Keeping your air conditioning system running smoothly requires routine maintenance. One of the most important steps in this process is changing the air filter regularly. The filter in your air conditioning system traps dirt and other contaminants in the air stream before they reach the rest of your home. If the filter gets too dirty, it can reduce your system’s efficiency and increase the amount of energy it takes to cool your home. Additionally, dirty filters can cause other problems such as reducing air flow and increasing the amount of dust and debris in your home.

How often should you change your filter?

The EPA recommends changing your HVAC air filter every three months. This can reduce the amount of dust and other contaminants in the air, improving the quality of your indoor air and lowering your energy bills. Dirty or clogged air filters can also decrease the life of your HVAC system. If you live in a dusty area, you may need to change your filter more frequently. If you have pets or live in a humid climate, you may need to change your filter more often. If you have allergies or asthma, you may want to change your filter more frequently.

How to change your air conditioning filter

The first step in changing your filter is locating the filter. HVAC systems use large metal or plastic filter baskets that are usually located in the central part of the house. The filter baskets are often attached to a duct, so you may need to remove the duct cover to access them. The filter baskets may also be built into a wall-mounted air handler or air conditioning unit. You can purchase replacement filters at most hardware and home improvement stores. Some filters are disposable, while others can last for several months. Check the manufacturer’s recommendations to determine how often to change your filter. When changing your filter, be sure to dispose of the old filter properly to avoid clogging your HVAC system.

When to replace the air conditioner filter

If you have pets, you should change your filter more frequently. Pets shed fur and other particles that can clog up your filter and cause other issues with your HVAC system. If you live in a humid climate, you should change your filter more frequently. Humidity can cause your HVAC system to work harder to cool your home. This can decrease your system’s efficiency. If you have allergies or asthma, you should change your filter more frequently. Dirty filters can increase the amount of dust and other contaminants in the air, increasing your risk of allergies or asthma attacks.

How to clean your air conditioning filter

You can clean your filter by using a hose and washing it off outside your home. Be sure to use a hose that does not have chemicals in it. This will help you avoid damaging your HVAC system. You can also clean your filter by rinsing it with a hose and detergent inside your home. You can use a small amount of dish soap or a mild cleaning solution. You can also use a vacuum cleaner to clean your filter. You may want to wear gloves, as you may come into contact with chemicals in your filter.


Air filters are an essential part of any HVAC system. They trap dirt and other contaminants in the air before they reach your home. Without filters, your HVAC system would be working much harder to push air through the system. This can lead to higher energy bills and an increase in wear and tear on your HVAC system. To keep your air filters clean and working properly, be sure to change them regularly. You can also clean them to extend their life and prevent them from becoming dirty too quickly.
