Is It Time to Replace Your Old Furnace?

natural-gas-furnace-open-cabinetIn our last post, we took a closer look at the warning signs a furnace needs repair work. But any furnace will eventually reach a point where doing repairs is only a minor stopgap method. The repair costs will soon outweigh the costs of keeping the furnace around.

At what point do you stop calling for repair work and instead call for a full furnace replacement? That’s the question we’re going to look at in this post. It’s the biggest question you’ll have to face with a furnace, and you want to ensure that you make the best choice.

You don’t have to make the choice alone. In fact, you shouldn’t. Contact our service technicians when you think your furnace is coming to the end of its lifespan. They’ll help you with the decision—as well as with whatever work needs to come next. 

How to know it’s time for a new furnace

There are a number of indications that it’s time to put in a new furnace.

  • Age: The best measuring stick for furnace replacement is basic age. The average natural gas furnace will last around 15 years, and an electric model may go a few years longer. But 20 years is definitely too old. We recommend having a 15 year-old furnace given a thorough check to see if it’s starting to suffer from irreversible effects of aging that will lead to a plunge efficiency and reliability.
  • Repair frequency: In general, a furnace shouldn’t need to have more than one repair a year. If you need to have multiple repair visits during the year to keep your furnace running, or the annual repair costs for the furnace is more than $500, you’re spending too much. Any repair that costs more than half the price of replacing the system is also more than you should be paying.
  • Drop in energy efficiency: One major warning of a furnace that’s in decline from age is a growing rise in the cost to run it. Compare your winter utility bills for this year to those from the previous years. If the cost is going up even though you aren’t using the furnace more often than normal, we recommend having a new furnace put in.
  • Loud operating noise: A furnace that makes a racket each time it runs is telling its owner that it’s starting to fall apart. A single strange noise often means the furnace needs to be repaired. But a general rattle, clang, and hum means the furnace needs to be retired.
  • The furnace can’t keep up: Is the furnace unable to warm up the house as well as it used to? Don’t keep turning the thermostat up if this is the case! First call for a repair technician, then find out if it’s more cost-effective to put in a new system rather than repair the old one.
