To help avoid surprises and delays for your second-story addition, stay ahead of the curve by including HVAC system upgrade options for heating and cooling the new space in your design plans.
Calculate heating and cooling load
One option for heating and cooling your new addition is to simply extend the current duct system into the new space. This may seem like the logical solution, and it may very well be. However, your HVAC professional must perform a heating and cooling load assessment to determine if your current heating and cooling systems are up to the task.
Your HVAC pro should use Manual J from the Air Conditioning Contractors of America to calculate heating and cooling load. If your heating and cooling system is capable of providing ample heating and cooling for your current home and the new planned space, your HVAC pro will need to size the entire duct system using Manual D, and perhaps make modifications to existing ducts for a complete redesign and duct extension.
Upgrading your HVAC system
If you’ve determined that the best route to take is a total heating and cooling system upgrade, you’ll use the Manual J calculation to help size your new HVAC system using Manual S. It’s vital to correctly size your new heating and cooling systems, and the new duct system (retrofitted and new addition) to achieve maximum energy efficiency, and to reach peak system performance without excess workload.
HVAC system add-on
Perhaps your current heating and cooling system is still in excellent condition, but it can’t quite cover the added heating and cooling load required for the new addition. In this situation, your best solution may be adding a ductless mini split. As the name indicates, ductless mini splits don’t require ductwork, which saves money. Also, each air handler is independently controlled, providing homeowners a built-in zoning system.
