August is often the month when air conditioners work their hardest. After weeks of high temperatures and humidity, even a well-maintained system can start to show signs of wear. The good news? A few simple habits can help keep your home comfortable while reducing the chances of an unexpected breakdown.
1. Don’t Forget the Air Filter
A dirty air filter is one of the most common causes of poor airflow and unnecessary strain on an air conditioner. During heavy cooling season, check your filter every month. If it looks dirty, replace it—even if it’s earlier than expected. A clean filter helps your system breathe easier and can improve efficiency.
2. Give Your Outdoor Unit Some Breathing Room
Your outdoor condenser needs plenty of airflow to do its job. Remove weeds, trim shrubs, and keep grass clippings, leaves, and mulch at least two feet away from the unit. A little yard maintenance can make a noticeable difference in performance.
3. Keep Vents Open
Closing vents in unused rooms may seem like a way to save energy, but most residential HVAC systems are designed to operate with all vents open. Closing too many can actually increase pressure in your ductwork and make your system work harder.
4. Set It and Forget It
Constantly adjusting the thermostat forces your system to catch up over and over again. Instead, choose a comfortable temperature and let your air conditioner maintain it. If you’re away during the day, a programmable or smart thermostat can automatically adjust temperatures to save energy without sacrificing comfort.
5. Watch for Early Warning Signs
Your air conditioner rarely quits without giving some clues first. Call a professional if you
notice:
- Warm air coming from the vents
- Weak airflow
- Unusual noises or vibrations
- Water leaking around the indoor unit
- Rising electric bills without increased usage
Addressing small issues early is often much less expensive than waiting for a complete system failure.
6. Don’t Ignore Humidity
A properly functioning air conditioner should remove moisture as it cools your home. If your house feels damp or sticky even when it's cool, your system may need attention. Excess indoor humidity can affect comfort and encourage mold growth.
Looking Ahead
While August still feels like summer, cooler weather isn’t far away. Before long, homeowners will be switching from air conditioning to heating. Taking care of your cooling system now—and scheduling regular maintenance for both heating and cooling equipment each year—can help extend the life of your HVAC system and keep it operating efficiently through every season.
A little preventative care today can help you enjoy the rest of summer comfortably while preparing your home for the changing seasons ahead.
