Upon my arrival, I performed a six month check up on one straight, cool system. I flushed and treated the water removal system, wash the condenser coil using water, cleaned and treated the electrical cabinet with electrical insecticide, then verify systems safety and performance. I found the voltage enhancement system to be lower than manufacturer recommends, the voltage distribution system is be becoming chard/pitted, and the systems startup amps are higher than manufacture recommends. I recommend having the voltage enhancement system, the voltage distribution system replaced and installing a performance enhancement system for a longer compressor life. Due to the husband going back to bed the wife asked that I email the options over for them to review.
