Why Your Furnace Won’t Blow Hot Air

Problems With Your Thermostat

Believe it or not, a wrong setting on your thermostat could be why your furnace isn’t working. Check the device to see that it’s on and set to “Heat” instead of “Cool.” If it is, turn it up a few degrees to test it—it could be that your home is already at the temperature you set. Lastly, make sure the batteries have enough juice. It sounds silly, but a new set of batteries could be just what you need to turn up the heat.

A Dirty Air Filter

Have you replaced your furnace’s air filter recently? That filter acts as a safety net, catching airborne contaminants that flow through your ducts and preventing them from re-circulating. However, in the process, those contaminants can clog up the filter and block warm air from ever reaching you. So if you haven’t already, replace your filter now—and do so every one to three months for best results.

Loose or Broken Parts

This one will be easy for you to diagnose but hard to fix without one of New Berlin Heating’s experts on the scene. Listen carefully to your system—if you hear a rattling, grinding, or clanking sound, something inside the unit is either loose, broken, or worn down. Your best bet? Call in one of our experts. We’ll open up the system, take a look inside, and fix the problem efficiently.
