/diy/ - Do It Yourself

I bought an old mobile home to get out of the shitty living conditions I was in before. I am worried about the Sacramento heat. This thing is basically a tin box with almost no insulation. There is a single 15000 btu wall unit which that I am reasonably certain will not keep up with >100F summers we have here. Short of installing a mini split heat pump, what else can a poorfag do to keep cool or augment the cooling of this wall unit.

Attn Knuckleheads: THIS is what you Crave. "Ductless A/C." I have a two ton unit cooling my whole 1000 sq.ft.+ downstairs, and I installed it myself. Granted, it's $1k vs. $500, but it's permanent, works, AND IS INSANELY QUIET!!! Plus it does heat down to 20F. DID I MENTION THAT YOU CAN'T EVEN HEAR IT RUNNING??? I made the mistake of putting a hotel-standard, $800 "Packaged Terminal Air Conditioner" in my bedroom, and it sucks donkey balls because it's SO NOISY!!! Why can't they be quiet like the split mount? These things just work, and you can buy them pre-charged w/freon and just install them yourself.

FYI - single hose A/Cs blow the hot air out, which sucks the hot outside air back in thru holes in your house. They may claim 18,000 BTU, but half of that is wasted on bringing in outside air.

My old AC at home (at least 15yo) stops blowing hot air far too soon, when the room is still cold, even when it's set to the highest temp' and on the highest blower setting. Any easy explanation/fix I can try, before calling the cheap greedy landlord who will likely drag his feet for months before (if) doing anything?
