Rising temperatures and skyrocketing utility bills in the summer may leave you wondering how to make your air conditioner more efficient. Everything from the size of the unit to how you use it can impact how much energy it uses.
1. Choose the Proper Size
Buying the right size air conditioning unit is an important factor in energy efficiency. If the AC is too small for the space, it’ll run constantly to reach the set temperature. In some cases, it might never get cool enough. The constant running increases energy consumption and can overwork the unit, causing it to die sooner. An oversized unit might start and stop frequently because it’s overpowered, which can also hurt energy efficiency.
2. Clean or Replace the Filters
AC units include air filters that need to be replaced periodically for efficient operation. If you skip this maintenance step, the air filters become clogged, making it difficult for the air to pass. This makes the unit work harder and use more energy. The name of the game with air conditioning is air flow.
3. Clean the AC Unit
Don’t forget to clean the rest of the AC unit as well. Be sure clean the exterior unit, which can get clogged with leaves and other debris. Make sure the drain line is clean and free of obstructions to allow the condensation to flow freely.
4. Limit the Use of Hot Appliances
If you run heat-generating appliances, such as your stove, clothes dryer and hairdryer. You’ll increase the overall temperature inside your home. This forces your air conditioner to work harder to cool your home. Limit how much you use these appliances and use them during the coolest part of the day when possible.
5. Seal Up Your Home
Gaps and leaks throughout your home make it less efficient. The cooler air that your AC produces can escape, causing the air conditioner to work harder and run longer to keep your house comfortable. Seal those gaps and cracks, which often happen around windows, in foundations or where things like pipes and wires enter your home. Keep your doors and windows closed while you’re running your air conditioner for increased efficiency.
6. Adjust Your Thermostat
You might prefer your room chilly, but bumping up the thermostat by a few degrees can save energy. You can also program your thermostat to run at a warmer temperature while you’re gone.
7. Keep Air Moving
air movement around the air conditioning unit helps it run more efficiently. While shade over your outdoor condenser can help it work more efficiently, you don’t want shrubs or trees so close to the unit that they block airflow. Cut back vegetation if necessary to leave a minimum of 2 feet of clearance around the air conditioner.
8. Schedule Professional Maintenance
Have an HVAC professional inspect it at least once per year. The technician will deep clean the unit and look for potential issues that you can repair before they become major problems.
9. Block the Sunlight
Your air conditioning can work more efficiently when you block sunlight from entering your home. Close your window treatments during the part of the day when the sunlight hits the windows. This prevents the sun from making your home hotter, which makes the AC work overtime and use more energy.
10. Insulate Ductwork
If you’re trying to figure out how to make your air conditioner more efficient with a central air system, insulate the ductwork that’s exposed. Use duct-sealing tape to repair any gaps before adding the layer of insulation. This helps reduce the loss of cooled air as it travels through the ducts to the registers throughout your home.
