Upon arrival I found the thermostats were turned off. Everett stated he did that after the louvers on each air handler stopped when it should have been cooling. Went outside and checked condenser and found that the compressor was off on high pressure. The refrigerant charge was weighed in when we installed the condenser so I knew it was not overcharged. I verified that the condenser coil was clear. Cycle power and system came on and was Cooling properly. I advised Everett what to do if it does it again. No charge for Diagnostic today because of all of the problems that Everett has gone through with this system.
