Installing a/c: final installation of a/c unit and trim work

The above picture shows the side panel behind the installed a/c unit open for ventilation. I just have the vented panel propped open with a paint stick when using the a/c. The previous post showed how I installed the ventilation fans.

Now that the ventilation fans are installed, it's time to permanently install the a/c unit.  I centered the unit in the cabinet, tightened the furniture glides on both sides (these are pictured in an earlier post), and installed two pieces of wood across the top (pictured above). The two wood pieces keeps the unit from bouncing up and down.

Now I started working on the trim around the unit to make it look better. I had some scrap metal trim from my Grandmother's house. I put it around the edge of the cabinet.


This is a backed up view of the metal edge trim.

I plan to put a panel around the unit. I needed to install some wood strips in the cabinet to keep the panel from sliding around. I got some scrap pieces of the laminate and plywood I'm planning to use.

I use these scrap pieces to mark where to install the bracing to make sure there's enough space for the panel to slide in. 

I cut my plywood and make sure it fits around the unit.

This is a picture of the installed top and right side wood bracing that will be behind the panel. I had to take the right side brace back out and cut a 45 degree cut along the edge so that the panel would slide in easier. 

This is the piece of wood that will be behind the left side of the panel. I cut it at a 45 degree angle so the panel would slide in easier.

This is the wood brace for the left side installed inside the cabinet.



I used brass round head screws to attach the wood braces. This is the right side.



I used the same baby blue laminate for the panel that we used for the kitchen counter. I used contact cement to glue the laminate to the piece of plywood. Then trimmed the laminate with a router.

This is the right side wood brace I installed behind the panel. This picture shows the angle I mentioned cutting a couple of pictures back. I still haven't learned how to rearrange the pictures if I post them wrong.

This shows the panel slid into place. It's easier if you remove the front panel of the unit. To get the panel in, you slide one side in between the front cabinet trim and the wood braces installed inside the cabinet. Then, you bend the middle of the panel out and slide the other side in.


I measured and cut three pieces of birch stained and clear coated to match the cabinets.

I used brass round head screws to attach across the panel at the top, middle, and bottom. This gives it  more of a built in look and keeps the laminated plywood from bowing and warping. All the empty space behind the panel is needed to vent the hot air away from the unit and out the side of the trailer. To use the a/c unit I turn it on, flip the switch inside the closet (discussed in the ventilating the a/c post) to turn on fans for pulling fresh air in (through the top vent on the exterior side of trailer), open up the exterior panel behind the a/c unit, and turn on the fan installed behind the a/c unit that pulls the hot air out.
