What to Do When Your AC Unit Freezes Up.
the first step to fixing your frozen AC is to turn the system off,if your AC system is still trying to cool,it will continue forming frost .In severe cases,you may even want to turn your thermostat to the heat setting to speed up the thawing.
While your Air conditioner is thawing,be sure to watch the water levels in the unit.If the drain pan inside the evaporator coil overflows, you can experience water damage in your air conditioner.
Why is My Air Conditioner freezing?
1.Damage Blower Fan Or parts malfunction.
your Air conditioners blower fan helps get cold air where it needs to go and get the warm air outside.As the air cool inside of your air conditioner,it becomes denser and doesn't travel as well.The blowers fan help move cold air by hot air out of your home,which the denser cold air moves to to replace.
How effectively your AC can crate cool air and push it out to you is 100% dependent on your machine having the correct balance of airflow and air pressure..Sometimes your blower fan can break, or become damaged during normal operation.When your blower fan is on the fritz,that significantly changes the airflow inside of your air handler. Too much condensation will build up on the coils,and the water droplets will not evaporate or drain properly.
Without the hot air moving over the proper parts,a broken blower fan can also cause refrigerant line to freeze too.If your refrigerant line is frozen,be careful,The freeze can easily back up all the way to your condenser unit outside,causing problems.
2.Dirty Coils
The most common causes of AC freezes is a dirty air conditioner coil.Again,ice obstruct the proper air flow of your system-so what starts off a little bit of the air,which makes condensation that builds up on the coils.
Dirty coils can cause freezing because the layer of dirt on top of the coils can prevent them from absorbing the water fast enough. bi-annual check ups from your local Aircon tech professional can keep your AC;s coils Clean.
3.Poor Airflow
If your AC cant get enough air,then there wont be enough heat from the warn air in your home,to prevent the condensation on the coil from turning into ice.Check in Replace your air filters first. Even if your air filters are clean,poor air flow still the problems.
Inspect of the air vent in your home,holding your hand in front of them to fell for air leaking from the sides of the grate.You'll want to also look for blocked ducts,closed or blocked grates,and closed dampers.
4.Low Refrigerant
some times AC freezes ups can be caused of the refrigerant also known as R22 Refrigerant has different physical properties at various levels of pressure,In a properly functioning system,the way the refrigerant is passed through the lines it is at a temperature where condensation may form on the outside of the line.
If sometimes happens and the pressure in your system changes,the pressure changes changes can cause the R22 to act differently.As the moist ,warm air from your house moves over the evaporator,the moisture will begin to form.You might not notice a change in the performance of your system with minor frost,but too much ice will affected the airflow.
Eventually,the ice will act as an insulator and prevent the air conditioning system from the functioning properly ,and the R22 refrigerant will evaporate faster.when the refrigerant level gets to low,your air conditioner cant freezes the line.The ice may melt,and then you'll notice the air flow
behavior has stopped- but you're not getting any cooling at all from the system.
