The Right Filter Matters

The air filter in your AC and furnace is the key to your home’s health and your system’s lifespan. Let’s find the perfect one for your Seguin home.

Understanding MERV Ratings

MERV (Minimum Efficiency Reporting Value) tells you how well a filter stops dust and allergens. A higher number means cleaner air, but it also makes your system work harder. Choosing the right balance is key.

 

MERV 1-4

Basic Protection

These standard fiberglass filters stop large particles like lint and dust. They are designed to protect your HVAC system, not improve your air quality.

MERV 8-10

Good (Most Homes)

This is the sweet spot. These pleated filters capture pollen, mold spores, and pet dander, offering a great balance of filtration and airflow for most homes.

MERV 11-16

Best (Allergies)

For homes with severe allergies or respiratory issues. These capture bacteria and fine dust. Warning: Many residential systems cannot handle this much restriction. Ask us first!

When Should You Change It?

A clogged filter chokes your HVAC system, increasing bills and leading to breakdowns. How often you change it depends on your filter and your home.

Every 30 days.

1-inch Pleated Filters (MERV 8)

Every 60-90 days.

4-inch Media Filters (MERV 11+)

Every 6-12 months.

Frequently Asked Questions About Filter Replacements in Seguin, TX

How often should you change your AC air filter?

This depends on your filter type and home environment. Standard 1-inch filters (like the basic fiberglass or pleated ones) should be changed every 30-90 days. If you have pets or severe allergies in your Seguin or San Antonio home, you should check it monthly. Thicker 4-inch media filters (MERV 11+) can last much longer, typically 6 to 12 months.

No, you should never run your AC without a filter. The filter’s most important job is to protect your expensive equipment. Without it, dust, debris, and pet hair are sucked directly into the sensitive evaporator coil. This will quickly cause the coil to clog, freeze up, and can lead to costly breakdowns, reduced efficiency, and poor performance.
