With winter weather bringing cold nights and the occasional bout of snow,
it’s no time for a furnace disaster. Fortunately, there are signs
that will let you know when it’s breaking down before it quits completely.
So, how can you tell you
need a new furnace
A typical furnace lasts approximately 15-20 years. If your furnace is
in that last five years of life, you should minimally get it serviced
every year. The better bet is simply to replace the furnace. It eliminates
the guessing game of how much longer will it last.
Increasing Number of Repairs
Another good sign that you should replace the furnace is when it needs
frequent repairs. Those ongoing repairs are a firm signal that the machinery
is simply wearing out. While you can probably limp the furnace along for
another year or two, sooner or later it will just die.
Sharp Increase in Your Utility Bill
While heating costs fluctuate from year-to-year, the price differences
should be predictable based on electricity or gas prices. If you see a
sudden spike in your utility bills that you can’t explain, it’s
a sign that something has probably gone wrong with your heating.
Your furnace is a machine with moving parts inside it. If it starts making
loud squeaks, rattles, groans, or banging noises, there’s a good
chance your furnace is on its last legs. You should certainly get it looked
at by a repair specialist, but assume a new furnace looms on your horizon.
It Runs All the Time
An efficient furnace cycles. That means it runs for a while to bring the
temperature up and then turns off. If your furnace runs constantly, it
means there’s a serious problem inside it.
Most furnaces will last for years, but things do go wrong with them. Don’t
ignore warning signs. Get the furnace looked at and, if necessary, replaced.
You sleep better and warmer at night.
