It's a frigid winter day and you awaken to a cold house. You quickly discover that the heating unit isn't working! Your first idea is to require emergency situation furnace repair work.
Before you get your phone, you can take a couple of easy steps to see if you may be able to fix the problem by yourself. This might assist fix the problem quicker and without the expenditure of a possibly unnecessary emergency situation heater repair work call.
1. Check your thermostat.
- Ensure that the thermostat is on and set to "heat." This sounds apparent, but you would not think how many service calls happen due to the fact that the house owner didn't understand that someone (like a visitor or child) adjusted the settings!
- If your thermostat has a fan setting, set it to "vehicle" rather of "on." Otherwise, the fan might blow continuously even when the air isn't being heated up.
- If the room temperature is lower than the thermostat setting, attempt changing the setting up a few degrees to see if the heating system starts.
2. Make certain you have power to the heating system.
Even if you have a gas furnace, an interruption in electric power will interrupt your heating system from producing heat. You might have a breaker that has tripped.
If that holds true, you can reset it by air duct cleaning turning the circuit all the way off and after that on again. If the circuit right away breaks once again, call an expert.
3. Inspect your air filter.
An air filter that is extremely blocked will not permit the air to be warmed properly. It might trigger your furnace to overheat and shut down.
Get rid of the filter and hold it against the light. Can't see any light through it? Replace http://query.nytimes.com/search/sitesearch/?action=click&contentCollection®ion=TopBar&WT.nav=searchWidget&module=SearchSubmit&pgtype=Homepage#/hvac it. We advise inspecting your heating system filter every month and replacing as needed.
4. If you have a gas heating system, make sure the gas supply is on.
If you've had actually any repair work done lately, someone may have turned off the gas supply valve and after that forgot to turn it back on. Or, the gas company may have shut down the gas lines for upkeep. A fast check with the gas company is a good idea if you think this might be the case.
- Examine the gas valve at the gas company's meter.
- Check the gas valve on your heater. Your heating system's gas valve is on when the deal with is inline (parallel) with the pipeline. If it's off, the manage will be perpendicular to the pipe.
If you smell gas, turn off the supply and instantly call a professional.
5. Inspect the ignition source or pilot light.
A lot of contemporary furnaces have actually an igniter paired with a flame sensing unit rather than a physical pilot light. Both of these can wear out and require repair work. In reality, ignitor and flame sensor issues are some of the most common furnace repairs we come across.
If you have an older furnace, your unit may have a physical pilot burner. A draft or disturbance in gas service can trigger the pilot burner to go out. If your pilot burner is out, and you've already validated that you have a safe gas supply, attempt relighting it according to your owner's manual. (This is normally finished with a fireplace match or long barbeque-style lighter.).
If you're not comfortable with this, or the pilot light won't stay lit, call a technician.
