I am a highly skilled home service professional. I recently completed a job on a 2023 ton road package heat pump unit. The unit was not cooling properly, so I performed a thorough inspection and found that the evaporator coil was dirty and clogged with debris. I cleaned the coil and replaced the air filter, which resolved the issue. I also checked the refrigerant levels and added more if necessary. Finally, I performed a system performance test to ensure that the unit was operating at peak efficiency.
