Checked all major components on both units: Freon levels compressor , fan motor , capacitor, cleaned coils,, flushed drain lines,, replaced filters. Based on readings compressor on unit #2 is working hard and is noisy also the capacitor is reading lower that is rated . Recommend compressor overhaul kit to make compressor work smoother and extend compressor life. Also the capacitor for unit #1 is rusty and it creates resistance on electricity flow and need to be replaced too. Other than than everything looks good. Customer declined all the repairs for now .
