Capacitors for hvac & heat pumps

About capacitors for hvac & heat pumps

Heat pumps, air conditioners and refrigeration condensers use run capacitors to keep the fan and compressor motors turning smoothly, sometimes a single dual run capacitor that handles both at once. Values typically fall in the 5-80µF range, and most factory parts are rated 370V or 440V. A 450V capacitor is a safe replacement for a 370V or 440V one (the higher voltage rating is a ceiling, not a target), so long as the µF matches. Read the µF and voltage printed on the side of your old capacitor: if you see two figures like 45+5µF, that's a dual-run (CBB65) capacitor, which we don't currently stock: contact us before ordering, because our single-value run caps only replace single-value originals.
