Fabricated a polycarbonate insert to adapt it to a crank-out window and use unit in our master bedroom
on June 18, 2016
Purchased this after reading Consumer Reports and reviews on different sites. Consumer Reports doesn't think any of the portables are all that great, but for people who have no other options, they rated this the highest. My house has all Andersen crank out windows, so my choices were install central a/c or purchase a portable a/c and make some adaptations (no a casement a/c unit will not work in a crank out window). I ordered it through Amazon Prime and while shipping was free, the price was pretty steep. A month later I see the price has dropped by $50, which quite honestly makes me feel ripped off. After the portable a/c was delivered, I took the vent hose attachments to a local glass shop together with one of my Andersen window screens to use as a template and paid them to make me a polycarbonate window the same size, with cut outs for the intake and exhaust. When it is hot out we now remove the screen from the window, insert the polycarbonate window and hook the portable a/c to it. The P12B isn't quiet, but it isn't totally unbearable. It's biggest drawback for me is the ugly flex hoses that attach to the window and the amount of floor space the machine takes up. It does work well to cool down our 228 sq ft master bedroom -we've been using this unit a/c to keep the room at 70 degrees while it is 90 degrees and humid outside. I did insulate the vent hoses as I understand the exhaust hose in particular can get very hot and throw that heat back in the room. A lot of reviewers bought Reflectix pipe wrap available on Amazon to accomplish this, but I bought a product called Cool-aide that is specifically designed for this purpose (Amazon doesn't offer it, I found it through a web search). It is a polyethylene sleeve with several layers of recycled cellulose inside of it that easily slips over the flex hose).
As far as the supplies to make a portable a/c unit work with an Andersen crank-out window, if you are handy you can do the work using the following supplies that are all available on Amazon: a Lexan Sheet - Polycarbonate 1/8" thick (.118) (don't use plexiglass, it is too brittle); CRL-Sash Universal Storm Window Frame (sold in 12' length and can be cut down to frame the polycarbonate), CRL-Sash Square Storm Window Corner for CRL-Sash Square Cut Fabrication (used on the corners of the storm sash frame); silicone sealant for around the intake & exhaust vent holes, and some kind of fastener to hold the new window where the screen would normally sit (we used CRL Andersen Knife Latch and screwed them to the outside of the storm sash framing the polycarbonate - they lock right into the slots where the Andersen bug screen would normally be).
