Furnace Repair Checklist

1. Examine the Thermostat

To start, make sure your thermostat is signaling your heat to turn on.

Digital Thermostat

  • Swap out the batteries if the display is empty. If the digital display is mixed up, the thermostat could need to be swapped out.
  • Ensure the button is switched to “heat” instead of “off” or “cool.”
  • Make sure the program is showing the correct day and time and is set to “run.” If you’re having a hard time getting out of the program, set the temperature by using the up/down arrows and using the “hold” button. This will cause the furnace to start if thermostat is causing trouble.
  • Increase the temperature setting to 5 degrees hotter than the room temperature.

If your heating hasn’t kicked on within several minutes, ensure it has juice by toggling the fan switch from “auto” to “on.” If the fan doesn’t begin to run, your furnace might not have power.

Smart Thermostat

If you utilize a smart thermostat—for example one made by Nest, Ecobee, Lux, Honeywell or Bosch—troubleshooting will be determined by the model you have. Refer to the manufacturer’s website for help. If you aren’t able to get your Wi-Fi thermostat to work, contact us at 254-355-3833 for heating and cooling service.

2. Inspect Breakers and Switches

Next, confirm your breaker and furnace switch are on.

  • Find your main electrical panel. If you have no idea where it is, search for a silver metal box in your basement, garage or closet.
  • Make sure your hands and feet aren’t wet prior to using the panel or breakers.
  • Locate the breaker labeled “furnace” or “heat,” and double-check it’s moved to “on.” If you find that the breaker tripped, it will be in the middle or “off” position.
  • Moving one hand, quickly switch the breaker to the “on” position. If the breaker instantly trips and pops back to “off,” don't try to reset it and contact a professional from J & J Air Conditioning at 254-355-3833 immediately.

Regardless of your furnace’s age or brand, it has at least one ordinary wall switch positioned on or by it.

  • Ensure the switch is facing up in the “on” spot. If it was shut off, it could take your furnace up to five minutes to start. (If you’re unaware of where your furnace is located, check your basement, garage or utility closet. It could also be in a crawl space or attic.)

3. Buy a New Air Filter

When it comes to heating problems, a grungy, full air filter is often to blame.

If your filter is too dirty:

  • Your furnace won’t keep heating your home, or it may overheat from restricted airflow.
  • Your heating costs could be higher because your heat is operating more often.
  • Your heating system may fail prematurely because a filthy filter causes it to work harder.
  • Your heater can be disconnected from power if an overly clogged filter results in a tripped breaker.

Based on what make of heater you have, your air filter can be found in the interior of the blower compartment of your heating system, an attached filter case or wall-mounted return air grille.

To replace your filter:

  • Switch off your furnace.
  • Pull out the filter and angle it toward the light. If you can’t view light through it, replace it.
  • Put in the new filter with the arrow motioning toward the furnace to keep damage from happening.

Flat filters should be replaced once a month, while pleated filters should last about three months. If you have children or pets, you could have to change your filter sooner.

To make the procedure go more quickly down the line, draw with a permanent marker on your heater outside or ductwork to list the airflow direction and filter size.

4. Inspect the Condensate Pan

Commonly known as drain pans, condensate pans capture water your heating system draws from the air.

If moisture is leaking from within your heater or its pan is overflowing, follow these recommendations.

  • If your pan contains a drain (look for a PVC pipe), double-check that it’s clear. If it needs to be drained, use a special pan-cleaning tablet you can buy at home improvement or hardware retailers.
  • If your pan has a pump, inspect the float switch. If the switch is stuck “up” with liquid in the pan, call us at 254-355-3833, because you will probably have to buy a new pump.

5. Check for Heating Error Codes

If failures persist, look at your furnace’s plastic window to confirm the blower motor’s status. Depending on the type, the light might also be attached on the surface of your furnace.

If you see anything except an uninterrupted, colored light or blinking green light, reach us at 254-355-3833 for HVAC service. Your heating system could be communicating an error code that requires expert help.

6. Brush off the Flame Sensor

If your heating system makes an effort to work but shuts off without blowing heat, a dusty flame sensor might be responsible. When this occurs, your furnace will make an attempt to start three times before a safety mechanism turns it off for around an hour.

If you feel comfortable with opening up your heater, cleaning your flame sensor is a job you can do personally. Or, one of our heating service experts has the ability to complete it for you.

If you are confident cleaning the sensor personally, you should have:

  • A 1/4” hex screwdriver or wrench
  • Piece of light grit sandpaper, steel wool or emery cloth
  • An unused paper towel


  • Turn off the heating system’s power through its wall switch or breaker. If you don’t have an electric gas valve, you have to switch off the gas in addition.
  • Remove the heating system’s front panel and track the wire to the flame sensor.
  • Take off the rod and use your sandpaper, steel wool or emery cloth to gently scrub the metal rod.
  • Clear the rod with a paper towel.
  • Put the sensor back in.
  • Secure the furnace doors.
  • Turn the furnace’s power back on. It could run through a set of checks before continuing usual heating. If your furnace doesn’t ignite, the sensor may have to be replaced or something else could be creating an issue. If this takes place, contact us at 254-355-3833 for heating and cooling repair help.

7. Light the Pilot Light

If you are using an outdated heating system, the pilot light could be extinguished. To relight it, find the instructions on a sticker on your heater, or try these recommendations.

  • Look for the lever below your heater that says “pilot,” “on” and “off.”
  • Turn the switch to the “off” position.
  • Don’t do anything for at least five minutes to limit the possibility for sparking a fire.
  • Turn the knob to “pilot.”
  • Press the “reset” switch as you push the flame of a long lighter to the pilot light opening.
  • Depress the “reset” lever once the pilot light is lit.
  • If you have gone through the guide twice and the pilot light still won’t burn or remain burning, get in touch with us at 254-355-3833 for furnace service.

Check Your Energy Delivery System

Try using a second gas appliance. If it doesn’t function, your natural gas source could be shut off, or you could be out of propane.
