Homeowner had us out today because their system is not cooling. Upon arrival we noticed that there is a four year-old Lennox heat pump system in the home that is currently not running. We noticed that the emergency drain pan was full of water and the safety was engaged. We drained water and cleared drain. We checked the outdoor unit and noticed that the refrigerant pressures were slightly low and we also did a quick leak search on the coil and found a small leak. The coil is on back order for five weeks. We also noticed that the 35/5 capacitor was failing and out of range And the outdoor coil needed to be cleaned.
