Why Changing Your Air Filters Is Important

Updated: Mar 2



During the year, your air filter puts a lot of work into keeping your home clean. However, the dust your filter collects doesn’t just go away. Instead, it continues to build up. Over time, if you don’t swap it out, it can start to affect your HVAC system, your wallet, and even your quality of life!


It’s important to keep your AC unit summer-ready, especially when you live somewhere that can get pretty warm, like San Antonio! Maintaining and replacing your air filter every few months is the best way to keep your air fresh.


If it's been a while since you've replaced your air filter, you may need to know what can happen when you leave an old or dirty filter alone. Fortunately, the experts at Yeti Cooling & Heating are here to help with some tips.

Air Quality

The number one reason you'll want to change your air filter is to improve the quality of the air you breathe. Dirt and dust can clog up your AC filter and reduce air quality. Pet dander or smoking can make this even worse.


Your AC filter should be primarily white. If your air filter is gray or even black, changing it will immediately improve your household’s air quality.

Health and Wellness

Did you know, health and wellness are tied to air quality? Unclean air filters can often cause seasonal allergies to worsen, especially with indoor allergens. In more humid climates, moisture can get trapped in your HVAC system and wreak havoc. This makes it easier to develop illnesses.

Energy and Cost Efficiency

If you haven't had an air filter replacement in a while, chances are your HVAC system is working overtime to push air through your ducts. Overworked HVAC systems have to work harder, which means higher utility bills. This is especially true in hotter climates like here in San Antonio.


When you give your AC unit the preventative maintenance it needs, you'll end up saving money and reducing emissions. This is better for your wallet and the planet! At Yeti Cooling & Heating, we can help with seasonal tune-ups to keep your system fresh and clean.

Air Filter and HVAC System Health

Letting your filter accrue buildup can cause an increase in wear and tear on your HVAC system. If you leave dirty filters in place, it can eventually even make your AC break down entirely, leaving you without relief on a hot south Texas day.


Getting your AC filters changed and your HVAC system checked on a regular basis can help to prevent premature breakdowns. At Yeti Cooling & Heating, our maintenance services can resolve small issues before they have a chance to cause major damage. This can keep you from needing to buy an entirely new unit, which is a costly and time-consuming experience.
