I was called to check on a 2019 2 1/2 ton Lennox package heat pump system. The customer reported that the system was not cooling properly. I arrived at the customer's home and performed a thorough inspection of the system. I found that the evaporator coil was dirty and clogged with debris. I cleaned the coil and the system started cooling properly. The customer was happy with the service and thanked me for my help.
