Upon my arrival Paige I did AC Maintenance I evaluated 1 heat pump system. I verified system safety and performance is to manufacture specifications. Flushed and treated the water removal system. Cleaned the electrical cabinet and washed unit using water. Found the voltage enhancement system low for the outdoor unit. Recommend replacing, this is also covered by the 10yr p&l. I was approved to replace the voltage enhancement system for the outdoor unit then I did a performance and safety testing. This system is working properly.
