My spouse plus I have a Summer house down south. The apartment sits locked up slim for weeks before all of us get down to it. The first month all of us are back is consistently the worst month of our trip. The apartment is consistently a total mess. The surfaces are all dusty plus there are dead bugs everywhere. The toilets plus shower all get moldy due to the water kneeling stationary. The Heating as well as Air Conditioning component also needs some work. The air filter should be changed due to the dust plus stale air. The inside of the heating plus cooling component could use some cleaning too. You never think what has crawled plus died inside of the Heating as well as Air Conditioning. The worst is checking out the ductwork attached. The outdoor vent is in the garden. There could be dirt, leaves or dead animals in the outside vent. Then if all of us turn on the Heating as well as Air Conditioning, the air blows over that debris plus pollutes the air quality. It is consistently a terrifying moment checking the vent to see what got into the Heating as well as Air Conditioning ducts. My spouse plus I take turns looking inside of it. The best is when it is a little bit of dirt. The people I was with and I just stick a long pole with a towel attached to it through the ductworks. The worst was when a squirrel got into the Heating as well as Air Conditioning duct plus died. The people I was with and I got a professional ductwork cleaning dealer into the apartment to take care of that 1. It was super stinky plus gross. Now the many of us forever worry about it happening again.
