An air handler is an essential part of any air conditioning system. It is responsible for circulating air throughout the home, and it is typically composed of several different parts. The most important part of an air handler is the blower, which is responsible for pushing air through the ducts. Other parts of an air handler include the evaporator coil, which cools the air, and the condenser coil, which warms the air. Additionally, air handlers often include a filter to help remove dust and other particles from the air. All of these parts work together to provide a comfortable and efficient cooling system. Air handlers are typically located in the attic or basement of a home, and they are typically powered by electricity. It is important to regularly maintain and inspect an air handler to ensure that it is working properly and efficiently.
