The lifespan of your furnace is planned obsolescence.  Obsolescence is the term used to refer to something that is either out of date, or no longer in line with market requirements like fuel efficiency.   As it relates to an investment in a furnace, there are three types of obsolescence:  functional, economic, and physical.   Obsolescence impacts both the risk profile of an investment and the capital needed to maintain a furnace.

Economic Obsolescence

A furnace becomes economically obsolete when it loses value due to some external factor such as a change in operation time or fuel consumption.  In most cases, a property owner has no control over economic obsolescence.  However, they can be aware of impending disability and take steps to avoid it.  Knowing that the furnace will need replacement in 15 to 20 years, will let you save up for the replacement proactively.  Ocean County Furnace Replacement can help with financing and advice for proactive saving.

Functional Obsolescence

Functional obsolescence is when the furnace loses market value due to some element of its design, changing market tastes, or function.  To illustrate this point, the market has changed to materials that are sustainable and energy efficient.  If there is any, the good news about functional obsolescence is that it is curable, meaning it can be fixed.  A new owner could purchase a fuel-efficient furnace that uses renewable energy. Ocean County Furnace Replacement has this type of value-add effort usually has a positive impact on the furnace’s market value.

The U.S. Environmental Protection Agency (EPA) provides residential furnace program requirements and efficiency criteria on the ENERGY STAR website. Manufacturers meeting these requirements are allowed to display the ENERGY STAR label on complying models.  Federal buyers can use ENERGY STAR’s list of certified residential furnaces to identify or verify complying models.

Physical Obsolescence

A furnace can become physically obsolete when its valuation declines due to mismanagement or some type of physical neglect that results in a condition that is incredibly expensive to repair.  In some cases, the repair bill could be large enough that it may be cheaper to replace the furnace.  Rust, leaks, dirt or soot indicate the need for repairs.  Cold rooms or cold spots in rooms indicate the need for a larger system.  Humidity problems and rising energy bills indicate a need for replacement.

If it is curable, it can be fixed.  If it is incurable, it cannot, and furnace replacement is the best option.  Furnace warranties from the manufacturer require annual maintenance done by a reputable HVAC company.


From a risk standpoint, understanding potential types of obsolescence can help to establish the risk profile of a real estate investment.  This is exactly why an older property is less expensive than a newer one, because there is more risk associated with it becoming obsolete in some way.  When purchasing a home, risk should be assessed by knowing the age of the HVAC system.


From a cost perspective, understanding obsolescence is important because it allows homeowners to have a better sense of what it could or would cost to cure some amount of obsolescence.  In other words, a ten-year-old furnace may have only five more years of operation which will cost the new homeowner maintenance for five years, and replacement in five years.

Impact of Obsolescence

Regardless of the type of furnace, the impact of obsolescence tends to be the same, obsolescence causes the value of a furnace to decline.  A furnace becomes functionally obsolete, the value may not decline right away or all at once.  This is a scenario that could play out slowly, over a number of years with multiple repairs and expense.
