The primary components include: 24 Hour Emergency Heating Service Ac Experts Near Me Commercial Hvac Service Near Me Same Day Hvac Repair 24 7 Ac Repair Near Me Heating And Ac Companies Near Me

• Blower Fan: This is the heart of the air handler, responsible for circulating air through the system. It draws air from the return ducts, passes it over the cooling or heating coils, and then distributes the conditioned air through the supply ducts.
• Heating and Cooling Coils: These coils are responsible for heating or cooling the air. Cooling coils, typically containing refrigerant, absorb heat from the air, while heating coils, often electric resistance or hot water, add heat.
• Air Filter: The air filter is a critical component for maintaining air quality. It traps dust, pollen, and other airborne particles, preventing them from circulating throughout the building and damaging the other components.
• Drain Pan and Condensate Drain: During the cooling process, condensation forms on the cooling coils. The drain pan collects this condensation, and the condensate drain removes it from the system.
• Control System: The control system, including the thermostat, regulates the operation of the air handler based on the desired temperature settings.
