1. Age

Wouldn’t it be great if your furnace operates forever, but the reality is far from it. The average life expectancy of a furnace is between 10- 15 years. If your furnace is less than 15 years old, be sure to carry out proper servicing as per the manufacturer’s guidelines. Start paying attention to unusual functions, noises, and odors. Consult an experienced technician if any of these things happen; they can tell you how long your furnace will survive based on the diagnosis they’ve obtained.

2. Strange Noises

It’s pretty evident that HVAC units cause noise. If your unit does not you’re probably sporting a brand new unit or it’s tucked somewhere in your house where you won’t notice it. Squeaking or popping sounds could mean that something inside your unit has come loose and requires maintenance or replacement.

3. Yellow Pilot Light

Make sure your natural gas furnace’s pilot light is always blue if you have one. If your furnace’s light is yellow, it could be leaking carbon monoxide, which is poisonous and necessitates maintenance. Shut down your furnace and contact an HVAC technician as soon as you notice any of the following: a yellow pilot light, extreme condensation, grime, or a foul odor.

4. Cold Air

Even if it seems self-evident, a furnace that isn’t warming your home is a strong indicator that it will fail soon. This can be determined by a multitude of different issues, but often it’s the blower fan motor that malfunctions. If the furnace’s blower fan breaks down, it won’t be able to distribute enough air throughout the house. This can contribute to cold spots in some areas of your home.

The heat exchanger or pilot light may be unsound if your furnace fails to deliver any hot air. This is something that only an expert technician can assess in order to ascertain whether or not a repair is feasible.
