If your furnace or boiler is 10-15 years old, it’s already reached its average lifespan. If it’s even older and still working fine, consider yourself among the fortunate few.
But here’s the thing: no matter how old it might be – even if it’s keeping you warm and comfortable – it’s won’t last forever. Is now the time to replace it? It could be if you notice one or more of these classic warning signs:
Gas & Electric Bills Going Up?
Rising gas and electric prices are not the only reason for higher monthly bills. Furnaces often lose their efficiency as they age, especially if they haven’t been faithfully maintained.

Any Furnace Repairs Within the Past 2 Years?
A furnace is like a car. As it ages, it often feels that once you first have it repaired, other repair issues soon follow. It doesn’t take long before you’re spending $500 or more just to keep the old furnace running. Sooner or later, even one more repair just isn’t worth it.
How’s your thermostat working?
Do you feel that some rooms are too cold or too warm? Or, do you frequently adjust your thermostat hoping to enjoy greater comfort? Temperature swings from room to room usually indicate a problem with your thermostat or poor air distribution.
Is your furnace making strange noises?
Old furnaces often sound off in their declining years – the noises include banging, popping, rattling, and squealing. If the noises persist, have your furnace or boiler inspected.
How are you feeling?
As a furnace ages, it’s prone to develop cracks in the heat exchanger. Carbon monoxide, if present, could leak into your home undetected. Signs of CO poisoning include frequent headaches, a burning feeling in the nose or eyes, nausea, disorientation, and flu-like symptoms.
