HVAC

The house appears to have always had central heat.  One giant system lived in the basement and heated the whole house.  In the 60's, central air conditioning was added and the system was split (one for the first floor and a new separate system in the attic for the second floor).  The system in the basement has been replaced since then but the attic system is c. 1968.

 Due some termite damage (another post) we removed floors on the main level.  Since we had the floors out, we decided to relocate the registers in the living room, dining room and kitchen.  It involved jack hammering out the concrete slab under the old wood floors and digging two feet deep trenches across three rooms.  It was a lot of work, but it should make the house much more comfortable by minimizing cold/hot spots caused by poorly placed registers.
