8 Warning Signs of a Failing Furnace

Cold streaks like what we recently experienced make us beyond grateful for our heating systems. However, the fact remains that they can’t get us through the winters forever. Do you know how to tell if it’s time to repair or replace? To help, we put together this guide to warning signs of a failing furnace.

Furnace is Over 15 Years Old

Depending upon fuel type, a furnace’s average life expectancy is 15 to 20 years according to Consumer Reports. Older systems already have lower efficiency ratings, and performance degrades significantly with age. On the other hand, today’s HVAC systems feature updated technology for enhanced safety and efficiency. Once your unit reaches that 15-year mark, start using more caution and consider an upgrade.

Inefficient or Uneven Heating

Your furnace should warm the whole home evenly; experiencing cold spots or some rooms feeling hotter or colder than others mean there may be something wrong with the heating system. While this may be due to ductwork issues or inadequate insulation, it can also be caused by mechanical problems with the furnace itself.

If you notice a decrease in heating performance, one of Stafford’s professional HVAC technicians can diagnose the issue and help you find the ideal solution.

Unexplained Rise in Utility Bills

Nobody wants to be surprised by a spike in utility costs, and it can also indicate trouble with your furnace. When something is damaged or wrong with the system, it has to work harder – and burn more fuel – to maintain the temperature settings. Remember, inefficient or uneven heat distribution requires professional attention to address underlying issues before they get worse.

Decreased Indoor Air Quality

Properly functioning HVAC systems help keep your home’s air clean as well as comfy. It may be time for a furnace upgrade if you notice these signs of decreased indoor air quality (IAQ):

• Excessive dust accumulation in the household
• Increased irritation and symptoms of allergies, asthma, and other respiratory illnesses
• Poor humidity management leads to dry indoor air during winter

While there are ways to improve winter IAQ, don’t ignore these potential signs of a failing furnace. Call your local HVAC specialist to diagnose any issues and help you decide if it’s better to repair or replace.
