Q: Will cooling performance improve if compressor speed or capacity is increased?

A: Cooling performance could improve by increasing compressor speed or capacity; however, HVAC system capacity is not based solely on compressor capacity. Control algorithms, evaporator and condenser sizing, as well as a host of other factors contribute to system capacity, so simply speeding up your compressor or upgrading to a higher-capacity compressor will not necessarily increase your actual system performance. Please consider consulting an aftermarket HVAC systems company if you need help in upgrading your system.
