Hi,My tenant wrote on the rental checklist that cold air is coming through under the kitchen counter, around the heater, and into the mechanical room. I don't know that it should have gone on the rental checklist, but since they mention it, it seems like something I need to address. The tenant is paying their own heat. My plan is to go and inspect the cold air and possibly seal it with grout or fire-safe foam. These same tenants have made multiple other complaints and submitted this rental checklist late.thanks,
