AC Filter for Any Air Conditioning System

Yes, in most central HVAC systems, the same filter is used for both your air conditioner and your furnace. It's located in the shared air handler. The key is to use the correct size and MERV rating for your system.

A simple visual check is best. Hold the filter up to a light. If you can't see light passing through it, it's time for a new one. For most homes, this is every 1-3 months, especially during heavy use in the summer.

Absolutely. A clogged filter can severely restrict airflow, causing your system's evaporator coils to freeze over. This can lead to poor cooling performance and even permanent damage to your compressor. It's the most common and preventable cause of AC failure.

For most residential air conditioners, MERV 8 is the perfect balance. It provides great filtration without overworking the system. If you have significant allergies, a MERV 11 filter is a good option, but check your system's manual before going higher.

While the brand of your HVAC unit is important, the filter brand is less so. What truly matters is that the filter is the correct size, has the right MERV rating, and is made from quality materials. As an authorized dealer for top brands, we guarantee all three.
