Change Your Ac Unit’s Air Filter And Save Money On Energy Bills: Here’s How!

Maintaining a clean air filter in your AC unit is crucial for ensuring optimal performance, indoor air quality, and energy efficiency. A clogged filter can restrict airflow, leading to a decrease in cooling capacity, increased energy consumption, and potential damage to the unit. In this comprehensive guide, we will delve into the step-by-step process of how to change air filter ac unit, empowering you to keep your AC running smoothly and your indoor air fresh.

Locating Your Air Filter

The first step is to locate your air filter. It is typically housed in a metal or plastic frame located inside the air handler unit, which is usually situated in a closet, attic, or basement. If you have a central air conditioning system, the air handler unit will be connected to the ductwork throughout your home.

Types of Air Filters

There are various types of air filters available, each with different efficiency ratings. The most common types include:

• Fiberglass filters: These are the most basic and least expensive option, but they offer minimal filtration.
• Pleated filters: These are more efficient than fiberglass filters and have a pleated design that increases the surface area for trapping particles.
• HEPA filters: These are the most efficient type of filter, removing up to 99.97% of airborne particles, including allergens, dust, and smoke.

How Often to Change Your Air Filter

The frequency at which you should change your air filter depends on several factors, including the type of filter used, the number of occupants in your home, and the level of dust and pollution in your area. As a general rule of thumb, it is recommended to change your filter every 30 to 90 days.

Tools and Materials

To change your air filter, you will need the following tools and materials:

• New air filter
• Screwdriver or hex key (if necessary)
• Vacuum cleaner
• Gloves (optional)

Step-by-Step Guide

1. Turn Off the AC Unit

Before starting, turn off the power to your AC unit at the circuit breaker or fuse box. This will prevent any accidental electrical shocks.

2. Locate and Remove the Filter Access Panel

Locate the filter access panel on the air handler unit. It is usually held in place by screws or a latch. Remove the panel to expose the air filter.

3. Remove the Old Filter

Carefully slide the old air filter out of the frame. Avoid touching the filter surface as it may contain dust and allergens.

4. Clean the Filter Area

Use a vacuum cleaner to remove any dust or debris from the filter area. This will help prevent the new filter from becoming clogged prematurely.

5. Insert the New Filter

Insert the new air filter into the frame, making sure that the airflow arrows on the filter are facing the correct direction.

6. Secure the Filter Access Panel

Replace the filter access panel and secure it with screws or the latch.

7. Turn On the AC Unit

Turn the power back on to the AC unit and allow it to run for a few minutes to circulate the air and distribute the clean air throughout your home.

Additional Tips

• Use a higher-efficiency filter: Consider using a pleated or HEPA filter for better air filtration.
• Check your filter regularly: Even if you change your filter every month, it is a good idea to check it periodically for any clogs or damage.
• Clean your AC unit: A clean AC unit will help your air filter last longer and perform more efficiently.
• Call a professional if needed: If you encounter any difficulties or if your AC unit is not performing properly after changing the filter, do not hesitate to call a qualified HVAC technician.
