A furnace is like any other piece of mechanical equipment; its average lifespan is dependent on a variety of factors, including maintenance, environment, and operating conditions. On average, a high-quality, well-maintained furnace will last about 25 years.

The following are factors that can affect your furnace's lifespan.

. If you are in the market to replace an old furnace, look for a replacement unit with the Energy Star logo. In addition to meeting stringent energy efficiency guidelines, Energy Star products are also guaranteed to require fewer repairs over the course of their lifetime, assuming they are maintained as per the manufacturer's instructions.

Maintenance. Annual maintenance is the key to keeping your new furnace running as efficiently as possible, and maximizing its lifespan. During your annual furnace inspection and tune-up, the HVAC technician will perform a variety of tasks that reduce wear and tear on the mechanical and electrical parts, and correct any small or potential issues that will become larger overtime. In addition to increasing your furnace's lifespan, these maintenance appointments will also help to minimize your annual utility and repair costs.

Filter changes. Ideally, your furnace's filter should be changed once a month to reduce airflow obstructions and minimize dirt and debris circulating through the equipment. Failure to do so causes unnecessary wear and tear and compromises indoor air quality.

Moisture levels. Keep indoor humidity levels between 25 and 40 percent during the winter months, and no higher than 60 percent during the summer. If they exceed those levels, your heat exchanger will be prone to rust.

Whole-house energy efficiency. Any weaknesses in your home's energy systems will compromise your heating system by causing excessive wear and tear. Before you invest in a new furnace, or to increase the lifespan of the one you own, take a holistic approach to your home's energy efficiency. Make sure to seal air leaks, repair any airflow obstructions in your duct system, upgrade insulation, and replace old windows with their energy efficient counterparts.
