My apartment has a built in Air conditioner unit. The brand is ICE CAP and it doesnt look like there is any way to remove it as its built into the cabinet frame that has an external exhaust outside. Lately the AC cooling is not cool enough and I'm thinking it just needs a freon recharge. I hear alot of horror stories when hiring an HVAC company to do recharges as they charge you extra for unreleated services.

Below is the picture of the unit. I was able to manage to get the casing off and see a piping that looks like I can unscrew. I'd imagine it is where I would recharge freon, but not exactly sure as I have never done this before. I have a zoom in view of it also.

• Judging from the pics, can I recharge Freon without removing the entire unit?
• Is the valve there for recharging Freon?
