How Long Do Home Furnaces Last?

A rough estimate of the lifespan of a residential furnace is 12 to 35 years. However, numerous factors can affect this heating equipment’s actual longevity in positive or negative ways. The most important considerations include the fuel type and how often you maintain a system.

Major Types

Many gas models remain in service for 12 to 25 years. On the other hand, you can expect an oil furnace to last around 14 to 23 years. Electric units cost more money to operate, but they frequently offer the best life expectancy. These systems often perform well for 22 to 28 years before needing replacement.

Installation

It’s crucial to select an experienced, reputable furnace installer because the contractor’s skills could have a big impact on the lifespan of your system. Correct duct and vent placement hold importance, and it’s also crucial to install a heating unit of the appropriate size. Equipment quality plays a significant role as well.

Maintenance

Regular upkeep can help this machine last considerably longer. For example, you should be sure to replace or clean the air filter when necessary. Ask a trusted HVAC technician to perform a yearly tuneup, and request service as soon as your system begins to exhibit any signs of mechanical problems.

Usage

Like most equipment, a furnace will have a shorter lifespan if you run it frequently. Outdoor temperatures, home insulation, sealing, windows, doors, supplemental heaters and personal temperature preferences have an impact on longevity. Even if it doesn’t affect usage, excessive humidity may harm heating systems by causing metal components to rust.
