We are part of the 10% that do It right!
The North Carolina Alternative Energy Corporation, a non-profit organization, examined air conditioning manufacturers’ efficiencies versus the actual efficiencies that resulted after installation. They found that 90% of the units tested exhibited some sort of energy-wasting, comfort-robbing problem.
Duct Leakage (93%)
- Poor indoor air quality
- Health and safety concerns
- Drafts and uneven temperature
- May DOUBLE the HVAC portion of the energy bill
Oversizing (47%)
- Doesn’t run enough to wring out moisture
- Air in sunlit & shaded rooms does not mix
- Equipment is typically noisier
- Shorter equipment life
Incorrect Refrigerant Charge (54%)
- Increased failure rate
- Reduced moisture removal
- Equipment is typically noisier
- Uneven temperature
- Could add as much as 17% to operating costs
Incorrect Air Flow (70%)
- Uneven temperatures
- Poor moisture control
- Noisy grilles and registers
- Could add as much as 10% to operating costs
Other significant HVAC industry comfort and energy-related surveys revealed Texas A&M University, Louisiana State University & Gulf State Utility, Lakeland Electric & Water, Pacific Gas & Electric, American Council for an Energy Efficient Economy, etc.
These studies address at least one problem a poor installation plays on comfort or energy costs. Occurrences have been averaged.
