1. Look at the Thermostat

First, make certain that your thermostat is instructing your heat to start.

Digital Thermostat

  • Swap out the batteries if the screen is blank. If the digital monitor is mixed up, the thermostat could need to be swapped out.
  • Ensure the button is switched to “heat” rather than “off” or “cool.”
  • Make certain the program is showing the appropriate day and time and is set to “run.” If you’re having trouble getting out of the program, regulate the temperature by using the up/down arrows and holding the “hold” button. This will make the furnace to start if thermostat settings are an issue.
  • Turn the temperature setting to 5 degrees hotter than what the room temperature currently is.

If your heat hasn’t turned on within a couple minutes, make sure it has electricity by changing the fan switch from “auto” to “on.” If the fan doesn’t begin to run, your heating system may not have power.

Smart Thermostat

If you use a smart thermostat—like one manufactured by Nest, Ecobee, Lux, Honeywell or Bosch—troubleshooting will depend on your model. Refer to the manufacturer’s website for assistance. If you aren’t able to get your Wi-Fi thermostat to function, reachl us at 727-369-6195 for heating and cooling service.

2. Examine Breakers and Switches

Next, you should check if your breaker and furnace switch are on.

  • Find your residence’s 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 moist in advance of touching the panel or breakers.
  • Look for the breaker labeled “furnace” or “heat,” and ensure it’s switched “on.” If you discover a tripped breaker, it will be in the middle or “off” area.
  • Using one hand, quickly flip the breaker to the “on” spot. If the breaker trips right away and pops back to “off,” don’t touch it and get in touch with a professional from Hale's Air Conditioning Services Inc at 727-369-6195 immediately.

No matter your furnace’s age or brand, it has at least one ordinary wall switch located on or near it.

  • Ensure the control is facing up in the “on” placement. If it was turned off, anticipate your furnace could take up to five minutes to start. (If you’re unsure where to locate your furnace, check your basement, garage or utility closet. It may also be in a crawl space or attic.)

3. Buy a New Air Filter

When it comes to heating breakdowns, a grungy, clogged air filter is frequently the top offender.

If your filter is too dirty:

  • Your heater won’t stay on, or it may get too hot from limited airflow.
  • Your utility costs may go up because your heating system is operating more than it should.
  • Your furnace could fail prematurely due to the fact a filthy filter triggers it to work harder.
  • Your heating may be disconnected from power if an overly filthy filter causes the breaker to trip.

Based on what type of heater you own, your air filter is located in the interior of the blower compartment of your furnace, an attached filter case or wall-mounted return air grille.

To put in a new filter:

  • Turn off your heating system.
  • Pull out the filter and angle it toward the light. If you can’t see light through it, get a new one.
  • Put in the new filter with the arrow facing toward the heating system to keep damage from happening.

Flat filters should be replaced monthly, while pleated filters should last somewhere in the vicinity of three months. You could 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 smoother in the future, use a permanent marker on your heater housing or ductwork to indicate the airflow direction and filter size.

4. Check the Condensate Pan

Also known as drain pans, condensate pans hold moisture your furnace pulls from the air.

If water is dripping out of your furnace or its pan has too much water in it, try these steps.

  • If your pan contains a drain (look for a PVC pipe), double-check that it isn’t clogged. If it should be drained, get a special pan-cleaning tablet you can get at home improvement or hardware shops.
  • If your pan has a pump, inspect the float switch. If the lever is jammed “up” with water in the pan, reach us at 727-369-6195, because you will probably have to install a new pump.
error codes icon

5. Look for Heating Error Codes

If faults continue, peek inside your furnace’s plastic window to confirm the blower motor’s status. Depending on the model, the light might also be attached on the exterior of your heater.

If you note anything except a steady, colored light or blinking green light, call us at 727-369-6195 for HVAC service. Your heater might be communicating an error code that is calling for expert help.

6. Scrub the Flame Sensor

If your heating system tries to run but shuts off without putting out heat, a dusty flame sensor might be at fault. When this takes place, your heater will make an attempt to start three times before a safety device shuts it down for approximately an hour.

If you feel comfortable with opening up your furnace, gently scrubbing your flame sensor is work you are able to do yourself. Or, one of our heating service experts has the ability to do it for you.

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

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

As the next step:

  • Turn off the heater’s power through its wall switch or breaker. If you don’t have an electric gas valve, you have to turn off the gas along with it.
  • Remove the heating system’s front panel and follow the wire to the flame sensor.
  • Remove the rod and use your sandpaper, steel wool or emery cloth to lightly rub the metal rod.
  • Clean the rod with a paper towel.
  • Screw the sensor back in.
  • Replace the furnace doors.
  • Switch the furnace’s power back on. It might proceed through a sequence of examinations before continuing usual running. If your heater doesn’t start, the sensor could need to be replaced or something else might be causing a problem. If this happens, get in touch with us at 727-369-6195 for heating and cooling repair support.

7. Light the Pilot Light

If you own an older heater, the pilot light could be extinguished. To light it, look for the guide on a sticker on your heating system, or follow these recommendations.

  • Locate the toggle below your heater that says “pilot,” “on” and “off.”
  • Move the switch to the “off” position.
  • Don’t do anything for at least five minutes to prevent creating a fire.
  • Push the dial to “pilot.”
  • Press the “reset” button as you move the flame of a long lighter to the pilot light opening.
  • Depress the “reset” button once the pilot light is ignited.
  • If you have tried the list twice and the pilot light still won’t ignite or keep ignited, get in touch with us at 727-369-6195 for furnace service.

Check Your Fuel Supply

Try using an additional gas appliance. If it doesn’t work, your natural gas service might be switched off, or you could be out of propane.
