R407C 7.5 LBS Refrigerant

No, and this is the most common misunderstanding about it. R-407C matches R-22’s properties more closely than any of the common alternatives, but it requires POE lubricant — so the system has to be converted off mineral oil first. That makes it a planned job rather than a quick swap. If you need to avoid the oil change, look at R-421A, R-422D, R-427A or R-438A instead.

Enough to change how you read the system. The refrigerant boils and condenses across a temperature range rather than at a single point, so superheat must be calculated from the dew point and subcooling from the bubble point. Reading it from one saturation figure is the classic source of a mischarged R-407C system — see our guide on glide.

No. Because of the glide, drawing vapour changes the composition of what is left in the cylinder. Charge as a liquid, and if a system needs topping up after a leak it is usually better practice to recover and recharge than to add to an unknown composition.

Closer performance to R-22, at the cost of the lubricant change. Shops choose it where capacity and efficiency after conversion matter enough to justify the extra work — typically larger residential and light commercial jobs. See R-407C as an R-22 retrofit.

Shipping is free on every order. Transit time depends on your location and the size of the order — a single cylinder ships as a parcel, while quarter, half and full pallets move by freight and take longer to arrive. Returns are free.
