The Importance of AC Filters

AC filters trap dust, dirt, and other particles from the air. When these filters get dirty, they can’t work as well. This makes your AC work harder to cool your home. A clean filter helps keep the air fresh and reduces the strain on your system. When you change your filter regularly, you save money on energy bills and repair costs.

How Often Should You Change Your Filter?

Most experts say to change your AC filter every 1 to 3 months. However, a few factors can change this:

1. Type of Filter

Different filters have different lifespans. Some last longer than others. Here are a few common types: – Fiberglass Filters: Change them every month. – Pleated Filters: These can last 3 months. – HEPA Filters: Best for allergies and last about 6 months.

2. Pets in the Home

If you have pets, you should change your filter more often. Pet hair and dander can clog the filter quickly. If you have 1 or 2 pets, check your filter every month.

3. Allergies

If someone in your home has allergies, you might want to change your filter more often. A clean filter helps trap allergens and keeps the air clearer.

4. Local Climate

Here in Fort Worth, the weather can be very hot in summer and chilly in winter. During hot months, you might run your AC more. This means changing the filter more often. In winter, check the filter every 2 to 3 months.

Filter Type	Lifespan	Ideal for
Fiberglass	1 month	Budget-friendly options
Pleated	3 months	General household use
HEPA	6 months	Allergy sufferers
Washable	1 month (clean)	Eco-friendly and reusable

How to Change Your AC Filter

Changing your AC filter is easy. Here are the steps to follow:

Step 1: Turn Off Your AC

Before you start, make sure the system is off. This keeps you safe.

Step 2: Find the Filter

Look for the filter. It’s usually near the AC unit or in the air handler.

Step 3: Remove the Old Filter

Carefully pull out the old filter. Check for any dirt or damage.

Step 4: Insert the New Filter

Take your new filter and slide it into place. Making sure the arrows on the filter point toward the AC unit.

Step 5: Turn Your AC Back On

Once the new filter is in, turn your AC back on. You should feel the difference in air quality right away!

Signs You Need to Change Your Filter

Sometimes, you might forget to check your filter. Here are some signs that tell you it’s time for a change:

1. Reduced Airflow

If you notice less air coming from your vents, it might be a dirty filter. Check it right away.

2. Dust and Allergies

If you start sneezing more or see dust build-up in your home, it’s time to change the filter.

3. Higher Energy Bills

When your AC works harder, it uses more energy. If your bills go up suddenly, check your filter.

The Benefits of Regularly Changing Your Filter

Changing your AC filter regularly has many good points:

1. Better Air Quality

A clean filter helps keep the air fresh. This is great for your health, especially in the hot Texas summers.

2. Longer AC Life

Your AC will last longer if it doesn’t have to work as hard. This means fewer repairs and replacements.

3. Energy Savings

You can save money on your energy bills when your AC runs efficiently. A clean filter helps it do just that.

Additional Benefits of a Clean Filter

Decreased risk of system failure
Improved comfort levels in your home
Reduced environmental impact by lowering energy consumption

Choosing the Right Filter for Your Home

When you buy a new filter, make sure you get the right one. Consider these factors:

1. Size

Check the size of your current filter. This is usually printed on the side.

2. MERV Rating

The Minimum Efficiency Reporting Value (MERV) tells you how well a filter traps particles. A higher number means better filtration. For most homes, a MERV rating of 8 to 12 works well.

3. Type

Choose the type of filter that fits your needs. If you have pets or allergies, consider HEPA filters. For general use, a pleated filter is a good choice.

Local Considerations for Fort Worth

In Fort Worth, the weather can be tough. The hot summer months mean your AC works a lot. Dust storms can also bring in dirt and particles. Because of this, you might want to change your filter every month during peak summer.

Seasonal Consideration	Suggested Filter Change Frequency
Spring	Every 2 months
Summer	Every month
Fall	Every 2-3 months
Winter	Every 2-3 months

The Cost of AC Filters

AC filters are not too expensive. Depending on the type and brand, you can spend anywhere from 5 dollars to 30 dollars for a single filter. Buying in bulk can save you money if you plan to change them often.

How to Remember to Change Your Filter

Keeping track of when to change your AC filter can be tricky. Here are some tips to help you remember:

1. Set a Calendar Reminder

Use your phone or a calendar to set up monthly reminders.

2. Check It with Other Tasks

You can check the filter during other home maintenance tasks, like changing smoke detector batteries.

3. Keep Spare Filters Handy

Buy extra filters and keep them in an easy-to-reach place. This way, you can change it right away when you check.

Cleaning vs. Replacing Filters

Some filters are washable. You can clean these instead of replacing them. If you have a washable filter, make sure to clean it every month. Let it dry completely before putting it back.

However, most disposable filters should be replaced. Check the manufacturer’s guidelines for recommendations.

What Happens If You Don’t Change Your Filter?

Not changing your filter can lead to several problems:

1. Buildup of Dirt

Over time, dirt and dust can clog your system. This makes your AC work harder and less efficiently.

2. Higher Repair Costs

When the system works harder, it can break down more often. This leads to costly repairs.

3. Health Issues

Dirty filters can cause health problems. Dust and allergens can circulate in your home. This can make allergies and asthma worse.

Conclusion

Changing your AC filter is a simple but important task. Keep it clean, and you can enjoy better air quality and a more efficient system. Remember, check that filter every 1 to 3 months. Choose the right type for your home. With regular care, your AC will be ready to keep you cool all summer long.
