Tech cleaned system thoroughly, water was cut off during service by city due to a busted pipe. Will have to come back out to wash coils on outdoor unit. Customer requests to have same tech come back out. Tech found no challenges with system, added access door for indoor coil on return box as well as union on drain line. Customer invested in one system PSA for one year two visits. Tech collected $403.52 in total by check for todays visit. System is operating properly.
