The new HVAC unit must be the same size and capacity as the exiting units and have a factory warranty of at least 1 year for parts and 5 years for the compressor. The contractor must also provide new duct smoke detectors if required. The heat pump must be replaced with a unit requiring little modification of the existing duct system. The contractor must provide new programmable thermostats (5+2 day) if the existing thermostat isn’t compatible with new units.
Existing electrical disconnect must be removed by the contractor. New electrical disconnects must be provided and installed by the contractor. The contractor may use the existing electrical supply provided it is properly sized for the new unit. Contractor must provide and install all wiring, conduit, disconnects and breakers in accordance with local, state, and national codes.
The existing heat pump unit is a 2-ton roof-mounted Carrier model #50JZ-024-321TP (serial #4705G12279). The contractor may use the existing roof curb if it is compatible with the new unit. The contractor must ensure the level installation of the new heat pump.
The new heat pump must include a 2-stage electrical heat strip. Stage 1 must be 3 KW, stage 2 must be 4.5 KW. Stage 2 must be used only when heat pump is out of operation in normal temperature control mode. Stage 1 is for supplemental heat, stage 2 is for emergency heat.
