The Difference Between Evaporator Coil & Condenser Coil

In your air conditioner, the condenser and evaporator coils play a crucial role in cooling and evaporating the air. Regarding AC care and maintenance, it’s critical to comprehend the function.

About Your Cooling System

Your home’s interior heat is removed via your cooling system, which may be your central air conditioner. To finish the chilling process, this unit will use its refrigerant to transition from a liquid state to a gas state and back to a liquid state. The transmission of the refrigerant depends heavily on the performance of the condenser and evaporator coils.

Beyond just their relative positions in the system, condenser and evaporator coils differ from one another. When an air conditioner fails to deliver the desired level of comfort, many homeowners assume that the internal coolness generator must have malfunctioned and immediately believe they need an air conditioner repair. Because there isn’t a component like that, the problem can be resolved quickly. Instead of producing cooling, air conditioners can transport heat. An air conditioner’s ability to keep your home cool is just a byproduct of efficient heat transmission.

The Evaporator Coil

The main purpose of the evaporator coil is to transfer indoor heat from the air into the refrigerant. The evaporator, which is fixed inside the inner air director, is frequently exposed to the warm air transfer from various rooms in the house through the back duct by the sweeper system. Refrigerant circulates through the coil as a chilly vapor at roughly 40 degrees through copper tubes. In this condition, the refrigerant’s capacity to soak up heat is at its highest.

Through the copper coil, you may transfer heat energy from a warm house, and the refrigerant flow can quickly absorb it. The blower distributes the cooling airflow throughout the house through the ductwork while the coil absorbs its heat. Condensation begins as hot air moves toward the evaporator coil’s frozen surface, removing heat simultaneously. The process of condensation reduces the humidity in the airflow.

The Condenser Coil

The condenser coil is constructed similarly to an indoor evaporator coil. The condenser coil and evaporator differ entirely in opposite ways. The heat is transferred to the evaporator coil from the inside air. Heat is released into the open air by the condenser coil. When the heated refrigerant goes into the coil and turns into liquid, the high amount of heat that has been trapped inside the house is immediately released. The condenser coil releases a lot of heat into the surrounding air as the air is blown through it by a fan integrated within the unit. When the liquid is under extreme pressure, it exits the condenser coil, turns around, and moves back to the evaporator coil. 

Care for coils

Evaporator and condenser coils are both subject to the necessity to plan annual coordination by a licensed HVAC contractor. It is a crucial component of operating your air conditioner in accordance with the producer’s performance and organization requirements. Their various roles and placements have an impact on the need for separate maintenance for each coil.

Issues with Evaporator Coils

The blower’s airflow frequently exposes the evaporator coil, making it vulnerable to spreading dust and filth. The efficiency of heat transferred from the air to the refrigerant is decreased when an airborne component layer forms on the coil’s surface. The cooling procedure then has very poor results. Another element that is certain to affect the evaporator coil is mold infection.

One of the minuscule elements that travel through the HVAC airflow system is dormant mold spores. When moisture is present, resting mold spores become active growers as soon as they come into contact with a coil surface that has been dampened by condensation. The coil’s mold growth could completely obstruct airflow at the very end, causing the system to crash. If you have any issues, please get in touch with us.
