Nowadays, the majority of U.S. households rely on air conditioning to beat the summer heat. Given the overwhelming prevalence of central air, most people think they know how to maintain their system properly. But, surprisingly, many homeowners fall victim to common mistakes that waste energy, hike utility costs, and shorten the lifespan of their system.
Avoiding common mistakes can help homeowners like you save money and maintain a comfortable indoor environment. Here are 10 central air conditioning mistakes that can spike your cooling costs:
1. Neglecting Regular Maintenance
Failing to schedule regular maintenance can lead to reduced efficiency and higher energy bills. Ensure your system is inspected and serviced annually to keep it running smoothly.
2. Ignoring Filter Replacement
A dirty or clogged filter restricts airflow, causing the system to work harder and consume more energy. Replace the filter every 1-3 months, especially during peak cooling season.
3. Setting the Thermostat Too Low
Setting the thermostat too low can cause your AC to run continuously, leading to excessive energy use. Aim for a comfortable setting between 75° and 78°F when you’re home and higher when you’re away.
4. Using an Incorrect Thermostat Setting
Using the “on” setting instead of “auto” keeps the fan running constantly, which can increase energy consumption. Set the thermostat to “auto” so the fan only runs when the system is cooling.
5. Not Using a Programmable Thermostat
A programmable thermostat can adjust temperatures based on your schedule, reducing energy use when you’re not home. Set it to raise the temperature when you’re away and lower it before you return.
6. Blocking Vents and Registers
Furniture, curtains, and other obstructions can block airflow from vents and registers, forcing your system to work harder. Ensure all vents are clear to allow proper air circulation.
7. Ignoring Leaky Ductwork
Leaky ducts can lose up to 30% of cooled air, making your system less efficient and increasing costs. Have a professional inspect and seal your ductwork to prevent air loss.
8. Failing to Use Ceiling Fans
Ceiling fans can help distribute cool air more evenly, allowing you to raise the thermostat by a few degrees without sacrificing comfort.
9. Not Sealing Windows and Doors
Poorly sealed windows and doors let warm air in and cool air out, making your AC work harder. Ensure all windows and doors are properly sealed and insulated to maintain a cool indoor environment.
10. Neglecting Insulation
Insufficient insulation in your home can lead to significant energy loss. Proper insulation in attics, walls, and floors helps maintain a consistent indoor temperature and reduces the workload on your AC system.
By avoiding these common mistakes, you can improve the efficiency of your system, lower your energy bills, and maintain a comfortable home environment.
