Furnace Repair Checklist

1. Look at the Thermostat

To begin, ensure your thermostat is instructing your heater to turn on.

Digital Thermostat

  • Swap out the batteries if the display is not displaying anything. If the digital monitor is mixed up, the thermostat might need to be changed.
  • Ensure the button is switched to “heat” rather than “off” or “cool.”
  • Make sure the program is set to the correct day and time and is programmed to “run.” If you’re having a hard time turning off the program, set the temperature by using the up/down arrows and holding the “hold” button. This will cause the heater to turn on if thermostat scheduling is an issue.
  • Increase the temperature setting to 5 degrees above the room temperature.

If your heating hasn’t started within a couple minutes, make certain that it has power by toggling the fan switch from “auto” to “on.” If the fan doesn’t start, your heating system may not have power.

Smart Thermostat

If you utilize a smart thermostat—for example one designed by Nest, Ecobee, Lux, Honeywell or Bosch—troubleshooting is very model-specific. Refer to the manufacturer’s website for help. If you aren’t able to get your Wi-Fi thermostat to operate, contactl us at 325-200-4667 for heating and cooling service.

2. Check Breakers and Switches

Next, you ought to confirm your breaker and furnace switch are on.

  • Look for your home’s main electrical panel. If you aren’t sure where it is, search for a gray metal box in your basement, garage or closet.
  • Make certain that your hands and feet aren’t moist in advance of opening the panel or breakers.
  • Find the breaker labeled “furnace” or “heat,” and double-check it’s turned “on.” If the breaker has tripped, it will be in the middle or “off” spot.
  • With one hand, steadily flip the breaker to the “on” location. If the breaker instantly trips and pops back to “off,” don’t try to reset it and call a team member from Abilene Air-Tech Inc at 325-200-4667 immediately.

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

  • Make certain the control is moved up in the “on” placement. If it was shut off, it could take your furnace up to five minutes to ignite. (If you’re unsure where to find your furnace, check your basement, garage or utility closet. It may also be in a crawl space or attic.)

3. Put in a New Air Filter

When we think about heating issues, a grungy, blocked air filter is frequently the top culprit.

If your filter is too grungy:

  • Your heating system won’t stay on, or it could overheat from restricted airflow.
  • Your energy expenses might be higher because your heater is working more often.
  • Your furnace could break down prematurely since a dusty filter forces it to overwork.
  • Your furnace may be disconnected from power if an extremely dirty filter results in a tripped breaker.

While it depends on what make of furnace you use, your air filter can be found inside the blower compartment of your heater, an attached filter case or wall-mounted return air grille.

To replace your filter:

  • Cut the power to your heater.
  • Pull out the filter and hold it up to the light. If you can’t notice light through it, get a new one.
  • Put in the new filter with the arrow motioning toward the heating system to prevent damage.

Flat filters ought to be replaced monthly, while pleated filters should work somewhere in the vicinity of three months. You may also get a washable filter that will work for about 10 years. If you have children or pets, you could have to put in a new filter sooner.

To make the process easier down the road, use a permanent pen on your heating system exterior or ductwork to list the airflow direction and filter size.

4. Inspect the Condensate Pan

Commonly known as drain pans, condensate pans hold moisture your heater pulls from the air.

If moisture is dripping out of your furnace or its pan is overflowing, follow these recommendations.

  • If your pan includes a drain (look for a PVC pipe), make sure that it isn’t clogged. If it requires draining, use a special pan-cleaning tablet you can get at home improvement or hardware stores.
  • If your pan uses a pump, check the float switch. If the switch is jammed “up” with standing water in the pan, contact us at 325-200-4667, because you will possibly have to buy a new pump.

5. Check for Heater Error Codes

If faults keep on happening, peek inside your heater’s plastic window to verify the blower motor’s status. Subject to the type, the light could also be attached on the exterior of your furnace.

If you note anything except a solid, colored light or blinking green light, contact us at 325-200-4667 for HVAC service. Your heating system could be giving an error code that is calling for specialized help.

6. Brush off the Flame Sensor

If your furnace tries to start but shuts off without distributing heated air, a dusty flame sensor can be at fault. When this happens, your furnace will try to turn on three times before a safety device turns it off for about an hour.

If you feel okay with opening up your furnace, cleaning your flame sensor is a job you have the ability to do on your own. Or, one of our heating service specialists can finish it for you.

If you are fine with cleaning the sensor personally, you need:

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

As the next step:

  • Disable the furnace’s power by using its wall switch or breaker. If you don’t have an electric gas valve, you will need to turn off the gas in addition.
  • Lift off the heater’s front panel and follow the wire to the flame sensor.
  • Take off the rod and use your sandpaper, steel wool or emery cloth to carefully rub the metal rod.
  • Clean the rod with a paper towel.
  • Put the sensor back in.
  • Replace the furnace doors.
  • Restore power to the furnace. It might proceed through a set of examinations before continuing usual heating. If your heating system doesn’t ignite, the sensor could have to be replaced or something else might be causing a problem. If this occurs, contact us at 325-200-4667 for heating and cooling repair assistance.

7. Reignite the Pilot Light

If you have an aging furnace, the pilot light could be out. To light it, find the instructions on a label on your furnace, or use these steps.

  • Locate the lever below your heating system labeled “pilot,” “on” and “off.”
  • Turn the switch to the “off” position.
  • Take a break for at least five minutes to limit the possibility for creating a fire.
  • Push the dial to “pilot.”
  • Press the “reset” switch as you bring the flame of a long lighter to the pilot light opening.
  • Depress the “reset” switch once the pilot light is ignited.
  • If you have gone through the instructions twice and the pilot light still won’t light or stay burning, get in touch with us at 325-200-4667 for furnace service.
