Heat Pump/Condenser and Air Handler Replacement

1.0 - Scope of Work

The purpose of this project is to replace the existing outdoor heat pump and interior air handler at the Coffee Creek Fire Engine Office with a new 14 SEER heat pump/condenser and interior air handler. The outdoor unit is very old and has developed a hole and will develop more from rub spots in the bottom of the coil. This is due to age, vibration, and from snow accumulating on top of the unit.

The existing condenser/heat pump currently sits below a roof valley on the stations metal roof that receives a large amount of snow during Winter months. The intent of this unit replacement will be to move approximately 10 feet away from the roof line, out into the yard. This will eliminate snow buildup originating from the roof.

Note all new systems shall be of the same manufacturer or as recommended by manufacturer for system compatibility and warranty purposes.

Contractor shall furnish all material, labor, equipment, and transportation as required to accomplish the repairs. All demolition, disposal, and repairs described herein, for bringing the unit back into service are the responsibility of the Contractor.
