The answer to 'how long does AC last' is that a well-maintained central air conditioning system typically lasts 15-20 years. However, the lifespan of an AC unit can vary depending on factors like the climate, usage, and quality of installation and maintenance. Proper care and regular service by a qualified HVAC technician are key to maximizing the lifespan of your air conditioning system.
Most air conditioners are designed to operate for at least 10-15 years, but with diligent maintenance, they can often exceed 20 years of reliable cooling. Factors like the quality of the equipment, frequency of use, and climate conditions in your region all play a role in determining the actual lifespan of your AC unit.
