AC Freezing Up? – Troubleshooting Tips
It’s frustrating when your air conditioner suddenly stops working, or worse yet, freezes up. Nothing is worse than not being able to stay cool during the hottest days of summer. If you’re dealing with an AC freezing up, read the below troubleshooting tips to help you get your unit back up and running in no time.
Check Air Filters
The first thing you should check when your AC is freezing up is the air filter. The air filter is responsible for collecting dust and other particles that could harm the HVAC system. If the filter is clogged, it can result in a lack of airflow that could potentially cause the unit to cool too quickly, resulting in a frozen coil.
In order to prevent a frozen coil, be sure to change the air filter according to the manufacturer’s instructions. It’s typically recommended you change the filter once a month during peak cooling season. Not only will this help to keep your AC from freezing up, it will also help keep energy costs down.
Clean the Condensate Drain Line
Clogged condensate drain lines can also contribute to an AC freezing up. Your air conditioner produces condensation as it cools your home, and the condensate drain line is responsible for carrying the water away from your HVAC unit. When the condensate line becomes clogged with dirt, dust, or other debris, it can cause water to back up and freeze, resulting in a frozen coil.
You can clean the condensate drain line in a few easy steps. First, locate the drain line and remove any visible dirt and debris. Next, pour a mixture of bleach and water into the drain and allow it to sit for 30 minutes. Last, flush the line with hot water. Doing so will help to prevent your AC unit from freezing up.
Check the Evaporator Coil
A frozen evaporator coil is often the culprit when it comes to an AC freezing up. The evaporator coil is responsible for cooling down the air as it enters your home. If the evaporator coil is dirty, it can cause air to flow too slowly or not at all. This can lead to a buildup of ice, resulting in a frozen coil.
Fortunately, there is a simple way to clean the evaporator coil. You’ll need a few basic cleaning supplies – a screwdriver, protective goggles, a bucket, and a vacuum cleaner. First, turn off your AC unit and remove the cover on the evaporator coil. Next, use a vacuum cleaner to remove dust and other debris from the coil. Finally, use a bucket of warm water and a soft bristle brush to wipe away any remaining debris.
Call a Professional
If the above troubleshooting tips don’t work or you’re feeling intimidated by the process, you can always call a reliable appliance repair company. A qualified technician can quickly diagnose the problem, fix the issue, and prevent your AC from freezing up for the long term.

Preventive Action to Avoid AC Freezing Up Issues
Air Conditioning (AC) units often freeze up due to various reasons ranging from clogged air filters to low refrigerant levels. Taking preventive action is the best way to avoid AC freezing up issues. The following are some of the manufacturer’s, appliance companies’, and HVAC technicians’ recommendations for avoiding AC freezing up:
Change Filters Regularly
Air filters should be changed or cleaned every month to promote good air flow and to prevent the AC unit from freezing up. Dirty air filters can reduce the airflow and restrict the flow of cold air needed to keep the AC unit cool.
Check Refrigerant Levels
The refrigerant level should be checked at least twice a year, preferably in the spring and fall. Low refrigerant levels can cause the AC to freeze up, either due to clogs or a leak.
Check for any Leaks
Any leaks in the lines connecting the AC unit should be checked for and repaired as soon as possible. Leaks can cause the AC to freeze up, leading to additional problems and costly repairs.
Ensure Proper Installation
Proper installation is an important factor in preventing AC freezing up. An HVAC technician should be consulted when installing an AC unit and all components should be inspected for proper alignment.
Keep Air Conditioner Clean
Leaves, debris, and other particles should be kept away from the AC unit to avoid clogging the air filters. Regularly brushing dirt and dust off the outside of the AC unit, as well as cleaning the condenser and evaporator coils, will help to keep the AC unit running smoothly and prevent it from freezing up.
Check Condensate Lines
Condensate lines carry away any moisture produced by the AC unit and should be checked regularly to make sure they are clean and clear. Clogged condensate lines can cause the AC unit to freeze up and potentially cause water damage if the clog is not removed.
Fix any Failing Components
Any components in the AC system that are faulty or not working properly should be repaired or replaced as soon as possible. This includes the fan motors, condenser fan, or any other components that are not functioning correctly.
Install an Electronic Programmable Thermostat
An electronic programmable thermostat can help to prevent the AC unit from freezing up as it can be set to operate more efficiently and effectively. Additionally, it can help reduce energy costs and keep the AC unit running longer.
Schedule Routine Maintenance
Having routine maintenance performed on the AC unit at least once a year can help to prevent it from freezing up. A qualified HVAC technician should be called to inspect the AC unit and perform any necessary maintenance or repairs.
Taking preventive action is the best way to avoid AC freezing up issues. From changing the air filters regularly and checking the refrigerant levels to keeping the AC unit clean and scheduling routine maintenance, these manufacturer’s, appliance companies’, and HVAC technicians’ recommendations should be adhered to in order to keep the AC unit running efficiently and avoid costly repairs. If you suspect an AC freezing up issue, contact a qualified local Reliable Air Conditioning & Heating technician at (866) 311-8590 for an evaluation and repair.
Average Repair Costs for AC Freezing Up
The average repair cost of an air conditioning unit freezing up will depend largely on the severity of the issue, the parts that need to be replaced, and the location. On average, homeowners should be prepared to spend $200 to $800 for minor repairs and up to $2,000 or more if a major part needs to be replaced. Prices may be 20% higher in California.
To fix an AC unit freezing up, repairs can range from cleaning the condenser coils, replacing the thermostat, or replacing the capacitor or compressor. If a minor issue is found, you may only need to replace one or two parts, but if a large part needs to be replaced or installed, the cost could be much higher.
