How long does a Furnace last

The lifespan of a furnace can vary depending on several factors, including the quality of the furnace, how well it has been maintained, and how often it is used. On average, a well-maintained furnace can last between 15 and 20 years, although some may last longer or shorter.

Regular maintenance, such as cleaning and replacing filters, lubricating moving parts, and inspecting and repairing components as needed, can help prolong the life of a furnace. It is also important to have a professional HVAC technician perform an annual inspection and tune-up to ensure that the furnace is running efficiently and safely.

Other factors that can affect the lifespan of a furnace include the quality of the installation, the type of fuel it uses, and the amount of use it receives. For example, a furnace that is used heavily during the winter months may have a shorter lifespan than one that is only used occasionally.

In summary, the lifespan of a furnace can vary depending on several factors, but with regular maintenance and care, a well-maintained furnace can last between 15 and 20 years on average.
