Prior to tackling this task we did some research on how exactly to remove an A/C unit and found mixed results. The videos on YouTube were def. amusing but not so informative.
So I will share with you our process.
Crow bar, a couple of scrap wood pieces about 2-3' long, utility knife, ratchet set, heavy duty wire cutters, screw driver, gloves, hammer, sharp putty knife, ladder
Start from the inside by removing the internal face plate, control panel what-have-uuu's with your screw driver/drill, probably actually using the ratchet to remove four large bolts. Then disconnect any wires making sure the electricity is off NO POWER!!! Using the wire cutters, that's pretty much it for the inside work, you are ready to go up top.
Make sure you have a good ladder, or a hulk, or a fork lift to remove the unit once you are finished. Depending on the condition you want the air conditioner once you've removed it!
Our unit had four bolts on the top we took off with the ratchet. Next we broke the plastic covering so we could really see the unit for removal. The next thing you want to do is pry the AC up with the crow bar and get the wood underneath it if you can-using another piece of wood for leverage. (And so you don't damage your rig!!!) It may be really difficult so you might need to cut the foam sealant strip prior so that you can get an area started.
I strongly suggest having a friend there to help!
Once you've got one side lifted up onto the wood you can work around cutting as needed to release the foam strip as you go. You may need to wedge the wood in at both ends if you have a really stubborn AC like we did.
After that you should be able to lift, rip, tear, your AC up, taking care not to damage the roof.
Then you are ready to pitch it! Man overboard! you can take these to the metal recycling center so please don't add it to the landfill.
We filled our 14" square hole with a roof vent! Usually the AC will leave a 14" hole as most manufacturers do this as a universal replacement size, but you will be able to tell once you disconnected the inside AC housing.
Hopefully this will help you, at least give you the courage to get out there and fix it yourself!
