Homeowners struggle to decide whether or not to repair their old furnace or replace it. While the decision to repair it may seem like a good choice, it will most likely end up costing even more money in the long term. 

Before you try to save up on furnace replacement costs by opting to repair it, here are some warning signs you need to look for that point to a furnace replacement as being your best option:

The Furnace Has Been in Use for 15 Years or More

Like other appliances around your home, a furnace has a lifespan. Gas systems have a lifespan of about 15 years, while electric systems are good for 20 years. If you've had your furnace for around 15-20 years, it may be a good time to replace it. 

Your Heating Bill Has Increased

Damaged or old furnaces are neither efficient nor effective and will end up costing you more. Check your bills to see if they’ve increased from the previous year. A fractional difference is probably fine but if you notice a difference of 10% or more then you need to have the furnace checked. 

Your Furnace Makes Strange Noises

You can tell your furnace is not in good shape the moment it starts to make strange noises. You can typically diagnose the problem from the type of noise the furnace makes. 

• 
  Popping: The popping noise is produced by its parts as the temperature fluctuates within the furnace. 
• Screeching: This signals that a part of the furnace has been damaged, and it is either the blower motor, belt, or pulley. 
• Rattling: Produced by the movement of a loose duct or another part within the furnace. 
• Humming: It is common for the blower motor to produce a low humming noise. If you notice it getting louder, however, then it means your furnace is getting old and needs replacement. 
• Boom: Sounds of small explosions are usually due to gas emission problems when there is a delay in the ignition. If you notice a lingering gas odor after the sound, then you need to have the furnace checked immediately for a gas leak. 
• Clicking: This sound indicates a problem with the igniter or flame sensor.

Your Furnace Needs to Be Repaired Frequently

A furnace that refuses to work or experiences frequent breakdowns needs immediate replacement. If it breaks down more than once in a quarter, you should replace the furnace. Otherwise, you will be throwing your money away repairing it over and over again. 

Your Furnace Flames Are Yellow Instead of Blue

A maintained furnace will always produce blue flames. Blue flames indicate a safe and efficient combustion process. Yellow flames, on the other hand, mean that there is an imbalance in the amount of oxygen and gas being used in the furnace or even a gas leak. Have an HVAC expert come in to diagnose the problem and let you know the best way to fix it. 

Your House Isn’t Warm Enough, or There Are Temperature Fluctuations Throughout the Home

The last sign that you should get a furnace replacement is its inability to heat the whole house. You will notice some rooms are warmer than others.
