1. Examine the Thermostat
To begin, make sure your thermostat is instructing your furnace to turn on.
- Change the batteries if the monitor is empty. If the digital display is jumbled, the thermostat might need to be replaced.
- Ensure the control is on “heat” rather than “off” or “cool.”
- Make sure the program is displaying the correct day and time and is set to “run.” If you’re having problems turning off the program, regulate the temperature with the up/down arrows and pressing the “hold” button. This will cause the heating to turn on if thermostat scheduling is a problem.
- Turn the temperature setting to 5 degrees above what the room temperature currently is.
If your furnace hasn’t kicked on within a couple minutes, make certain that it has juice by changing the fan switch from “auto” to “on.” If the fan doesn’t start, your heating system might not have power.
If you use a smart thermostat—such as one manufactured by Nest, Ecobee, Lux, Honeywell or Bosch—troubleshooting is very model-specific. Check the manufacturer’s website for assistance. If you’re still unable to get your Wi-Fi thermostat to work, contactl us at 239-244-3439 for heating and cooling service.
2. Examine Breakers and Switches
Next, you ought to verify your breaker and furnace switch are on.
- Find your residence’s main electrical panel. If you have no idea where it is, keep an eye out for a metallic metal box in your basement, garage or closet.
- Make certain that your hands and feet are dry in advance of using the panel or breakers.
- Locate the breaker labeled “furnace” or “heat,” and make sure it’s moved to “on.” If you find that the breaker tripped, it will be in the middle or “off” spot.
- Moving one hand, steadily switch the breaker to the “on” position. If the breaker immediately trips and pops back to “off,” leave it alone and contact an expert from Speedy Air Conditioning at 239-244-3439 immediately.
It doesn’t matter how old your furnace is or what brand it is, it has no less than one regular wall switch placed on or close to it.
- Make certain the switch is moved up in the “on” placement. If it was switched off, anticipate your furnace could take up to five minutes to ignite. (If you’re unaware of where your furnace is located, take a look at your basement, garage or utility closet. It may also be in a crawl space or attic.)
3. Replace the Air Filter
When we think about heating problems, a dirty, clogged air filter is frequently the top offender.
If your filter is too dusty:
- Your heating system won’t keep heating your home, or it might overheat from reduced airflow.
- Your gas bills could go up because your heater is running too often.
- Your furnace could break down too soon due to the fact a dirty filter triggers it to overwork.
- Your furnace might be cut off from power if an extremely dirty filter is the cause of a tripped breaker.
While it depends on what model of heating system you use, your air filter can be found inside the blower compartment of your furnace, an attached filter case or wall-mounted return air grille.
To replace your filter:
- Turn off your heater.
- Pull out the filter and hold it up to the light. If you can’t view light through it, use a new one.
- Install the new filter with the arrow motioning toward the heating system to prevent damage.
Flat filters need to be replaced monthly, while pleated filters should last around three months. You could also buy a washable filter that will work for about 10 years. If you have children or pets, you might have to change your filter sooner.
To make the process easier down the road, use a permanent marker on your heating system outside or ductwork to indicate the airflow direction and filter size.
4. Look at the Condensate Pan
Also known as drain pans, condensate pans capture water your furnace pulls from the air.
If liquid is dripping from within your heater or its pan has too much water in it, use these guidelines.
- If your pan includes a drain (look for a PVC pipe), double-check that it isn’t clogged. If it requires draining, use a special pan-cleaning tablet you can buy at home improvement or hardware shops.
- If your pan has a pump, take a look at the float switch. If the button is jammed “up” with liquid in the pan, contact us at 239-244-3439, because you will probably have to install a new pump.
5. Watch for Heater Error Codes
If failures keep on happening, take a look within your heater’s plastic window to verify the blower motor’s status. Depending on the brand, the light could also be fixed on the surface of your furnace.
If you note anything else besides a steady, colored light or twinkling green light, call us at 239-244-3439 for HVAC service. Your furnace may be giving an error code that needs specialized help.
6. Clean the Flame Sensor
If your heater attempts to work but switches off without blowing heat, a dirty flame sensor could be responsible. When this occurs, your heater will make an attempt to start three times before a safety mechanism turns it off for around an hour.
If you feel comfortable with taking the panels off your furnace, cleaning your flame sensor is a task you have the ability to do personally. Or, one of our heating service specialists is able to do it for you.
If you want to clean the sensor yourself, you need:
- A 1/4” hex screwdriver or wrench
- Bit of light grit sandpaper, steel wool or emery cloth
- A dry, clean paper towel
As the next step:
- Turn off the furnace’s power through its wall switch or breaker. If your gas valve isn’t electric, you have to shut off the gas in addition.
- Remove the furnace’s front panel and track the wire to the flame sensor.
- Unscrew the rod and use your sandpaper, steel wool or emery cloth to lightly rub the metal rod.
- Clean the rod with a paper towel.
- Remount the sensor.
- Replace the furnace doors.
- Restore power to the furnace. It may go through a sequence of checks before resuming usual operation. If your furnace doesn’t ignite, the sensor might need to be replaced or something else may be causing a problem. If this occurs, contact us at 239-244-3439 for heating and cooling repair support.
7. Reignite the Pilot Light
If you have an outdated heating system, the pilot light could be out. To light it, locate the guide on a sticker on your furnace, or try these guidelines.
- Look for the switch beneath your furnace that says “pilot,” “on” and “off.”
- Push the switch to the “off” position.
- Take a break for at least five minutes to limit the possibility for sparking a fire.
- Push the switch to “pilot.”
- Push the “reset” switch as you push the flame of a long lighter to the pilot light opening.
- Depress the “reset” switch once the pilot light is burning.
If you have used the guide twice and the pilot light still won’t light or keep burning, get in touch with us at 239-244-3439 for furnace service.
Double-Check Your Energy Delivery System
Try using another gas appliance. If it doesn’t function, your natural gas source might be shut off, or you might have run out of propane.
