I just did a test to see how much electricity my house uses in this
heatwave. We had a high of 95 yesterday, it got down to low 80s
overnight. I measured from 9AM yesterday to 9AM today. 46Kwh, which
at my rates is about $6. That is for the whole 3100 sq ft house,
including central AC set to 77. House is partially shaded.
So, I'm quite happy with my 5 year old Rheem system. It's just
a 14 SEER, basic system, nothing fancy other than an ECM blower
motor. It's using a PSC
motor on the condenser unit, because the fancy ECM one died and
I replaced it with this $80 one that hopefully will last because
it doesn't have the electronic crap.
I think usage here without either heat or AC is around $70 a month.
If we had an entire month of heatwave like this, my bill would
be ~$180, which seems very reasonable, with about $110 attibutable
to the AC. My summer bills have been
very modest, but usually we only have a real hot day or two, so
I was curious to see how it performs during an exceptional day.
It's definitely using a lot less than the old system, probably
1/2 the electricity. Yipee!
Heatwave?? In the summertime SW desert we generally run daily highs of
106 to 118.
My 1800 sq ft house costs around $220/mo. Not sure how much is AC.
However my kids with bigger houses run from $300 to $600/mo which is not
unusual here. (The good news is I've never had to shovel snow.)
Yeah, this is by far the hottest summer of my life.
And last summer was one of the coolest, only 4 or maybe 6 days over
this summer 34 so far counting today and one or two more predicted.
Do you remember my plan to blow air from the basement up to the second
floor. I found only one fan the right diameter, but it was perfect,
and it sits in teh mouth of the laundry chute. (When I have laundry,
I take the fan out and through the clothes down the chute. Takes 10
extra seconds to take it out and 20 to put it back in.)
Well the air it blows is very cool, 10 degrees below what's here, but
the chute is right next to the stairwell, which has no doors, so I
think a lot of it falls down the stairs. When I'm in the bathroom
right across the hall from the chute it's really nice.
But in the office, I dont' feel an effect. I looked into getting a
hose, and a 20 foot, 8" hose is guess how much, about 300 dollars!
But a similar hose, 4" diameter, for a clothes dryer is 20. Since
the amount of material is only half, I don't know why the ratio is
1:15. But anyhow, for next summer, I may make an adapter so I can use
the 4" hose with the 8 1/2 " fan. I'm sure that will work well.
I have a "portable" AC in the bedroom and though i'm sure it's not as
efficient as central AC, I'm sure it's a lot cheaper than doing the
whole house, even though the first floor and the basement are still
pretty comfortable. IF the computer will still in the basement and
the loft bed there wasn't making me claustrophobic, which it didn't
used to do, I'd be fine in the basement..
Ours has been hot for us too. Believe the news said it is
the 6th hottest summer on record. IIRC around 26 days over
110 so far. It's killed around 6 local hikers (and 1 dog)
who underestimated the heat danger.
In the 40's when I moved to the SW desert most people here
used swamp coolers. When the humidity is low they can bring
the inside temperature down as much as 30 degrees. However
when the dew point gets above 55 coolers suck. But they were
easy on the electric bill at around 25% the cost of AC.
BTW they also actually had swamp coolers for cars that hung
outside on the window. But most of us just turned the wing
all the way around for more air which helped except when it
swept a bee into the passenger compartment.
I stayed someplace for a few days that had a swamp cooler. It was in
the hall and even with my door open, it didn't have much effect on me.
So I went to the back yard to sleep, and it was made out of gravel,
bigger than normal gravel, so it wasn't very pleasant, and it was
But FTR, that's not the same as a portable AC, which is a real AC, but
it's not in the window or wall, and the condenser is not outside, but
right in the same device, about the size and shape of a floor radio,
if you know what that is. Then it has usually one, sometimes two, 4"
vinyl hoses, one that vents the heated air through the window to the
outside. The inefficiency is mostly that the warm hose radiates some
of the heat back, and the thing in the window can leak and isn't
insulated at best. And maybe the whole cooling part is not efficient
though it could be.
You need to empty the condensed water periodically, or you can connect
a hose, like I did and I drilled a hole in the floor, in the closet,
where the second floor overhangs the first floor, in the corner in the
rear, so it's not noticeable at all. In fact, I haven't even checked
if water is comign out. It could be that insects clogged the tube
last fall/winter/spring, but the floor is dry so I guess not.

