Your home's air conditioner uses a coolant to lower the temperature of the air that travels through it. Ideally, this coolant should last for the life of the unit. However, the coolant can deplete in certain instances. Wear and tear, damage from an accident or contaminants can all lead to coolant depletion.
This loss of coolant is something you can check for on your own. Go through the following steps to determine if your ac is out of coolant:
Reset The AC
You can reset it directly at the unit or you can flip the circuit breaker that controls the air conditioner. This helps by resetting all of the electrical components of the unit.
Check The Thermostat
Sometimes the thermostat can accumulate dust and grime inside. Begin by pulling off the cover of the thermostat. If it is dusty inside, blow or wipe it out. This ensures a good connection for the temperature controls.
Now ramp up the temperature to 80 degrees or higher. Let it stay there for at least half an hour. Then lower it back down to around 60 degrees. This should cause the unit to turn on.
Check The Vents
After about 15 minutes, the air conditioner should be blowing cool air. Go to the vents and feel the air that is coming out. If it is warm or room temperature, you could be out of coolant.
Look For Frost Buildup
Usually when coolant depletes in an air conditioner, it happens slowly. When it does so, it will leave signs in the form of frost. Anywhere it is coming out of the unit – around connectors, hoses, tubes, where the coolant tank connects to the unit – you will notice frost. Of course, it could have all leaked out a while ago. But usually the leak is slow enough that you will see some frost accumulation somewhere on the unit.
Call In A Contractor
If your ac is not cooling properly due to lost coolant, you will need to call in an ac installation technician to refill it or replace the unit. He or she can quickly determine if lost coolant is your issue, and tell you what you need to do next.
If the damage that led to the leak is significant enough, you may need to replace the unit. This can be the case when the unit is older, too. However, the tech may be able to give you a quick refill, and you get you back up and running surprisingly fast. To learn more, visit Lindsey Refrigeration and AC.Share
