You can vacuum dust and any debris away from indoor supply vents to help maintain steady airflow from your system. Also, keep items like blinds, furniture and toys away from blocking the vents.
Check the air filter once per month and clean/replace it as needed. This is especially important during the summer when dust and allergens circulate. If the filter becomes clogged, your system will have to work harder to supply the same amount of cool air. Cleaning/replacing filters is one of the easiest and most effective methods of conserving energy and saving money. And much like changing the oil in your car, it’s a critical step in maintaining your system’s long-term health.
A great home improvement idea is to install home window film or tint to the insides of your windows. Not only can it help keep your house cooler in the summer.
Running your dryer will cause warm air to be drawn into your home and using your oven will add additional warm air to your home, causing your air conditioner to have to work harder.
Keep plants, shrubs, and other landscaping about 2 to 4 feet away from your outdoor unit to ensure adequate airflow.
You want your cold air to stay in and hot air to stay out. Some basic weatherization steps can prevent air loss when you need cool air the most. Seal air leaks with caulking and weather-stripping. Add insulation around air conditioning ducts.
Air conditioners with proper shading can run more efficiently. Air in a shaded space is cooler than the surrounding air, meaning the A/C will have an easier time cooling the air.
During the night, you don’t require the same level of conscious cool. Try turning your AC down (so it is running less) during your sleep hours or, if your unit has one, utilize the “sleep mode” which lowers the output on a timer.
