Is Your HVAC System the Right Size for Your Home?

March 20, 2016

A load calculation is a detailed process used to properly size the heating and cooling system you’ll need to keep your Columbus, GA home comfortable for you and your family. Systems are more expensive if they’re too large, and they often shut off before dehumidifying the air, making your home feel warmer. Here’s how you can decide if your HVAC system is the right size for your home.

Use Manual J

The Air Conditioning Contractors of America created Manual J, also called Residential Load Calculation, to help with HVAC size calculations. Many contractors even have special Manual J software that considers local temperatures, the insulation in your home, the amount of shade outside, window sizes, the number of people in your family, the size of your home, and more. This is the best way to calculate the correct size for your HVAC system.

Don’t Forget About Your Ducts

After finding the right size for your system, your contractor should use Manual D, also called Residential Duct Design, to decide on sizing for your ductwork. You can make sure existing ductwork is the right size by having the airflow from the vents measured. You should also check for leaks that could lower your indoor air quality and waste energy.

Check Your Refrigerant

A professional should calibrate the amount of refrigerant in your HVAC system, also called the refrigerant charge, to prevent mechanical problems and give better efficiency. Installers add refrigerant to new systems by weight, but they must adjust the amount in existing systems by measuring pressure and temperature. They’ll need to test your system several times while adding refrigerant to make sure it gets the right amount.
