Upon my arrival in Paige I did AC Repair. performed a 6 month checkup on 1 straight cool system and 1 heat pump. Flushed and treated both water removal systems, washed condenser coils with water, cleaned and treated electrical cabinet with electrical insecticide then verified systems safety and performance. I found both systems to be operating within manufacture specifications at this time. System #1 has started to develop some bacterial growth. I spoke with the customer about this and she is interested in installing Solaris but would like to wait until the next checkup. Customer does still want the options emailed over. I would like to be the one scheduled on the next checkup. Renewed maintenance contracts while on site.
