[left]I have a Coleman/mix Honeywell furnace. Runs on two wires. I’m looking to add a fan wire to be operate off of nest. The furnace has fan / limit control system Honeywell L4064B, Heat system transformer, and the main two wires hook to a 3 way where two wire goes the HST then to the L4064B. Is there way I can add a g (fan) wire from nest. If so, where do I hook up to in the furnace?[/left]

I have a horizontal AC unit in my little casita separate from the main house, Fujitsu model ARU12RLF. It has it's own unit attached to the house. It's only about 9 months old, so i can get the AC company out but given we are in a California heatwave it could take a while. It's been dripping a lot from the inlet in the ceiling and all over the floor (yellowish water). I went into the crawl space and the drain pipe is open and not connected. You'll see from the pipes there is no pipe to an external drain. The long white pipe to the right does go outside the house, but it's not connected to the drain. In one of the photos you'll see a drain plug (bottom right) that is not attached. The instruction manual says use the drain plug if the unit is naturally draining. So my question 1. How do I know if it's naturally draining? If it is, should I just insert the plug onto the drain and then test it again? 2. If it's not naturally draining, then I have a bigger issue in that the drain was never connected, which would be a huge issue the contractor needs to fix Thanks in advance, I tried to lay everything out as clearly as i can.
