When your furnace stops working in the middle of a Frederick County winter, it's more than an inconvenience—it can be dangerous. Temperatures inside your home can drop quickly, putting your family and your pipes at risk.
Before you panic, follow this emergency action checklist. Some furnace problems have simple fixes you can do yourself, while others require immediate professional emergency service. Either way, we'll help you stay safe and get your heat restored as quickly as possible.
⚠️ Safety First: When to Evacuate
Before troubleshooting, check for these dangerous situations that require immediate evacuation:
Smell gas?
Leave immediately, don't use any electrical switches, and call 911 from outside.
Carbon monoxide alarm sounding?
Evacuate all family members and pets, then call 911.
See smoke or flames?
Turn off the furnace at the switch, evacuate, and call 911.
Hear loud banging or popping?
Turn off the system and call for professional help—don't restart it.
If none of these apply, proceed with the troubleshooting checklist below. If you're ever unsure, call us at (301) 555-1234—we're available 24/7 to help you assess the situation.
Emergency Troubleshooting Checklist
Follow these steps in order. About 20% of "emergency" furnace calls can be resolved with these simple checks:
Check your thermostat
Ensure it's set to "Heat" and the temperature is set higher than the current room temperature. Replace batteries if it's battery-powered.
Inspect the circuit breaker
Look for a tripped breaker in your electrical panel. Reset it once if tripped, but if it trips again, call a professional.
Check the furnace power switch
Many furnaces have a wall switch nearby that looks like a light switch. Make sure it's in the ON position.
Inspect the air filter
A severely clogged filter can cause the furnace to shut down. If it's dirty, replace it and try restarting.
Check the pilot light or ignition
For older furnaces, the pilot light may have gone out. Modern furnaces have electronic ignition—listen for clicking sounds.
Look at the furnace display
Many furnaces have LED displays or blinking lights that indicate error codes. Note these for the technician.
Furnace Still Not Working?
If you've tried the checklist above and your furnace still won't start, you likely have a problem that requires professional repair. Common issues include:
Ignition Failure
Faulty ignitor, flame sensor, or gas valve issues
Blower Motor
Motor failure, capacitor issues, or belt problems
Control Board
Electronic control failures or wiring issues
Our technicians can diagnose and repair most furnace problems in a single visit.
