Furnace Repair in Carson City, NV

First, make sure your thermostat is instructing your furnace to turn on.

Replace the batteries if the screen is blank. If the digital screen is jumbled, the thermostat may need to be replaced.

Make sure the switch is set to “heat” instead of “off” or “cool.”

Ensure the program is set to the correct day and time and is set to “run.” If you’re having problems overriding the program, set the temperature by using the up/down arrows and press the “hold” button. This will cause the furnace to turn on if thermostat programming is causing a problem.

Increase the temperature setting to 5 degrees warmer than the room temperature.

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

If you have a smart thermostat—like one made by Nest, Ecobee, Lux, Honeywell or Bosch—troubleshooting is very model-specific. Check the manufacturer’s website for help. If you still can’t get your Wi-Fi thermostat to work, call us at 775-230-7628 for heating and cooling service.

Next, you will need to check if your breaker and furnace switch are on.

Look for your house’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 sure your hands and feet are dry before touching the panel or breakers.

Locate the breaker labeled “furnace” or “heat,” and make sure it’s switched “on.” If the breaker has tripped, it will be in the middle or “off” position.

Using one hand, firmly switch the breaker to the “on” position. If the breaker immediately trips and pops back to “off,” leave it alone and contact a professional from Anderson Heating & A/C at 775-230-7628 right away.

It doesn’t matter how old your furnace is or what brand it is, it has at least one standard wall switch located on or close to it.

Make sure the switch is flipped up in the “on” position. If it was turned off, anticipate your furnace could take up to five minutes to ignite. (If you don’t know where to find your furnace, look in your basement, garage or utility closet. It could also be in a crawl space or attic.)

When it comes to furnace problems, a dirty, clogged air filter is often the top culprit.

If your filter is too dirty:

• Your furnace won’t be able to stay on, or it could overheat from restricted airflow.
• Your energy bills could increase because your furnace is turning on too often.
• Your furnace could fail sooner than it should because a dirty filter causes it to work harder.
• Your furnace can be disconnected from power if an excessively dirty filter causes the breaker to trip.

Depending on what model of furnace you own, 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:

1. Turn off your furnace.
2. Remove the filter and hold it up to the light. If you can’t see light through it, get a new one.
3. Add the new filter with the arrow pointing toward the furnace to avoid damage.

Flat filters should be replaced every month, while pleated filters should last about three months. You can also get a washable filter that will last about 10 years. If you have children or pets, you may have to put in a new filter more frequently.

To make the process go more quickly in the future, use a permanent marker on your furnace housing or ductwork to show the airflow direction and filter size.

Otherwise known as drain pans, condensate pans catch water your furnace removes from the air.

If water is leaking out of your furnace or its pan has standing water in it, follow these steps.

• If your pan has a drain (look for a PVC pipe), check that it isn’t full. If it needs to be drained, use a special pan-cleaning tablet you can purchase at home improvement or hardware stores.
• If your pan has a pump, inspect the float switch. If the switch is stuck “up” with water in the pan, contact us at 775-230-7628, because you will likely need a new pump.

If malfunctions continue, peek inside your furnace’s plastic window to verify the status of the blower motor. Depending on the model, the light could also be mounted on the outside of your furnace.

If you see anything except a steady, colored light or blinking green light, call us at 775-230-7628 for HVAC service. Your furnace may be emitting an error code that requires professional help.

If your furnace tries to start but turns off without putting out heat, a dirty flame sensor could be to blame. When this occurs, your furnace will try to ignite three times before a safety feature turns it off for about an hour.

If you feel comfortable with opening up your furnace, cleaning your flame sensor is something you can do yourself. Or, one of our heating service experts can do it for you.

If you want to clean the sensor yourself, you’ll need:

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

Next:

• Disable the furnace’s power by using its wall switch or breaker. If your gas valve is not electric, you will need to shut off the gas as well.
• Lift off 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 gently rub the metal rod.
• Wipe off the rod with a paper towel.
• Remount the sensor.
• Replace the furnace doors.
• Turn the furnace’s power back on. It could go through a series of checks before continuing normal operation. If your furnace doesn’t turn on, the sensor may need to be replaced or something else may be wrong. If this happens, get in touch with us at 775-230-7628 for heating and cooling repair assistance.

If you own an older furnace, the pilot light could be turned off. To relight it, find the instructions on a label on your furnace, or follow these steps.

• Look for the switch on the bottom of your furnace labeled “pilot,” “on” and “off.”
• Turn the switch to the “off” position.
• Wait at least five minutes to avoid possibly starting a fire.
• Turn the knob to “pilot.”
• Hold down the “reset” button as you bring the flame of a long lighter to the pilot light opening.
• Release the “reset” button once the pilot light is lit.

If you have followed the instructions twice and the pilot light still won’t light or stay lit, contact us at 775-230-7628 for furnace service.

Try switching on another gas appliance. If it doesn’t work, your natural gas service could be turned off, or you could be out of propane.
