A cold snap in Burleson can arrive overnight, and there is nothing worse than waking up to a furnace that runs but will not warm the house. The good news: a surprising number of “broken furnace” calls turn out to be simple issues you can check yourself in a few minutes.
1. Check the thermostat settings
Make sure the thermostat is set to Heat, not Cool or Off, and that the set temperature is a few degrees above the current room temperature. If it is a battery-powered model, a blank or dim screen usually means it is time for fresh batteries.
2. Replace a dirty air filter
A clogged filter restricts airflow, which can cause the furnace to overheat and shut itself off as a safety measure. Pull the filter and hold it up to a light. If you cannot see light through it, replace it. Most homes need a new filter every one to three months.
3. Look at the breaker and furnace switch
Even gas furnaces need electricity to run the blower and controls. Check your electrical panel for a tripped breaker, and look for a light-switch style service switch on or near the furnace that may have been turned off by accident.
4. Make sure the vents are open
Closed or blocked supply vents and return grilles can make rooms feel cold and put extra strain on the system. Move furniture, rugs and curtains away from vents and open any that were closed during the summer.
5. Check the pilot light or ignition
Older furnaces use a standing pilot light, while newer models use electronic ignition. If you see an error light blinking on the control board, note the pattern; it helps a technician diagnose the problem quickly. If you ever smell gas, leave the home immediately and call your gas company.
When to call a professional
