Your furnace doesn\u2019t get as much of a workout as one might in, say, Michigan. <\/p>\nYour furnace doesn\u2019t get as much of a workout as one might in, say, Michigan. <\/p>\n
But that doesn\u2019t mean you completely ignore your furnace either. It\u2019s still a source of significant potential energy loss. <\/p>\n
So, how do you know when you should replace your furnace so you have an energy-efficient one? <\/p>\n
Truthfully, there\u2019s several signs. And here\u2019s what to look for: <\/p>\n
1. Age<\/strong><\/p>\n Furnaces can last 20 years, and even longer. But you should at least begin to consider replacing your furnace when it becomes 15 years old. <\/p>\n The typical furnace lasts around this long before requiring significant repairs or conking out entirely. <\/p>\n And usually, 15 years is more than long enough for industry innovations to substantially improve energy efficiency for furnaces. <\/p>\n An old furnace can also possibly be dangerous. A faulty heat exchanger could lead to a carbon monoxide leak. The pilot light could start a fire in your home. <\/p>\n So once your furnace hits 15, at least begin thinking about replacement. <\/p>\n 2. Uneven Heating<\/strong><\/p>\n If your home feels hotter or colder throughout, you have a good chance of having an old furnace. <\/p>\n You could also have poor insulation or ductwork. And you could have a furnace that\u2019s too small or large for your home. <\/p>\n Anyway, uneven heating certainly may indicate the need for a new furnace. So, it\u2019s a good time to do a home energy audit and figure out if your furnace is the problem. <\/p>\n 3. Repairs Have Increased a Lot<\/strong><\/p>\n What\u2019s \u201ca lot\u201d mean? <\/p>\n If your furnace has had many more repairs in the last couple years, that\u2019s a sure-fire sign your furnace is on its last leg. <\/p>\n If this describes your situation, you have no doubt it\u2019s time to look for a new furnace. <\/p>\n Besides, a new one will cost you less to fix in the long run and give you more peace of mind right now. <\/p>\n
