Things You Should Know About Air Filters

Air Conditioning and Heating

HVAC filters fill two invaluable roles: preventing dust and other particulates from accumulating in your air handler and cleaning the air as it recirculates through your home. A clogged filter will reduce the volume of air that can pass through the system, which means that your system will have to run longer to provide the same amount of heating or cooling in your Grapevine, TX home. Replacing your air filter on a regular basis is one of the easier and more affordable ways you can maintain your HVAC system and minimize your utility bills.

Different Filter Types

By and large, filters are disposable. Once they grow dirty, simply remove them, throw them out, and replace them with identical filters. Some filters are washable and can be hosed off dozens of times with no performance loss, but these products tend to trap fewer of the smaller particles that can cause respiratory issues. If in doubt, purchase the same filter type and size from the same manufacturer to ensure compatibility.

Better Filters Aren’t Always Better

One of the most common questions we get is about upgrading an air filter to a higher-end product that can trap smaller particles or one that excels at minimizing odors. Surprisingly, the answer is a bit more complicated than you’d expect.

Your HVAC system runs best at a certain air pressure, and upgrading your air filter can reduce your air pressure much as a dirty filter will. Combined with the fact that most indoor air quality issues can be resolved with a portable air purifier or vacuum, it’s often better to save some money with a cheaper baseline filter than a top-of-the-line one.

Replacement Schedule

We recommend replacing air filters at least twice a year, but waiting longer than a year can cause serious performance issues. Clean washable filters monthly, and if they start to tear, replace them. If you’re generating a lot of dust with a remodel or opening up the windows often, check your filters biweekly.
