Energy Efficiency
The efficiency of Heating and
Air-Conditioning systems are measured by the SEER
(Seasonal Energy Efficiency Ratio) and EER (Energy
Efficiency Rating) rating which rates energy use for
different types and brands of equipment. SEER and EER
ratings are very similar to automobile miles per gallon
efficiency ratings. The higher the rating, the more
efficient the unit-and the more money saved in energy
costs. The majority of systems installed before 1992 are
rated at 10 SEER or below their efficiency continues to
drop with age.
This link to
www.hvacopcost.com shows the tremendous
energy savings of today's energy efficient Heating and
Air-Conditioning systems as compared to an old 8 SEER
system. When all of the components of your heating and
cooling system are properly combined in what is called a
"matched system," they work seamlessly together to
deliver maximum performance at a minimal cost, examined
air conditioning manufacturers' efficiencies versus the
actual efficiencies that resulted after installation and
found that 90% of newly installed units exhibited some
sort of energy-wasting, comfort-robbing problem,
therefore it is very important to only work with a
Contractor that utilizes the highest quality
installation techniques and train professional
installation specialists.
Additional significant
Heating and Air-Conditioning industry comfort and energy
related surveys1 also revealed the following
installation problems:
Duct Leakage (93%)
Poor indoor air
quality due to leaks in return air plenums.
Health and safety concerns related to air quality coming
out of supply vents
Drafts and uneven temperature due to duct leakage at
plenum and unions.
Above issue double air conditioning portion of the
utility bill and reduce family comfort
Unit Oversizing (47%)
Creates comfort
issues due to short run times not allowing enough
moisture removal
Air in sunlit & shaded rooms not having ample time to
mix via return air process
Larger Equipment in smaller home typically noise
concerns
Incorrect Refrigerant
Charge (54%)
Increased failure
rate due over pressurization or poor lubrication from
refrigerant oil
Reduced moisture removal creates an
uncomfortable home climate
Equipment typically noisier due to poor
lubrication from refrigerant oil
Uneven temperature in rooms
Could add as much as 17% to operating costs
Incorrect Air Flow (70%)
Uneven air flow
through system duct work creates uneven temperatures
Uneven air flow creates poor moisture control
Uneven air flow causes noisy grilles and
registers
Could add as much as 10% to operating costs
