If you live in a climate where the temperature goes up frequently, then an AC can make the living conditions much more pleasant and comfortable˳ As is the case with many pieces of technology, an AC also loses if proper functioning after a period of use˳ It is essential that you keep on gauging the efficiency of your AC so that if issues arise, they can be rectified before it’s too late˳
Here are some tips on how to tell if your air conditioner is running efficiently˳
Prepare your AC for testing
You should replace your furnace filter and then remove all vent coverings˳ This is necessary to ensure that airflow is smooth and not restricted˳ Just pull out the loose vents or use a tool to pull out any tight-fitted covers˳ Sometimes you might need help from an AC maintenance company if you need to remove the vents which are placed in an outdoor unit˳ They can do this job more efficiently and safely˳
Determine the different ducts of the AC
You should know which are the supply and the return ducts in your AC˳ In order to determine this, place a tissue over each duct˳ If the tissue starts flying away from the duct, then that is your supply duct, whereas if the tissue paper is sucked in, then that is your return duct˳
Check the Temperature of Both Ducts
You can do this in some very simple steps˳ Turn on your AC, and let it run for at least 15 minutes˳ Then take a thermometer and place it inside the supply duct˳ Check if the thermometer is below the current room temperature to ensure a correct reading˳ You can use any thermometer, even a refrigerator thermometer will work˳ Remember that the supply duct is that part of the AC that throws cool air into your room˳ Keep the thermometer over there for 10 minutes˳ Note down this temperature˳
Now go to the second step and keep the same thermometer on the return vent, again for ten minutes˳ As said before, the return vent is that part of the AC which pulls in the room air and delivers it to the HVAC system˳ Note this reading too˳
Now subtract both the readings to calculate your results˳
Results Will Tell the Efficiency of Your AC
If there is a difference of 20 degrees between your supply and return ducts, then your AC is working fine˳ But if this temperature is less than 20 degrees, then this can tell you that your AC is not working efficiently˳ There can be many possibilities of this problem˳ One may be that there is a leak in the system, or another may be that you need to replace the HVAC filter˳
