Upon arrival found system somewhat cooling. Checked inside unit and found everything operational. Noticed that the home needs more attic insulation. Checked outdoor unit and found pressures low, gave recommendations on what we can do next. Homeowner wanted to recharge system. Added 4lbs of 410-a to system to bring pressures up. Recommended a leak search and refrigerant had the potential to leak back out. System is now cooling properly at this time.
