Last fall I painted one room in a small apartment with oil based primer. When I bought the primer, the very experienced paint guy told me not to run the furnace because it would take a long time to get the oil primer smell out of the hvac system. By the time I got around to actualling putting the primer on the temperature outside had dropped into the low 30's and I was pretty much forced to run the furnace during the painting process and after. It is now at least 4 months later and I can still smell an odor coming from the ducts. There was no odor there prior to the painting so I am assuming paint is the cause. I have painted with latex while the furnace was runnining the past and not had an issue but this is my first time using an oil based primer indoors. If you just let the fan run there is no odor at all...it only happens when the burners are on. The odor can be smelled primarily after the heat exchanger.
Has anyone ever heard of this issue and any way to minimize the odor?
Thanks in advance for your replies.
