🛠️ HVAC Depot Pro Tip: Match Microfarads Exactly

Always replace a run capacitor with the exact microfarad rating specified by the manufacturer. While a higher voltage rating is acceptable, incorrect MFD values can cause overheating, inefficient motor operation, compressor damage, and premature component failure. Verify capacitor readings with a digital meter before replacing other HVAC components.
