I do not believe there is any legal recourse... One thing I can share with you, so that you can help yourself (if you decide to stay) When you get into all your "crazy lady" cleaning (this is what my children call it:) You can take off each register vent and cold air return.... vacuum as far as you can, on top, bottom, and sides of the duct work and the inside of the vent, itself...after having done that take a dryer sheet and tape it to the inside of the vent cover. It smells great and works remarkably well for trapping lots of stuff...I've even seen it aid in trapping smoke residue in a fire. Hope this helps.
