Pipelines usually last 10 to 15 years in most homes. Ducts over 15 years old should be replaced to prevent pests, voids and drafts, so that the temperature in your home is always comfortable. In most homes, ductwork lasts 10 to 15 years before problems occur. If the ducts are more than 15 years old, have them replaced before serious problems occur, such as pests, voids, or even collapsed sections of the ducts.
That way, you can prevent drafts or congested areas and ensure that all parts of your home remain comfortable. 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 sooner than 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 building materials of the house, are corrosive to the copper elements of the condenser; they can cause them to erode and decay. The size of the unit does not affect the lifespan of the air conditioner, unless it's not 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 if you had a properly sized (but more expensive) unit. On average, an air conditioning system can last between 10 and 25 years, depending on several factors.
If you keep up with suggested maintenance, the average life expectancy of commercial HVAC systems is 15 to 20 years. However, just as your bones, heart, and circulatory system don't work as effectively if you don't exercise, eat properly, and get enough sleep, your commercial air conditioning system will wear out more quickly if you don't perform maintenance and repairs. necessary.
