When it comes to cooling a house, air conditioners are typically the first line of defense against hot, muggy weather. However, relying on only your home AC might be keeping you from optimizing the cooling potential of your home.

From encouraging better airflow to maintaining your HVAC system year-round, there are plenty of ways to improve cooling efficiency and prevent any unwanted surprises when the first summer electricity bill arrives.

What Are the Benefits of Running an AC Efficiently?

A reliable, efficient air conditioner can save you money and reduce overall electricity use in your home. It also helps keep your home cool in summer and reduces unwanted temperature fluctuations because an efficient AC runs more smoothly and consistently.

Maintaining an efficient air conditioning system helps keep you, your family and your pets comfortable and healthy. Cooler indoor temperatures discourage pests, which often prefer warm, damp conditions, and many people sleep better in a cooler room.

What Are Some Ways to Make Sure Your AC Is Operating at Peak Efficiency?

The first step to making sure your AC is operating at peak efficiency is to get regular HVAC tune-ups that check your unit for any problems. Some things a technician might look at during an air conditioning system tune-up include whether there are any leaks in the duct system, obstructions in the vents or damaged components of the AC unit itself.

A technician performing a checkup on your air conditioning system might also put in new air filters, but you might also want to perform this maintenance task between regular checkups. Changing your air conditioner filters every 3 months improves efficiency. Households with pets may want to swap a new filter in more frequently.

A programmable thermostat can automatically adjust the temperature in your home during specific times of the day, ensuring you aren't cooling an empty house. Smart thermostats let you adjust the temperature from a phone or tablet, so you can turn on the AC before you head home from work or switch from night to day operation even if you forgot to change the setting before you left.

Ensuring Optimal Air Conditioning Efficiency With Warm-Weather Home Design

Your air conditioning unit works hard, but you can help reduce wear and tear by optimizing your home for efficient cooling. Keep warm air out of your home and reduce cool air leaks by sealing doors and windows. This type of weather stripping also helps control moisture in the home and blocks out dust and debris.

Installing blinds or blackout curtains, especially on north- and west-facing windows, lets you control how much sunlight gets into your home. You can also plant trees or tall bushes on those sides of your home to provide shade from the harsh midday sun. Installing awnings above your windows can also reduce the heat coming into your home.

Appliances can be a source of heat in your home, and the heat they generate could be making your AC work harder. Ovens and stoves are especially known for excess heat generation, so reducing their use in summer helps. Opt for no-cook foods, such as salads and sandwiches, instead of dishes that require long cooking times. Dishwashers, washing machines, clothing dryers and electronic devices also produce heat, even when they aren't in use. Limit the use of large appliances to evenings after the sun has set, and unplug unused appliances to prevent excess heat generation.

Some appliances help improve cooling efficiency. A dehumidifier dries out the air in your home, which makes you feel cooler and reduces how hard your AC has to work. Portable fans, ceiling fans and box fans all make you feel cooler and circulate air, so you can keep your AC at a higher temperature than you might need without improved circulation.

Cooling a House Without Turning on the AC

When the weather is mild, you may not need to turn on your AC at all. Utilizing open windows to bring in cooler outside air and turning on ceiling fans to increase airflow can help you save on energy costs. When using open windows to reduce heat in the home, choosing windows on opposite ends of the house creates an efficient cross breeze that pulls cool air through all the rooms.
