Completed a 3 system Homecare. We flushed drain lines, changed filters and checked system operation to determine system condition, performance and safety. The downstairs unit has a breached heat exchanger and is 20 years old. We spoke about the cost for repairs and she wants to consult her husband before addressing long term solutions. We completed 2 blower cleanings, 2 condenser coil cleanings, fixed the sediment trap for the main floor, replaced the drain line upstairs, insulated both linesets and replaced the run capacitor upstairs. Systems are fully operational upon completion. Call complete.
