Air Conditioning Mistakes That Cost You Money

Keeping cool and comfortable during these hot summer months while keeping utility costs down can feel like a losing battle. And it can be even more costly if your central air conditioning system isn’t used efficiently. Many homeowners unknowingly make mistakes that increase energy consumption and drive up their utility bills. Yet with a little no-how, you can keep costs down without sacrificing indoor comfort, even on the hottest of day.

Here are some common air conditioning mistakes to avoid to keep your cooling costs in check.

1. Neglecting Regular Maintenance

One of the most common mistakes is neglecting regular maintenance. An AC unit needs periodic servicing to run efficiently. Dirty filters, clogged ducts, and low refrigerant levels can force your system to work harder, using more energy. Schedule annual maintenance with a professional to ensure your system operates at peak efficiency and catches minor issues before they become costly repairs.

2. Incorrect Thermostat Settings

Setting your thermostat too low in an attempt to cool your home quickly can backfire. This practice doesn’t speed up the cooling process; it just keeps your AC running longer, consuming more energy. The U.S. Department of Energy recommends setting your thermostat to 78°F when you’re home and raising it when you’re away. Programmable thermostats can automate these settings, optimizing your cooling schedule and saving energy.

3. Ignoring Air Leaks

Air leaks around windows, doors, and in ductwork can cause cool air to escape, making your AC work harder to maintain the desired temperature. Sealing these leaks with weather stripping or caulking can significantly improve your home’s energy efficiency. Additionally, ensure that your ductwork is properly insulated to prevent energy loss.

4. Blocking Vents and Airflow

Furniture, drapes, or other objects blocking vents and registers can restrict airflow, causing your AC to work harder to cool your home. Ensure that all vents are open and unobstructed to allow for even distribution of cool air.

5. Not Using Ceiling Fans

Ceiling fans can complement your AC by circulating cool air more efficiently. This allows you to set the thermostat a few degrees higher without sacrificing comfort. During summer, set your ceiling fans to rotate counterclockwise to create a cooling breeze.

6. Overlooking the Impact of Heat Sources

Heat-generating appliances like ovens, stoves, and even some electronics can raise your home’s temperature, making your AC work harder. Use these appliances during cooler parts of the day, or opt for alternatives like grilling outside. Additionally, switching to energy-efficient lighting can reduce heat buildup.

7. Not Utilizing Natural Ventilation

On cooler days or during the evening, turn off your AC and open windows to allow natural ventilation. This can give your AC a break and reduce energy consumption. However, make sure to close windows and blinds during the day to keep the heat out.

By avoiding these common mistakes, you can enhance the efficiency of your air conditioning system, maintain a comfortable home environment, and reduce your summer utility costs.
