Why replace the HVAC system

• Systems antiquated, unreliable, and components are failing

• Outside technical expertise required to manage controls

• Can not adequately control temperature and humidity – impacts • Can not adequately control temperature and humidity – impacts piano, organ, and church interior

• Single mode system – either heat or air conditioning

• Poor ventilation control

• Controls are mechanical – no central monitoring or control

• System is not very effective or efficient4
