Does your furnace need to be serviced?

Check the power supply

If your furnace isn’t firing up when it should be, there’s a couple of things you can do to try and narrow down the issue. In some cases, the problem may be as simple as a tripped switch.

  • Check your furnace power switch typically located on the outside of the unit.
  • It’s possible your furnace has a blown fuse. Check for any fuses or internal breakers on your specific furnace model.
  • Ensure your thermostat is calling for heat and is properly connected to the furnace wiring.

Ensure proper airflow

If you’re experiencing reduced efficiency or output, it may be caused by an issue with airflow. You can take a couple of steps on your own to try and troubleshoot the problem.

  • Replace your furnace filter.
  • Boxes, laundry, dry storage, and other household items can get placed around your furnace causing insufficient airflow for your unit. Be sure to leave plenty of room around your furnace and check the exhaust pipes for any blockage.

The day after Christmas, We got all of our kids back from their other parents' houses and getting set for them to see what Santa did at home and our heat is out. We needed a repair NOW. All of the part suppliers were closed, but Brett was able to talk to other people in his network and get the part and took care of it in one visit. To me, when someone has friends in the business willing to help them help me, that's the sign of someone with a great reputation. He was super friendly, professional, and got our Christmas back on track in no time. Thank you so much, Brett!
