Should I Repair or Replace My Furnace?

If you’ve been told you’re in need of a fairly costly furnace repair, it can be hard to know if you should fork out the money to fix it or just get a whole new furnace. Our Fairfax County HVAC customers often ask whether it’s best to repair or replace a furnace, and here’s when we recommend replacing it:

Your Furnace is Older Than 15 Years Old

According to the U.S. Department of Energy, a furnace should last 15-30 years before you’ll need to replace it. The length of time it lasts depends on how diligent you’ve been about keeping preventative furnace maintenance appointments, but in general you’ll start to see components breaking down after that 15 year mark.  An old furnace can be compared to an old car: it may run okay after each minor repair but you won’t be able to tell when the next problem will come.

 A Furnace Repair Costs More Than Half as Much as a New Furnace

It can be hard to spring for one big price tag on a new furnace, but there’s really no sense in putting a huge chunk of money into fixing a furnace. So if the repair will cost less than 50% of the replacement cost, go ahead and consider it, but if your furnace is beyond 3/4 of its life expectancy and you’re looking at a repair that’s close to half the cost of a new one, replace it.

Your Heating Bill is Increasing

If you notice a big difference between this year’s heating bills and last year’s, your furnace may be consuming too much energy which means it’s working harder. Its internal components will start to wear down and run less efficiently the older it gets. Remember in calculating your decision that a newer, high efficiency furnace will save on monthly energy bills for many years to come.
