The compressor’s failure can make your home warm and humid. You need to be aware of the early signs before this vital piece of equipment fails completely. The compressor is the heart of the cooling unit. There are several indications that there is a severe problem with this component. Here you will learn about the most common signs of compressor failure.
People often neglect AC maintenance until there is an issue with one of the vital components. The compressor usually sends several indications when it reaches its limits. Strange noises, low airflow, and hot air coming out of the vent are some of the early signs. Other signs include a strange smell and frequent tripping of the breaker.
Unusual Noises From the Outdoor Unit
If a system works fine, it should produce a steady and low humming sound. However, grinding, screeching, and clanking indicate that bearings and inner components are worn or loose. Such sounds usually become louder and more noticeable over time. The rattling noise is likely caused by the loosened mounting bolts. Squealing usually means that there is a problem with the motor or belt. All unusual noises from the outdoor system need to be checked by an expert immediately.
Warm Air Through the Vents
The compressor is the component that moves refrigerant responsible for heat removal. In case of compressor failure, warm or room-temperature air can come through the vents. This issue can also be caused by a lack of refrigerant or clogged filters. The technician needs to conduct a diagnostic of the compressor in order to eliminate other causes of the problem. Usually, the best thing to do in case of compressor failure is to replace it.
Compressor Breaker Tripping Repeatedly
A compressor using more electricity than usual will cause the breaker to trip repeatedly. This is because the internal components have worn out and increased the electrical load on the system. However, a repeated trip indicates there is an issue within the system. A homeowner should never reset the breaker because it can lead to damage to the entire system, as well as safety issues. A technician can test the amperage draw.
Increased Utility Costs and Short Cycles
When a compressor has less efficiency, it uses more energy in doing its job. As a result, utility costs increase each month. In addition, the unit turns on and off very quickly, causing short cycles. During a service appointment, a technician can test the compressor and other components of the system. Increased utility costs without any reason indicate a problem with the compressor.
Leakage of Refrigerant or Oil
The compressor will leak refrigerant or oil with old seals. The dark oil spots in the area around the outdoor unit could indicate such a situation. The low amount of the substance means inefficient work and additional stress for the unit. A professional will locate the source of the leakage and diagnose the state of the compressor. Most of the time, the only solution will be its replacement. Thus, prompt action will help avoid more serious consequences for the entire system.
Unit’s Age and Repairs
The lifetime of most compressors ranges from ten to fifteen years. The outdated system with multiple problems might not be worth repairing once again. A professional will compare the price of a replacement with that of the whole system. Usually, in such situations, it is better to invest in the new installation. People should keep all the information about every repair done to the system.
Warning Signs of a Need for Replacement Compressor
There are certain signs that can indicate the necessity to replace a compressor soon. People have to be aware of these warning signs of a need for a compressor replacement.
- Grinding and screeching sounds usually indicate worn-out internal parts of the compressor.
- Warm air coming out of the vents indicates a failure of the compressor’s cooling function.
- Frequent breaker trips indicate an overload caused by a malfunctioning component.
- Oil stains in a dark color close to the outdoor unit indicate a leakage of refrigerant.
- Growing expenses on the electricity bill and short operation periods indicate high loads on the compressor.
Professional Help Is Needed
Some people might try to determine the issue themselves. However, this approach is dangerous since the compressor contains high voltage and pressurized refrigerants. An experienced technician has special equipment and skills to perform the work. An inspection includes electrical and pressure measurements as well as inspection of all moving parts. After the work, a technician will inform the person about the next actions.
There are definite symptoms of a faulty compressor, including loud noises, warm air blowing out from the vents, and hefty electric bills. Taking timely steps will help to save the equipment from breaking down completely in the summer heat of the year. The best thing for homeowners to do is have a professional inspect their air conditioner as soon as possible after noticing any symptoms. One useful piece of advice is to have the AC maintained twice a year.
