Mobile Handheld PDA Software & HVAC Service Technicians

The poor HVAC service technician didn't see it coming. My wife tried to warn him. She said, "Don't answer any of his questions!" It was too late.

• Kevin -"What have you got there on the clipboard."


• Unsuspecting HVAC service technician -"This is a work order form."


• "How do you know where to go for your next job"


• "I call Pam at the office. Problem is my Nextel phone takes 10 minutes to connect to the office...I hate it. Sometimes I use my own personal phone to call her."


• "What does Pam do?"


• "She talks to all the service technicians and dispatches all the work. She tries to keep track of where all the service technicians are and what they should be doing, and where they should go next."


• "What happens if Pam elopes to Las Vegas with a circus clown?"


• "We would just close down the shop and lock the door. She is critical to our business...I call her 5-7 times a day to have her look up archived work orders so I know what previous work has been done on a furnace or air conditioner, and what parts were replaced."


• "How long do you spend on the phone with Pam for each of those 5-7 times a day?


• "About 10 minutes each time."


• "Do all the HVAC service technicians call her for information on archived work orders?"


• "Yup...she also dispatches all work orders to us by calling us on the phone and reading us the address of our next jobs and instructing us on what to do. We stop working or driving and write down all the information for the next job."
• "How does the work order information get entered into the accounting software?"
• "Another person enters the data into the accounting software each day."

At this point -my wife stepped in between us and pushed the HVAC service technician out the door and he escaped!!!"

OK...some math and ROI considerations:

• 7 HVAC service technicians
• 60 minutes/day/HVAC service technician on the phone with Pam looking up archived work orders
• 20 minutes/day/HVAC service technician on the phone with Pam writing down new work orders
• 10 minutes/day/HVAC service technician waiting on the Nextel phone system to work
• Pam spends 8 hours a day dispatching and talking to HVAC service technicians on the phone

If my numbers are correct that would equal 18.3 hours per day that the HVAC company is wasting on tasks that could be automated and mobilized by using a mobile handheld PDA work order software application (from MobileDataforce) synchronized with the work order management system in the office. If you multiply 18.3 by $20/hour you have $366. Now multiply $366 by 22 work days in the average month and you have $8,052. Now multiply $8,052 by 12 months and you have $96,624.

The total cost of a mobile work order management system running on ruggedized handheld computers that synchronize wirelessly with the office dispatch system would be a fraction of this expense. Plus I did not even include the cost of entering the data into the accounting system.
