My new carrier came with Chinese capacitors, so that meth out window on new units. I bet 90% made in China or elsewhere over seas? My last TRANE had Chinese capacitor over 9 years old. Capacitors can easily be checked with multimeter (Utube). You are right know way knowing if Freon low unless if not cooling efficient. They also check cooling efficiency and heat side in fall. Some homeowners can do most things on annual tune up. The problem I have some businesses look to scam non savvy customers when they get their foot inside house. So my advise find company that’s earned its trust. I prefer munns out of the other two I had. One company I wouldn’t let them change my water hose.
