Furnaces are rugged and durable appliances that are built to perform like champions on even the frostiest January nights.
But over time, your furnace will wear down and gradually wear out. And even if it doesnâ€™t, your needs and expectations may evolve, and a furnace that seemed like a solid, quality performer a few years ago might be less than adequate now.
Of course, getting a new furnace requires a significant financial investment, including installation costs as well as the price of the equipment. Before you lay out that kind of coin, youâ€™ll want to be 100 percent sure the time is right to make a change.
So how will you know when your furnace is on its last legs and just about ready for the scrap heap? Here are five good indicators â€¦
Â Â Â Â Â 1. Advanced age
With few exceptions, furnaces in general tend to wear out after 10-15 years of steady functioning, although early and obvious signs of damage or decay may not be detectable. Another factor to consider is that each new generation of furnace is more energy-efficient, and therefore more cost-effective, than the last, and the opportunity to cut your monthly fuel costs by 40-50 percent may be too good to pass up. Despite the upfront costs, a brand new energy-efficient furnace could pay for itself in less than 10 yearsâ€™ time, depending on the quality and efficiency of the unit it is replacing.
Â Â Â Â Â 2. Escalating fuel bills
Have your home heating bills been creeping upward beyond the rising cost of fuel? Progressive changes like this are the mark of a furnace in crisis, and if you donâ€™t take action, the problem will only get worse. By all means, you should consult with your HVAC contractor before making a final judgment, but if they canâ€™t find a single mechanical problem that explains the excessive fuel usage, a general systemic decline is the likeliest explanation.
Â Â Â Â Â Â 3. More frequent services calls for repairs
Repeatedly patching up a failing appliance makes no economic sense. When things reach the point where youâ€™ve got your HVAC contractorâ€™s emergency repair line on speed dial, it might be time to start working on the epitaph for your furnaceâ€™s tombstone.
Â Â Â Â 4. Strange noises, odors, leaks, or soot accumulation
These are symptoms of a furnace thatâ€™s gradually crumbling into dust, the forces of entropy and heavy use stressing it to the breaking point. In a sense, these are like the small tremors that often precede a giant earthquake, and they should motivate you to take action before disaster strikes.
Â Â Â Â 5. Uneven heat distribution
Hot spots, cold spots, and temperature differentials throughout the house could mean one of two things: either your furnace is improperly-sized (too big or too small for your home), or it can no longer kick out and distribute heat at a consistent rate. If temperature anomalies are a new phenomenon, it means the latter is the problem, and thatâ€™s a clue your furnace is losing its battle with Father Time.
