How to Save Your AC’s Energy and Increase Efficiency

Please share

An air conditioner operating to its optimal energy efficiency level is incredibly beneficial that includes:

  • An increased lifespan of your Air Conditioning Unit
  • Comfortable home in a consistent air temperature
  • Decreasing energy bills

But in order to achieve that you have to follow certain how-to tips. Read further on to know the basic tips on how to efficiently boost your cooling system and save your energy cost.

AC's Energy and Increase Efficiency


Boost your Air Conditioner and Heat Pumps by setting your thermostat right

Set it between 75 to 80 degrees when you are at home and 80 degrees and above up to 85 degrees when you are away. In that way you can save up 4% on cooling cost.

If you have a programmable thermostat, set it to allow an increase of 5 degrees when you are away and return to normal level when you are at home. Or you can also set it to return to a normal level during off-peak hours.

Turn the Air Conditioning fan to Auto Mode to save up your monthly cost

Turning your fan to Auto Mode actually turn the motor off whenever the unit is not cooling. That would save your bills around $18 each month, thus saving up on energy cost.

Use exhaust fans during moisture-producing activities. Cooking, bathing, washing, and similar activities produce a lot of moisture inside the home. Exhaust that moisture directly outdoors using a fan. Similarly, avoid drying clothes indoors except with a clothes dryer that is exhausted directly outdoors.

Buying or Replacing an Air Conditioning Unit

If you have plans on replacing your cooling system, make sure you buy a higher SEER (Seasonal Energy Efficiency Ratio) unit. Ask an HVAC Contractor for the right efficiency level for your home.

If you want to stick to EER (Energy Efficiency Ratio), remember that the rating should be above 10 while the SEER should be above 12 especially if it’s for central air conditioners.

If you are replacing an old central air conditioning unit, replacing the outdoor compressor with a high-efficiency unit is your best option. But make sure it is compatible and it will match your old unit.

Make sure you are buying the right size Air Conditioning Unit for your home. Larger unit usually cause frequent cycling that brings inefficient operation and higher operating cost.

Also consider an Air Conditioner with an inverter or variable speed drive included in the motor that controls the compressors. This is very efficient in a typical household operating part load.

Maintenance on Air Conditioner components

Clean up obstruction and remove any debris around the outdoor air conditioning unit then replace disposable filters that force the equipment to work harder.

If you have a permanent air filter, clean it once a month to cut off your monthly energy bills.

If you have an evaporative cooler, don’t run it together with your air conditioner in the same day. Evaporative cooler increases humidity while air conditioner removes humidity so it is logically better to run one component at a time specifically to what you think is needed for certain times.

Seal air duct and insulate the ducts that run though the areas that does not require temperature control.

You can also improve the efficiency by using fans to increase your cooling capacity. You can place them near the vents to help increase the circulation of cool air inside your home.

Schedule a maintenance service once or twice a year by a certified contractor to maintain efficiency. Make a checklist of what the contractor should check that will include:

  • Checking the correct amount of refrigerant
  • Testing refrigerant leaks using a leak detector
  • Capturing any refrigerant that must be evacuated from the system, instead of illegally releasing it to the atmosphere
  • Checking and sealing duct leakage in central systems
  • Measuring airflow through the evaporator coil
  • Verifying the correct electric control sequence and make sure that the heating system and cooling system cannot operate simultaneously
  • Inspecting electric terminals, clean and tighten connections, and apply a non-conductive coating if necessary
  • Oiling motors and checking belts for tightness and wear
  • Checking the accuracy of the thermostat.

Make sure you consult your HVAC contractor if you are not sure of what you are doing. If there really nothing much to fix, ask for better advice on how to ensure your system is running efficiently and it saves your energy cost.
