Arrived to find all working but air not blowing so hard out of vents now. Investigated system to find Freon pressure to spec but temp split was only 7 degrees. Found thermostat calling for emergency Heat kit while calling for cool modes to be ran and forcing blower motor to low speed and running 5kw Heat kit. Replaced thermostat and system is now cooling with a 20 degree temp split and has dropped 5 degrees while on site. Payed by check please mail invoice of today and yesterday to PO Box 68
