Problems from Too Much Refrigerant in an Air Conditioner

One of the common problems that air conditioners may encounter into is loss of charge, i.e. a drop in the level of refrigerant that is vital for an AC to operate. When charge is low, an air conditioner will begin to lose cooling performance and ice will develop along the evaporator coils. (Although it seems strange to people that loss of refrigerant would cause coils to freeze, this happens because the refrigerant in the coils can no longer absorb sufficient heat to warm up, and so remains too cold.)

There is an opposite version of this problem: an AC that has too much refrigerant. An overcharged air conditioner is usually the result of an amateur worker tampering with the system and putting in more refrigerant than the AC should have; it is a very easy mistake to make—and unfortunately one with serious consequences. This is one of the reasons you must always rely on professionals for your air conditioning repair in Rancho Cucamonga, CA. The experts at Avis Plumbing, Heating and Air are here to assist you, whatever problems you may experience with your cooling system.

The trouble with overcharged refrigerant

The main danger with too much refrigerant inside an air conditioner is that it can damage to the compressor. The excess refrigerant will collect inside the compressor and lead to subcooling, temperatures below normal. The extra refrigerant can also flood the compressor and damage its mechanical components. (This is called slugging.) Fixing damage to the compressor is one of the most expensive air conditioner repair jobs, and may require the whole system be replaced.

An overcharged air conditioner will also create higher pressure inside the system. This first effect this will have is to make the system more expensive to run, since it will not cool as effectively. If you noticed a drop in cooling combined with elevated AC bills, call an air conditioner professional right away. The symptoms of overcharging are similar to other common air conditioner repair problems, and it takes experts to determine the exact cause of a malfunction. If excess refrigerant is the source of the problem, the technician will drain the extra amount to restore the system to its regular charge, and then take care of any damage the overcharge may have caused.

Keep in mind, an overcharge of refrigerant will likely lead to wrecking the compressor, and this is something you want to avoid at all costs. If your AC isn’t running the way it should, call Avis Plumbing, Heating and Air for professional air conditioning repair in Rancho Cucamonga, CA.
