Air conditioners contain two types of coils. Do you know what they do?

Although air conditioners are not terribly complicated as far as machinery goes, a lot of homeowners don’t really know how the system works. Airpliance wants our customers to understand the facts, so we strive to educate people on some of the basics of how this equipment works, and the best to care for it. Let’s take a moment to talk about AC coils.

What Are AC Coils?

There are two types of coils in any air conditioner: an evaporator coil and a condenser coil. While they are called “coils,” they might not look the way you’d expect! Instead of being spiral in design, they are situated to maximize the amount of surface area exposed to air, so in actuality, they are more like lengths of metal tubes that bend back and forth along a grid.

The purpose of these two types of coils is to cool the air, and each one has a distinct job. The evaporator coil is located inside the indoor part of the unit. It contains an incredibly cold refrigerant. Air is forced over this chilled coil, and in this process the air is cooled and the refrigerant is heated.

The heated refrigerant then travels through the system to the outdoor unit. It is condensed into a hot gas in the compressor. From there, the pressurized gas goes into the condenser coil. A fan blows air over the condenser coil, absorbing heat and cooling the refrigerant gas. The hot air is then expelled outside, and the refrigerant cycles back inside to cool further and restart the process.

Airpliance is well-versed in all aspects of air conditioner repair and maintenance, so if there are any issues with how this system works, you can be sure that we’ll be able to identify it.
