How to Change HVAC Filter at Home – A Simple Step-by-Step Guide

For an HVAC system to operate efficiently and last longer, regular maintenance is necessary. Changing the air filter is one of the most important yet often overlooked tasks. Not only does this simple task help maintain the air quality in your home, but it also keeps your HVAC system running smoothly. If you’re wondering how to change the HVAC filter at home, we’ve got you covered! In this guide, we’ll walk you through the easy steps for replacing your air conditioner filter and provide tips for proper HVAC filter maintenance.

Why Is Air Conditioner Filter Replacement Important?

Let’s take a quick look at why changing the air filter is so important before moving on to the stages. Your HVAC system has an air filter that traps dust, dirt, pollen, and other debris to keep them from circulating through your home’s air. Over time, this filter becomes clogged with particles, reducing airflow and causing the system to work harder than necessary. A dirty filter can also result in poor indoor air quality, leading to allergies or respiratory issues.

Changing your HVAC filter regularly improves the efficiency of your air conditioning unit, keeps the air clean, and helps prevent costly repairs down the road. Replacing it every 1 to 3 months is generally recommended depending on the filter type and usage.

How to Replace Air Conditioner Filter at Home – Step-by-Step Guide

Turn Off the HVAC System

Before working on your HVAC system, turn off the power to prevent accidents. You can do this by turning off the thermostat and switching off the HVAC unit at the circuit breaker.

Locate the Air Filter

Next, locate the air filter. In most homes, the filter is found in one of three places:

• Return Air Ducts: Usually located in hallways or walls.
• Air Handler Compartment: Located near the furnace or HVAC unit itself.
• Ceiling Vents: In some modern homes, filters can be found in ceiling vents.

If you’re unsure where your filter is located, check the owner’s manual for your specific HVAC system.

Check the Filter Size

Before removing the filter, check the size of the current filter. The size is typically printed on the side of the filter itself, including measurements such as 16x20x1 or 20x25x1. Note the dimensions so you can purchase the correct replacement filter. If you’re unsure of the size, you can bring the old filter to a hardware store for assistance.

Remove the Old Air Filter

Once you have the correct filter size, carefully remove the old filter. Most filters slide right out, but some may require you to release them from a holder or latch gently. Be cautious when handling the dirty filter, as it can be covered with dust and debris. Dispose of the used filter properly.

Install the New Air Filter

Now, it’s time to install the new filter. Ensure that the filter’s arrows (usually printed on the side) point in the airflow direction. The airflow direction is important because it ensures the filter is working correctly. Most filters will have a noticeable arrow; if not, check the unit’s owner manual for guidance.

Slide the new filter into place, ensuring it fits snugly and doesn’t leave any gaps around the edges.

Check for Airflow and Functionality

Once the new filter is installed, checking for proper airflow’s a good idea. Turn the HVAC system back on and ensure the air flows freely through the vents. If you notice any issues or unusual sounds, turn off the system and check to ensure the filter is seated correctly.

If everything looks good, you can turn the system back on and allow it to function normally.

Set a Reminder for Next HVAC Filter Replacement

Keep in mind that, depending on the type of filter and how frequently your system operates, HVAC filters should be changed every one to three months. Consider setting a reminder on your phone or using a calendar to keep track of when it’s time to replace the filter again. You can also sign up for air conditioner maintenance services, often including filter replacement as part of routine upkeep.

How Often Should You Change the Air Conditioner Filter?

The type of filter you use, how frequently your HVAC system operates, and the quality of the air in your house are some of the variables that affect how frequently you should replace your air filter.

Here are some general guidelines:

• Standard fiberglass filters: Replace every 30 days.
• Pleated filters: Replace every 60-90 days.
• HEPA filters: Replace them every 6 months (or as the manufacturer directs).
• Homes with pets or smokers: Replace filters every 30-60 days.

If you have allergies or asthma, you may want to change the filter more often to maintain better air quality in your home.

Air Conditioner Filter Maintenance Tips

• Inspect the filter regularly: Even if you don’t need to replace it, it’s a good idea to check it every month to ensure it’s not clogged.
• Clean the surrounding area: Dust and debris can accumulate around the filter, so it’s essential to clean the area around the filter compartment to prevent buildup from affecting airflow.
• Use the right filter: Not all filters are created equal. Select a filter based on your system’s MERV (Minimum Efficiency Reporting Value) rating. Higher MERV ratings trap smaller particles but can reduce airflow if your system isn’t designed for them.
• Consider a professional HVAC inspection: While changing the filter is something you can do yourself, it’s still a good idea to schedule professional HVAC service in Tampa, or wherever you live, regularly. A qualified technician can inspect your system, perform maintenance, and address any performance issues.
