AC Compressor in Sacramento, CA

A compressor is the heart of your air conditioning unit and an expensive component in the cooling cycle. Your AC unit’s compressor keeps your living space comfortable and cool during the hot summer by transforming power into energy. The role of this device is to circulate refrigerant through your air conditioning unit. Compressors can last between 10 and 15 years with proper care and maintenance. However, failure to service your air conditioner can lead to increased wear and tear.

Debris, dust particles, or refrigerant leaks significantly impact the performance of your cooling unit’s compressor. You have an AC emergency when an AC compressor breaks down or stops working. In some scenarios, you cannot fix it, and AC replacement is the only possibility. Here are the common AC issues associated with air conditioner compressors and how to prevent them.

1. Improperly Sized Suction Lines

An improperly sized suction line can cause compressor failure. Too short or long suction lines can build pressure and even overheat the device. If you want to install or repair a suction line, you need to engage an AC professional. These experts know the type of suction lines suitable for different air conditioning units, and they’ll install the correct length of suction lines.

2. Damaged or Blocked Suction Lines

With time, your cooling system’s refrigerant lines can develop holes and cracks. These openings may hinder refrigerant flow and put unnecessary pressure on your unit to work harder. One of the major indications of this problem is the decline in your system’s cooling capacity. Reduced cooling forces your air conditioner to run for longer durations, increasing its power consumption and wear and tear on its components. It also reduces the efficient performance of your unit. If your air conditioner is not achieving your desired temperature, you should call your AC expert to inspect your unit.

3. Overheating

One of the common causes of compressor failure is overheating. And there are many things at play. For instance, your AC compressor will overheat if you expose your outdoor unit to direct sunlight when there’s insufficient ventilation around it. High power voltage can also damage the unit’s motor, causing your air conditioner’s compressor to overheat. Low refrigerant levels, lack of insulation, and dirty coils can cause the compressor to overheat, leading to failure.

4. Electrical Problems

Electrical problems can cause irreversible damage to your air conditioner’s compressor and other parts of the system. Damaged fuses and wires can cause electrical failure. When electrical errors occur, acids that are detrimental to your unit can build up in the AC unit, causing other parts of the system to malfunction, too. Power surges may also lead to electrical problems within your air conditioning unit.

One of the most common signs of electrical problems in air conditioners is oxidation and acid buildup. Scheduling routine AC tune-ups can help prevent electrical issues. An experienced HVAC technician can inspect your AC for acid buildup and repair damaged wiring, fuses, and other components before they destroy your compressor.

5. Low Refrigerant Levels

Your air conditioning unit cannot cool your living space without the right amount of refrigerant. There’s a common misconception that refrigerant levels drop with time. But air conditioners do not use up refrigerant during operation. If the level of refrigerant in your AC is low, you need to contact your technician to check your unit. Sometimes your unit’s refrigerant lines may develop holes or get cracked. As a result, the refrigerant flowing via the lines may leak, decreasing your unit’s refrigerant charge.

If your air conditioner’s efficiency to cool your residence drops and you realize the system is not cooling your residence as per your needs, you might be dealing with a refrigerant leak. Low refrigerant levels normally decrease pressure in the unit, forcing the compressor to work hard to push refrigerant in your AC system. If you don’t address this problem immediately, it’ll cause your AC system to overheat, and your compressor will eventually fail.

6. Too Much Refrigerant

Like improperly sized suction lines, the wrong refrigerant type or too much refrigerant can damage your compressor. One of the common mistakes often overlooked by homeowners or unqualified contractors is filling the cooling unit with excessive refrigerant. A less qualified individual may not know how to fill an AC properly and end up putting in more than the needed amount.

The refrigerant levels should match the quantity indicated by the AC unit’s manufacturer. High refrigerant levels increase pressure within the system, resulting in premature compressor failure. You can avoid this problem by calling experienced HVAC experts to handle your air conditioner repairs and tune-ups.

7. Lack of Enough Lubrication

Your air conditioning unit needs the right amount of lubrication to run optimally. Inadequate lubrication can increase wear and tear in your AC, forcing the compressor to work harder. Low oil levels will cause the compressor parts to rub against each other. As a result, some parts will become loose while others will detach from other unit components. Lubricant levels work like refrigerants. Lack of enough or excess oil can cause your AC unit to function incorrectly, resulting in compressor damage or failure.

Loss of lubrication in air conditioning units is mostly due to leaks from the condenser, compressor shaft seal, pipe connections, or evaporator. An overstressed AC compressor is more likely to break down before its expected lifespan. You can avoid this problem by having your cooling unit maintained by an HVAC contractor at least once a year. At Gallagher's Plumbing, Heating and Air Conditioning, our technicians will check the system’s oil pump condition and lubricant levels to prevent compressor damage and other problems associated with low lubricant levels.

8. Dirty Coils

Some parts of your cooling unit accumulate dust, dirt, pollen, pet dander, and other debris with time. If the condenser coil accumulates debris, the buildup can hinder hot air expulsion, forcing the air conditioner to work harder to attain your desired temperature. The huge amounts of heat trapped in your AC causes your system to overwork, leading to compressor overheating. One of the ways to know your AC condenser coils are dirty is the unit running nonstop. If your cooling unit is running continuously, call your air conditioning service to identify and fix the problem. Ignoring this problem can result in the premature breakdown of your AC compressor.

9. Displacement of the Evaporator Motor

A displaced AC evaporator motor can force refrigerant to return to the unit’s compressor. In turn, the refrigerant will displace the compressor oil, and your air conditioner may eventually experience lubrication problems. Displacement of the evaporator motor can also cause the AC’s compressor to lose efficiency and eventually break down.
