Last year's rate was $2.02 per hundred cubic feet (ccf)
PLUS an additional 159 percent for the accompanying
sewage dump [a], or $5.2318 per ccf.
With 750 gallons per ccf, that's $0.0069, or
about 0.7 cents (3/4 of a cent) per gallon.
Note that this is _last year's_ rate. There's
been an 11 percent increase propsed
for this year. I'm pretty sure that's the
final number, but there might be some
slight adjustments in the pipeline.
[a] for most customers the pipeline water
is the same quantity as the sewage dump. The
city will do separate metering if
there's a major difference - for example,
if you're using well water for your
car wash and dumping it in the sewer.
Knowledge may be power, but communications is the key
They are all pretty ineffecient. Better effeciency can be had by
spending more money on central A/C (higher SEER) or a mini-split (for
example Fujitsu's run up to a whopping 21 SEER). In both of those
cases you would need a professional install.
That being said, a dinky little A/C like that, even running at 8 SEER
or something crappy like that, is not going to break the bank just
because it's not big anyhow, and you probably don't run it 24/7.
Additionally, depending on your situation, wasting some electricity
dollars may be ok if the alternatives (putting central A/C in your
rental unit or something) don't make sense. This "ineffeciency" may
add up to something like $10 a month (guessing here) so it may not
years ago i got into a heated argument with the fellow in charge of
building maintence where i worked. the window AC unit was ineffective
having been vented into a compressor machine room. in the summer the
temperature in there must of been near 200 degrees. the jerk claimed
that had no effect on the ac operation...
clearly he was wrong, and either too stupid to realize it or plain
lazy and didnt want to move the unit. worse the company wanted us
looking professional in long sleeve dress shirts and ties, in a
office near 90 degrees..........
heck they really wanted us in suits.........
I've observed that head pressure is more or less directly related to
condenser temperature, if it was 200 degrees in there the pressure must have
been through the roof. No wonder it quit working.
They're all pretty much the same, there's virtually no difference at all
between the small rotary compressors they use, and they're all about the
same efficiency (not very) due to mandated standards. Buy one that has the
features and cosmetic design you like.
I've had a Sunpentown 13000 BTU unit for 3 years. It's
very effective, efficient, and the condensate goes out
with the air exhaust. I installed a dryer vent through
the wall to regain the full use of my window. It keeps
the computer room cool and doesn't cost a lot to run.
Ordering over the Internet, including shipping, was
comparable in price to buying a 9000 btu unit with a much
lower efficiency rating locally.
The quality of this unit really surprised me.

I use a portable split A/C. If you pay more, you can get portable split
A/C with an aggregate installed in an external unit. As far as I can
remember the external unit can not be put outside the house as it is
raining, otherwise it can be put outside. I put the external unit in a
small room with open window and additionally put a fan in that room
directed to the window to blow hot air outside.
Well, I cannot find a link now but remember the price, it was about 2000
USD for brand new one. There is a small rectangular flexible cable
connecting units. In mine, the cable dimension is 2 x 4 centimetres and
length about 2 metres. I put it through a tiny hole at the bottom of the
door in the corner. The hole is hardly visible.
