A fan coil, also known as an air handler, is a critical component in both heating and cooling systems. It’s responsible for circulating conditioned air throughout a building, making it a key player in maintaining indoor comfort. The fan coil contains a fan, evaporator or heating coil, and a filter. and at Air 1 Mechanical, we offer top-of-the-line options to enhance your comfort and energy efficiency. During the cooling process, warm air from the space is drawn over the evaporator coil, where it’s cooled and dehumidified before being recirculated as cooler air. In heating mode, the fan coil works with a heating element to warm the air before distribution. These units come in various sizes and configurations to suit different HVAC systems, offering flexibility in design and installation. Proper maintenance of fan coils is essential to ensure efficient air circulation and maintain indoor air quality in homes and buildings.
