10 Reasons Your Air Conditioner Compressor Fails
AC compressor failure is usually due to an internal problem that impacts the performance of your compressor over time.
Here is the list of 10 common causes of air conditioner’s compressor failure that require your immediate attention:
Wondering how the excess amount of refrigerant got in your unit? Have you ever had an issue of low refrigerant level and called a technician to fix it?
A less qualified person may not know how to fill it up properly and end up filling it more than what is needed. The refrigerant levels must match exactly with the quantity specified by the manufacturer. High levels of refrigerant can lead to increased pressure in the system, causing premature AC compressor failure.
It’s always recommended to call an experienced HVAC expert to deal with air conditioner issues.
7. Lack of Lubrication
Your HVAC needs the correct amount of lubrication to function optimally. Without adequate lubrication, the wear and tear will increase, making your compressor work harder. When there are low levels of oil, your compressor parts rub against each other. This makes small parts come apart and are let loose in the system.
Loss of lubrication is mostly due to leakage from the evaporator, condenser, pipe connections, or the compressor shaft seal. An overstressed compressor is likely to break down earlier than its expected lifespan.
Getting your air conditioner serviced is the key to prevent this problem. The experts will check the lubricant levels, make any necessary adjustments and see if the oil pump is working fine.
8. Clogged or Damaged Suction Lines
Over time, the suction lines of your refrigerator can develop cracks and holes, hindering the refrigerant flow in the system. This puts stress on your compressor as now it has to use extra power to pump enough refrigerant through the unit resulting in a breakdown. One of the evident signs is a decrease in the cooling capacity.
If you notice your unit is not cooling like it’s supposed to, call an HVAC expert to have a look at the suction lines.
9. Dirt & Debris Stuck in the Outdoor Unit
Outdoor pollutants, dust, debris, soot, and moisture can enter your outdoor unit and cause issues for your compressor.
Moreover, air can also be introduced, and it can dispel refrigerant in the condenser. This can increase the temperature inside the compressor and can cause oil carbonization on the discharge valve. Oil carbonization results in residue buildup and makes the valves leak. Leaking valves further increase the temperature, causing more damage to the compressor.
You can avoid this problem by scheduling annual AC tune-ups.
10. Incorrect Sizing of Suction Lines
If your suction line is too long or too short, it can cause AC compressor failure. Wrong sizing can build pressure and overheat the compressor.
This issue mostly arises when an untrained or amateur technician attempts to repair the line and installs the wrong size. It is always best to call a professional for any AC repairs. They know what type of suction line is best suitable, and they will install the right length of the suction line.
