Preformed prepaid maintenance on a Goodman split heat pump unit, model and serial number match in the system. Replaced filter and recommended it be replaced more often. This is for air quality purposes. Checked pressures and checked amp draws. Found that a hard start booster would benefit the condenser unit by dropping the amp load by 23 amps. Checked wiring connections cleaned coils, cleared drain line and added algecide treatment to drain pan. Recommended blue Tube Kit for growth prevention and homeowner will think about it for the future. All systematic components are working properly at this time.
