How Long Can an AC Unit Last? - Expert Advice on Air Conditioners

When it comes to air conditioners, the average life expectancy is between 10 and 15 years. However, with proper maintenance and servicing, some units can reach up to 40 years in extreme cases. Window air conditioners usually last 8 to 10 years, but this can vary depending on the quality and upkeep of the unit. If you're looking to replace or repair an air conditioner, it's important to understand the costs involved.

Comfort systems tend to last between 12 and 15 years in most areas, while oven and air conditioning combinations can last up to 20 years. If your unit is over 15 years old, you may need to upgrade it to meet California's minimum SEER rating of 14. When deciding whether to repair or replace an air conditioner, take into account the age of the unit, its performance and efficiency, and the cost of any repairs. For a small bedroom or guest room, look for an air conditioner with a capacity of 5,000 to 6,500 BTU, designed to cool rooms between 100 and 250 square feet. To ensure your air conditioner lasts as long as possible, it's important to keep up with regular maintenance. This includes changing the filter every month or two, cleaning the coils and fins regularly, and scheduling annual tune-ups with a professional HVAC technician.

Additionally, make sure your unit is properly sized for your home and that it's installed correctly. By following these tips and taking good care of your air conditioner, you can extend its life expectancy and get the most out of your investment. With proper maintenance and servicing, you can enjoy a cool home for many years to come.
