While professional maintenance is essential, there is something you can do for your home’s air conditioning this summer to help keep it running smoothly. That simple task is checking and changing your air conditioning system’s filter as needed.

Did you know that air filters trap dust, pollen, and other airborne particles? Over time, these filters get clogged. When that happens, your system must work harder to push air through, leading to higher energy consumption and costly repairs. In fact, dirty filters are one of the top reasons for HVAC system failures. That’s why knowing how to change your air filter isn’t just handy—it’s essential.

Steps for changing your air conditioning system filter

1. Identifying the filter location

The first step in changing your air filter is knowing where to find it. Most central air conditioning systems have filters located either in the return air duct or the blower compartment. If you’re unsure, consult your HVAC system’s manual.

Return air duct: Look for a large metal grille. This is usually where the air filter is located.

Blower compartment: For some systems, you’ll find the filter in the blower compartment, generally next to the furnace or air handler.

2. Purchasing the right filter size

Once you’ve located the filter, you need to know its size. Filters come in various sizes, and using the wrong one can reduce efficiency. Check the old filter for size markings, or measure the dimensions yourself. Common sizes include 16×25 inches or 20×30 inches.

Filter types: Choose between fiberglass, pleated, or high-efficiency particulate air (HEPA) filters. Each has its pros and cons regarding cost and air filtration efficiency.

MERV rating: The Minimum Efficiency Reporting Value (MERV) rating indicates how effectively a filter traps particles. For most homes, a MERV rating between 8 and 12 is sufficient.

3. Removing the old filter

Before you replace the filter, turn off your HVAC system. This ensures your safety and prevents dust from circulating while the filter is out.

4. Installing the New Filter

Now that the old filter is out, it’s time to install the new one. Follow these steps for a smooth installation.

Benefits of A/C filter changes

Changing your air filter regularly does wonders for the air quality in your home. Dirty filters can’t trap pollutants effectively, allowing dust, mold spores, and allergens to circulate freely. This can aggravate allergies and respiratory conditions.

A clean filter ensures that the air circulating in your home is free of harmful particles. This is especially important if you have pets, as pet dander can quickly clog an air filter.

When your HVAC system doesn’t have to work hard to push air through a clogged filter, it runs more efficiently. This means your system will last longer and require fewer repairs, saving you money in the long run.

A clean air filter can lower your energy consumption by up to 15 percent. This is because your HVAC system can maintain the set temperature more easily when airflow is unobstructed. Over time, this translates to significant savings on your energy bills.
