Air Conditioning Coils

Air conditioning coils are an essential component of your AC unit, responsible for transferring heat from inside your home or office to the outside. Over time, these coils can become clogged with dirt, dust, and other debris, causing a range of problems such as reduced airflow, higher energy bills, and even breakdowns. In this article, we’ll explain why it’s important to clean and maintain your air conditioning coils regularly and provide a step-by-step guide on how to do it.

Why Clean and Maintain Air Conditioning Coils?

Dirty air conditioning coils can have a significant impact on the performance of your AC unit. When the coils are covered in dirt, dust or other debris they can’t transfer heat effectively which means less cool air is being produced. This results in decreased efficiency of your air conditioner which translates into increased energy consumption which means higher electricity bills for you. Dirty coils also reduce the lifespan of your air conditioning system by putting extra pressure on its components.

Moreover, dirty coils can negatively affect indoor air quality by allowing mold and bacteria to grow inside the unit. This can cause respiratory problems for those living or working inside the building.

Signs That Your Air Conditioning Coils Need Cleaning

There are several signs that indicate dirty coils need cleaning. These include:

  • Reduced airflow: If you notice that there is less cool air coming from your AC vents than usual.
  • Strange smells: A musty smell coming from your AC unit could be caused by mold growing on dirty coils.
  • Higher energy bills: If you see a sudden spike in your electricity bill without any apparent reason then it’s possible that dirty coils are causing increased energy consumption.

Tools Needed for Cleaning Air Conditioning Coils

Before starting the cleaning process ensure that you have all necessary tools required for cleaning:

  • Screwdriver: To remove screws holding the outer casing.
  • Coil cleaner solution: It helps to break down dirt and grime build-up on the coil surface.
  • Fin comb: Used to straighten bent fins.
  • Gloves: To protect hands from chemicals used during cleaning.

Steps for Cleaning Air Conditioning Coils

  1. Turn off the power supply at the circuit breaker box before opening up any access panels.
  2. Remove any debris around the outdoor unit, such as leaves or branches.
  3. Remove the outer casing carefully using screwdrivers so that you don’t damage the wiring or other components inside.
  4. Spray coil cleaner solution onto both sides of each coil carefully following the manufacturer’s instructions. Allow it to sit for 10 minutes so that it penetrates deep into dirt buildup before rinsing it off with water.
  5. Use a fin comb to straighten any bent fins gently without damaging them, as they are fragile.
  6. Reassemble all parts carefully when done cleaning, including the outer casing but make sure everything is properly sealed before turning on the power supply again at the circuit breaker box.
  7. Test if everything is working fine by checking airflow and temperature settings.

How Often Should You Clean Your Air Conditioning Coils?

The frequency with which you should clean your air conditioning coils depends on various factors like usage patterns or environmental conditions like dust levels etc., but generally speaking, experts recommend doing this once every year at least.

Benefits of Regularly Cleaning and Maintaining Your AC Coils

Regular maintenance will not only increase efficiency but also extend life span while reducing operating costs over time due to lower energy bills caused by better performance levels achieved after the cleaning process has been completed successfully.

Moreover, regular maintenance will help improve indoor air quality, making it healthier for people who live or work inside buildings where these units are installed since mold growth is prevented via regular maintenance.


In conclusion, maintaining and cleaning your air conditioning coils is vital if you want to keep them functioning optimally over their expected lifespan while also avoiding costly repairs down the line resulting from neglecting this important task altogether.

By following our step-by-step guide provided above, along with regular check-ups performed annually by professionals – homeowners can ensure their HVAC systems run smoothly throughout each season without any hiccups!
