Furnace Repair in Tucker, GA

1. Look at the Thermostat

First, ensure your thermostat is telling your heater to turn on.

Digital Thermostat

• Change the batteries if the monitor is empty. If the digital screen is mixed up, the thermostat may need to be swapped out.
• Make sure the button is switched to “heat” rather than “off” or “cool.”
• Ensure the program is showing the right day and time and is scheduled to “run.” If you’re having a hard time turning off the setting, regulate the temperature by using the up/down arrows and pressing the “hold” button. This will cause the furnace to start if thermostat is causing a problem.
• Set the temperature setting to 5 degrees above what the room temperature currently is.

If your heater hasn’t started within a few minutes, make sure it has power by switching the fan switch from “auto” to “on.” If the fan doesn’t begin to run, your heating system could be without power.

Smart Thermostat

If you utilize a smart thermostat—like one designed by Nest, Ecobee, Lux, Honeywell or Bosch—troubleshooting will depend on your model. Refer to the manufacturer’s website for help. If you still can’t get your Wi-Fi thermostat to operate, contact us at 770-450-1539 for heating and cooling service.

2. Examine Breakers and Switches

Next, confirm your breaker and furnace switch are on.

• Find your main electrical panel. If you aren’t sure where it is, keep an eye out for a gray metal box in your basement, garage or closet.
• Make certain that your hands and feet are dry prior to using the panel or breakers.
• Look for the breaker marked “furnace” or “heat,” and ensure it’s switched “on.” If the breaker has tripped, it will be in the middle or “off” area.
• With one hand, steadily turn the breaker to the “on” position. If the breaker immediately trips and pops back to “off,” don't try to reset it and get in touch with an expert from ACS Heating and Air Conditioning at 770-450-1539 right away.

Regardless of your furnace’s age or brand, it has no less than one ordinary wall switch set on or close to it.

• Ensure the lever is moved up in the “on” position. If it was shut off, anticipate your furnace could take up to five minutes to turn on. (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. Replace the Air Filter

When we think about heating breakdowns, a grungy, clogged air filter is often the top offender.

If your filter is too dusty:

• Your heat won’t keep heating your home, or it may get too warm from reduced airflow.
• Your utility bills may be higher because your furnace is operating too often.
• Your heater could fail prematurely due to the fact a dirty filter forces it to work harder.
• Your heater might be disconnected from power if an overly clogged filter causes the breaker to trip.

Based on what make of furnace you use, your air filter is located inside the blower compartment of your heater, an attached filter case or wall-mounted return air grille.

To replace your filter:

• Turn off your heater.
• Take out the filter and tilt it toward the light. If you can’t see light through it, get a new one.
• Put in the new filter with the arrow pointing toward the heater to avoid damage.

Flat filters ought to be replaced once a month, while pleated filters should last about three months. If you have children or pets, you may have to put in a new filter sooner.

To make changing your filter smoother down the road, use a permanent marker on your furnace housing or ductwork to show the airflow direction and filter size.

4. Examine the Condensate Pan

Also known as drain pans, condensate pans hold liquid your furnace removes from the air.

If moisture is dripping from your furnace or its pan has too much water in it, follow these recommendations.

• If your pan has a drain (look for a PVC pipe), check that it isn’t clogged. If it should be drained, drop in a special pan-cleaning tablet you can buy at home improvement or hardware retailers.
• If your pan uses a pump, take a look at the float switch. If the switch is stuck “up” with liquid in the pan, reach us at 770-450-1539, because you will likely have to get a new pump.

5. Check for Heater Error Codes

If failures continue, look within your heater’s plastic window to check the blower motor’s status. Dependent on the type, the light may also be fixed on the outside of your heating system.

If you notice anything else besides an uninterrupted, colored light or blinking green light, contact us at 770-450-1539 for HVAC service. Your heater might be communicating an error code that requires specialized assistance.

6. Clean the Flame Sensor

If your heater makes an effort to operate but shuts off without distributing warm air, a filthy flame sensor might be responsible. When this takes place, your furnace will make an attempt to turn on three times before a safety device shuts it down for about an hour.

If you feel confident with taking the panels off your heating system, gently scrubbing your flame sensor is a job you have the ability to do yourself. Or, one of our heating service professionals is able to do it for you.

If you want to clean the sensor personally, you need:

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

Next:

• Turn off the heating system’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 along with it.
• Take off the furnace’s front panel and trace the wire to the flame sensor.
• Take off 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.
• Put the furnace doors back on.
• Switch the furnace’s power back on. It might go through a sequence of examinations before proceeding with regular running. If your heating system doesn’t start, the sensor might need to be replaced or something else might be wrong. If this takes place, contact us at 770-450-1539 for heating and cooling repair help.

7. Light the Pilot Light

If you are using an aging furnace, the pilot light could be turned off. To reignite it, find the steps on a sticker on your heater, or use these guidelines.

• Find the toggle on the bottom of your heater that says “pilot,” “on” and “off.”
• Move the switch to the “off” position.
• Take a break for at least five minutes to limit the possibility for sparking a fire.
• Push the dial to “pilot.”
• Push the “reset” button as you push the flame of a long lighter to the pilot light opening.
• Depress the “reset” switch once the pilot light is lit.

If you have used the guide twice and the pilot light still won’t ignite or stay burning, contact us at 770-450-1539 for furnace service.

Inspect Your Gas Source

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