Why is My Furnace Not Heating Properly?

Even as we enter the end of the heating season in Portland, OR, your furnace may begin to lose its ability to heat your home. This can be disconcerting, even as spring approaches.

One of the most common questions we hear from customers is “Why is my furnace not heating?” Let’s take a look at some common causes:

  • Thermocouple. Your thermocouple is an electronic safety device that typically attaches to your pilot light to prevent gas from entering the combustion chamber without a flame to ignite it properly. It may be broken, or it may be accurately sensing that your pilot light is out, in which case it needs to be relit, or your fuel supply valve is blocked by debris.
  • Electrical issue. While your furnace creates energy from fuel, it is powered by electricity. Your furnace may have tripped the circuit breaker or blown a fuse. If your wiring is old or has been damaged, this can be a potentially hazardous situation and should be dealt with as soon as possible.
  • Clogged air filter. If you notice that your furnace turns on, but little to no heat emerges from the ductwork, your air filter may be dirty or completely blocked. If you can’t remember the last time you checked your air filter, it’s a good idea to do so regularly. It’s an easy and cost effective maintenance task.
  • No fuel. While this seems obvious, customers unfamiliar with how their heating system may forget to check their fuel gauge. No fuel, no fire, as they say.
