the best way to keep your Savannah, Georgia, home as comfortable as possible. To make sure you get the system that best matches your needs, it’s imperative you have your HVAC contractor perform a Manual J residential load calculation. Learn more about the Manual J residential load calculation and find out why it’s crucial for guaranteeing your family’s comfort.

What Is the Manual J Calculation?

The Manual J load calculation is used to determine exactly what size HVAC system you need to cool and heat your home effectively. The Air Conditioner Contractors Association of America (ACCA) has recommended that these calculations be performed whenever a new HVAC system is installed in a residential setting.

Once your heating and cooling contractor has made these load calculations, he or she can advise you as to what size system is right for your home.

How Are Manual J Calculations Performed?

How your contractor will complete your Manual J residential load calculations will depend on the layout of your home. If your house has pre-existing ductwork, for example, your contractor will perform these calculations room-by-room. For homes without ductwork, a whole house calculation can be used.

Your HVAC contractor will examine several factors while determining your load calculations:

  • Climate and weather patterns where your home is located.
  • The size of your home and how it is oriented.
  • How much insulation you have in your home and what type.
  • How much air leaks out of your home on average.

After reviewing these issues and a few others, such as your home’s windows, lighting system, and appliances, your contractor can complete your load calculations by using a piece of computer software.
