The condenser coils in your HVAC system are located inside your outdoor air-conditioning unit. Their crucial role makes them among the most important components of an air conditioner. Let’s take a closer look at how these coils work.

How Condenser Coils Help Keep Your House Cool

Your air conditioner cools your home by taking heat from your indoor air and transferring it out of your house. The evaporator coil found inside your AC system’s indoor air handler captures heat from your home’s air and transfers it to the refrigerant. After the refrigerant absorbs the heat, it flows to your outdoor AC unit.

The refrigerant first goes to the compressor, where it’s compressed. The temperature of the refrigerant vapor rises to more than 100 degrees. After being compressed, the refrigerant flows through the condenser coil. In the coil, it converts into a liquid. In the process, the heat that the refrigerant has absorbed is released into the outside air.

After the release of the heat energy, the high-pressure liquid refrigerant flows back through the condenser coil to the evaporator coil. Before reaching the evaporator coil, it passes through the expansion valve, which helps relieve pressure from the refrigerant. That leads to the refrigerant changing back to a vaporized state so it can absorb more heat from your home.

Condenser coils play a crucial role in heat transfer, and the dirt and debris that accumulates on them over time will hinder the process and affect your comfort. Therefore, it’s crucial to keep your AC coils well maintained by scheduling preventive AC maintenance regularly.
