Chiller Replacement

Statement of Work (SOW) Project: Repair by replacing York Chiller

GENERAL INFORMATION

1.0 Scope of Work: Remove refrigerant and replace York chiller with a new chiller (Specs below), Leak check and charge to name plate on new Chiller.

2.0 Background: During a service call on the chiller, it was discovered that the multiple items on the York Chiller needed replacing as it is only running at half its capacity. The current chiller is costing us between $10,000 and $20,000 a year to keep running. With the upcoming hot weather, the chiller needs to be replaced or it will fail again. We currently have both a York and Trane Chiller on site that care of different sections of the building. Then new chiller will only replace the functions of the existing York Chiller.
