maple syrup smell

could be a coolant leak

it's not a coolant leak the refrigerant has no smell and the oil would stink but it would smell like oil
so lets see do you have forced air gas or electric do you smell it when the heat come's on or all the time if you only smell it when the heat come on start checking your vents that is if there not on the ceiling or check the return good luck

Do you or your children eat maple and brown sugar flavored oatmeal? Is it heated in the microwave? My daughter loves that stuff and will eat it day and night. When she does, my house stinks of the stuff and gives me a headache. The microwaves exhaust the smell and the air intake for the AC pushes the smell through the vents.

grabbed some planks of old wood neighbor was throwing out,building is 90yrs old,clearing out basement,but wood smells like maple syrup,is it ok to cleanup and use?probally from ceiling in basement.Thank you so much

My house is brand new, well as of one year. In the back bedroom it has a odd smell of maple syrup. A new bed hardly been used and a tv. That's all that's in that room. It's a spare room. Carpet. Blinds. Nothing else. I can't pin point where the smells coming from.

Did you ever find the solution. I’m facing the same thing.

It’s the tape they used to seal up the furnace.

Who did you contact to find that out?

I thought the smell at my house was a house plant. its driving me crazy to figure this out.

I have the same problem with this oily , maple smell, took out all air fresheners and changed fabric softener,still this smell just won’t go away.
I’m going to talk to the AC company that installed a air conditioner about three years ago.In my corner of the bedroom the smell is all Day and night.
Can’t get a breath of fresh air while in bed.

I have a portable Haier air conditioner, we have been using it for about 2 years and all at once it started smelling like maple syrup coming from the vent. I took it outside, took it apart cleaned everything and bleached the bottom of pan. It still smells like maple syrup. The type of Freon is R410A some say it a leak. I have let this machine run for hours . It is still blowing cold air.
My question is have you ever seen this happen before.

My sickly maple syrup smell is nearly constant now, not connected to when the natural gas furnace goes on. The answers online do not seem to address the issue. Calling the HVAC tech for another $$ home visit seems to be the only recourse. It began after the annual maintenance -service -this past fall. NOT the prior year or two with the new furnace and natural gas.

Hi all- I Am experiencing the same thing now! Did hvac people figure it out?!

No, they laughed, charged nearly $100, couldn't smell anything b/c their clothing reeked of fuel oil, but guessed it must be "spilled chemicals!" They said to open windows & air out house when weather gets warm enough. That's NOT a solution, would be temporary. It is awful. from BV018901,

I just read an artilcle that said fenugreek (the leaves, spice, and tea) could cause the smell. I've been having the same issue, since getting a brand new GE air conditioner. After reading that article, I realized that my roomate had been consuming fenugreek. I believe there is some growing in the neighbors garden (I'm not a botanist LOL).
