North
Carolina Alternative Energy Corp.
This non-profit organization examined air
conditioning manufactures' efficiencies versus the
actual efficiencies that resulted after installation.
-
90% of
the systems tested exhibited some sort of
energy-wasting problem.
-
50% had
an improper refrigerant charge.
-
40%
failed to meet minimum air flow criterion.
-
A
deficiency of only 20% in indoor air flow reduces
the SEER by 17%
-
A 155°
return air leak from a 120° attic could reduce
a 12 SEER to a 6 SEER!
Texas A&M
University
Found that a 23% refrigerant undercharge could
result in a 52% efficiency loss.
Pacific
Gas & Electric
Found the average heating repair savings for
(1) repair of disconnected ducts was 15%
(2) repair of grill leakage was 7.5%
(3) correct air flow was 15%
(4) repair refrigerant leaks and correct refrigerant
charge was 18.4%
Lakeland
Electric & water
Researchers found that by repairing leaking duct
work, cooling energy was reduced by an average of
17%
Louisiana
State University
and Gulf States Utilities found consumers could see
about $30.00 per month just by making sure that air
conditioning system is cleaned and serviced regularly.
-
LSU
determined that without proper filtration, over
time, air flow can be reduced by over 30%
-
System
capacity can be reduced by over 12%
