What is Forced Air?
A forced air system is a heating or cooling system that pushes air through ducts to raise or lower the temperature in a home. Forced air is the term that usually refers to the system’s heating features. The term central air can refer to the cooling capabilities of the very same system.
In the context of heating, the most common forced air system is the standard furnace. The furnace delivers hot air into the system, which is then distributed all through the home via ducts and vents. Most homes here in Canada have a system like this for winter heating.
How Can I Make Forced Air More Efficient?
There are several ways to raise the efficiency of your forced air system:
Clean or Change Your Furnace Filters Regularly
Many systems have filters that are either replaceable or cleanable. These filters sit at key points in the system and help keep particulate matter from polluting indoor air. At a certain point, it is no longer possible for the filters to take on any more debris, inhibiting the flow of air. The user manual of your forced air system will provide a schedule for changing your filters.
Upgrade Your Thermostat
Your thermostat is the “brain” of your forced air system, letting it know when to turn on and off and how long to run. Over time, thermostats can lose their ability to interpret signals from the temperature sensors. The system may run too long or not run long enough. It may also cycle on and off, drawing lots of power. A programmable electronic thermostat is the most efficient pick.
Get Annual System Maintenance
Annual maintenance from professionals is an important part of keeping your system working at peak efficiency. There are many maintenance tasks that can only be performed by experts. This includes specialty cleaning of the furnace to remove waste. The buildup of waste products in an under-maintained furnace is one of the biggest contributors to fire risk.
Encourage Appropriate Airflow
Your whole home contributes to efficient airflow throughout your rooms. To help air flow more effectively, keep your system’s registers opened wide at all times. Use fans, especially ceiling fans, blowing at a low level to help distribute air. Keep the area around the furnace itself clean and clear of obstruction and replace any windows that become warped.
