Condenser coils, located in the outdoor unit of your HVAC system, play a crucial role in the cooling process. They help dissipate the heat absorbed from the indoor air by releasing it into the outdoor environment. Proper maintenance of condenser coils is important to ensure optimal system performance.

The blower motor is responsible for circulating the conditioned air throughout your home. It pushes the air through the air ducts and into various rooms, ensuring consistent temperature and comfort levels.

How Does an HVAC System Work?

To put it simply, an HVAC system works by extracting warm air from your home during the summer and pushing cool air in, and vice versa during the winter. It does this by utilizing refrigerant, which absorbs heat from one area and transfers it to another.

During the summer, the air conditioner removes heat from the air and blows cool air into your home. It does this by taking in warm air from inside your home, passing it over the evaporator coil where the refrigerant absorbs the heat, and then releasing the cooled air back into your living spaces.

In the winter, the furnace or heat pump absorbs heat from the outside air or the ground and transfers it into your home. It does this by using refrigerant to extract heat from the outdoor environment and then distributing it throughout your home via the air ducts.

Understanding how your HVAC system works and the role each component plays can help you troubleshoot issues, perform basic maintenance tasks, and communicate effectively with HVAC professionals when repairs or upgrades are needed.
