9 Reasons Why Your Air Conditioner Filter Must Be Replaced Often

An air conditioner filter is a key component to maintaining healthy air quality in your home. It works by trapping dust, pollen, and other airborne particles so they don’t end up in the air you breathe. Without an air conditioning Sydney filter, your indoor air could become very polluted, potentially leading to health issues like asthma or allergies.

Air conditioning filters come in many different shapes and sizes to fit any kind of unit. The most common type is the throwaway fibreglass panel filter which needs to be replaced regularly (usually every month).

It's important to stay on top of your air conditioner filter maintenance. Not doing so can result in numerous problems down the road, such as decreased efficiency, shorter system lifespan, and higher energy costs.

The following list details the reasons why you should regularly change your air conditioner filter.

Improved Air Quality

A clogged air filter restricts the flow of air through the system, resulting in dirt and dust particles being circulated throughout your home. Replacing your filter regularly helps keep those airborne pollutants and allergens out of your living space.

Better Performance

Dirty filters reduce airflow which can cause wear and tear on some parts of the cooling unit like the motor and fan blades. This reduces its performance capabilities over time.

Reduced Wear and Tear

A dirty filter is much harder on the system, as mentioned above. Replacing it often helps to keep the air conditioner running smoothly for many years to come.

Longer System Lifespan

If you don’t replace your filter regularly, you can expect a shorter lifespan from your cooling unit due to increased wear and tear caused by dirt accumulation. Regular maintenance of the filter can add years to its overall life expectancy. 

Lower Energy Costs

When the air conditioner has to work harder because of clogged filters, more energy is used to do so which results in higher electricity bills each month. 

Cleaner Coils

The air conditioner's evaporator and condenser coils also have to be kept clean for the system to work efficiently. When these are blocked by dirt and dust, the heat exchange process is hindered causing higher energy consumption.

Maintained Airflow

In addition to keeping your coils clean, a regularly replaced filter ensures that air is moving through the system at proper levels which helps maintain consistent temperatures throughout your home. 

Reduced Chance of System Malfunction

Clogged filters lead to wear and tear on other parts of the cooling appliance which can eventually cause it to malfunction or break down entirely if not caught soon enough. Replacing your filter often reduces this risk significantly. 

Healthy Environment

Dirty filters can propagate the growth of mould, mildew and other harmful pollutants that can be hazardous to your health. Replacing them regularly helps keep your home environment safe and healthy for you and your loved ones. 

When replacing your air conditioner filter, be sure to check its MERV rating. This stands for Minimum Efficiency Rating Value and is a measure of how efficient a filter is at reducing airborne pollutants. The higher the MERV value, the better job it will do at trapping dust, mould spores, and other small particles that can cause health issues. 

The best way to keep your indoor air clean and healthy is to replace your air conditioner filter regularly and use a high-efficiency filter when possible. Doing so will help ensure that you and your family are breathing in clean, healthy air at all times. 

Checking and replacing your air conditioner filter may seem like a chore, but it’s an important part of maintaining the health of your home and everyone living inside it.  By following these simple steps, you can keep the air in your house free from allergens and pollutants for years to come!

Maintaining regular filter replacements should always be a top priority for any homeowner with an air conditioner. Not only will it help extend the lifespan of your system, but it also increases its efficiency while helping reduce energy costs as well as potential health risks. If you're ever unsure about how often to change your filter, consult a professional technician who can assess the condition of your AC unit and advise you on what maintenance practices are best suited for it.
