My wife and I bought a new house last month. Well the house is actually very aged but it is very new to us. In order to afford a house of our own, we had to buy something that needed repairs. Luckily, my wife is very handy with tools. She worked in the construction industry for twenty years before getting her general contractors license. The old cottage is in a nice, established neighborhood. The previous owners lived there for 50 years. Unfortunately, they hoarded a lot of items in the house. We spent the first week doing some major cleaning. Each room had its own particular smell. None of the smells were very nice. Some of the rooms smelled like cats and dogs and some of the rooms smelled like tobacco and cigars. We had to seal the floors and prime the walls in order to get rid of many of the smells. The old ventilation system was riddled with problems. The ventilation system was falling apart and there were many spots in the attic that needed to be repaired. Every time we turned on the central HVAC system, we could smell the horrible odors in the atmosphere again. My wife and I decided to install a ductless HVAC system instead of make all of those obviously needed repairs. The ductless HVAC system does not require any ventilation ductwork at all. The ductless HVAC system is an all-in-one machine. We have a ductless HVAC unit in our master bedroom and another ductless HVAC unit in the living room. Together, they provide plenty of cool air for the entire place.
