HOW LONG DO CENTRAL HEATING AND AIR CONDITIONING SYSTEMS LAST?
The average life expectancy of most equipment manufactured today is between 8 and 15 years. Top quality brands will tend to last closer to 15 years, while other brands will tend to last between 8 and 12 years. Duct systems can last anywhere from 5 to 25 years depending on the construction materials used and the quality with which it was installed. Lack of maintenance and proximity to salt air and water can greatly reduce the life span of your system. However, the most important factor in determining the life expectancy of a system is the installation. For example, a brand new, top of the line system that was installed poorly and improperly sized may only last 5 years.
