As we gear up for the holiday season, along with turkey, eggnog and holiday lights, we can expect temperatures to dip. The last thing you need is a holiday HVAC emergency, when you are ready to open your gifts! If your furnace isn’t turning on, you will want a game plan in your back pocket. 

You can always contact us at Jack Kiefer Heating & Air, any time of the day or night. But, you may want to try our troubleshooting tips first when your furnace isn’t turning on. Are you ready to become an HVAC detective? Then, read on!

Check Your Circuit Breaker

There should be a circuit breaker that is dedicated to your furnace. If your heat isn’t kicking on, check for a tripped circuit breaker. This most often happens when your furnace blower is working too hard. There is a common culprit that can cause this to happen, as you will see next.

Check Your Air Filters

When your furnace blower is overworked, the most obvious culprit is a dirty air filter. You should be replacing the air filter on your HVAC system every three months, otherwise there could be a buildup of dirt and other particles. Any hot air produced by your furnace will have to work extra hard to blow through the clogged filter. If the blower is overheating, the furnace will kick off.  

Check Your Thermostat

First, check the thermostat On and Off setting. Make sure the thermostat is turned On. Next, is the Heat turned on? If both of these check out, then test the thermostat by turning it up by 10 degrees. This should cause the furnace to kick on. If that is not happening, you may need an HVAC expert to figure out why your furnace isn’t turning on.  

Check the Drain Pan

Most furnaces will produce condensation. A drain pan will collect the water, and if the pan is full then a safety mechanism will prevent your furnace from turning on. You may also want to see if the condensation line is plugged. You’ll know there’s trouble if you see water on the floor near the furnace. If you’d like help with these issues, we can send out an HVAC technician.

Check the Pilot Light

If you have a newer furnace, chances are that your pilot light has been replaced by an electrical igniter. However, if your furnace is 15 years or older, you’ll have a pilot light. When it goes out, your furnace won’t turn on. If you need a new electrical igniter on your furnace, or your pilot light won’t stay on, then it may be time to contact us.

Check for Gas Line Problems

An easy way to tell if there is a problem with the gas line to your furnace, is to turn on a different gas burning appliance, like your stove. If other gas appliances are working, you may want to call a professional to see if the gas line to your furnace is disrupted. If you smell gas, or suspect a leak, evacuate your home and immediately, and contact your gas company.
