An air handler HVAC system is a critical component of a modern home’s heating, ventilation, and air conditioning (HVAC) system. It is responsible for circulating air throughout the home and providing the necessary air quality and temperature control. The air handler is typically located in the attic or basement, and it is made up of several components, including a blower, air filter, evaporator coil, and heat exchanger. The blower is responsible for pushing air through the system, while the air filter cleans the air before it is circulated. The evaporator coil is responsible for cooling the air before it is circulated, and the heat exchanger is responsible for heating the air before it is circulated. All of these components work together to provide the necessary air quality and temperature control. The air handler is an essential part of any HVAC system, and it is important to keep it in good working order in order to ensure the system is running efficiently and effectively.
