You can always count on Mr. Duct arriving promptly for furnace repair and heating service, but here are a few simple things to try before calling:

Gas Furnace Equipment Checklist

1. Check to make sure that your thermostat is set in the "heat" position.
2. Make sure that the temperature setting on the thermostat is set above (or higher than) the indoor temperature showing on the thermostat.
3. Ensure that there is power to the furnace.
   • Try turning the fan to "ON" using the fan switch on the thermostat to test for power to furnace.
4. Check the circuit breakers at the electrical panel.
5. Check the SSU switch (it looks like a light switch on a gray box located at the furnace) to be sure it is in the "ON" position.
6. Check to ensure the furnace filter isn't in need of replacement.
   • All one-inch thick furnace filters should be replaced monthly.
   • Wider two-inch thick and other high-capacity pleated filters can most likely be changed every other month or just six times per year.
7. If the system is running but you have not changed your filter, the filter needs to be replaced.
8. Check all return air grilles to make sure they are not blocked by furniture.
   • Check all supply air registers to make sure they are open and blowing air. (The return air grilles are normally located on your walls and are wide and flat).
