Today Rodrigo and I arrived and met with Mr Santiago. We immediately verified customers concern of no cool air, we found all to be proper within the attic unit. We placed system into test mode and inspected outside. We verified system power and verified voltage enhancement system, next we began monitoring operational pressures. We immediately noticed our main refrigerant pressure control is faulted and not performing accordingly. After updating customer and inquiring of parts customer gave approval for repair. Today we have ordered the replacement parts, upon arrival dispatch team will be contacting customer to have repair completed. Upon departure we advised customer leave unit off, if they happen to need heating they are aware to use EM Heat.
