Without the right installation, you could waste 50 cents
of every energy dollar and be uncomfortable as well!

North Carolina Alternative Energy Corp.
This non-profit organization examined air conditioning manufacturers' efficiencies versus the actual efficiencies that resulted after installation.

• 90% of the units tested exhibited some sort of energy-wasting problem
• 50% had an improper refrigerant charge
• 40% failed to meet minimum air flow criterion. 20% were barely inside the range specified by manufacturers.
• A deficiency of 20% in air flow reduces the SEER rating by 17%.
• A 15% return air leak from a 120 degree attic could reduce a 12 SEER to 6!

Texas A&M University
found a 23% refrigerant undercharge could result in a 52% efficiency loss

Pacific Gas & Electric
found the average heating energy savings for (1) repair of disconnected ducts was 15% (2) repair of diffuser leakage 7.5% (3) correcting low air flow 5.6% (4) repairing leaks and correcting refrigerant charge 18.4%

Lakeland Electric & Water
researchers found that by repairing leaking duct work, cooling energy was reduced by an average of 17.4%

Honeywell
found that heat pumps lost almost 50% of their efficiency after 20 years, even if typical "dust stop" filter were installed. In 20 years, a 12 SEER unit could degrade to a 6 SEER. This would double the energy cost!

Louisiana State University
and Gulf States Utility found consumers could save about $30 per month just by making sure that their air conditioning system was cleaned and serviced regularly.

HVAC manufacturer's
data shows a condensing unit with an SEER of 13 matched with an old air handler would decrease the SEER to 9.2, resulting in 30% less efficiency.
