Claim:
1. A method for monitoring and controlling an energy demand by an HVAC system including a plurality of powered components in communication with an electrical grid, the method comprising the steps of: receiving, in a control device in operable connection with the HVAC system and having a computer processor and a computer memory, values of one or more parameters related to performance of the plurality of powered components being powered by the electrical grid; comparing, using the computer processor of the control device, the received values with corresponding predetermined threshold values stored in the computer memory of the control device for each of the plurality of powered components; determining, using the computer processor of the control device, overloading of the electrical grid by a powered component among the plurality of powered components based on respective values of one or more parameters being less than the corresponding predetermined threshold values for the powered component; selectively controlling, using the computer processor of the control device, the operation of the powered component based on the electrical grid determined to be overloaded without disrupting operation of the remaining plurality of powered components being powered by the electrical grid; and determining a power shortage in the electrical grid via a central server, determining a priority of the HVAC system based upon the values determined for that HVAC system relative to other HVAC systems using the electrical grid, and turning off a compressor of the HVAC system in the event of a power shortage based upon the priority determined.
