G UP? HOW TO FIX IT?

 

It happens all over America. And the rest of the world probably. It’s the hottest day ever and for some darn reason your AC isn’t cooling the house. You fiddle with the thermostat to try and fix the problem. Nada. All you can do now is go outside and check the AC unit. You make your way there and find your air conditioner unit is frozen! But how?


In this post we’ll cover how you can tell that your air conditioner has frozen (other than the obvious reasons), what could have caused the freeze, and some of the things you can do about your AC freezing up. And if you have a frozen heat pump condenser, read our blog about it to learn what to do! But remember, it is always best to avoid your AC freezing up with an AC tune up. And if you are moving into a home, it's critical to get HVAC inspection so that you are aware of an AC problems before you move in.


Keep reading and you may be able to fix the frozen AC yourself. If you can’t, call an HVAC specialist. If you live in Maryland, call SuperTech HVAC for AC repair. We’ll take care of it.

 

How Does An Air Conditioning Unit Work?

 

How you probably imagine an AC works is wrong. Contrary to popular belief, an AC system does not inject cool air into a building. Instead, it removes the heat from inside and transfers it outside. Cool huh? (Pun intended).There are 4 major components among the 3 stations of an air conditioning system: the evaporator coil, the compressor, the condenser, and the refrigerant – a special chemical that links everything together through a closed loop system.

 

 


Station 1:

 

Warm indoor air is sucked into the return vent, through a filter, and blows over the evaporator coil. The heat is absorbed into the cold refrigerant, turning it from liquid to gas. The air, which is now cool, is blown back into the home to areas that your thermostat, i.e. you, has decided.

 

Station 2:

 

The refrigerant makes its way outside the house to the compressor, which squeezes the warm refrigerant, raising its gaseous temperature even more.

 

Station 3:

 

When the super hot vapor refrigerant reaches the condenser, the last step, the heat is expelled and absorbed into the outdoor air. The refrigerant instantly cools, which changes it from gas back to liquid form. The cold liquid refrigerant is now ready to return to station 1 and repeat the process.

 

Is Your AC Freezing Up? Here Are The Signs:

 

As you may have guessed, your air conditioner unit freezing up on a hot day is not normal.


If this happens, there's no need to panic. Often the issue can be solved with a little troubleshooting. If the AC unit is left frozen for too long however, you may find yourself with a bigger problem.


First things first, how do you know your AC is frozen?


Well, the obvious sign is the ice on your refrigerant line-set pipe. Simply check between your outdoor AC unit and your home's exterior wall to see whether your AC line frozen.


You might also have a frozen evaporator coil. This one's not as easy to check. You'll need to open a panel on the indoor unit to inspect. Don't do this unless you're handy. If you aren't, call an HVAC pro like SuperTech HVAC or you may damage something in the process.

5 Reasons Why Your AC Line is Freezing Up and How to Troubleshoot Them

 

There are multiple reasons why your AC line is frozen. Anything from dirty filters to refrigerant leaks can cause a frozen AC line. Not all reasons can be easily fixed at home, and you may need an air conditioning repair service to tackle chemical coolant leaks, and the malfunctioning of internal parts.


Blocked Vents

 

First, check the supply vents. Are there obstructions blocking the supply vents, causing the cooled air to circulate inside the unit, or are there obstructions making it difficult for the cold air to travel through the room? Obstructions, such as furniture, fixtures, and walls, blocking the air flow from the vents are some of the common reasons why your AC line is frozen.


To troubleshoot, power your AC system off. Check all the vents in both the indoor and outdoor units to see if there are fixtures or debris blocking the supply vents, and remove these obstructions. Let the frozen AC line thaw out before powering the AC system back on, then see if this solves the problem with your air conditioner line.



 

Dirty Air Filter and Coils

 

You may notice your AC unit blowing warm air instead of cool air due to a dirty air filter. Besides blocked vents, dust accumulated in filters and coils can also cause a frozen AC line as the debris locks in moisture inside your air conditioning system. As the air conditioner cools the air, it freezes the accumulated moisture surrounding the filter and evaporator coils.


Troubleshooting this problem is fairly simple. Power your AC unit off, then let the frozen AC line thaw. You may use a hair dryer to apply warm air to thaw the ice buildup faster, but this is not necessary. Remove the air filter carefully, and wash it with a combination of soap and water. Vacuum up the dust surrounding the evaporator coils.

 

Refrigerant Leak

 

A refrigerant leak is another cause for a frozen air conditioner, however, this issue cannot be easily solved at home. Refrigerant is what cools the air that goes through the air conditioning unit, and when the chemical coolant leaks out, it can freeze up the water accumulation around the evaporator coils.


Refrigerant leaks cannot be solved at home without proper tools. The coolant can be irritating to the skin and lungs, so it is best to have a professional find and fix the leak. A professional HVAC technician will use a colored dye to locate the leak, fix it, and top up your refrigerant to keep your air conditioner in good condition.

 

Cold Air

 

If the weather is cold outside, it can cause your air conditioner to freeze. An air conditioner freezes when there is enough humidity inside the unit, coupled by freezing-low temperatures outside. When this happens, your AC unit may blow warm air instead of cooled air, and you may notice ice accumulation around the evaporator coil.


To troubleshoot this, shut down your air conditioner, and check the frozen AC lines. Air conditioners often dehumidify spaces, so check whether a dirty evaporator coil is causing moisture to accumulate inside. Let the frozen AC lines thaw out, and clean the filters and dirty evaporator coil as needed. Avoid using your unit in cold weather.

 

Blower Fan Failure

 

You may notice the air flow around your unit getting weaker despite using the highest fan mode setting. This may be due to a problem with your blower fan. A malfunctioning blower fan cannot direct the cooled air out of the unit, while the exhaust unit continues to remove warm air from inside the air conditioner. As a result, the unit’s evaporator coil freezes.


For blower motor and fan blade problems, it is best to leave the issue to the professionals as they will be able to assess and determine the root cause of the problem. Have your faulty fan motor replaced, and have a professional check your air conditioner from the compressor to the evaporator coil for a thorough checkup.

 

Clean your air conditioner thoroughly

 

Wash the air filter at least once every two weeks to remove dust accumulation, and vacuum up the evaporator coils as well. Give your outdoor unit a good rinse with the garden hose on a hot day to dislodge any debris inside.

 

Avoid using your AC unit in cold weather

 

Cool temperatures can cause moisture inside your AC unit to freeze, so it is best to use the heater setting of your unit, or keep the temperature on a moderately high level to prevent a frozen AC line.

 

Have your unit professionally checked

 

Your HVAC system will benefit from a professional checkup by one of our Luce Aircon technicians. Have our technicians check your unit every 4-6 months for the best care.

 

Avoid overworking your AC unit

 

An overworked air conditioning system is more likely to break down faster. Use your HVAC systems only as needed, and let the air conditioning unit cool down after a long period of use.

 

Keep the vents clear

 

This will keep the air flow circulated around the room, and prevent the cooled air from freezing up your AC line.
