The anatomy of an air conditioning unit can seem complex and confusing. There are a myriad of different parts that all play an important role in heating and cooling your home or business. One of the most important parts within your HVAC is the evaporator coil.
What Is It?
So what exactly is an evaporator coil? Your HVAC system’s evaporator coil plays a vital role in cooling and heating your home or business. Evaporator coils are basically the unsung heroes in the HVAC world and without them, we would all be a lot less comfortable. To put it simply, evaporator coils are indoor coils that transfer heat and send it back as cold air hold through ducts.
How Does It Work?
Evaporator coils don’t necessarily cool the air in your home—they work to take the heat from inside your home and transfer it outdoors. This transfer occurs in the evaporator coils on the inside of your HVAC system. Inside the metal coils in your AC system is coolant which evaporates and basically sinks the heat so it can move from the blower. Evaporator coils are typically made of copper—a material that heats quickly—so they can efficiently transfer heat out. You can thank these coils for keeping your home cool in the summer and warm in the winter.
How To Keep You Evaporator Coils Working Properly
Like all other parts of your HVAC system, it’s important to make sure your evaporator coils are working properly. The best way to ensure this is to make sure they’re clean. If your coils are dirty then they will be less efficient and affect the performance of your entire HVAC system. Dust and debris collect on the coils and form a layer that prevents the hot air in your house from reaching the cold metal. You can easily avoid this by using a brush and a cleaning spray to remove any dust or debris—just make sure you turn off your unit’s power before cleaning the coils!
