• Larger air conditioning systems use larger compressors and blower motors, so they use more electrical power to operate • Electrical installation costs are higher because more electrical power requires that larger conductors be run to the unit location • Larger cooling equipment will cool the space faster. This results in more frequent system starts and stops, increasing the system’s power consumption • Larger cooling equipment will cool the space faster. This results in more system off- time, decreasing the dehumidification effect that air conditioning systems have on the occupied space • Decreased dehumidification leads to higher relative humidity in the occupied space. This leads to an increase in the possibility of mold growth in the space • Mold growth in the space puts you, the contractor, at increased risk of litigation as a result of mold-related illness • Larger equipment costs more to manufacture, to keep in inventory and to ship • The manufacturing of larger equipment requires the use of more natural resources,
