HVAC Maintenance: How to Clean Your Air Conditioner Unit

When was the last time you cleaned your air conditioner unit?


The HVAC system in your home is doing more work than you might realize, and you may have more work on your hands to maintain this system than you might realize. Routine maintenance is an investment in the function and cost of heating and cooling your home. If your filters get clogged or your system is overworked, you could end up writing a large paycheck for repairs or replacements. Learn how to maintain your HVAC system to save money and keep your house a comfortable temperature.

Let’s start with the basics of HVAC maintenance: cleaning your air conditioner filter.

Why It’s Important to Keep Your Air Conditioner Unit Clean

Air conditioner units filter through a lot of dirt and debris as they disperse cool air throughout your home. Too much dirt and debris can clog up your filter and prevent air from flowing easily. If dirt and debris are clogging your filters, more dirt and debris will be filtered as it moves through your home. Dispersing dirt and dust can cause a variety of health problems, especially for homeowners or residents that have seasonal allergies or respiratory conditions. If your household is experiencing a high level of sneezing, sore throat, or breathing issues, the solution to your health problems may lie in cleaning your AC filter.


Free airflow also helps to move condensation from cool air throughout the unit. Clogged filters and stifled airflow causes condensation to freeze. Ice will accumulate in the filter and the moisture from this ice could cause damage to the air conditioner or leakage in the area. Clogged filters also increase the risk of fires in your home.


All of the problems caused by clogged filters put more work on your air conditioning system as a whole. The more work your AC has to do to cool your home, the more energy and money you will have to spend for comfortable temperatures.

Tips for Cleaning Your AC Filter

At the very least, you should be cleaning your air conditioner filter to promote proper airflow and prevent damages to your air conditioning unit. Filters should be cleaned once every few weeks; every three months at the latest. If you are using the air conditioner more often, you should clean the filter more often.


To clean the filter, turn off your air conditioner and remove the mesh filters from behind your unit’s front grille. You may notice that it is covered in dust and debris, especially if you have not cleaned the filter in a long time. Gently take the unit outside – hitting or bumping the filter while you are inside will return the dust to the room inside the house. Shake out the filter outside and remove any remaining debris with a vacuum or a hose. If you want to hose down the filter, mix a small amount of baking soda with water and apply it to the filter before you rinse. The baking soda will help to remove any odour that has built up. Leave the filter out to dry for a few hours before putting it back into your system.
