Air Handler Knowledge
An air handler unit may resemble a furnace in appearance, but its purpose is very different. It conditions and circulates both cool and hot air, depending on what time of year it is. The system works in tandem with your air conditioner or heat pump to help get the most efficiency from your HVAC system.
How Does it Work?
The air handler is the inside component of your HVAC system, working with your split-system air conditioner or heat pump. Usually air handlers connect to existing ductwork, distributing the conditioned air through your home and returning it to the air handler. The air handler blows the air (where the heat’s been removed by the evaporator coil) through the ducts in your home.
Air Handler Sizes
Air handlers come in different sizes. Smaller units may only have an air filter, blower, and coil. These are called terminal units, blower coils, or fan coil units. A larger air handler, known as a makeup air unit, conditions 100 percent outside air; no recirculated air.
A general rule of thumb in determining whether you’ll be purchasing an air handler or not is to take a look at the temperatures where you live.
If you live in an area with mild temperatures that rarely see cooler numbers on the thermometer, you’ll most likely need an air handler. You’ll want a split-system air conditioner with an outdoor condenser and indoor air handler.
In the South, you may experience some cooler temperatures, but generally see higher ones. You’ll most likely be installing a heat pump and an air handler.
People in the North, where temperatures dip into frigidity, will want a high-efficiency gas furnace, but no air handler.
