Removed old rusted out filter dryer that caused the refrigerant to leak out causing outdoor unit to short cycle on and off, dry fitted new biflow filter dryer for a heat pump and ran nitrogen through the system while brazing the new filter dryer in place, pressure tested system with nitrogen at 300psi and let seat for a while to help dry out any moisture, vacuumed system to desired dehydration levels and recharged system with 8 pounds of refrigerant to manufactures specifications tested both sides of the system in cooling and heating modes, condenser motor starts hard but than it gets quiet, could be a potential issue down the road but will address later on when it becomes an issue as I was informed, everything is working properly at my departure, thank you for letting me work on your system and thank you for using total air as your hvac company.
