Even homes with adequately functioning air conditioners can experience frozen AC line during freezing weather. If you live in an area prone to freezing temperatures or have an older air conditioning system, you may want to take steps to prevent your lines from freezing and avoid expensive repairs later on. Read on for more information about your frozen ac line, what causes it, and how you can prevent it from happening again.

What are air conditioner lines?

What are air conditioner lines?

Air conditioner lines carry water from your AC unit’s indoor unit to its outdoor condenser unit. They are responsible for cooling your home by releasing the water cooled by the AC unit. Air conditioner lines are typically made from copper or fiberglass. Copper air conditioner lines are the most common type

Fiberglass air conditioner lines feature a non-corrosive interior coating that prevents rust from forming. They’re usually used in AC systems in very wet or salty environments, such as coastal areas or near rivers or lakes. Copper is also in high demand and is widely available in the United States.

How to know that frozen ac unit or not?

How to tell if ac is frozen?

You can usually tell if your air conditioner’s lines are frozen by seeing if the water stops flowing. Frozen lines won’t transfer the water from your AC unit indoors to its outdoor condenser unit, so you may notice less water in your backyard and fewer drips from your AC exterior. If this happens, you’ll need to thaw your lines before the water flow returns to normal.

Why air conditioner lines are frozen

why air conditioner lines are frozen

AC line has frozen when the water inside them freezes and expands. This happens when the water in the lines is below 32 degrees Fahrenheit. As the water in the lines cools, it becomes less dense, expanding and pushing the surrounding ice out of the line. If the cooling water is frozen, it cannot leave the line. 

When the surrounding water freezes and expands, it pushes against the frozen cooling water, increasing the pressure inside the lines and making them burst. This can cause extensive damage to your AC system and may result in the need for expensive air conditioning repair or even the need for a replacement HVAC system.

Warning Signs If your air conditioner is older than ten years, you may want to take extra steps to prevent frozen AC lines. Newer units tend to be better insulated and better suited to cold weather, but older units may be more susceptible to freezing.

Ice Or Frost Forming On Your AC Unit

Install Air Conditioner Blankets

Air conditioner blankets are used to insulate outdoor units from extreme temperatures. They’re made of a thick, insulating material that traps warm air and covers the entire condenser unit. They help prevent the outdoor coils from freezing and reduce energy use. You can either buy an air conditioner blanket or make one using a tarp.

Check and drain the condenser coil.

If the outdoor unit freezes, check and drain the condenser coil before you start thawing the unit. First, turn off the electricity and then be patient until it dies.

Then, open the outdoor unit and use a garden hose to spray water into the unit. This will drain the water from the coil.

Once you’ve drained the water from the outdoor unit, you need to thaw the coil. You can either use a coat hanger and some warm water or call a professional for assistance. After you’ve melted the coil, you can start the unit up again.

Installing an intermittent condenser fan

When cold weather sets in, an intermittent condenser fan on your AC unit can help to push cold air back into your home, preventing the lines from freezing, this can help reduce the risk of your AC lines freezing even when the temperature outside is well below freezing.

This device attaches to your air conditioning unit and cycles on and off as needed, pushing cool air back into your home. Before installing an intermittent condenser fan, ensure your AC unit is correctly installed and maintained and that nothing obstructs the flow of air from the unit. Installing an intermittent condenser fan on an improperly installed AC unit may cause more damage to your unit.

Solutions To Air Conditioner Line Freeze-Ups

A frozen line in your air conditioner can be a common problem. However, if you don’t know how to prevent it from happening, there are some things you can do to fix it yourself. This article will help you identify the causes and solutions for frozen ac line so that they don’t continue causing problems with your air conditioning.

Dirty Air Filter

1- Check The Dirty Air Filter

When you use your air conditioning, it uses filters. If they become clogged, they can’t do their job. This causes terrible airflow through your air vents and can lead to other issues like increased energy usage. You can check on your air filter daily to make sure it isn’t covered with dirt. If it is, you can clean or replace it. Cleaning it is the easiest way to check it. If there is a dirty filter, you’ll need to replace it. This will improve your indoor air quality.

Use High-Quality Air Filters

Use High-Quality Air Filters

Air filters are essential for your AC system. They clean the air that passes through your supply vents to keep your indoor air fresh and clean. If your air conditioning has a low-quality air filter, it can cause more energy and more labor from your air conditioner. This can cause your AC to have high energy bills. When you use high-quality air filters, they make your AC operate more effectively. This can lower your energy bills.

Maintain the Evaporator Coils

3- Check The Evaporator Coil

There are generally two types of evaporator coils in air conditioners. The most common is a serpentine evaporator coil, it is made up of a number of tubes (ac pipe). Air passes through these tubes and condenses, and turns into water vapor. A second type is a flat coil, which consists of a single sealed line. This coil is usually located near the top or bottom of the unit, so water flows over them when you turn on the AC. Without forgetting whether it is dirty coils or not


4- Check The Frozen Evaporator Coil

The condition of the evaporator coil is frozen or not, depending on whether the refrigerant has leaked out. If there is a system leak, it will be frozen. If not, then it will be warm to touch.

When you turn on your air conditioner, and it does not work, you need to check if there is any refrigerant leak by using a test light or an electric meter. You may have to reset the circuit breaker if this causes problems.

If there is no refrigerant leak and your unit still does not perform properly, you should open up your unit and check for leaks with a pressure gauge and visual inspection of all components.

6- Get An Airflow Check

You’ll want to check airflow when the AC is not cooling your home. If there is proper airflow, it could mean a few things. It could be that there is no air going into the vents. Or, it could mean there is no air going through the AC. It means poor airflow. To check airflow, you can use a thermometer and a paper towel. 

The thermometer can check the temperature inside and outside your vents. If hot air outside the vents than inside, there’s no air flow. If there’s no airflow, you can check if there’s air going into the vents by putting the paper towel in the duct and seeing if it comes out the other side.

Refrigerant Line

7- Check The Refrigerant Line

The refrigerant line brings the refrigerant from outside the AC to the inside. If there’s a kink or dent in the line, it can cause the ac freeze. You can check the line for kinks or dents to ensure it’s not causing a problem. If it does have a lock or pattern in it, you can replace it. This can help prevent the AC from freezing up. You can buy a new refrigerant line at a home improvement store and replace the old one. This can help the AC run properly again. 

* Make sure there are no refrigerant leaks in the air conditioner unit.

Make sure there are no refrigerant leaks in the air conditioner unit. Refrigerant leaks can cause the system to over heat, which can damage your air conditioner and result in a fire hazard. Contact a licensed technician immediately if you have any suspicions of a leak. If you believe a leak has damaged your unit, contact a professional for assistance. 

* Check refrigerant leaks

Check it by running a fan and watching for light from behind the compressor. If not working, then you leak! Seek professional help immediately as this damage is dangerous and may require immediate repair or replacement.

8- Check The Warm Blowing Air With High Heat

Your air conditioner’s thermostat may be malfunctioning if it’s blowing warm air. You can check the thermostat of heat first to ensure it’s not the thermostat. 

If the thermostat isn’t the issue, low refrigerant levels are. The refrigerant affects the pressure in the AC and helps it cool your home. If there’s too much refrigerant in the AC, it can cause the AC to blow warm air. You can take the AC to a repair shop to have them check the refrigerant levels.
