if an A/C is low on freon, does it use more energy or not?

obviously it doesn;t get as cold, so it has to run longer

but is the power demand the same, or less?

is the total energy used the same, or less, or more?

More because efficiency drops.

oh
good answer
i asked on 'yahoo answers' and i got every answer possible
more, less, the same

From what I remember, I had my CAC charged with freon a few years ago
while an Amprobe was hooked up to the compressor, and I remeber seeing
the current draw go up slighty as the freon was being pumped in,
probably due to the added pressure from the freon the compressor had
to push.

oh wait
this makes it sound like it could be using less power..

But the efficiency isn't as good...don't you think if the overall
efficiency were better the manufacturer would design it to run there?

No, because when it is slightly undercharged, the suction pressure is less,
lowering the temperature at the evaporator. It runs quite cold for a while,
then ices over. It needs to run with the evaporator at the design temperature.

That's what I was alluding to...

It'll work harder while it's running, but not run as long.

what?that makes it sound like it;s better to run low on freon

that can;t be right

how can it not run as long?
it won;t be getting as cold, it has to run longer..

I have retired from the field and I can tell you that when your system runs
low on refrigerant, it cost you more. When the system loses charge you now
lose the size. I mean if you are using a 3-ton system and when the system
loses charge, you now are using a 2 to 2.5-ton system to cool the same
house.

When it's charged, it'll work harder while running, but not run as long
for the same cooling. The cumulative energy will be less.
