Furnace Repair Checklist
1. Check the Thermostat
To start, make sure your thermostat is telling your furnace to start.
Digital Thermostat
Replace the batteries if the screen is blank. If the digital screen is jumbled, the thermostat may need to be replaced.
Make sure the switch is set to “heat” instead of “off” or “cool.”
Ensure the program is displaying the right day and time and is set to “run.” If you’re having a hard time overriding the program, set the temperature by using the up/down arrows and press the “hold” button. This will cause the furnace to start if thermostat programming is causing a problem.
Increase the temperature setting to 5 degrees warmer than the room temperature.
If your furnace hasn’t kicked on within a couple minutes, make sure it has power by toggling the fan switch from “auto” to “on.” If the fan doesn’t start, your furnace might not have power.
Smart Thermostat
If you have a smart thermostat—like one made by Nest, Ecobee, Lux, Honeywell or Bosch—troubleshooting is very model-specific. Check the manufacturer’s website for help. If you still can’t get your Wi-Fi thermostat to work, call us at 321-205-1234 for heating and cooling service.
