So I recently purchased a house in LI, NY. It has a fairly antiquated HVAC system. It is one system, with three automatic baffles for three zones. Uses a traditional central air, with oil burner for heat.
The existing AC is a Trane BX1000 5 ton unit. It is 15 years old and according to one of the web calculators, upgrading will see a 40% improvement in efficiency.
The oil heater (burner) is an Anderson Air Ultra 80. Not sure of the age, but would guess its around the same age, if not older then the aircon.
So here are the questions. I want to move to two zones, (upstairs/downstairs).
Can I use most of my existing duct work and how much modification/additions need to be made.
Any reason to keep the baffles? Does one move these close to each room?
I have access to propane, but not natgas, any reason to convert to propane?
Finally, was thinking American Standard for both air and heat. Any reason not to use?
Anyone want to hazard a guess at what this might all cost?
