1. Inspect the Thermostat
To start, ensure your thermostat is telling your heater to turn on.
- Replace the batteries if the monitor is blank. If the digital monitor is messed up, the thermostat may need to be changed.
- Ensure the control is on “heat” as opposed to “off” or “cool.”
- Ensure the program is set to the right day and time and is set to “run.” If you’re having trouble getting out of the setting, set the temperature by utilizing the up/down arrows and using the “hold” button. This will cause the heater to start if thermostat scheduling is a problem.
- Set the temperature setting to 5 degrees warmer than the temperature of the room.
If your heater hasn’t kicked on within several minutes, ensure it has juice by switching the fan switch from “auto” to “on.” If the fan doesn’t operate, your furnace may not have power.
If you have a smart thermostat—for example one made by Nest, Ecobee, Lux, Honeywell or Bosch—troubleshooting is very model-specific. Refer to the manufacturer’s website for support. If you’re still unable to get your Wi-Fi thermostat to operate, contactl us at 561-270-6228 for heating and cooling service.
2. Check Breakers and Switches
Next, you will need to verify your breaker and furnace switch are on.
- Locate your residence’s main electrical panel. If you have no idea where it is, search for a gray metal box in your basement, garage or closet.
- Ensure your hands and feet aren’t moist before touching the panel or breakers.
- Find the breaker marked “furnace” or “heat,” and make sure it’s switched “on.” If you find that the breaker tripped, it will be in the middle or “off” position.
- With one hand, firmly flip 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 team member from A2Z Air Inc at 561-270-6228 right away.
No matter your furnace’s age or brand, it has no less than one ordinary wall switch set on or by it.
- Make sure the control is flipped up in the “on” position. If it was shut off, anticipate your furnace could take up to five minutes to ignite. (If you’re unsure where to locate your furnace, look in your basement, garage or utility closet. It might also be in a crawl space or attic.)
3. Get a New Air Filter
When we think about furnace issues, a filthy, full air filter is frequently to blame.
If your filter is too grungy:
- Your heater won’t be able to stay on, or it could get too warm from restricted airflow.
- Your utility costs may go up because your heating system is running too often.
- Your heater may fail prematurely since a filthy filter forces it to work overtime.
- Your heating system can be disconnected from power if an overly clogged filter causes the breaker to trip.
Depending on what model of heater you own, your air filter will be inside the blower compartment of your furnace, an attached filter case or wall-mounted return air grille.
To swap out your filter:
- Turn off your furnace.
- Take out the filter and hold it up to the light. If you can’t see light through it, replace it.
- Put in the new filter with the arrow facing toward the furnace to prevent damage.
Flat filters ought to be replaced every month, while pleated filters should be used for around three months. You can also get a washable filter that will work for about 10 years. If you have children or pets, you may have to change your filter sooner.
To make changing your filter go more quickly in the future, write with a permanent pen on your heater outside or ductwork to list the airflow direction and filter size.
4. Examine the Condensate Pan
Commonly known as drain pans, condensate pans capture water your furnace removes from the air.
If water is leaking from within your heating system or its pan has too much water in it, try these recommendations.
- If your pan has a drain (look for a PVC pipe), make sure that it’s clear. If it needs to be drained, get a special pan-cleaning tablet you can purchase at home improvement or hardware shops.
- If your pan contains a pump, take a look at the float switch. If the button is stuck “up” with water in the pan, call us at 561-270-6228, because you will probably have to install a new pump.
5. Check for Heater Error Codes
If faults keep on happening, look inside your furnace’s plastic window to confirm the blower motor’s status. Depending on the brand, the light may also be fixed on the surface of your heating system.
If you see anything else besides a steady, colored light or blinking green light, call us at 561-270-6228 for HVAC service. Your heating system may be emitting an error code that requires specialized assistance.
6. Clean the Flame Sensor
If your heating system tries to operate but turns off without distributing heated air, a grimy flame sensor might be at fault. When this happens, your furnace will attempt to start three times before a safety device turns it off for approximately an hour.
If you feel comfortable with opening up your heater, gently scrubbing your flame sensor is work you have the ability to do personally. Or, one of our heating service specialists can finish it for you.
If you are confident cleaning the sensor personally, you should have:
- A 1/4” hex screwdriver or wrench
- Portion of light grit sandpaper, steel wool or emery cloth
- A dry, clean paper towel
- Disable the heater’s power through its wall switch or breaker. If you don’t have an electric gas valve, you will need to shut off the gas as well.
- Take off the furnace’s front panel and follow the wire to the flame sensor.
- Unscrew the rod and use your sandpaper, steel wool or emery cloth to lightly clean the metal rod.
- Wipe off the rod with a paper towel.
- Put the sensor back in.
- Put the furnace doors back on.
- Turn the furnace’s power back on. It might go through a set of examinations before resuming regular heating. If your heater doesn’t turn on, the sensor might require replacement or something else might be creating an issue. If this takes place, get in touch with us at 561-270-6228 for heating and cooling repair help.
7. Light the Pilot Light
If you have an outdated heater, the pilot light could be extinguished. To relight it, locate the steps on a sticker on your heating system, or follow these guidelines.
- Find the switch below your furnace labeled “pilot,” “on” and “off.”
- Move the switch to the “off” position.
- Wait at least five minutes to prevent starting a fire.
- Push the switch to “pilot.”
- Press the “reset” switch as you push the flame of a long lighter to the pilot light opening.
- Release the “reset” lever once the pilot light is lit.
If you have gone through the instructions twice and the pilot light still won’t ignite or remain lit, call us at 561-270-6228 for furnace service.
Double-Check Your Energy Source
Try switching on an additional gas appliance. If it doesn’t work, your natural gas source could be switched off, or you may have run out of propane.
