What Is an Air Handler in a House?
An air handler is a vital component of a heating, ventilation, and air conditioning (HVAC) system in a house. It is responsible for circulating conditioned air throughout the home, ensuring proper air distribution and maintaining a comfortable indoor environment. Understanding the role and functions of an air handler is crucial for homeowners to ensure efficient operation and optimal comfort levels.
An air handler consists of various components, including a blower fan, heating or cooling elements, filters, dampers, and controls. It is usually located inside the house, either in a designated mechanical room, attic, or basement. The air handler unit is connected to ductwork that distributes the conditioned air to different rooms in the house.
Functions of an Air Handler:
1. Air Circulation: The primary function of an air handler is to circulate air throughout the house, ensuring even distribution of conditioned air.
2. Temperature Control: The heating or cooling elements within the air handler help maintain the desired temperature inside the house.
3. Air Filtration: Air handlers are equipped with filters that remove dust, pollen, and other contaminants from the air, improving indoor air quality.
4. Humidity Control: Some air handlers include humidifiers or dehumidifiers, helping to regulate the moisture levels in the air.
5. Energy Efficiency: Air handlers with energy-efficient motors and components help reduce energy consumption, resulting in lower utility bills.
