@Sotiredofthisshit , you're simply full of shit.

My spouse and I installed an A/C unit last weekend that required some light assembly, and as two women, had zero problems doing a simple job like this, after removing *everything* from the packaging box - including all styrofoam and instructions - which always come in a sealed plastic bag, along with all operational, warranty and registration information.
It isn't fucking rocket science, whether it's a central heat/air unit or a window unit, the main difference is the 220 power supply for a central A/C really needs it's own breaker (yeah, we know how to do that too, even back when we were your age) and the tedious work is connecting the lengths of vent hosing for a central unit to the home's intake area; versus slide it in, balance it, secure the window on the frame and plug it into a 110 outlet for a window A/C.
We've done both easily, and multiple times.
But please, do keep talking, as both prosecutors and corporate attorneys use Google
extensively against criminals and civil suit claimants, and you've given them all more than enough already to use against you, both for prosecution and any civil case you attempt to bring against the A/C manufacturer - which if you lose, you must pay all court costs and attorneys fees, and corporate lawyer's fees alone will run you a minimum of $100K.
Either way, you've fried your own ass with your posting here.
