No cool. Downstairs unit drain line backed up. Drain lines are all built up with debris. I cleared the drain with pressure at no charge today. Home owner authorized drain solve treatment on all four main house drains. Due to weather and lack of supplies this will have to be scheduled next week. Home owner wants to purchase 4 oxidizers to add to her existing pure air system. I do not have a stand alone task for this so we will have to give estimate Tuesday morning. System cooling at this time.
