Tech checked both systems in heat and emergency heat mode and SC mode. I checked the refrigerant pressures. I checked the amps on the strip heat. I replace the breaker for the upstairs system (air handler) due to it being oversized. The breaker for the basement/2nd floor Air handler is undersized; homeowner declined to have me upgrade the breaker to the correct size. I checked the zoning. I checked both blower motors, compressors and condenser fan motors and all three thermostats. I flushed the upstairs drain line with enzymes, water and clean out tablets (drain into washer plumbing stack). I checked both contactors and capacitors on both outdoor units. I replaced blower motor capacitor for the basement/mainfloor system; with homeowners permission. The homeowner signed up for the homecare renewal. Both hvac systems were operating at the time of service call.
