Does anyone know if there is a dishwasher that has an internal air vent or if one event exists?? We recently purchased a home and it has a Bosch dishwasher but with no air vent.

Not sure if any built in but if the drain hose is looped higher than its connection point it works just the same. Just look under the sink and see if it is looped

I just moved into a new development of 170 unit townhouses and the condensers are inside the unit, in a closet in the loft - over my bed. When the A/C is on "it is so loud". Someone told me the builder did not put enough insulation around the condenser. The builder tells me "that will not do" anything. He called me today & said he will do whatever I want, but he nor I know the answer.
