Tips for Using Your Air Conditioner Efficiently

July 29, 2022

Learn how to enjoy cool air in your home this summer while using your air conditioner efficiently and avoiding a large utility bill.

According to the website happyhill.com, “Your air conditioning system could account for approximately 12% of your total annual home energy expenditures and up to 70% during the hotter summer months. The HVAC is the biggest energy user in your entire house.”

Follow these tips for using your air conditioner efficiently:

Keep cool air in your home

If cool air is escaping your home, you are using your air conditioner inefficiently. Your utility bill will be higher in general, and your air conditioner will run more than would otherwise be needed.

Prevent cool air from escaping around windows, doors, and into your attic by checking and repairing seals. Keep doors and windows closed. If you want to air out your home, turn your air conditioner off first.

Raise your thermostat

One of the simplest tips for using your air conditioner efficiently is to raise your thermostat a few degrees. This lets your air conditioner work less while still keeping you comfortable. Consider a programmable thermostat so you can easily cool your home only when needed.

GreenerIdeal.com explains that “if you have a time-enabled thermostat, you can even set it to get warmer in the middle of the night so you can fall asleep comfortably and still wake up feeling refreshed.
Even a small window of time when you use less A/C will make a difference on your energy bill...”

Keep heat away from your thermostat

To use your air conditioner efficiently, make sure appliances that produce heat are not near your thermostat. If your thermostat is in a hot part of your home, your air conditioner will be on longer than it needs to be. Your thermostat may need to be moved if it was installed near a sunny window or next to an appliance, otherwise, your cooling costs will be high. You can also try increasing the temperature on your thermostat.

Clean your vents

Keeping your vents free of debris is one of the best ways to boost your air conditioner’s efficiency. Check for dirt, dust, and pet hair around vents and replace air filters if you use them. Make sure vents are not blocked by furniture, rugs, or other items. Have the ducts cleaned regularly.

Do not use heat-producing appliances

Avoid using your oven or dryer on hot days to stop your air conditioner from having to work harder to compensate for the heat they create.

Install a zoning system

Consider zoning controls so each room can be at its optimal temperature. “With these, you can divide your home into groups of rooms or individual rooms to achieve customized cooling levels. By controlling temperature like this, you can actually improve the efficiency of your system,” explains Happy Hiller.

Cover your windows

Close your blinds or curtains during the day to keep the sun out and reduce how much heat comes into your home. You can reopen them when you come home from work in the late afternoon.

Change your air conditioner's filter

Changing the filter is an important part of using your air conditioner efficiently. A dirty filter will reduce the air quality in your home and will make your A/C unit worker harder. Anytyme.com Plumbing, Heating, and Air explains that keeping the filter clean can lower your air conditioner’s energy consumption by 5% to 15%.

Clean the condenser unit and create shade around it. Check the outdoor condenser unit for debris and have a professional clean the condenser itself. It should be in a shady area; if it is not, create shade around it without obstructing the airflow.

Watch for signs that your air conditioner is becoming inefficient.

If it is not operating at optimal efficiency, you may notice these signs:

• Your utility bill is higher than normal. If your usage and costs increase, have your air conditioning system examined by a professional.
• Your thermostat cycles on and off often. If this happens, it may need to be replaced because of wear and tear on its internal mechanism. Your system may also cycle too often because of damage to the compressor; you may need a professional to determine the cause.
