5 Ways to Improve Your Home’s Airflow with Outdated AC

HVAC System on the outside of a house.

Your older air conditioner may still be soldiering on, but you can tell that it’s lost efficiency. Weak airflow, hot spots, and stale air can all be signs that your system is past its prime. But if a full AC replacement isn’t in the cards just yet, there are still ways to improve ventilation and help your system out. Let’s look at a few simple steps Kansas City homeowners can take to get better airflow, even with an aging AC unit.

Inspect & Seal Ductwork

Leaky ducts are one of the biggest hidden causes of poor airflow. In fact, the U.S. Department of Energy estimates that up to 30% of air can be lost through holes, gaps, or poorly connected ducts. That’s a big chunk of cooled air going to waste—especially in an older system. You can check exposed ductwork in attics, basements, or utility closets for visible cracks or loose connections. Sealing small leaks with mastic sealant or metal tape can help, but for larger issues, it’s best to call in a professional for duct repair.

Use Ceiling or Area Fans

If your AC isn’t circulating air like it used to, fans can pick up the slack. Ceiling fans help push cool air down and keep it moving throughout the room. Just remember to set them to rotate counterclockwise in the summer. If you don’t have ceiling fans, portable area fans are an easy and affordable way to create a breeze and improve comfort. They don’t cool the air themselves, but they make the space feel cooler by improving airflow.

Open Windows Strategically

Kansas City nights can sometimes bring a break from the heat, so use that to your advantage. Opening windows on opposite sides of your home can create cross ventilation and naturally move air through the space. This technique works best in the early morning or late evening when outdoor temperatures are low. Just make sure to close them again before it heats up to avoid bringing in warm, humid air during the day.

Get Professional AC Maintenance Done

Even if your old AC is well past its prime, regular AC maintenance can go a long way in improving how well it works. A tune-up helps ensure all parts are functioning efficiently and can uncover small issues before they become bigger problems. One of the simplest improvements you can make is changing your air filter more often—every 1 to 2 months during heavy use. A clean filter allows air to move freely, helping your system distribute cooled air better throughout the home.

Invest in an Air Purifier

Older air conditioners often struggle with airflow because of a heavy filtration load. That’s where a whole-home air purifier can help! These systems capture airborne particles before they reach your HVAC filter, reducing strain on the AC and improving indoor air quality at the same time. With less dust, pollen, and debris clogging up the filter, your system won’t have to work as hard to push air through—resulting in smoother, more consistent airflow.
