Does air compressors devalue?

An air compressor is a crucial tool for any weekend warrior, DIY enthusiast, or professional who works with tools. It stores air under pressure which serves as an energy source to multiple air tools such as brad nailers, impacts wrenches, inflators, fasteners, hammers, framing nailers, etc. So, as you can see, air compressors are found everywhere, from homes, garages, and offices. The question most people ask is that, does air compressors devalue?

Devaluation infers reduction in worth, and air compressors fall under machinery. Yet, pieces of machinery have a depreciation rate of 15%. However, there is no definite lifespan for an air compressor tank. As long as it is for personal use and you keep servicing it, an air compressor can serve you for a lifetime.  We are going to talk about the maintenance of an air compressor later. The simple things you should do are avoiding surface dents and ensuring you drain your tank regularly after use.

How to identify red flags in your air compressor

In an ideal world, you will operate your air compressor at peak performance throughout its lifespan. However, that’s not the case, but you can archive near optimum circumstance by skilled service. So, how will you know that your air compressor is nearing the end of its life? Here are the signs:

External signs of wear-This are observed in normal working daylight as it shows broken reflector lights or rusted body.

Excessive Noise-If you notice that the air compressor is operating at a higher vibration or sound than the regular operation, there is a high possibility of technical faults.

Worn or rusted rings, seals, piping, and bearings- Any of these signs calls for an immediate change of the parts as they inhibit its performance.

Extreme temperature emissions-The cases of extreme temperatures show a problem with the cooling system or a need for lubrication.

Insufficient end-use pressure- Depicts loose fittings, which leads to air leakages.

Dirty water during drainage- Indicates pitting in the inside of the tank resulting from corrosion.

How to Prevent, Maintain and Troubleshoot Air Compressor Defects

Regular holistic maintenance to your unit is of significance to its performance and lifespan. It is advisable to adhere to the manufacturer’s guidelines for air compressor service. Meanwhile, you should perform routine check-ups on a daily, weekly, or monthly basis. Here are the maintenance tips.

Maintenance Tips for an Air Compressor

Check Oil Levels

For smooth operation, just like your car, an air compressor requires regular lubrication. Ensure that each time you need to use your unit, check on the oil level. Most air compressors nowadays are built with oil level sight glass that allows you to observe the oil level. The oil should be halfway or above the gauge mark, and if not, add more oil for smooth operation.

Replace Filters

During a refill, the air compressor pulls in the air that at times contains specks of dust or debris, which are then trapped by the filters to prevent entry into the tank. These filters require regular change as part of servicing to enhance the performance of the unit. Ensure you check on your manual the interval the manufacturer has stated for a filter change.

Likewise, if you own an oil-based air compressor, it is fundamental to change the oil filters for the same reason. This is also indicated in the manufacturer’s manual. If not, you can call to confirm from your dealer. If you are not sure how to change a filter, use the manual or inquire from your manufacturer.

Monitor Temperature

Monitoring the temperature of your air compressor is a vital maintenance element. As you use it frequently, you are well-vast with its normal temperature. At times you can realize a drastic change in temperature to extreme conditions, which indicates a defect. If you realize such an issue, shut it down immediately and find the problem. However, some air compressors are made to shut down automatically in case of extreme temperatures.

Tighten Loose Bolts

It is usual for bolts to loosen as an air compressor works by vibrating. So, make it a routine to check and tighten the loose bolts. This will bring it back to shape and enhance its performance. Furthermore, tightening the bolts prevents unnecessary accidents that can be catastrophic.

Drain Any Moisture

As an air compressor draws air from the atmosphere, its moisture is also driven and condensed inside the tank. The water in the receiver tank in the presence of oxygen corrodes the sides.  When the internal walls become weak, pressured air can find a way out, or the tank can explode. Therefore, you must drain the tank regularly after use to avoid the build-up of moisture.

Look for Leaks

At times, straining the hose can make it loose at the connection joints leading to air leaks. Leaks reduce the air pressure; thus, the air compressor does not work to the optimum level. I will advise you to regularly check the weak points or any hole to maintain air compressor performance. If it is not repairable, you should replace the whole hose to make it work efficiently.

Check Air Quality

The air quality affects the performance of the air compressor, so it needs frequent checking. Air contamination can be due to corrosion in the system. For instance, inspecting the airlines and filters will prevent air contamination and ensure clean air flows in the air compressor system all the time.


In case you realize any trouble with your air compressor, the first option is to refer to the operator’s manual. Read through to capture the semantics of the air compressor and familiarize yourself with any possibility. You will also find additional detailed instructions on how to maintain your air compressor properly. This will keep the air compressor running smoothly.

During troubleshooting, the check-ups should run around wiring, belts, hose connections, fluid levels, pitted parts, and air inlets. Any part that shows symptoms of irreversible damage and affects the performance of an air compressor should be replaced. These symptoms shows that air compressors does devalue.

If you realize that your air compressor is working unusually, but you can’t identify the problem, you should contact a professional technician immediately. The expert will help to detect the faults and make necessary requisite repairs quickly and efficiently. This option is advantageous as it will save you the time you could have lost trying to repair it yourself. The professional will also give your more insight into the value of the parts that need replacement with time and more technical knowledge on maintaining your unit.

How to Extend the Life of Your Air Compressor

To extend the life of your air compressor is simple, perform regular maintenance and repair. However, if you do regular maintenance perfectly, you’ll not need to repair any part. So, extending the air compressor life means changing the oil regularly for smooth operation, replacing the filter, and addressing the repairs as quickly as possible.


Yes! Air compressors does devalue. Therefore, if you take care of it through proper maintenance, the air compressor will return the favor by servicing you for a more extended period.

Furthermore, if you realize any fault in the air compressor system, do not operate it as that can lead to the shutdown of the whole system. Instead, turn it off and diagnose the problem, and if you fail, contact a professional.
