Your furnace is your first line of defense against the cold and harsh weather. Depending on where you live, you may need to run your furnace for months on end.
However, even with proper maintenance, there may be a point in time where your furnace won’t work as well as it used to. There are a lot of causes as to why a furnace stops working properly. Here are five signs that indicate that your furnace needs to be replaced.
Your Furnace is Too Old
One of the most common reasons to replace your furnace is because it’s too old. In fact, most furnaces are only expected to have a lifespan of 20 years at most. And while you can probably squeeze out a few more years of use, it’s highly suggested by HVAC professionals that you replace a furnace that’s over 15 years of age.
Your Utility Bills Are Through The Roof
Another common reason to replace your furnace is increased power bills. The reason why your bills become more expensive is because your furnace is putting out twice the amount of effort to work. This means it’s running longer just to produce heat. It might also cycle on and off more as well, which can also inflate your electric bill.
Your Furnace is Making Odd Noises
Another obvious sign that your furnace is starting to malfunction is if it starts making strange noises. Some noises that a faulty furnace can produce include popping, banging and rattling. These sounds are a sign that there’s either a problem or the furnace is nearing its end.
Your Furnace Has Been Repaired Too Much
If you have had your furnace repaired more than twice in a short time span, then you need to start thinking about replacing it. If you’ve had to constantly call a professional HVAC service, you’re better off replacing it. In fact, replacing the furnace is actually cheaper than constantly forking out money on repairs.
The Burner Flame Isn’t The Right Color
The proper color of any furnace flame should always be blue. However, if it starts to malfunction, the flame may turn a different color, such as yellow. If that’s the case, your furnace may be producing carbon monoxide, which is an odorless, invisible gas that can cause some catastrophic health issues. If you notice that the flame is a different color, replace your furnace immediately.
A furnace is an essential part of any home, so having it malfunction is the last thing anyone wants. Save yourself the aggravation as well as money by replacing your furnace when needed.
