The Importance of Cleaning Outdoor Air Conditioning Coils

Air conditioning units are essential for keeping commercial buildings cool and comfortable during the hot summer months. However, over time, the outdoor coils of these units can become dirty and clogged with dirt, dust, pollen, and other debris. This can lead to a number of problems, including:

  • Reduced efficiency: When the coils are dirty, they cannot transfer heat as effectively, which can lead to your air conditioner working harder and using more energy. This can increase your energy bills by up to 20%.
  • Shortened lifespan: The coils are an important part of your air conditioner, and if they are not properly maintained, they can wear out prematurely. This can lead to costly repairs or even the need to replace your entire unit.
  • Poor indoor air quality: The dirty coils can also become a breeding ground for bacteria and mold, which can release harmful allergens into the air. This can cause respiratory problems for people with allergies or asthma.

To prevent these problems, it is important to clean the outdoor coils of your air conditioning unit on a regular basis. The frequency of cleaning will depend on the environment in which your unit is located. In areas with a lot of dust and pollen, you may need to clean the coils more often.

Different ways to clean outdoor air conditioning coils.

You can do it yourself, or you can hire a professional. If you choose to do it yourself, there are a few things you will need:

  • A garden hose
  • A mild detergent
  • A brush
  • A ladder

First, disconnect the power to the air conditioner. Then, use the garden hose to rinse off the coils. Be careful not to spray too much water directly onto the unit, as this can damage the electrical components.

Next, mix the mild detergent with water and apply it to the coils with the brush. Be sure to scrub all of the dirt and debris away.

Finally, rinse the coils again with the garden hose and dry them with a towel.

If you are not comfortable cleaning the coils yourself, you can hire a professional to do it for you. This is the best option if you have a large unit or if the coils are very dirty.

Regularly cleaning the outdoor coils of your air conditioning unit is an important way to keep your unit running efficiently and prevent costly repairs. It is also a good way to improve the indoor air quality in your building.

In addition to cleaning the coils, there are a few other things you can do to keep your air conditioning unit running properly:

  • Change the air filter regularly.
  • Have the unit serviced by a qualified technician once a year.
  • Keep the unit clear of debris and obstructions.

By following these simple tips, you can help extend the life of your air conditioning unit and keep your building cool and comfortable all summer long.

Additional benefits of cleaning outdoor air conditioning coils:

  • Reduced noise: When the coils are clean, they can operate more efficiently, which can lead to reduced noise levels.
  • Increased lifespan of other components: The condenser fan and compressor are also affected by dirty coils. Cleaning the coils can help extend the lifespan of these components.
  • Improved appearance: A clean air conditioning unit looks better and can add to the curb appeal of your building.

If you are concerned about the condition of your air conditioning unit’s coils, or if you are not comfortable cleaning them yourself, it is a good idea to have a qualified technician inspect them. They can determine if the coils need to be cleaned and can also recommend other maintenance procedures that may be necessary.
