Three system tune update performed today. All systems are heat pumps with air handlers installed in 2020. All electrical connections are tight with no corrosion. Blower wheels and evaporator coils are clean. Customer states that there are high humidity levels in the home. Technician found that the main system had several air leaks in the air handler. Sealed up the air handler and believe the issue is fixed. The master bedroom unit had the TXV bulb on the bottom of the vapor line. Moved the bulb to the top and refrigerant readings improved. With proper refrigerant readings the humidity levels should now go down. Biological growth is present in all of the systems. Suggest adding indoor air quality products to sterilize the systems and the air. All amp readings are within tolerance. All refrigerant levels are acceptable. All three outdoor units were washed.
