Experience with A/C unit under seat or in trunk

I have a 30 coupe with a recessed firewall, providing no room for an in dash a/c unit. I looked into the minis, mocked up a cardbord unit and no-go.

I bought a complete unit at the swap meet over the weekend and I believe it will fit under the seat or just behind it, OR I WILL MIKE IT FIT!

The condensor is going in the grille and I'm wondering if there's any issues with the length of hoses or anything else.

No issues with hose length, how you gonna handle the air distribution.

How about replacing the firewall with a flat one, they are availiable and not that difficult to install.

My cousin had a 56 Lincoln Mark II that had the AC vents in the headliner, there was a vent on each corner of the roof and it worked great. He claimed that was superior to dash mounted vents since cold air goes down. I would think that if you mounted it in the trunk you could think about putting the vents there.

Most early 50s cars did have trunk mounted AC systems with vents in the deck. Should be easy to rig up!

Thanks guys.
There is enough room in the corners, between back of the seat and the sail panel to mount a vent on each side going straight up toward the roof. I thought this goes with the cold air theory, as it will hit the roof, which is really close to my head, and drift downward.
Plus two vents below the seat, aimed at the firewall, keeping it cooled off down there.
My engine & Trans is already mounted as far back as it can against the recessed firewall. Moving it forward wouldn't be that easy now.

under seat ac

I put AC under the seat of a 38 Chevy pickup. I just made a box under the seats and put the vents in the front of the box. The cab is small, the unit really cooled well- I know that it doesn't seem that it work well, but in my case it did. When I used to do Porsches, I've put condensers under the car and even in fenderwells with remote fans. Bill

I think that idea is a good one myself..

My Willys has the same room problem so I put the evaporator in the trunk with air ducts in the walls of the car that exit near the passengers and the condenser is about 1' square with a built-in fan from one of those small import cars and is mounted under the floor under the driver. Works OK but needs more fan on the evaporator. Those long ducts restrict air flow and my fan doesn't have enough oomph to move enough air. When I tear it down for a rebuild next time, I'll put in a much stronger fan.
