The Homeowner’s Guide to HVAC Parts and Their Functions

Maintaining a comfortable home environment necessitates not only the use of an efficient HVAC system but also a basic understanding of its components and their functions. Whether you are dealing with the sweltering heat of summer or the chilly winds of winter, knowing how your system works is beneficial for the long-term comfort of your household. Read on as we share a guide to the different HVAC components and how they work.

Thermostat

Serving as the command center for your HVAC system, the thermostat has a display and a set of controls that allow you to set your desired indoor temperature. Programmable thermostats, as well as those with smart features, can be programmed to meet your weekly routine, whether you’re at home for a certain period or away for another. This, in turn, helps you achieve consistent comfort while also saving substantially on energy bills.

Evaporator and Condenser Coils

Inside your air conditioner is a substance called the refrigerant, which passes through coils that are responsible for the system’s operation. The evaporator coils help cool the indoor air, while the condenser coils release the heat outdoors. The refrigerant, which passes through these coils, switches from a low-pressure liquid to a high-pressure gas and vice versa. The cycle continues until the desired temperature set on the thermostat is reached.

Compressor

Considered the “heart” of your AC system, it is the electrical component that helps the system continue the cooling cycle. It draws cool, low-pressure refrigerant gas passing through the evaporator coils, and then raises its temperature and pressure before passing through the condenser coils.

Ductwork

A central HVAC system installation won’t be complete without its network of ducts. Made of galvanized steel, aluminum or plastic, they can be rigid, flexible, or even in-between, depending on the installation requirements.
