Factors That Affect the Life Span of a Furnace

The life span of a furnace isn’t set in stone; it can vary based on several factors. Here’s a quick rundown of the factors that can impact the life span of your furnace:

  • Quality of installation: A properly installed furnace is more likely to have a longer life span.
  • Frequency of use: The more frequently a furnace is used, especially during harsh winter conditions, the more wear and tear it experiences.
  • Regular maintenance: Routine maintenance can help extend a furnace’s life span and keep it in prime condition.
  • Size of the unit: A furnace that’s too small for your home’s heating needs may have to work harder, leading to a shorter life span.

Signs of an Aging Furnace

As furnaces age, they show certain signs that indicate they may need attention or replacement. Look out for these signs:

  • Decreased efficiency: If your furnace isn’t heating your home as effectively as it used to, it might be a sign of aging.
  • Deteriorating indoor air quality: An aging furnace may contribute to poor indoor air quality, causing respiratory issues and discomfort.
  • Higher energy bills: If your energy bills are rising without a clear explanation, your furnace could be losing efficiency.
  • Lack of even heating: Uneven heating throughout your home can be a telltale sign that your furnace is struggling.

Extend the Life Span of Your Furnace With These Maintenance Tips

To ensure your furnace stays in top condition for as long as possible, follow these maintenance tips:

  • Change the air filter regularly: A clogged filter can strain your furnace and reduce efficiency. Change it regularly.
  • Professional maintenance: Schedule professional maintenance at least once a year to catch potential issues early.
  • Inspect flames: Check the color of the flames in your furnace. Blue flames indicate efficient burning, while yellow or flickering flames may signal a problem.
  • Vents & chimney: Ensure vents and the chimney are clear of debris and free of holes or gaps.
  • Smoke & carbon monoxide detectors: Regularly test and replace batteries in smoke and carbon monoxide detectors to ensure your safety.
  • Thermostat: Make sure the functions, settings, and fan speeds are working properly.

What To Consider if You Need a Furnace Replacement

When it’s time to replace your furnace, choose a new furnace that’s the right size for your home to ensure optimal efficiency. Look for a furnace with a high efficiency rating to save on energy costs and consider your specific heating needs, especially in colder climates.
