Most repairs to your air conditioning condenser unit should be handled by professionals. However, there are a few simple things that you can do to increase the efficiency of your condenser unit even if you don't have any HVAC experience. Cleaning the coils is one of the most cost effective and important maintenance tasks that the property owner can do. The great part about this job is that all you really need is a hose and some soap. This article explains the importance of cleaning condenser coils and the best technique for doing it.
What and Where Are Condenser Coils
Most people don't know what the coils are, but they have probably seen them many times. The coils are easy to see because they line the outside walls of the entire unit. The thin, aluminum sheets that you see are the coil fins. In reality, when professionals talk about cleaning the coils, they really mean cleaning the fans. This is a vital part of the system that is exposed to the elements and that can get dirty over the years. Basically, the aluminum has rows that stick out. The space between each individual row can get clogged with dust, leaves, and dirt over the years. This dramatically decreases the coil's ability to effectively transfer heat away from the fan.
How to Clean the Coils
Cleaning the coils is simple if you can reach them with a hose. Most likely, you will also need some all purpose cleaner to help break down the dirt deep in between the coils. Spray the cleaner onto the coils and let it soak in for a bit. Then, spray it out with a strong stream of water. You need to be careful to not spray with too strong of stream. Too much pressure can actually bend the coils and create a bigger problem than you began with. If you do have bent coils, you will need to invest in a coil straightening comb. These simple plastic tools are cheap and easy to use. You should clean your coils again after straightening the coils to release the dirt that was trapped.
This is obviously very simple work, so should not put it aside. The sooner and more often you clean your coils, the less likely you are to have problems with efficiency. You'll be surprised how this simple and quick clean job can actually lower your energy bills. For more information, contact a company like CNR Air Conditioning Inc.
