Central air conditioning systems can last between 10 and 30 years, and most average around 10 to 15 years in total (. Keep in mind that the lifespan of your air conditioner depends on how much you use it, your local climate, the type of air conditioner you have, and whether your home is well insulated and sealed. Air conditioners can last 10 to 15 years, depending on several factors, while air conditioning systems can last up to 30 years before they need to be replaced. As already mentioned, in general, air conditioners last between 15 and 30 years old.
However, more expensive items tend to last much longer. How long do air conditioners last? Central air units will last 12 to 17 years with average use and good maintenance. They tend to fail before components that produce heat because moisture passes through the system and is exhausted. The chemicals used in the system to cool and dehumidify the air, as well as the chemicals that pass through the system from the house's building materials, are corrosive to the copper elements in the condenser, which can cause them to erode and decay. The size of the unit doesn't affect the lifespan of the air conditioner, unless it's the right size for your home.
For example, if you have a small 1.5-ton air conditioner trying to cool a house that actually needs a 5-ton air conditioner, the unit will break down much faster from overuse than an appropriately sized (but more expensive) unit. The joint use of the ceiling fan and the air conditioner helps air to circulate better and the air conditioner can be configured with a lower power. Homeowners can perform some maintenance tasks, such as repairing the home air conditioner or servicing furnaces, without charges for service calls or expensive parts.
