This is a question homeowners are faced with. If you’ve repaired your furnace many times, or maybe your furnace has gotten older and has no quirks that it didn’t use to have, then you’ve probably asked yourself the question—should I replace my furnace? 

Save time and money by knowing when to replace your furnace. It might be time to stop hoping that your furnace can be repaired. But how can you be sure? Let’s look at some signs that it’s time to replace your furnace.

My furnace is making loud noises when it’s running.

There are several reasons your furnace could be making noises. Not all noises mean that you should replace your furnace. Some noises are easily fixed by calling a furnace repair technician. But there are a few noises that mean you need a new furnace.

# Humming: If you hear a loud humming coming from your furnace, this could mean it needs to be replaced. The furnace blower motor usually causes this.

# Popping: This sound isn’t necessarily a cause for concern. This can result from the temperature change affecting your furnace’s parts.

# Clicking: A clicking sound often means your flame sensor needs to be replaced. It could also mean your ignitor is going out. This is an easy repair that any technician can handle.

# Booming: This could mean that you have a large amount of gas emission from your furnace, which will need to be replaced.

# Screeching: This sound could indicate that your furnace motor blower is broken and needs to be replaced.

My furnace is more than 20 years old.

The average furnace lasts from around 15-30 years old. So if your furnace is over twenty years old and is experiencing constant problems, it may be time for a new one. Newer furnaces last much longer and can easily reach thirty years old.

My furnace isn’t producing consistent heat.

Your furnace's primary function is to keep your home warm. If you notice the temperature fluctuating, you could have something wrong with your furnace. Fluctuating temperature can be a severe problem and might mean you need a new furnace. 

My furnace is heavily affecting my energy bills.

As furnaces get older (past the 15-year mark), it becomes harder for them to produce heat efficiently. This can weigh heavily on your electric bills and make them skyrocket. Have a professional assess your furnace and let you know if you need a replacement furnace.
