Video: The Importance of Properly Sized Ductwork

VACAVILLE — Host, Sarah Rutan: If you’re planning to install a new HVAC system, don’t overlook the importance of properly sized ductwork. Today we’re in Vacaville with Diamond Certified Expert Contributor Gil Medrano of All Weather Heating & Air Conditioning to learn more.

Diamond Certified Expert Contributor, Gil Medrano: When replacing your heating and cooling system, it is very important to make sure you address your ducting system, considering it is the distribution of your air flow. There are two sides to the ducting system with your heating and air conditioning. The first side is the return which is responsible for drawing air and pushing it through the machine. The second side of your ducting system is your supply side which carries the air into each individual room.

When your return ducting system is undersized, it doesn’t allow the furnace to draw in enough air flow to push through the unit and supply air into the home. You can compare this to the miles per gallon in a car. If you have a car that’s rated at 25 miles per gallon, that rating is at the speed limit. If you drive faster than the speed limit, the miles per gallon obviously drops.

Airflow is measured in CFMs. And when the airflow is down, the efficiency of your heating and cooling system is down. Not to mention the fact that it’s hard for your system to work properly when the airflow is being choked off. It’s a mechanical piece of equipment. It’s got a specific airflow design, and when that system is compromised, it causes the machine to overwork, which can create mechanical problems as well as efficiency issues. So, when replacing your heating and cooling system, it’s very important to make sure that your ductwork is properly sized so that you can achieve the efficiency that you’re looking for.
