Why Your Furnace Won’t Start & How to Fix It

1) Air Filter Issues

When you leave an air filter in the furnace too long, it fills up and your furnace has to work extra hard to get the air it needs. This can cause it to work too hard. Some units will shut off when they have to work so hard, while others will break down. If your furnace won’t start, try changing the air filter and see if that helps. Learn how to change a furnace filter here!

2) Your Pilot Light Went Out

Check for a blue flame near the bottom of your furnace, or wherever the pilot light is located on your unit. Without this, your furnace won’t turn on. If it’s out, relight it if you know how or call us for help.

3) The Gas Supply is Too Low

Make sure your gas supply is turned all the way on. Your furnace can’t work without this. Some homeowners think it’s safer to turn this part of the way off, but this only ends with your furnace not working. It should be all the way on or all the way off.

4) The Thermostat Got Reset

Make sure your thermostat is set where you want it to be. If it got bumped, it could be the reason why your furnace won’t turn on. You’d be surprised how often we diagnose this as the problem behind a furnace breakdown.

Lightfoot came out to check my thermostat that was installed 18 mo ago with our new system because it wasn't connecting online so I could adjust heat/cooling while away. Turns out that likely one of the power outages damaged the thermostat. Justin tried to fix it (just as I had tried) by re-setting the WiFi and resetting the thermostat but no luck. After speaking with the office, he installed a newer/more expensive thermostat in its place. I did have to pay for the labor. I have a new thermostat and everything is working great. I appreciated Justin's communication with me on my options.
Very professional services. Will use them again
Eldon did a great job with a new HVAC installation and explained everything with detail. Will be using them for all future HVAC needs.
Overall excellent experience from the appointment that was made via a phone call through the service visit by Josh. Professional, efficient, and communicated well the entire time. I'll definitely return to Lightfoot for future HVAC needs.
Had a plumbing issue and Nathan took care of it and was very respectful and friendly. Good experience for an unfortunate event.
had Lightfoot install a Generac on my house. Technicians were very knowledgeable and worked with me on where to position the system. Work was done in a timely manner and finished up with a walk through to make sure everything was working as it should be. Would recommend/ use Lightfoot Mechanical for future HVAC/Electrical/plumbing issues.
Always professional and thorough
Very prompt, honest reliable and helpful! They diagnosed and fixed our issue the same day!
