No cooling, found system off by float, switch being tripped due to clogged drain. Did a complete evaluation of AC system. Found biological growth buildup inside air handler and drain, compressor has high startup amps, and system is low on refrigerant. Gave client solutions for issues with system, however, system is six years old and out of warranty, recommended replacing AC system due to age and cost of repairs. Client decided to go with replacement. Installing a new 4 ton carrier heat pump on Wednesday, October 8. Client paid 50% deposit. Flushed out drain and topped system off with refrigerant to get them cooling for now until we can do the install
