Paige Air conditioning repair Upon my arrival I performed a 6 month checkup on 1 heat pump system. Flushed and treated the water removal system, cleaned the condenser coil using water, removed the pine needles from inside the condenser, cleaned and treated the electrical cabinet then verified system safety and performance. I found the system performing to manufacture specifications at this time but there is bacterial growth present inside the air handler. I spoke with the customer about my concerns and she is unsure whether or not she will be keeping the home so does not wish to have Solaris installed. She will take a look at options for cleaning of the system and possibly consider going that route.
