5 Warning Signs You May Need to Furnace Replace

A healthy home requires a furnace in good working condition. Do you have a furnace that is causing problems? Is your home heating system more than 20 years old and have you spent money on furnace repairs in the last two years? If you answered yes, it may be time to replace furnace. For more ways to know if your heating system is on the fritz, check out this list of 5 signs that it’s time to replace furnace.

Sign 1:
The Age of Your System

A good place to start is to compare your furnaces age to the national average. The average life expectancy of furnaces in homes today is between 16 and 20 years. If your furnace is close to this age or older, you should furnace replace. Shopping for a replacement furnace in an emergency does not allow time to make your best decision. Most people prefer to replace their furnace as a planned home improvement rather than a panic replacement when your furnace is faltering or failed. For starters, look at your furnace to see if you have a pilot light. If you do, it is almost certain to be over 20 years old!

Sign 2:
Higher Heating Bills

Furnaces become less efficient as they age, and as a result, it raises your energy bill. Because aging furnaces are less efficient, they often run longer than normal in order to heat your home adequately. As a homeowner, one preventative measure you can take is to change the air filter every couple of months. This allows proper airflow to reach the surrounding areas. As an alternative, the US Department of Energy has several resources that can help you calculate how much money you could potentially save by replacing an older furnace if you’re tired of your rising energy bills.

Sign 3:
Strange Noises From Your Furnace

Furnaces tend to make some noise when they turn on and off, but if those noises start to get progressively louder, it may be time to replace furnace. These sounds may come in the form of popping, banging, humming, or screeching. This could be a telltale sign that you may need to replace a furnace or some parts within the furnace. The reason for some of these sounds could be:

  • Rattling: Unsecured ductwork, loose screws or sheet metal can be the cause of this sound. It may also mean the lower motor is not properly balanced.
  • Popping: This sound can happen when parts within your furnace warm and cool in response to temperature changes within your system.
  • Humming: Your fan motor may produce electrical humming sounds, but the fan should never be loud or disruptive. If it is, your inducer motor or blower fan motor could be starting to fail.
  • Screeching or Squealing: These noises are a sign there is an overall issue with your blower motor or inducer motor. Possible issues could be a loose bearing, deteriorating belt, or an issue with the pulley that holds the belt.

Sign 4:
Poor Indoor Air Quality

One of the biggest reasons to have your furnace replaced is if the existing furnace is causing health concerns to you or your family. Older units might have a significant negative impact on the indoor air quality in your home. If you notice that your family members are getting sick more often with respiratory illnesses, or are exhibiting allergy symptoms like sneezing, coughing, runny nose, or fever, this might be due to your furnace.

Sign 5:
Uneven Temperature Inside Your Home

Do some rooms feel colder than others? Are you constantly changing your thermostat so you feel more comfortable? These signs may mean your existing heating system is not able to distribute heat evenly through the house, and this is why you are experiencing these problems. If you notice any of these signs, it means you may have an old or faulty system that needs replacing.
