                                WARNING
if your a/c condenser looks like this you're wasting your
money to cool your home.When fins on the condenser
deteriorate there is no heat dissipation causing high
energy bill,low cooling,blowing fuses and breakers
tripped. have your system evaluated  by a professional he
could save you a lot of money
              Understanding the a/c efficiency


Air-Source Heat Pump (ASHP):
An air-source unitary heat pump model consists of one or more factory-made assemblies which normally include
an indoor conditioning coil(s), compressor(s), and outdoor coil(s), including means to provide a heating function.
ASHPs shall provide the function of air heating with controlled temperature, and may include the functions of
air-cooling, air-circulation, air-cleaning, dehumidifying or humidifying.
Central Air Conditioner:
A central air conditioner model consists of one or more factory-made assemblies which normally include an
evaporator or cooling coil(s), compressor(s), and condenser(s). Central air conditioners provide the function of
air-cooling, and may include the functions of air-circulation, air-cleaning, dehumidifying or humidifying.
Heating Seasonal Performance Factor (HSPF):
This is a measure of a heat pump's energy efficiency over one heating season. It represents the total heating
output of a heat pump (including supplementary electric heat) during the normal heating season (in Btu) as
compared to the total electricity consumed (in watt-hours) during the same period. HSPF is based on tests
performed in accordance with AHRI 210/240 (formerly ARI Standard 210/240)1.
Seasonal Energy Efficiency Ratio (SEER):
This is a measure of equipment energy efficiency over the cooling season. It represents the total cooling of a
central air conditioner or heat pump (in Btu) during the normal cooling season as compared to the total electric
energy input (in watt-hours) consumed during the same period. SEER is based on tests performed in accordance
with AHRI 210/240 (formerly ARI Standard 210/240)1.
Energy Efficiency Ratio (EER):
This is a measure of the instantaneous energy efficiency of cooling equipment. EER is the steady-state rate of
heat energy removal (e.g., cooling capacity) by the equipment in Btuh divided by the steady-state rate of energy
input to the equipment in watts. This ratio is expressed in Btuh per watt (Btuh/watt). EER is based on tests
performed in accordance with AHRI 210/240 (formerly ARI Standard 210/240)
