His place, his rules. That's how it works. Green card or not.
My pipes froze and the boiler wasn't accessible. Last time it was a valve/switch and he had to switch a part out. It killed heat to the entire building. So since that was recently, I figured I would have him stop by and check out the boiler room.
Well, he verified that everything was working and that other units had heat and I had a frozen pipe, which happens every year in the same spot. Happened before too, just had to heat a section of wall. Well, I was under a time crunch, so once he turned his back and left, I ripped half that wall out and (with all the power strips, cords, etc) hung 9 hair dryers... why my woman has 9, i dunno, in front of the pipe and within 15 minutes, I had heat.
called him, said shit was good to go, and he said cool, thanks for saving me 500 bucks for fixing that yourself instead of having me call a guy to fix it.
When he came back over to bleed the air out of the lines, I told him that I cut a 6x24 inch hole in the wall to get to the pipe and I installed a floor vent in the hole that i cut out, so now the pipe has room heat to keep it from freezing. He's like, uhhhhhhhhhhhhhhhhhhhhhh... I'm like dude come look.. It was all professionally installed within an hour.
Bam. 1 seriously happy landlord.
