While there is no standard answer to how long a furnace will last, there are several variables that must be considered. Typical variables include the quality level of the installed unit and how well the furnace is maintained. As a rule, working with a quality HVAC service provider will extend the life of most heating units, but there are also some basic questions any homeowner should be asking about their furnaces.

What Lifespan is Considered Typical for a Furnace?

Normally, a modern furnace can be expected to last somewhere around 20 years but, as suggested above, that figure depends on the quality of the furnace and how what sort of maintenance is provided. Electrical components and some smaller parts may well need to be replaced at some point during the life of a furnace, but technicians certified by the North American Technician Excellence (NATE) work with homeowners to make sure their furnaces are kept in peak operating condition. They are trained to spot issues early that tend to cause a furnace to fail under use and take the steps needed to prevent problems from developing.

The big problem that typically requires a new furnace installation is a failure of the heat exchanger. The heat exchanger is, essentially, the box in the furnace where the burner is located. Eventually, the stresses from constant heating and cooling cause the heat exchanger to crack, meaning there is a distinct danger of carbon monoxide being distributed throughout the home. Because of the expense associated with replacing a heat exchanger, industry experts routinely recommend a new heating installation rather than repairing the damaged unit.

What is Involved in Replacing a Furnace?

First, the technician will evaluate the home to make sure the furnace selected is actually the correct size for the property. Furnace installation professionals will also carefully check the existing duct system to make sure it can efficiently distribute the heated air and return cooled air to the furnace. At that point, the heating and cooling expert will recommend alternatives that will provide the best performance and yield the longest life.

If your furnace is reaching the end of its useful life, consider the offerings from Enviro Air HVAC before making any replacement decisions. When exploring the options for new furnaces available, consider not only the initial cost but also the efficiency of the unit, as a high-efficiency unit will cost considerably less to operate. Lower operating costs quickly make up the difference in cost between an entry-level furnace and a high-quality unit. To get started, contact the experts for advice today.
