This is a common question among many homeowners today. Whereas there is no definite time they are supposed to last, there are industry-accepted standards that can be used as a basis for their lifespan. Typically air furnace exchangers are supposed to last for at least 15 years. However, this can vary depending on the model and the build quality.

Older furnaces with metal heat exchangers can last for approximately 30 to 40 years. However, these furnaces are inefficient compared to their counterparts despite their longevity. Today, steel heat exchangers are more common with their average lifetime being 15-25 years.

Extending the Life of Your Furnace

What can you do to make your furnace last longer?
Furnaces will gradually depreciate, and their efficiency level will drop due to constant heating and cooling. However, you could make last longer with better handling and maintenance. Here’s what you can do;

  • Proper maintenance: Regular furnace maintenance by a certified heating and cooling expert can help your furnace last longer.
  • Regular filter changes: Dirty filters restrict the amount of air your furnace gets which can cause it to overheat and lower its lifespan. Changing your filter at least every three months will ensure your furnace lasts longer.
  • Controlling moisture levels: High moisture levels can accelerate the rusting of your heat exchanger, which subsequently lowers your furnace’s lifespan.
  • Find a reputable company to install your furnace: A reputable heating and cooling professional will consider climate, your home’s size and properly estimate your heating needs before installing a furnace in your home. A well-installed furnace will last longer.

When should a furnace be replaced?

There is no definite time to replace your furnace. Consider replacing it when you notice a considerable decline in its efficiency. Also, watch out for indicators such as noise and constant breakdowns.

All three technicians worked well together. They treated each other kindly and were thoughtful and courteous with me. They did a final and complete cleanup after the installment of my new heater. They were respectful of my home. I’m grateful I used this company.

Evans Mechanical is an excellent service committed to customer satisfaction and guaranteed quality workmanship. Our water heater burst and they were very responsive. They sent a technician out the same day and it was determined the heater was beyond repair.

Excellent service from start to finish. Joe came out to give us an estimate on what we would need for a new furnace, never pressured us to buy the top of their line just giving us options on what we would need for our home. Then the date set for installation Thomas and Ryan came out on time and did a great job.
