View full detailsAn air handler is a crucial component of an HVAC system that is responsible for circulating and conditioning air. It houses components such as the blower motor, evaporator coil, and air filter. The air handler distributes conditioned air (heated or cooled) through the ductwork to various parts of the building and returns air back to the HVAC system to be reconditioned.
Another name for an air handler is an "air handling unit" (AHU). It is sometimes also referred to as a "fan coil unit" in certain contexts, although fan coil units are typically smaller and used for specific zones or rooms.
Yes, you can replace just the air handler if it is malfunctioning or outdated. However, it is important to ensure that the new air handler is compatible with your existing HVAC system, including the outdoor condenser unit. Consulting with an HVAC professional is recommended to ensure proper sizing, compatibility, and installation.
The air handler's job is to circulate and condition air within the building. It does this by: Housing the blower motor that pushes air through the ductwork. Containing the evaporator coil where the refrigerant absorbs heat from the indoor air (in cooling mode). Filtering the air to remove dust, allergens, and other particles. Sometimes including heating elements to provide warm air (in heating mode).
Generally, the air handler does not pull air directly from outside. Instead, it recirculates indoor air through the HVAC system. However, some systems may have a fresh air intake to bring in a small amount of outside air for ventilation purposes. This feature helps improve indoor air quality by diluting indoor pollutants with fresh outdoor air.
Whether you should leave your air handler on all the time depends on your specific needs and preferences. Running the air handler continuously can help maintain consistent indoor air quality and temperature, and may be beneficial in humid climates to control humidity levels. However, it can also lead to higher energy consumption. Many modern thermostats offer settings like "Auto" and "Fan On" to help manage when the air handler operates. The "Auto" setting typically runs the air handler only when heating or cooling is needed, while the "Fan On" setting keeps it running continuously.
Not all houses have an air handler. Air handlers are typically found in homes with central HVAC systems, including forced air heating and cooling systems. Some homes may use alternative systems such as ductless mini-split systems, radiant heating, or window air conditioners, which do not require a traditional air handler. The type of HVAC system installed in a home will determine whether an air handler is used.
