No refrigerant. Just a stream of cold air coming from a vent on the unit.
Well, there's probably a refrigerant in there somewhere. But it's not like HVAC system with a refrigerant line and a compressor outside. It's all contained within the unit, and cold air just pours out. You can direct that using ducts.
No, I meant they hate you specifically. It's completely unjustified, but topologists are jerks. They wouldn't go into details, but they blame you for 'The Incident'.
I almost built that for my last house but ended up moving before I could. It wouldn't need much, just an extra pipe with a baffle and a door that opens internally.
Eh, not in comparison. Burning oil counteracts your AC, so both fight your HVAC somehow. And heat pumps are more than 100% efficient. I.e they can heat the water more than the amount of energy spent.
My current boss says that any downtime counts because the services are supposed to work together and a single outage affects user experience. I like your approach of "if it's not fully down it doesn't count, fuck the users" better.

"Every cell division can result in random mutations. Also DNA of single cells can mutate due to radiation and other events. So you would not get a 100% match in a DNA test, wenn you sequence a single cell. Certain cell types also change their DNA permanently (B and T lymphocytes to be able to produce the same antibodies permanently). However, when you sequence a sample of a lot of cells these mutations won't be visible in the results because it would be just noise. So overall, the result should be close to 100% but there will always be sequencing errors as well.. And there are telomers sequences, which get shorter every cell division. So these will be different as well. On the other hand when you look at tumor/cancer the DNA can be very different. But this is a topic for itself. I hope this helped!"
