Heat check completed on one upflow Carrier heat pump and one mini split. I flushed and cleaned both condensation drain lines. I cleaned both condensing coils. All mechanical and electrical components were checked. I found that the outdoor torque booster on the Carrier heat pump was failing. Homeowner chose to replace the torque booster today. I replaced the torque booster and function tested the system. No other major issues were found. Everything is working at completion of service.
