As a seasoned expert in the HVAC industry, I am frequently asked about the longevity of air conditioners. It's a valid concern, as no one wants to be left without a functioning air conditioning unit during the scorching summer months. The good news is that with proper care and maintenance, air conditioners can last anywhere from 15 to 20 years on average. However, there are several factors that can impact the lifespan of an air conditioner, including usage, location, and maintenance. A central air conditioning unit typically has a lifespan of 12 to 17 years with regular use and maintenance.
However, this can vary depending on the specific unit and its usage. For instance, in coastal areas where salt corrosion is a concern, the lifespan may be significantly reduced. Similarly, ductless minisplit systems can last anywhere from 10 to 30 years, but this also depends on various factors. One common question I receive is whether it's better to repair or replace an older air conditioner. The answer to this question depends on several factors, such as the age of the unit, the cost of repairs, and its energy efficiency.
If your air conditioner is over 10 years old and requires expensive repairs, it may be more cost-effective in the long run to replace it with a newer, more efficient model. When it's time to dispose of your old air conditioning unit, it's crucial to follow proper procedures. This includes having a professional recover any remaining refrigerant in accordance with federal law (the Clean Air Act). Additionally, regular maintenance is essential in extending the lifespan of an air conditioner. This includes tasks that can be done by homeowners, as well as regular inspections and tune-ups by a professional. One factor that can significantly impact the lifespan of an air conditioner is the quality of air in your home.
Poor air quality, filled with pollutants and moisture, can lead to mold growth and other issues within the unit. This is why it's important to regularly change air filters and have your air conditioner cleaned and inspected by a professional. So, how do you know when it's time to repair or replace your air conditioner? There are a few telltale signs to look out for. If your monthly energy bill has significantly increased, it may be a sign that your air conditioner is no longer functioning efficiently. Similarly, if you notice that your home feels more humid than cool, it could be a sign of an inefficient air conditioning unit.
