Understanding a Basic HVAC Unit

    HVAC systems typically consist of three primary parts: the furnace or heat pump, the AC or cooling coil, and the ductwork or air distribution system. The furnace or heat pump is responsible for heating the air in the winter, while the air conditioner or cooling coil cools the air in the summer.

    The heat pump or furnace heats the air by burning fuel or using electricity, then distributes it throughout the home via ductwork. The air conditioner or cooling coil cools the air by removing heat and humidity, then circulates it through the ductwork to lower the indoor temperature. The ductwork is a network of channels that carries the conditioned air to various rooms in the home and returns it to the HVAC unit for reconditioning.

    Understanding the basic operation of your HVAC unit empowers you to troubleshoot common issues and communicate effectively with HVAC technicians. If you notice any obvious symptoms of malfunction, such as strange noises, uneven heating or cooling, or even increased energy bills, be sure to contact an HVAC contractor for professional diagnosis and repair. With regular maintenance and prompt repairs, you can enjoy reliable comfort and efficiency from your HVAC system for years to come.
