What are the causes of air conditioner explosion?

What are the causes of air conditioner explosions? This is a recurring question in the changing summer season, with rising temperatures accompanied by homeowners and companies ignoring the problem of regular maintenance of air conditioning devices. Ways to prevent air conditioner explosions, in addition to considering the most important malfunctions that can happen to the air conditioner.

What are the causes of air conditioner explosion?

Most air conditioner explosions result from a malfunction of the compressor, the external part of the air conditioner. According to American company Arister Heating and Cooling, regular care and constant inspection of the compressor can protect against catastrophic explosions that may be the result of a compressor malfunction. The American company detailed the causes of air conditioner explosions in several points, namely: 

The air conditioner coil is dirty

Negligence in cleaning and maintaining the air conditioner leads to the accumulation of dirt and dust on the condenser coil in the compressor, which may lead to the air conditioner being unable to cool and thus the room temperature rises at the same time as the air conditioner temperature rises. The compressor system works continuously without any benefit in cooling the place, and the high pressure and high temperature lead to the compressor temperature rising insanely and it explodes after a while.

Clogged cooling lines

Clogged air conditioning refrigerant lines due to dirt or damage leads to increased pressure and overheating, so the compressor does not cool and explodes.

Low refrigerant charge

Holes or cracks that appear in the refrigerant lines within the system cause a large portion of the gas intended to operate the compressor and produce a cold stream to leak into the site. This doubles the work of the compressor to pump larger quantities of refrigerant gas to ensure continuity of work with high efficiency to occupy space, thus producing excess pressure.

Failure to comply with cooling lines

The cooling lines are connected to each other using high-precision actuators and connectors. A simple leak in refrigerant lines, large or small, can lead to catastrophic compressor failure.

Electrical problems

Electrical problems are classified as one of the biggest causes of air conditioner explosions, because power outage, connection, and instability can lead to the accumulation of acids in the cooling pipes, causing major damage to all parts of the air conditioner, the most important of which is the compressor. If the matter is not discovered early, it can lead to The air conditioner explodes and causes a disaster.

Technicians and electrical experts in the field of air conditioner repair believe that the acid causes a complete failure of the compressor, in addition to the inability to repair it.

Waste in the system

Waste includes dirty air, moisture, dirt, debris, leaves, acids, and even bird droppings and small insects, which can cause blockages in refrigerant pipes and lines, high pressures that accompany high temperatures, and compressor stoppages.

Lack of air conditioning oil

It is considered one of the main causes of air conditioner explosion, because the oil used in the air conditioner is considered blood in the human body, so a lack of its quantities in the air conditioner leads to the system malfunctioning. Failure to work fully, final malfunction, compressor failure, and air conditioner explosion.

Using the wrong gas

Air conditioners are manufactured according to a specific type of gas that serves them at the time of installation and operation. Using the wrong gas in your air conditioner could cause it to overheat and cause it to explode. Freon is the most common refrigerant gas in air conditioners and is non-flammable. It is classified as a major contributor to global warming and its production has declined. Using it, R410a gas, called boron, was released, which is also a non-flammable gas.

Signs of air conditioner explosion

Users can predict the impending climate explosion by observing the following signs:

  • The compressor continues to work without stopping. This is the condition that occurs when a window is opened in the room or the air conditioner is unable to cool large rooms that exceed its cooling capacity.
  • A squeaking or crackling sound from the compressor and air conditioner indicates the presence of one of the defects mentioned in the previous paragraph.

Ways to prevent air conditioner explosions

Climate and air conditioning systems experts have identified several steps to avoid catastrophic air conditioner explosions, which are as follows:

  • Keep the air filters in your air conditioner clean of dust and dirt.
  • Make sure to tilt the indoor climate unit slightly out of the room to ensure that condensation drains quickly.
  • Do not use electrical extension cords in the air conditioner because they are unable to bear the high electrical load of the air conditioner.
  • Turn the air conditioner off and on during natural storms.
  • Check topics periodically to ensure their safety.
  • Providing the air conditioner circuits with protection resistors to prevent excessive voltage from the air conditioner exploding.
  • Connect the air conditioning circuit separately to ensure the protection of electrical appliances operating in the same cooling room.
  • Make sure to use the correct gas when filling gas into the compressor.

Causes of air conditioner leaks

Experts attributed the causes of the air conditioner to fall to one of the following cases:

  • Air is leaking from the vent.
  • The air filter broke and the air froze on it and leaked through the air bell.
  • Dirty air filter.
  • Defective condensate pump.
  • Dirt accumulation in the external compressor of the air conditioner.
  • Drain line blocked.
  • Poor installation may cause water to leak from the air conditioner.
  • Rust is accumulating on the drain pan.
  • The evaporator coil is frozen.

In conclusion, we have answered the question: What causes the air conditioner to explode? We have listed the signs of an air conditioner explosion and ways to prevent an air conditioner explosion, in addition to explaining the reasons for the air conditioner to fall.
