The amount of time you can expect your heating system to last will depend on what type of system it is. In general, though, it’s safe to say that a new heating system you purchase today will last you 10 to 15 years. Some types of systems, like electric furnaces, can be expected to last a bit longer, but that will largely depend on the type and model of your system. In any case, keeping up with regular maintenance is one way to extend the life of your home heating system.