I can wear less in the summer and I can shovel the snow all winter.
You can't dress for floods and you sure can't shovel water.
I feel for those poor souls in Louisiana, Texas, Wisconsin and
on and on.
3 pages of floods in 2016 alone:

Yes, I feel terrible for the people in flood zones.
Although for the first 20 years I lived here, I wondered if I was in
one. The flood people said I was. I live right next to a stream
that can rise from 8" deep to 10' deep within a day, most of that
within 6 hours. On a nice night when the windows were open, the roar
of the water has been so loud it woke me up.
Baltimore has been very interested in flooding since Hurricane Agnes,
I think it is, 1975 maybe, during which a few houses were washed away,
so they have automated solar-powered remote stream level meters on all
the streams, and tried to not issue building permits where flooding
was possible. Though I'm told that during construction here, one
house was damaged by flooding and they ??abandoned that lot, or maybe
hoped it woudn't happen again, or maybe it never happened.
In the last year I found a government webpage which had a drawing of
my n'hood and showed where the water is during flood stage. And I'm
glad to say that the drawing (a prediction I presume) is wrong.
Becausea it has my front yard and that of several houses to the left
of mine flooded, as well as the street in front of these houses. That
has never happened in 37 years and I have reasons to think think it
could not, so the whole rating of my property as a flood zone seems
likely to be in error. I'm very happy to realize that.
Not to compare a flooded basement with what those people have, it's
still related: When the water rises to 10' or a little lower, it
overflows the manholes on the sewer that paralleles the stream, fills
the sewer and backs up through the laundry sinks in my house, the
house next to it at the same height, and the two next to that, only a
llittle higher (The houses next to those two are only a little higher
still but they don't have the problem.) One would think the water in
the sink and on the floor would be disgusting, but since the ratio of
rain-water to sewer water is maybe a million to one, at least 100,000
to one, it hasn't been at all.
But I still don't want the water, getting soaked up by anything that
We had rain just two weeks ago and despite what I told them, all 3 of
my floodable neighbors had flooded basements. My next door n'bor had
big rugs drying on his lawn for two days. I told him what to do, I
even did half of it for him. I told him he needed a stopper in the
sink, with a piece of 1x jambed in between the stopper and a shelf he
has, fortunately, right above the sink, with enough weight on the
shelf, or it screwed well to the wall, that the water can't push out
the stopper. And I measured and cut him the right piece of wood. And
I told him several times, it has to be plugged all the time becuase
you won't be around to plug it when it rains. And I knew he'd mess up
because the girl who lived here before him messed up, and I told her
several times. And he was sleeping when it flooded.
But I am surprised about the other two, who have been here for quite a
while, including previous overflow-level streams**, and I told them
what to do but I guess they didnt' do it. **With one or both, I
showed her how to siphon the water out of the sink, into the sump, the
last time, and I know I talked about plugging it. This time, like
99% of the time, I had my sink plugged and I got no water.
If the water were able to stay at maximum or a little less for long
enough, and the sinks were not plugged, the basements would fill with
water to a height of 6 or 7 feet. But the stream only stays that
high for an hour or two, and the sink is a buffer, and boxes have
soaked up a bunch, but before I learned to keep the sink plugged all
the time, I've only had a quarter inch on the floor, and only once did
it get to the next room.
Agnes was the only time my street in Md flooded. I knew enough to buy
a lot at the top of the hill so I was OK but I had a couple of
neighbors who had 3' of water running through their house. They
actually built a house at the bottom of the hill (next to where the
creek was 12' over the bank) a few years later but I never heard of
another flood like that there. It is certainly not a question of "if"

Do you remember their address?
I think Ellicott City had big trouble during Agnes, and 2 weeks ago it
had big trouble again but not in the exact same place. It's at the
bottom of a hill too.
And I'm at the bottom of a hill too. I found an online map with
better topograhpy, and I think the hill is 40 feet high which is not
that much but it still gathers a lot of water.
The stream only goes 4 or 5 miles farther upstream, so that limits how
high the flood can be.
You are looking for a lot of joules
These days a panel protector like the ones Ditek sells are cheap
enough to put right on your A/C disconnect
Since I was feeding my air handler with 6ga for the toaster wire heat
I extended the #6 ground all the way to the condenser and drove a rod.
If it is not bonded to the service ground, with a #6 minimum, it is
not worth doing (or legal).
How many Joules is a lot of Joules???
