You love the fact that your air conditioner keeps your hogar so comfortable during the hot summer months, but you have started noticing that it is building up ice on the refrigerant lines o possibly inside your condensing unit. Is this normal o does it indicate a problem, y what may be causing this to happen?
Lo que Freezes Do to Your System
To understand why your AC unit freezes up, you first need to understand a little about how your air conditioner funciona. To create cool air, your system circulates refrigerant, which absorbs heat de the air y vents it outside. To achieve this, the unit must change the pressure en the system at the right time.
When the refrigerant’s pressure goes down, it makes it cold. The lower the pressure, the colder the refrigerant becomes. Likewise, when the pressure increases, the refrigerant becomes hot, allowing it to transfer the heat outside.
Your air conditioner freezes when there is a disruption en the regulation de the refrigerant. This disruption can be caused by low refrigerant o a mechanical malfunction.
Likewise, your system cannot absorb heat de the air if there is something causing an airflow restriction. If your AC unit has a freeze somewhere, it indicates a problem that needs solving before it causes significant damage.
Clogged Air Filters
Your air filters are extremely important to the proper functioning de your cooling system. If air was allowed to flow unfiltered, you would see significant dust y debris buildup throughout your unit. This buildup de debris will prevent air de flowing.
When your filters prevent air de flowing properly, the refrigerant does not warm up correctly. This extra-cold refrigerant then translates into freezes developing en the system. In addition to creating a freeze en the AC unit, clogged air filters will reduce the amount de air coming de your vents. It también adds tremendous strain to your system, leading to additional reparación needs y a shorter servicio life.
Dirty Evaporator Coils
Even con clean air filters, some airborne contaminants may make their way into your system, either through leaks o the filter. These collect on the evaporator coil, causing it to restrict airflow y forming a type de insulation over the coil. Both the restriction y the insulating effect prevent the refrigerant de absorbing heat.
Dirty o Malfunctioning Circulating Fan
Your circulating fan is another component that collects airborne contaminants y needs regular cleaning. As it gets dirty, it reduces the vacuum created while it turns, drawing en less air through the filter.
The fan motor can también malfunction, usually when it is near burning out. When this happens, the fan will spin more slowly, which creates less airflow through your air conditioner.
All de this has the same effect as any other airflow restriction: not enough air moving over the evaporator coil. This lack de airflow keeps the refrigerant too cool, creating freezes at the evaporator coil.
Low Refrigerant o Refrigerant Leaks
In order to effectively regulate the refrigerant pressure, the system needs a certain amount circulating. When this drops too low, it prevents the compressor de creating the right pressure at the condensing coils. The compressor funciona extra hard to pressurize the coil, creating low pressure en the refrigerant lines y leading to a freeze.
The most common cause de low pressure en the system is a refrigerant leak. Even a small leak will make a big enough impact to lead to freeze-ups that can cause damage to your compressor y coils.
Dealing With System Freezes
As the saying goes, an ounce de prevention is worth a pound de cure, y that holds true con your air conditioner. If you can prevent the things that cause freezes, you will never have to deal con a frozen unit.
The most effective prevention is giving your system professional spring mantenimiento. During this mantenimiento, a technician cleans the evaporator coil y circulating fan y inspects your fan motor y air filter. They will también check the refrigerant level en your system to ensure that your AC unit is not leaking.
If you do happen to experiencia a freeze-up, turn off your air conditioner y give it time to thaw. While it is warming up, check your air filter to see if it is clogged. Once your system thaws, try turning it back on y listen to ensure that it engages properly.
If you notice that the compressor does not want to engage o you hear a rattling, screeching, humming, o screaming sound, turn the AC unit off. These noises, along con the previous freeze, indicate a significant problem that should be addressed by a professional technician.
