Even in Florida’s scorching summers, it’s not uncommon for your air conditioning line to freeze. HVAC issues can arise for any variety of reasons, but the most prevalent causes of an AC line that has frozen include the following: An HVAC specialist is the best person to diagnose your air conditioning system, and we’ll provide a few simple repairs in this post. Having a frozen AC line is a sign of a more serious issue. The longer it goes unattended, the more expensive it will be to fix the HVAC system. If your AC line is frozen right now and you need a quick fix, switch your thermostat to FAN mode and turn your AC off immediately. You can then return to this page to learn about the initial measures you can take to explore why your AC system is freezing. Let’s take a closer look at the problem now that the AC is off and the fan is operating.

What Causes Your Air Unit To Be Frozen

Evaporator coils overheating is the most common cause of frozen AC hoses. The refrigerant in your HVAC system cools the air passing through the evaporator coil. A well functioning evaporator removes heat from the air and dissipates it as cool air. In the event of a malfunction with your air conditioning system, the heat exchange mechanism may be hampered, resulting in less heat absorption by your evaporator coils and the formation of ice on the coils. The refrigerant pipe may become clogged with ice over time.

Some Common Reasons That Cause Your AC Lines To Freeze Are:

  • The evaporator coils are leaking refrigerant.
  • The coils become clogged with debris.
  • Blocked air conditioning vents
  • Dirty air filters
  • Failure of the blower fan.
  • Collapsed conduits
  • Low levels of refrigerant

Simple And Quick Ways To Eliminate AC Freezing

Do some troubleshooting on your own if your refrigerant lines are completely iced over. Here are a few things you can do if your air conditioner isn’t working. If the problem persists despite your efforts, you’ll need to get in touch with a professional HVAC provider for assistance in determining the root reason.

1. Turn Off Your Air Conditioner and Switch To Fan Mode

As heated air from your house circulates through the system, it will allow your air conditioner time to cool down. After 3-4 hours, you can restart your computer. You should contact Pro-Tech for air conditioning repair if your air conditioner freezes upon restarting.

2. Check For A Dirty Air Filter

Air conditioner freezing is a serious problem that can be caused by clogged air filters. If you find that your filter is clogged, replace it. Having a clogged filter could be the core cause of the issue.

3. Check out for any blocked or closed return/supply vent

The supply vents in your home are responsible for distributing cold air throughout the residence. It’s possible for your air conditioner’s heat exchange process to be hindered by a closed supply vent. To defrost the frozen coils, it’s better to leave all the vents open, even in rooms that aren’t being utilized. Increasing the flow of warm air over the evaporator coils can be accomplished by doing the same thing with the return vents.

Kinds Of Pipes In An Air Conditioner

There are many different sorts of pipes in an air conditioner, but first let’s talk about what they are for. We can now see why these pipes freeze up in this manner. Let’s find out what our air conditioner, our friend, is hiding. In the first place, the pipes that must be utilized in the air conditioning system cannot be susceptible to temperature variations. Metal is the best choice for this job because of this circumstance. It is true that the air conditioner employs metal piping in its internal components.

Pipework is critical in the cooling process since it is a closed system. It is possible that these pipes will leak or crack, resulting in less efficient cooling. Aluminum and copper are the two metals most commonly used in air conditioners today. For the sake of clarity, let’s take a closer look at their distinctions and which metals are the most suitable.

Type #1. Copper pipes

When it comes to air conditioning systems, copper pipe is the preferred metal pipe. This metal pipe is superior to the aluminum pipe in terms of performance. These features, however, have the unintended consequence of backfiring.

In compared to aluminum, copper pipe is more durable, cools faster, and has greater anti-corrosion performance. Because of its unique properties, copper pipe is a pricy material to work with. When it comes to choosing an air conditioner, you have two options: high quality or pragmatism.

Type #2. Aluminum pipe

Copper pipe outperforms aluminum pipe in terms of strength and flexibility. However, it’s known for its low pricing. This type of metal pipe is ideal if you don’t care about aesthetics and would rather save money over time. There are advantages and disadvantages to this type of metal pipe, but that doesn’t mean it can’t accomplish its job. There are certain advantages to using galvanized steel instead of copper metal pipes. As a result, even though they are more expensive, copper-piped air conditioners are more popular than aluminum-piped ones.

Serious Problems That Need Additional Investigation

Call a professional air conditioning provider if the DIY options don’t work for you. Without the assistance of an expert, there are likely to be more issues.

Refrigerant Leak

If the pressure in your AC system drops, there may be a refrigerant leak. The liquid refrigerant is responsible for removing heat from your home and dispersing it outside via a compressor. Ice builds up in your refrigerant lines when the pressure inside them becomes out of whack due to low refrigerant levels. The following are signs that your air conditioner has a refrigerant leak:

  • Vents are spouting out hot air.
  • You hear a bubbling or hissing sound coming from your device
  • Due to a greater demand on the air conditioner, power costs will rise.

Blower Motor Not Working Properly

A malfunctioning blower motor prevents the fan from pulling in enough warm air within the unit, which leads to ice buildup in the system’s lines. If you see any of these symptoms, there may be an issue with the engine.

  • Slower than normal, the blower fan rotates.
  • Having difficulty getting started
  • The act of emitting a humming noise.
  • There is no warm air being blown outside at the moment.

Torn Or Collapsed Air Duct

The passage of warm air to your evaporator coil is disrupted when the air duct collapses. As a result of the drop in temperature, the refrigerant lines in your air conditioner freeze. Any of the factors listed above could cause your air conditioner to freeze and necessitate professional repair. Make sure that ice does not build up on the refrigerant coils of your system at any time. If the problem persists despite your efforts, seek professional assistance.
