Take These Steps Before You Pick Up the Phone
A technician can diagnose and repair your furnace far more efficiently when a homeowner has already worked through the basics. Here’s what to check first:
1. Verify the Thermostat and Power Supply
This sounds obvious, but it’s the first thing a technician will ask about! Confirm that the thermostat is set to heat mode and that the temperature is set above the current room temperature. Check that the display is active and responding.
From there, check the furnace’s power switch. It looks similar to a standard light switch and is usually mounted on the wall near the unit. Confirm it’s in the on position. Then check your home’s electrical panel for a tripped breaker on the furnace circuit.
These three checks take less than two minutes and resolve a surprising number of service calls before they happen.
2. Check the Filter and the Flame Sensor
A severely clogged air filter restricts airflow enough to trigger an automatic safety shutdown. Pull the filter and hold it up to a light source.
If you can’t see light through it, that filter is overdue and may be contributing to the problem.
While you’re near the furnace, check whether the pilot light is lit on older units. On newer units, listen for the ignition sequence when the thermostat calls for heat.
A furnace that attempts to start but shuts off after a few seconds is often signaling a dirty flame sensor. It’s one of the most common repair calls a technician handles.
3. Note Everything You’ve Observed
Before you call for furnace repair service, take two minutes to write down what you’ve noticed:
- When did the heat stop working?
- Is the furnace making any unusual sounds when it attempts to start?
- Are there any error codes or indicator lights on the control panel?
- Has anything changed recently, like a new filter, a recent service call, or unusual smells?
That information gives your technician a meaningful head start on diagnosis. A repair that takes an hour to diagnose from scratch can be pinpointed in minutes when a homeowner describes what they saw accurately.
Know What Not to Do While You Wait
A few common mistakes can make a furnace repair more complicated than it needs to be. Repeatedly cycling the power on and off can mask fault codes that your technician needs to see, for instance.
Attempting to access internal components without training also creates safety risk, particularly around gas lines and wiring.
If you smell gas at any point, leave the home immediately. Avoid using any switches or electronics, and call your gas provider from outside. That situation goes beyond furnace repair and requires an emergency response.
