Here are simple furnace fixes you wish you knew earlier.


A furnace can be daunting—especially when nothing is working. Howbeit, we brought you good news from furnace repair professionals. If you carry out simple fixes that cost nearly nothing, close to 1/4 of all service calls could be avoided.

Before you presume that you have a problem with the furnace,  check out the thermostat to ensure that it is telling the furnace to come on in all actuality.

Thermostats, particularly programmable ones, can get to be very complex, and the more the options of a thermostat, the more that can be wrong.

Ensure that the switch is on “Heat” not on on “Cool.”

Examine the setting of the temperature.

Compare the setting of the temperature to the temperature of the room. Adjust the temperature setting to be five degrees more than the room temperature and observe if the furnace kicks on.

Ensure the program is showing the correct day and time, check the a.m. and p.m. settings as well.

Now, Trace the wires of the thermostat back to the furnace, checking for breaks.

This is mostly done if you have carried out any form of remodeling in the recent time. If you notice any break in any of the slim wires, tie the line together once again and enwrap it using electrical tape.

Put the battery back. If you have a power failure due to a weak battery, you will lose completely, your settings, while the thermostat reverts to the default program.

Open the thermostat while you blow gently, any form of dust or debris. Ensure that its plane and attached firmly to the wall. Make sure also, that none of the wires coming into the thermostat are loosened.

It sounds incredible, but furnace professionals always discover that most times, the sole “repair” a furnace desire is to be switched on. Find a wall switch that is standard on/near the furnace—every furnace, no matter how old or what type it is, has one somewhere. Examine the furnace’s fuse or circuit breaker.  Ensure that the panel in the front, which covers the motor blower is fastened securely—there is always a  push-in switch that lies beneath it that must stay depressed completely for the furnace to function.


Dirty filters are the commonest causal agent of problems associated with the furnace. Dust and dirt restrain airflow, and if the filter becomes too clogged up, the heat exchanger will become overheated and shut down very quickly making your house not to warm up. If the blower runs but produces no heat, then you have to have the filter replaced. When a filter is dirty, it also makes soot to gradually build up on the heat exchanger, thereby reducing the efficaciousness of the furnace and reducing its lifespan as well.

The owner’s manual displays where the filter is located and how to take it off. Do not let those inexpensive flat filters stay up to a month. Change them every one month! Ensure that the arrow is pointing to the furnace. Scrutinize pleated filters one time in a month. Hold them close to a source of light and if you can not clearly see the light through them, change them.

Furnace producers say that pleated filters are functional for up to three months, but you have to replace them more frequently if you own pets and kids or if you generate a lot of dust.


Always remember to turn the shutoff switch off (look at Solution 2) and before you change the filter or while working on the thermostat or the furnace, turn off the thermostat.


Just as it is with switches, someone, perhaps, may turn off a gas valve and forgot to turn it on. You have to follow the gas line back, from the furnace to the meter, and once you sight a handle that is vertical to the gas valve, turn it, so it becomes parallel. If you own a boiler or an old furnace, you may have as well a pilot light. Unmount the front panel and the burner cover and scrutinize it to ensure that it is lit.


Due to the warmth, birds some of the times, fall into the furnace chimney exhaust flue. Turn off the furnace; turn off the thermostat fully down, then disassemble the duct where the furnace is being exited and examine for debris. Do not forget to reassemble the parts in the same order and direction that you used in dismantling them
