Its still there! That smell

It happens to us every year too. We heat with natural gas. I hate the smell of the dusty, burning smell, but do not know how to get rid of it. The dust is unreal. I get so tired of it. It is so hard to keep the house clean. Drives me nuts.

LOL, I'd guess we either get used to it, or it goes away on it's own. The only time I ever notice it is the first time we turn the furnace on in the fall. After that I don't notice it anymore. Not even when I'm standing right above a heating vent.

I know the smell you refer to because when my moms starts up her and I ma there I smell it, and often times even after like every time it kicks on. My mom Fabric freshener dryer sheets Bounce with febreeze is a good one but any will do she puts them in the vents so when it heats it gives off a better scent. I do this at times as well. You can thread it in and out of the top. Change when you no longer smell scent when it heats up.

Although a big part of your problem is being pregnant, and when women are pregnant we can smell bad smells a mile away lol, I think there are just some parts of the furnace itself that you cannot clean. It sits there, all Summer, not being used, dust collects, and sometimes ash; especially if you have a gas furnace. And when it finally gets chilly enough to turn it on, you get that musty smell. Luckily after running it a few days, the smell goes away, or you just get used to it lol.

Ah, yes the smell of the furnace being turned on for the first time of the winter season. I do not have that problem anymore. I live in a house with electric baseboard heaters.

It could be coming from your ducts. I don't know. I don't have a furnace here, we use a heat pump. Most people here don't use furnaces. Does the smell go away eventually?
