I have been smelling an oil smell throughout the entire house for a little while now especially when I leave and I return. We live in Florida and have a new central air conditioning that use R 410 (and it also has some sort of label that says POE oil). The rest of the house is completely electric and have no gas in the home. No furnace etc.

We called the air conditioner installer but he doesn't think the smell could be coming from the AC. The AC is in the garage but there is no smell in the garage and particularly not similar at all to the smell in the house. The reading on our Carbon monoxide detector reads 0. What could this smell be and if not the AC what could it possibly be?

Thanks so much!

Its not the ac... 410 a does not smell. It has to be something else.

Thanks. I really wonder what this is then. I seem to be getting headaches only when I get home at night. I'm also pregnant so I'd love to figure what this is and hoping it's nothing serious. It's so odd because the smell is pretty equally distributed throughout the home.
