Signs Your Air Conditioning Unit Needs To Be Cleaned

Efficient Hygiene Services • February 23, 2023

One of the key aspects of maintaining your air conditioning unit is regular cleaning. A dirty air conditioning unit not only leads to a decrease in efficiency, but it can also cause health problems.


In this blog post, we’ll go over the signs that your air conditioning needs to be cleaned and provide tips for effectively maintaining your unit.


Why Air Conditioner Cleaning Is Important


Cleaning your air conditioning unit is important for several reasons. First and foremost, a dirty unit will lead to a decrease in efficiency. When the air filter is clogged with dirt and debris, it restricts airflow and forces the unit to work harder to cool the air. This results in increased energy consumption and higher utility bills.


A dirty air filter can also cause the unit to freeze up, which can lead to costly repairs. Another reason why cleaning your air conditioning unit is important is for your health. A dirty air filter leads to poor indoor air quality, which can trigger respiratory problems, allergies and other health issues. Regular cleaning of your air conditioning unit can help improve indoor air quality and promote a healthy living environment.


Signs Your Air Conditioner Needs To Be Cleaned



Common signs that your air conditioning unit needs to be cleaned include:

  • Reduced or weak airflow

    If you notice that the air coming from your vents is weaker than usual, it could be due to a clogged air filter or other debris inside the unit.

  • Air coming from vents isn’t cold

    Dirty evaporator coils or a clogged air filter can reduce the unit’s cooling capacity, resulting in warmer air coming from the vents.

  • Musty or unpleasant smells

    This could be a sign of mould or bacteria growth inside the unit, which can be harmful to your health and should be addressed immediately.

  • Increased energy consumption and bills

    When the unit is clogged with dirt and debris, it has to work harder to cool your home, resulting in higher energy consumption and bills.

  • Unit freezing up

    If you notice ice forming on your unit, it could be due to a dirty air filter or evaporator coils. When the unit is clogged, the airflow is restricted, causing the coils to freeze up.

  • Poor indoor air quality

    When the unit is clogged with dirt and debris, it can circulate allergens, dust, and other pollutants throughout your home.

  • Dust and debris accumulating on the outside of the unit

    This could be a sign that it needs to be cleaned. This can also reduce the unit’s efficiency and cooling capacity.

  • Mould inside the unit

    This can be harmful to your health and should be addressed immediately.

  • If you own pets or live in a dusty area

    Pet hair and dust will accumulate inside the unit, reducing its efficiency and cooling capacity. You may need to inspect and clean your unit more often if this is the case.


When To Clean Your Air Conditioning Unit


The frequency of cleaning your air conditioner will depend on several factors, including the location of your unit, how often it’s used and whether or not you have pets. Generally, we recommend cleaning your unit once a year, however you should increase frequency if you notice any of the above signs.


Tips For Quick Cleaning Your Air Conditioner


Performing a quick cleaning of your air conditioning unit is a relatively simple process that can be completed in a few steps.


  1. Turn off the power to the unit,
  2. Remove the air filter and clean it with a soft brush or vacuum. If the filter is damaged or worn, it should be replaced.
  3. Clean the outside of the unit, removing any dirt that has accumulated on the fins.
  4. Finally, turn the power back on and test the unit to ensure it’s working properly.


Please remember that there is always risks when cleaning electrical appliances and to take extra precautions. If you are inexperienced in performing these works, please contact the experts at Efficient Hygiene Services.
