Frequently Asked Questions

How many years does a furnace last?

There’s no single answer for this, as it depends on many factors. A gas furnace can last as few as 10 years or as many as 30 without needing replacement. Newer models are designed more efficiently and robustly, meaning they’ll last longer. Older models may have shorter life spans and a lot of baked-in energy inefficiency and waste.

While your 20-year-old furnace may not be completely nonfunctional yet, and it might keep going for years more, an old system can be wasting nearly a quarter of the energy you put into it.

The service life of a gas furnace is also shaped by how much maintenance it’s gotten, your indoor air quality, how often you update and clean air filters, and more than a little luck.

Is it cheaper to replace the furnace and AC together?

While you can replace your AC without replacing your furnace, it will almost always save money to upgrade multiple components at the same time. Not only do the two share an air handler in most designs, it’s less work for technicians to replace your air conditioner while they’re already working rather than replace each separately.

You can expect to save 10% or more by replacing them together in most cases, barring unusual circumstances in your home’s installation or your target upgrade. Of course, this assumes both need upgrades, which may not be the case if they were installed at different times. 

Will a furnace work without an AC unit?

You can have a stand-alone furnace installed without air conditioning if you don’t need air conditioning or have a separate system for cooling like window units, mobile AC, or ductless mini-splits.

It’s easier to add an air conditioner to a home that already has a furnace than vice versa, as most systems that include a furnace and central AC use the furnace’s air handler to push air through the ducts. The air conditioner acts more like an add-on to that system.
