Every single air conditioning unit includes two types of coils. You have your evaporator coil (which is also known as your indoor coil) and you have your condenser coil (also known as your outdoor coil). In this blog post we’re going to focus on your condenser coil; We’ll be answering some questions like what exactly is your condenser coil, What is its role in cooling down your home,  and why  do you have to keep it clean.

What exactly is a condenser coil?

According to www.Frigidaire.net, “the condenser coil is where the heat is removed from the refrigerant. After the gas refrigerant is pressurized and heated in the compressor, it enters the condenser coil. It is in the condenser coil that two things happen. The gas refrigerant transfers its heat to air blowing over it. Simultaneously, the refrigerant cools and turns into a liquid. The air around the coil will start to heat up and is blown out of the outdoor unit.”

In other words, with the use of a refrigerant material in the tubing, the hot air from inside your home travels outside to the condenser coils where the heat is released and removed. A huge amount of air flow is required of your air conditioner unit so the cleaner the condenser coil, the better the fan can do its job and handle all that hot air.

Your condenser coil is so important to your air conditioning unit because the entire purpose of the air conditioner is to actually remove heat from your home, it does not add cool air, like some people may think.

What are some issues caused by having a dirty condenser coil?

As stated above, your condenser coil is located outside of your home, so there’s a number of problems that can arise if your outdoor coil is dirty. For instance:

  • If you’re lacking on keeping up with the maintenance of your outdoor unit, it can very well reduce the life expectancy of your air conditioner. Manufacturers have a tendency to assume that you, as the consumer, will maintain your unit for the projected years of service.
  • Not only is the life expectancy reduced, but so is the cooling efficiency. With a dirty condenser coil your cooling efficiency will drop by over 30% leaving your system cooling at a staggering 60% or 70% effective rate.
  • Your air conditioner is no longer able to cool your home when you have a really dirty condenser unit. You’re now consuming a lot of energy while your cooling drops like a rock.

These three reasons are enough to raise awareness as to why you need to keep your outdoor unit clean. Investing in maintaining your system will prevent such problems from arising and will eventually save some of those dollar bills from jumping out of your wallet.
