When summer temperatures rise, your central air conditioning system becomes one of the most important appliances in your home. While it’s a complex system, there are several tasks you can do on your own to help keep things running efficiently. Staying on top of these basic maintenance steps can improve your system’s performance, lower your energy bills, and extend the lifespan of your equipment.
Here are 10 easy central air conditioning tasks every homeowner can handle — plus insight into when it’s time to bring in the professionals like the trusted team at Brideau Energy.
Your air filter should be replaced or cleaned every 1–3 months depending on usage and type. A dirty filter restricts airflow and forces your system to work harder, using more energy and reducing comfort.
Make sure your outdoor condenser unit is free of leaves, grass clippings, and other debris. Trim any nearby bushes or plants at least two feet away to ensure proper airflow.
Dust and vacuum the air vents throughout your home. Obstructed vents make it harder for cool air to circulate efficiently.
Double-check your thermostat to make sure it’s set to “cool” and that the temperature is appropriate. Consider upgrading to a programmable or smart thermostat for added energy savings.
The condensate line can clog over time, leading to water damage or system shutoff. Pour a small amount of vinegar down the line once or twice a year to prevent buildup.
Rattling, buzzing, or clanking sounds can indicate loose components or issues with the motor. While it’s important for you to take note of the noise, a professional should diagnose the cause.
Prevent cool air from escaping by sealing cracks around doors and windows. Also, invest in insulation, if you haven’t already. Your A/C will work less and your home will feel cooler if you optimize the insulation and cool air retention of your home.
Avoid placing lamps or electronics near the thermostat, which can trigger inaccurate temperature readings and unnecessary cooling.
Fans help circulate cool air more effectively. Running fans counterclockwise in the summer helps keep rooms comfortable and reduces the load on your A/C.
Remove and clean registers regularly. Dust buildup can block airflow and reduce system efficiency.
