The answer to 'what does air handler do' is that an air handler is a crucial component of a central HVAC system that circulates and conditions the air throughout a home. The air handler is responsible for drawing in air from the home, filtering and conditioning it, and then pushing the treated air back out through the ductwork and vents. This helps maintain comfortable temperatures and indoor air quality.
The main functions of an air handler include:
- Blowing air through the ductwork using a powerful fan
- Cooling or heating the air using a coil that is connected to the refrigerant system or a furnace
- Filtering the air to remove dust, allergens, and other contaminants
- Controlling the humidity levels in the home by removing excess moisture
