Although most air conditioners become defective due to various reasons, faulty compressors are the main ones. Poorly maintained air conditioners develop compressor issues, which only a professional technician can handle. Any professional technician will know your AC unit has a defective compressor by observing certain symptoms.
Decreased cooling capacity
Allairservices.com.au shares air conditioners reduce their cooling capacity when there’s improper refrigerant charge. This problem could also show up if the compressor has pressure-related issues. If the discharge pressure is very low or the suction pressure is significantly high, the compressor of your AC unit will not be able to regulate pressure. This means cooling your home will not be easily achieved.
AC turns off and on repeatedly
The compressor uses high amounts of energy once it’s turned on. Air conditioners that cycle off and on constantly have limited ability to maintain or achieve comfortable temperatures. This problem also denies the AC unit the ability to eliminate humidity in the air. Most experienced HVAC technicians assert that blown fuses and electrical problems such as frayed wires cause the ‘hard starting’ problem.
Most electrical problems occur due to improper installation. AFB.org says you should hear a pop if there’s a loose wire.
Compressor consistently fails or won’t start
Air conditioners with this problem have defective motors. The problem occurs because the insulation that keeps the windings protected is worn. In some instances, fuses trip to prevent the AC units from working whenever a motor is burnt out. If the compressor is locked up, it becomes hard for it to start, and replacing it is a costly affair. To most people, even finding the right compressor for their air conditioning unit is a big problem despite having the money.
The AC compressor is one of the most expensive parts of any AC, and it requires good maintenance. Check the condition of your compressor if you notice any of the symptoms mentioned.
