Some friends of mine recently bought an old fixer-upper. The house is 40 years old, and no one has lived in the building for two decades. The place is falling apart, but it has good bones and structure. My friends had a full inspection performed, before they decided to make an offer on the house. The inspector agreed that the house foundation was still in good shape. My friends got the house for a steal, but they have spent a lot of money fixing various problems along the way. The last huge problem cost a fortune to fix. My friend was working in the Attic, when he noticed some problems with the ductwork. Several areas were detached, allowing pollutants and harmful bacteria to enter the indoor air system. My friend was going to fix the duct work on his own, until he realized how significant the repair would be. My friend found at least three pieces of ductwork that needed to be replaced. He contacted a local heating and air conditioning company that offered ductwork cleaning and repair services. The heating and air conditioning technician spent most of the afternoon working on the ductwork. He replaced two large sections of ducting, and sealed all of cracks and crevices. The whole job was expensive, but necessary. If my friend is going to fix up the place and live there, he will need to have proper airflow in the house. That means working on the ductwork and fixing up the heating and air conditioning system. In a few months, most of the major renovations will be completed. Then my friend is going to have one huge housewarming party.
