Despite their importance, ducts are the most overlooked components of your HVAC system. Commercial and residential AC systems must have correctly-sized ducts to prevent issues with your equipment. The sizing of your ducts also affects your monthly utility bills.
Read on to learn more reasons why proper duct sizing matters.
What Happens If You Have Undersized Ducts?
The pressure of air will increase and back up in the system if the ducts are too small to accommodate it. This will put a strain on the blower fan, reducing the lifespan and efficiency of your HVAC system. This can result in massive stress on the components of your equipment and even lead to early breakdown.
What If You Have Oversized Ducts?
While larger ducts can handle more airflow, your HVAC system may not be designed to pump that much air. An experienced air conditioning installation technician knows that HVAC systems require a specific air pressure in the ductwork to distribute air efficiently. When the ducts are oversized, the system will work hard and restrict the amount of conditioned air that reaches your living spaces. Your HVAC system will be more prone to breakdowns, and your energy consumption will increase if your equipment works harder than it should
Factors Affecting Duct Sizing
The right size of ducts for your home or business depends on various factors, such as the size of your property, airflow velocity, the pressure of the HVAC system and friction loss. You’ll need to consider not only the size of your house but the size of every room. Cubic Feet Per Minute refers to the air velocity required to heat or cool each room in your home. Moreover, the friction loss rate of ducts lets professionals determine the static pressure for your HVAC unit throughout the ductwork’s length.
