This is Turtle.
Here is something to look at and why it went this away.
I had a 4 ton 13 seer Goodman condenser and a Arcoaire 5 ton evaperator coil
expanion valve with Arcoaire 100k gas furnace set up in my house. I had run it
for about 6 or 7 years or so and out of the blue the piston Compressor bite the
dirty. I changed out the condenser to a 3.5 ton 8 seer second hand 1982 Rheem
condenser till i could get time to get me a matching condenser Ordered at the
warehouse. this part of the country no body wants anything above 10 seer and the
warehouses don't carry much in the line of 13 or 14 seer.
So i was running a Goodman 13 seer 4 ton condenser and a Arcoaire 5 ton expanion
valve evaperator valve type and 5 ton blower gas Arcoaire furnace in the
beginning. I was getting about at the time the highest electric bill of $200.00.
Then I just put a 3.5 ton 1982 second hand condenser in the place of the 4 ton
13 seer goodman condenser units and my electric bill dropped down by $50.00 or
so. The highest electric bill that year was $150.00 and so has been the case for
a couple of years now.
So Why did my cost to operate drop when i only changed out a Goodman 4 ton 13
seer condenser unit to a Rheem 3.5 ton 8 seer condenser unit ? How does going
from a 13 SEER to a 8 SEER save money ? This does not seem right here.
