Ensuring the Correct Size HVAC System Prior to Installation

April 22, 2020

HVAC systems are not one-size-fits-all units. To make sure that yours works as efficiently and effectively as possible in Pensacola, FL, you need the correct HVAC unit size. There are many factors to consider when sizing an HVAC system, which is why it’s best to hire a professional installer.

About Manual J Load Calculation

HVAC contractors use Manual J load calculation to determine the proper size of an HVAC system. This calculation method considers the type, size and orientation of your windows as well as how many people and appliances are in your home. The placement of your home will be factored in, as will your area’s overall climate. The amount and type of insulation that you have in your home will be assessed during the Manual J review along with the size of your home. With this information, an HVAC tech will be able to determine the proper amount of cooling capacity that will be needed for your home.

Getting the Proper HVAC System Size

Energy Star confirms that it’s important for homeowners to get an HVAC system capable of emitting the proper British Thermal Units, or BTUs. It’s easy to believe that getting an HVAC system that emits more BTUs is best regardless of the room size, but if your unit generates more BTUs than you need, you may wind up with an excessive amount of humidity in your home. This is because your system will run long enough to cool, but not long enough to dehumidify.

Consider the SEER

Many HVAC systems feature Seasonal Energy Efficiency Rating, or SEER, information. This information is an efficiency guide. The minimum rating is 13 for an air conditioner. For an HVAC unit to receive an ENERGY STAR rating, it must have a 14.5 SEER rating or higher. A higher SEER means greater efficiency.
