Customer Question

I have a burning smell (the odor you can get the first couple times your furnace runs each year) but it is only located in 2 rooms. Both rooms are located on the same wall of house. Does this sound normal or should I have someone look at it?

Hello,

Dust accumulates on the furnace heat exchanger and burns off the first time the furnace fires in the fall, that is a common problem. That generally only happens once a year however.

Let me know if that rings any bells on your end or not, we can go from there without any time limit,

If you do not get the smell in the rest of the house, it is possible that a bad wire connection is over heating in the wall, at one of the junction boxes, It is unlikely however that would be occurring intermittently though, however if it IS actually occurring, it is a *dangerous condition,

It has been persistent for the past couple hours, not in rest of home. Did not dissipate the smell after ventilating the room

I have called an electrician and am waiting on them to get here but just not sure if it is even an electrical issue 😐
Expert:  Phil replied 1 year ago.

There is a high probability that is an electrical issue, You should unplug all of the appliances in the rooms and turn off the lights, it the smell abates you are relatively safe, if the smell does not abate it could very easily be a dangerous electrical short condition

In that case, turn on the lights in the rooms, and plug in a vacuum cleaner or lamp, then go to the house main breaker box and turn off breakers until you loose power to the rooms in question, and leave that breaker or breakers OFF,

If the smell abates you are most likely very safe, if not, it IS an emergency,

In that case you might want to turn off the main breaker at the top of the house breaker panel.
