Job Checkin

Found unit locked out at outdoor unit on cycling off pressure switch. Found that in cooling mode system will run ok but in heating mode head pressure is pushing over 600 psi. Found that on the exsisting duct work there is only 5 6” supplies. And on the return there is a 12” and a 10” return flex which pulls in the cavity of 2x4 walls. With the new system the duct work needs to be altered to be able to get the correct air flow in heating mode. Went over my findings with the office and told vien we will be getting back to her as far as a solution to the duct work. Liquid line on refrigeration side is also 1/4” will look into weather this needs up sized to 3/8” or not. Also performed 6 month inspection.
