How do you install split system air conditioning?

Answer 1

Exactly what I am doing now. My furnace is old and ineffiecient so I bought a new, ineffiecient furnace. (80%) natuaral gas. I also bought a cooling coil that fits on top (upflow furnace) of the furnace. I bought a condensing unit that will go outside and be wired to the furnace and thermostat and connected to the coil with refriderant lines. All of this was less than half of what an installer quoted for just a new furnace! The new furnace is the exact dimensions of the old, so it is a plug and play situation. However, I need to have a licensed plumber make the connections, which then need to be inspected by the town. I have an EPA 608 certification to make the AC connections, but that must be inspected as well. I have to run a whole new circuit (220V) to the wall where the outside unit will sit. So for less than $2,000 I will replace my old junky furnace for a new split system furnace/AC system. I also replaced my old thermostat for a new digital programable thermostat for $49. This should save $ as you can program less heat or cool when everyone is at work.
