Air conditioners

This, I mean, we should set inhabitable zone such as subtropical zone and all live in the comfy area.
fucking hate living in subtropical zone with these high temp high humidity weathers

And yeah, those AC seem to be simple enough for DIYer to fix. So getting EPA/F-gas license might worth it.

Windows vs Mini-split vs Central air vs Mobile

Sort it please

pretty much. places like israel, phoenix arizona, baghdad, riyhad.
europe doesn't really have hot deserts (except maybe some parts of spain)

I would love me some euro-windows. they were greatly insulated. my concern is how to make the best out of them in hot humid 'murrican environments. where you place mosquito screen? and are they suited for non-concrete houses (aka cheap american wood constructions)

>It will pump gas, just like during normal operation.
I meant fluid in the scientific sense, not a literal liquid
>Yes. But compressors are pretty reliable.
Still subject to wear. I live in the desert and a unit generally lasts 10 years cooling in 100+ heat for 7-8 months a year or so. So like 80 months of use give or take. additional use for heating for those other 4 months, granted in the cool so less extreme heat wear, will lower the lifespan by a bit. Doubt it will be halved, but that extra 30% will probably cut 15-20% off the lifespan, or 12-15 months.
>For gas heater, you have potential of fire, if it was installed by someone like me.
That's why they have multiple redundant safeties, as well as professionals to install them. I'm willing to bet (because I couldn't find anything with a quick search) that most to all of gas heater fires actually stem from gas leaks other than the heater, and it either lights off the built up leaked gas, or it's entirely unrelated but gets blamed because it makes the most sense. They wouldn't still use them en mass in new constructions (like my house) if they were that horrifically dangerous *cough* fireplace *cough*

>where you place mosquito screen?
From the outside somehow.
>and are they suited for non-concrete houses (aka cheap american wood constructions)
Yes. Russians install them in wooden house no problem.

Idk, I don't like them, hinges are too complex for me. I like japanese aluminium sliding windows.

my window unit is spitting water out the front but isnt flooded in the back metal part. why?

Cuz the evaporator is the cold part and the condenser is the hot part? And water condenses on things that are below the dew point?

Tilt it back

Heat pumps are less efficient and cost more than burning natural gas for heat. They are useful for places that don't have central heating as common devices, like in Japan.
Swamp coolers very much work but only to a point and they have a slight negative of raising the humidity and also use water. They are good for large amounts of small temperature change cooling, so something like an out building or garage that is often opened to the outside air.
