Do not block supply or return air grills.

cycling Condenser Air
Most condenser discharge
air vertically and draw air into the bottom or sides. Overhangs, roofs, fences
or shrubs can block air discharge and be drawn back into the condenser. This increases
the compressor amperage and temperature.
Belt driven systems require occasionally
adjustment or fan belt replacement. Loose fan belts will slip on the motor pulley.
Wearing the V groove of the pulley wall and slow the fan and reduce the air flow.
Condensers are design to work at
95F or higher. In cooler temperature below 70F, the mechanical refrigeration will
lose efficiency. By turning off condenser fan or reducing the speed of the fan
keeps the condenser pressure steady.
When the outdoor air is below the room
temperature it can be used for cooling. Why pay for the compressor operation when
you don't have to.
Automatically turn the thermostat set
point up a few degrees during unoccupied periods will reduce power consumption

Bigger is not better. Over sized equipment will
short cycle and use more power. Select equipment according to the heat gain for
the building. Multi-stage or variable speed equipment are more efficient and closely
match the current load.
