The lifespan of an air conditioning (AC) compressor can vary depending on a number of factors, including the quality of the compressor, the type of compressor, and how well the system is maintained.

On average, an AC compressor can last anywhere from 8 to 20 years, with a typical lifespan of around 10-15 years. However, compressors that are well-maintained and are of high quality can last longer, up to 20 years or more.

The factors that can affect the lifespan of an AC compressor include:

• Quality of the compressor: Compressors that are of high quality and are made with durable materials tend to last longer than those that are made with lower-quality materials.
• Type of compressor: Scroll compressors tend to last longer than reciprocating compressors.
• Usage: Compressors that are used frequently or that are used in extreme temperatures may have a shorter lifespan than those that are used less frequently or in more moderate temperatures.
• Maintenance: Compressors that are well-maintained, with regular cleaning and oil changes, tend to last longer than those that are not well-maintained.

It’s always recommended to have the compressor and the whole AC system checked by a professional regularly to keep the system running efficiently and to prolong the life of the compressor and the system as a whole.

Is it worth replacing compressor on AC unit?

Whether or not it is worth replacing the compressor on an air conditioning (AC) unit depends on a number of factors, including the age of the unit, the cost of the replacement compressor, and the cost of other repairs that may be needed.

Here are a few things to consider when deciding whether or not to replace the compressor:

1. Age of the unit: If the unit is old and nearing the end of its expected lifespan, it may not be worth the cost to replace the compressor. In this case, it may be more cost-effective to replace the entire unit.
2. Cost of replacement: The cost of the replacement compressor and the cost of labor to install it should be considered. If the cost of replacement and labor is too high, it may not be worth it to replace the compressor.
3. Additional repairs: If the compressor is the only issue with the unit, and all other components are in good working condition, it may be worth it to replace the compressor. However, if other repairs are needed, it may be more cost-effective to replace the entire unit.
4. Energy efficiency: If the unit is old and not energy efficient, it may be worth it to replace the compressor and the whole unit to get a more energy-efficient AC system.

In general, it’s recommended to have a professional evaluate the AC unit and provide an estimate for the cost of repairs or replacement. A professional can help you determine if it’s worth it to replace the compressor or if it would be more cost-effective to replace the entire unit.
