2 system maintenance, 2023,2014 electric heat, 410a, filters are good, lines are clear, washed units off, but do need some weeding done around unit, vines are growing into the cages. Pressures are good, capacitor on upstairs 2.5 ton 2014 is low on both fan and compressor, fan on same system is running at full load amps. Would redo lineset armorflex, has degraded over the years, would add compressor saver to both units. Insulation is recommended as well, will definitely help with cooling the house in summertime and keep warm in winter.
