How do I get rid of tape very old that has dried on the outside of our window frames of plastic?

Tape mask has been in the outer frame of our PVC windows for some years. We have bought the house and want to redecorate. I'm burning aprehensive tape out and do not know if there is a chemical to get rid of him.

Try eucalyptus oil. Its fantastic and natural. You can get it in liquid or aerosol. Go to the raw range and you should find in supermarkets is safe to use on the surface that you described. You can remove the tape immediately, or you may have to leave stand 5 minutes. Eucalyptus oil removes old glue almost anything permanent, permanent marker, old paint etc. Just be careful tho surface, and can lift some paintings. Hope this helps.

Make the window air conditioning units require minimum width?

I have a 18.75 "wide sash is and it is 21" high. There are air conditioning units out there that are exactly 18.5 "wide, but say that their user manuals that you need a minimum of 23 inches. Is it OK to run on the opening side without the tape?

Yes, the side pieces that come with the unit are simply not used. What you do is mount the drive without them, then fill the holes in the sides with foam insulation to keep bugs out. Foam can be purchased at the same places that sell air conditioners. The sole purpose of the side pieces that normally * * slide sideways towards the window frame is to keep insects and separate the hot outside air exchanger temperature inside the air, some of the foam will be better to do anyway.
