Found Lennox heat pump system completely void of refrigerant charge. There is a leak either on the indoor evaporator coil (air handler) or a leak on the outdoor condenser coil. The system is NOT under any manufacturer warranty and has had a long history of problems including compressor issues, refrigerant leaks, sealant added, drainage problems etc. Based on age and condition the ONLY option is for full system replacement. This is a multi-day job and will require dismantling the drop ceiling and will also require a jack/lift or crane to safely remove and remove the heat pump located on the roof. Chud will provide a replacement quote. See estimates for details. Approved estimate will require a 50% deposit prior to ordering any equipment.
