The ultimate purpose of installing an air conditioner in your home is to provide a comfortable temperature inside your home. Air conditioner freezing up is quite a natural scenario. At some point, an AC unit may freeze up when the balance between maintaining coolness at home and making sure that the machine is functioning is not kept. When the AC unit freezes up, it is very important to check the flow of air, have the refrigerant carefully checked, and operating it less even in cool weather.
Checking the Air Flow
If your air conditioner starts to freeze up, it is very important to check and make sure that air flow is properly observed. If air cannot pass thoroughly through your AC unit, the tendency is, the coil may freeze. Particles in the air filter may block the flow of air as well. To solve this issue, it is important to check the filter, replacing it when necessary.
The AC coils often freeze up when air flow is restricted
Regularly replacing the filter per the instructions of the manufacturers will prevent it from being blocked again. However, if your air duct system is not large enough to allow sufficient air flow through the coil, functionality may also be sacrificed. Therefore, it is important to have the ducts cleaned especially if the freezing up has started already.
On the other hand, if you think you are not able to do the process yourself, it may be wise to hire the professional services of an HVAC contractor. They will inspect the ducts and see to it that the size is enough for your cooling system.
Charging the Refrigerant
Appropriately charged refrigerant can create an optimal environment for the AC unit. If the unit is not accordingly charged, the unit may tend to freeze up. For this task, only a professional AC contractor can charge and check your AC refrigerant. If you have made sure that this is the reason why your AC is freezing up, calling a professional to check on your refrigerant is your next best option.
Temperature Making the Air Conditioner Freeze Up
During the times when the weather is cooler, the air conditioner unit may end up not working well if it is situated outside. If you notice that the air conditioner freezes up lower than 60 degrees Fahrenheit, it is better to call for the assistance of an HVAC professional who will install a control for the temperature. If you are looking for an alternative option, you may also turn the AC unit off if the temperature outside is cool, such as, during night time. Also, it may be best to open windows rather than using your AC unit for cooling.
Check the Blower Fan
Observe intently the movement of the blower fan. It should be transporting the air from the inner vents. If the fan is not working, make sure to stop the unit immediately. At this point, the motor of the blower’s fan may need to be replaced. At the same time, you may need to check all the inner vents of the system in order to make sure that there is no hindrance in the front area of the registers.
To check the inner vents, you need to take a look inside. Open all the exhaust vents on your air conditioning system. Closing them will only restrict the flow of air through the coil. It may also be the reason of the freezing of the coil. If the fan operates accordingly and the vents are already unrestricted, make sure to check the outer part of the outer coil.
If your air conditioning unit is freezing up, it may also be an indication that the coil is already dirty. Dirty coils need to be replaced. For coil replacement, you need to ask the assistance of a professional to do the task. Also, an air conditioning unit may freeze up if the blower has a problem. This too, can only be diagnosed and corrected by a professional HVAC repair person.
