AC Unit Freezing Up – Causes & Fixes
When the air conditioner’s evaporator coil gets too cold, it can cause the unit to freeze up. If you find your AC unit is freezing up, it’s important to act quickly as it could lead to major problems with your unit. Misuse of the air conditioner can create further issues such as a lack of airflow, restricted air supply and higher electricity bills. Here are the potential causes of an AC unit freezing and what you can do in each of those scenarios.
Low Refrigerant Levels
When the refrigerant levels in your AC unit are low, it can cause the evaporator coil to freeze. Low refrigerant levels can be caused by a leak of refrigerant, wrong sizing of an AC unit or an obstruction of refrigerant flow. To diagnose which of these is the problem, contact a trained cooling professional to check your system.
Dirty Coils
A buildup of dirt, dust and other debris on your coils can create an environment for condensation and freezing. Disrupting the air flow can damage not just the coils but other parts of the system as well. To optimize airflow and improve energy efficiency, it is recommended to have a professional clean the coils, condenser and filter regularly.
Clogged Drain Lines
Your AC unit needs to be able to evaporate the moisture that is pulled out of the air. If the drain line is clogged, the air conditioner could freeze up due to ice that is blocking the line, or the cold air within the line might cool the evaporator coils and cause freezing. Again, a trained HVAC technician is best equipped to diagnose and clear any clogged lines.
Thermostat Issues
When the thermostat is off-balance or inaccurate, it can cause the AC unit to freeze up. If the thermostat is set too low, below the temperature of the room, then the cold air from the evaporator coils and other parts of the system can create moisture and cause freezing. It is important to have a technician check the calibration of your thermostat and repair or replace it if it is off-balance.
Poor Airflow in Your Home
If your AC unit is not getting adequate airflow due to dusty air filters and blocked vents, it could cause it to freeze up. Insufficient airflow can lead to poor energy efficiency and poor cooling of your home. Check and replace your air filters every 30-60 days and make sure all return and supply vents are unobstructed.
If your AC unit is freezing up, it is important to consult with a trained cooling professional quickly. They can identify the exact cause of the freeze up and take the best steps to recommission the unit. If left unchecked, the freeze up could cause long-term damage to the unit and lead to a home with inadequate cooling.

AC Unit Freezing Up: Preventive Measures To Avoid Issues
If you are looking to purchase and install an air conditioning unit, freezing up can become a major issue. To prevent AC Unit Freezing Up, there are several recommendations from both local appliance companies and HVAC technicians that should be followed. In this article, we will explore the manufacturer recommendations, as well as the best practices for AC unit freezing up.
Manufacturer Recommendations
Manufacturers of air conditioning units provide specific instructions for installation and maintenance in order to avoid freezing up. For example, manufacturers may recommend installing the unit on level ground to limit the potential for freezing up. Additionally, it is important to ensure there is proper ventilation and a steady supply of clean and dry air to the unit. This can be achieved by frequently changing the air filters and clearing any debris, dirt, or other accumulation that may be blocking the airflow to the machine.
Local Appliance Company Considerations
Local appliance companies that specialize in air conditioning installation generally advise homeowners and businesses to perform regular maintenance on their air conditioner to reduce the risk of freezing up. This typically includes tasks such as inspecting filters, oiling moving parts, and replacing faulty components, as well as checking the unit’s thermostat setting, checking for leaks, and ensuring proper insulation around the unit.
HVAC Technician Recommendations
When a professional, certified HVAC technician is called for AC unit installation, a technician will offer suggestions for maintenance that include checking and testing the Freon levels to ensure that they are within the suggested ranges. Technicians will also recommend having regular tune-ups and preventative maintenance, as well as cleaning the unit on a regular basis. In addition, the technician may suggest testing the wiring and motor, to ensure that the unit is functioning properly and is not susceptible to freezing up.
Best Practices for AC Unit Freezing Up
Regardless of who installs the air conditioning unit, there are a few best practices that should be followed to minimize the chance of freezing up. Most importantly, it is critical to never place the unit in direct sunlight and to always keep the unit out of high-traffic areas. Secondly, homeowners and businesses should inspect the unit frequently and make sure it is clean and free of debris. Additionally, replacing air filters on a regular basis can help to promote proper air flow and reduce the chance of the unit freezing up.
Finally, calling a local, reputable air conditioning company or HVAC technician when the unit is not functioning properly can help to identify any potential issues and remedy them before significant damage is done. Taking proactive steps to ensure the unit is properly installed and maintained can help to avoid costly repairs and potentially even prevent AC unit freezing up.
Average Repair Cost for AC Unit Freezing Up
Repair costs for an AC unit freezing up vary depending on severity. Generally, DIY repairs can be done for as little as $50, while professional repair and installation can run upwards of $200. A minimum repair or installation cost in California may be 20% higher, around $240.

FAQ – AC Unit Freezing Up – Causes & Fixes
What Causes an AC Unit to Freeze Up?
The most common cause for an AC unit to freeze up is a lack of airflow due to dirty or blocked air filters. The buildup of dirt, dust, and debris can create an insulation-like barrier that minimizes air flow going into the air condenser. Other common causes for an AC to freeze up are a malfunctioning fan or an older AC unit that is low on refrigerant.
How Do I Fix an AC That is Freezing Up?
Start by inspecting your air filters and ductwork for dirt and debris. Clean or replace the air filter as needed. If you have an older AC unit, check to make sure the refrigerant levels are optimal. If you have a malfunctioning fan, replace any worn parts and lubricate any moving parts to restore efficient airflow.
How Do I Keep My AC Unit From Freezing Up Again?
To keep your AC unit from freezing up again, keep the air filters clean and replace them as recommended. Replace the air filters at least every three months, and adjust the thermostat settings to the recommended level. Additionally, it is important to maintain your system and have a professional technician inspect the air condenser regularly.
Can I Fix a Freezing AC Unit on My Own?
If you have the correct tools and knowledge to safely work with an AC unit, you may be able to fix a freezing AC unit on your own. However, it is generally recommended to contact a reliable technician to safely inspect and diagnose the issue and make any necessary repairs.
