I took a look at a house in western Long Island that was in need of insulation. While there, the owner pointed out his current HVAC system.
It consists of a single 3 ton condenser with two very large air handlers in series. The lineset goes to Air handler 1 and then to AIr handler 2. I couldn't get to the nameplate to check the size of the air handlers.. but they looked at least 3 tons each.
The system works.. but I have never heard of such an arrangement. ANyone elese here ever see something like this?
