A visual inspection of the air conditioner is another way to see if the unit is functioning properly. Pools of water or refrigerant shouldn't be present and can indicate leaks from broken lines or clogged drainage holes. It is also a good idea to listen carefully for signs your air conditioner is not working properly.
You need to check the working of the AC thermostat if your split or window AC is not cooling. It is a problem if your air conditioner unit blows out cool air and then lukewarm air. When faced with such a situation, turn the thermostat settings to auto mode. This way the fan works only when the air is being cooled.
A good indicator that your AC works efficiently is if the ambient temperature drops at least one degree every 20 minutes. As an additional note in keeping your AC strong and healthy, refrain from overheating the home. This is not in regards to using the furnace but letting ambient temperature rise too high.
There are a number of reasons why your air conditioner might be running but not cooling. It could be an issue with the thermostat, the compressor, or the evaporator coils. Or, it could simply be clogged with dust and debris, which is preventing it from working properly.
The first thing you'll want to do is check the thermostat. If you have air that's controlled by a thermostat, make sure a faulty thermostat isn't what's causing the problem. In some cases, the batteries may have died or the unit is malfunctioning. Reset the thermostat to see if that turns the AC unit back on.
Some models have the reset button located behind the service panel, which may require tools to remove. Reset buttons are usually red or yellow with a clear “reset” label. On window air conditioners, the reset button is usually on the control panel or located where the power cord connects to the base of the unit.
As mandated by the Ministry of Power, Government of India, all AC manufacturers must fix the default temperature setting at 24°C. So, it is better to set the right temperature at about 24-25 degrees Celsius. This will help in cooling the room faster.
Yes, you should turn off your AC if it's not cooling.
The only way an air conditioner runs out of freon is if there is a leak in the pipes that carry refrigerant from one part of the unit to the other. Freon is not used up: it simply changes state from gas to liquid. Freon should never escape the pipes. However, leaks happen.
What is the lifespan of a window air conditioner? A window air conditioner typically lasts around 8-10 years with proper maintenance, such as regular cleaning and timely servicing.
While a clogged filter is the easiest window AC airflow problem to troubleshoot, it's not the only one. Poor airflow due to a broken fan blade or a faulty fan motor can also result in a lack of cold air blowing from the unit. Issues with the window fan motor are often paired with a clunky noise.
Close Doors
If there are rooms that lead into the room you want to cool down that seem to get hotter than normal, close the door(s) to those rooms. Heat will transfer from room to room if a door is open, so closing any doors in rooms that seem to generate more heat will help.
In general, wall and window air conditioning units with smaller capacities can typically run for up to eight hours at a time before they need to rest. Larger wall and window units have a longer running time of around 10 to 12 hours, depending on their cooling power.
Window AC units can be recharged, but—just like central air—the closed refrigerant system won't need a recharge unless it's damaged. Instead, a well-maintained window air conditioner can last its whole lifespan without needing its refrigerant replenished.
First, check your filters and coils for dirt and debris that may be impeding airflow. Once you've cleaned the filters and coils, run the air conditioner with just the fan so that the ice accumulation can melt off. If the AC still doesn't blow cold air, it could be that refrigerant levels are too low.
Let your Air Conditioning run for about ten minutes then check and record the temperature. After recording your readings, now locate and test the closest return air duct to the unit the exact same way. Once again, leave your Air Conditioning continuously running for 10 minutes before you read your results and record.
