If you don't pay much attention to your furnace, you may not realize it needs replacement until it's too late and inconvenient. Your furnace will give some warning signs that your furnace may be approaching the end of its life span. Here's how to know when it may be time to invest in a new furnace.
Old Age
Furnaces generally last between 15 and 30 years. If your furnace is more than 15 years old and giving you trouble, it could be reaching the end of its service life. You may need to replace it in the near future.
Higher Energy Bills
A unit with one foot out the door will operate less efficiently. It will use more energy to heat your house, resulting in higher energy bills than usual.
Frequent Repairs
Furnaces usually need more frequent and costly repairs in the last years of their lives. If your old furnace has required multiple repairs recently, it may be time to replace it.
Loud, Strange Noises
A furnace making loud, unusual noises should be a cause for concern. Noises such as clicking, rattling, popping, bumping, and banging could indicate that your furnace needs repair or even that it's time for a new furnace.
Yellow Flame
The pilot flame can give you an idea of the condition of your furnace. For a functional, efficient furnace, the pilot flame will be clean and bright blue. A yellow flame is a sign that the furnace isn't burning off the gas that's entering it as cleanly as it should. A weak yellow flame could indicate that the gas isn't burning out or there's improper ventilation. You'll need to have the furnace checked as soon as possible.
Uneven Heating
Furnaces can lose the ability to deliver heat evenly to an entire home as they age, especially if they've lasted longer than 15 years. If some rooms are toasty while others are chilly, your furnace could be nearing the end of its life.
If your heating unit no longer works as efficiently as it used to, it may be time to get a new furnace.
