Different contractors disagree about the specific length that a unit can last. However, many agree that a timeframe that is solid for an air conditioner is between 10 to 15 years. Having said that, we have personally seen a number of older units that faithfully keep homes and businesses cool year after year.
Many of these units receive annual checkups to ensure that everything is running well. If an air conditioner needs to be replaced, we are more than willing to make helpful recommendations to customers about the type of cooling unit that would be fantastic for a business or home.
