Upon arrival homeowner informed me that system continuously runs when and won’t drop temp below 77-78. Found unit to be low on 410A. Did leak check at condenser and evap coil. No signs of leak nor did I detect a leak with leak detector. Homeowner decided he’d like to recharge system to manufacture standards.-Recharged system with 2.5 lbs of 410A Temperature split and psi levels check out good after recharge. System now operating properly at manufacturer standards at time of departure.
