Last night we turned our 1 year old a/c system on for the first time this year. It felt great and we slept great. Today we were out all day at a memorial day picnic. We came home about 6pm and when we came in the house there was a distinctly abnormal smell. It's almost like a solvent or some cheap pvc product like an air mattress or pool. It's not real strong but definitely noticeable. The house is cool and the unit is blowing cool air. Any chance this is a refrigerant leak in the coil? Or is it most likely something we drug in the house that we aren't thinking would give of a smell?
TIA, Mark
