Understanding HVAC System Components and Their Functions

To make informed decisions about your HVAC system, it’s helpful to understand the function of its key components. Here’s a breakdown of the main parts and what they do:

Compressor

The compressor is the heart of your air conditioning or heat pump system. It circulates refrigerant through the system, compressing it from a low-pressure gas to a high-pressure gas. This process generates heat, which is then released outside. A faulty compressor can lead to a complete system failure, making it one of the most expensive components to repair or replace.

Condenser Coil

The condenser coil is located in the outdoor unit and is responsible for releasing heat from the refrigerant. As the hot, high-pressure refrigerant flows through the coil, it cools down and condenses into a liquid. The condenser fan helps to dissipate the heat. A dirty or damaged condenser coil can reduce the system’s efficiency and lead to overheating.

Evaporator Coil

The evaporator coil is located in the indoor unit and is responsible for absorbing heat from the air. As warm air blows across the coil, the refrigerant inside absorbs the heat and evaporates into a gas. This process cools the air, which is then circulated throughout your home. A dirty evaporator coil can reduce cooling efficiency and lead to ice buildup.

Expansion Valve

The expansion valve controls the flow of refrigerant into the evaporator coil. It reduces the pressure of the refrigerant, allowing it to evaporate and absorb heat. A malfunctioning expansion valve can cause the system to overcool or undercool, leading to discomfort and inefficiency.

Blower Motor

The blower motor circulates air through the HVAC system. It blows air across the evaporator coil to cool it in the summer and across the heat exchanger to warm it in the winter. A faulty blower motor can reduce airflow and cause the system to overheat or freeze up.

Ductwork

The ductwork is a network of channels that distributes heated or cooled air throughout your home. Properly designed and sealed ductwork is essential for efficient and effective climate control. Leaky or poorly insulated ducts can waste a significant amount of energy.
