It’s easy to take your air conditioner for granted until it stops functioning properly. A common cause for a malfunctioning air conditioner is freezing. Contrary to how this may sound, this is not an issue that happens in the wintertime.
Rather, this is caused by issues with how your system functions while it runs — usually at the height of summer. Fortunately, Air Tech of Conroe is here to assist you with solving this issue and getting your AC up and running again in no time.
What Does It Mean To Have a Frozen Air Conditioner?
- A “frozen AC” is a term used when ice forms on your unit’s evaporator coil. An interruption in the heat transfer process typically causes this problem. Various issues within the system can cause this to occur, including:
- Low refrigerant levels — If the AC is low on refrigerant, it may indicate a leak and inadequate cooling.
- Dirty evaporator coil — An accumulation of dirt and debris on the evaporator coil makes it difficult for the refrigerant to absorb heat, thus limiting the heat transfer and causing freezing.
- Problems with the condenser unit — Common problems with the condenser unit include a malfunctioning fan, clogged coils or other damage to the system.
- Faulty thermostat — An incorrectly calibrated or faulty thermostat may cause the AC to run constantly and causes freezing.
- Improperly functioning blower motor — An inefficient blower motor can result in insufficient airflow, causing the evaporator coil to freeze.
You should address a frozen AC as soon as possible to prevent further damage. If you notice that your AC is frozen, immediately turn it off. Then, you can try to correct the problem or contact a professional.
How To Repair A Frozen Air Conditioner
The first step is to turn off the air conditioner. Continuing to run a frozen AC can cause further damage. Ensure that the thermostat is set to the appropriate temperature and mode (cooling mode).
Incorrect settings can cause the AC to run excessively and lead to a breakdown. Completely thaw your air conditioner before turning the system back on. This may take several hours or even overnight.
Solutions For The Outdoor Unit
Problems with the outdoor unit can cause the air conditioner to freeze. Check the air filter and replace it if it’s dirty or clogged. A dirty or clogged air filter can restrict airflow, causing the evaporator coils to freeze.
Make sure no obstructions are blocking the airflow around the AC unit inside and outside the house. Trim back any vegetation or objects that might be limiting airflow. Ensure the blower fan is functioning well and there are no issues with the motor or belts.
Inspect the ductwork for any leaks or blockages. Leaks can cause warm, humid air to enter the system. Issues with the blower fan or ductwork can cause freezing.
Some solutions to a frozen air conditioner are more advanced and require the help of one of our technicians. Low refrigerant levels can cause the evaporator coils to freeze. If you suspect this is the issue, you need to call a professional HVAC technician to inspect and refill the refrigerant. Handling refrigerants requires special equipment and expertise.
The AC can freeze if the coils are dirty or dusty. Our technicians can clean the coils with a soft brush or a cleaning solution. When in doubt, contact a professional HVAC repair.
