The HVAC Service Assistant is changing the HVAC Service Industry. The tool provides expert diagnostic analysis of HVAC equipment, automating the detection, diagnosis and reporting of problems. By calculating the efficiency and capacity of units, the HVAC Service Assistant produces reports detailing energy savings.

		While connected to a commercial and residential split and packaged air conditioning system, the HVAC Service Assistant records 6 key measurements from the units Suction pressure Liquid pressure Suction temperature Liquid temperature Ambient temperature Return air dry-bulb and wet-bulb temperature Supply air dry-bulb and wet-bulb temperature Calculated performance indices are used to identify faults in the unit.
From the resulting diagnostic messages, technicians are able to produce better running equipment.

The result is:

• Enhanced reliability
• Additional cooling capacity
• Energy efficiency
• Reporting that documents these gains and allows managers, contractors and technicians to understand where the opportunities are and how to achieve the benefits. Click here to view a sample report.

The measurements also enable the HVAC Service Assistant to calculate the Efficiency Index (EI) and Capacity Index (CI) providing a snapshot of the overall health of a unit.With the EI and CI recorded we are able to quantify the energy cost of operating at reduced efficiency or capacity.

Field Diagnostics processes, protocols and reporting build feedback into every step of the maintenance and repair process. Using the HVAC Service Assistant provides objective information to technicians on the rooftop, to their service managers monitoring the work that is being performed, and to end users and facility owners who want to know the true status of their equipment. With the data transmitted from the databases housed on Field Diagnostics servers and accessed via the Online service, reports are generated to address:

• How efficiently units are running
• How to prioritize retro-commissioning or tune-up measures
• How much lower the electric usage will be when the tune-up is completed

The result is that we can measure the impact of our service and maintenance expenditures and feel comfortable we are making good decisions. We can feel even more certain that we are delivering good value to our customers and effectively differentiating ourselves from competitors.
