With temperatures starting to drop, we recommend you test your furnace NOW. There are several reasons to do so:
Turn your thermostat to the heating function and set the temperature to 5 degrees warmer than the current temperature in your home.
It should turn on and start blowing air.
It’s not uncommon to hear faint hums and some small pinging sounds from the ducts.
If something isn’t working right with your furnace, whether it’s making unusual sounds, not heating up sufficiently, or the airflow seems weaker than it should, Call on Reliance™, and we’ll help determine the best way to resolve it.
