( The fun part of economizing)
Fun questions
• “Can I install an economizer on a 3.5 ton?”
• “What if the RTU is on the ground?”
• “What is a T87F Thermostat?”(the round one)
• “Can I steal my competitors customers?”
• “Why can’t I install economizers on Split Systems?”

Issues found at post inspection• 46 units have had post inspection
• All post inspections were done in AM and units were all calling for economizing, except one
• 2 units have had repairable issues, and where repaired at time of Post install
• One add on economizer had defective common wire and was repaired
• One economizer on York unit did not fit correctly over return and had to be corrected
Next steps
