This is a do-it-yourself refrigerant kit for topping up mini-split and other R410A systems. It bundles two 28 oz cans of R410A with UV dye and leak sealant, a charging gauge, and an adapter, so one purchase covers the gas, the leak tracer and the pressure reading. The dye and sealant are already mixed into the refrigerant, which saves a separate injection step compared with buying plain R410A cans and a dye kit. It suits homeowners with a small or dual-head system that is at least half empty and who are comfortable charging in cooling mode. It is not a substitute for a licensed technician when a system has a major leak or is fully empty.

This is a two-bottle recharge kit for mini-split and other R410A air conditioning systems. It includes R410A refrigerant, a charging gauge and an adapter. The refrigerant also contains UV dye and sealant, so one kit covers recharging, leak detection and sealing.
Each bottle holds 28 oz, for 56 oz in total. The kit suits two small systems, a single larger system or a dual-head system, provided the systems are at least half empty. The amount needed varies with system size.
Always charge in cooling mode at 62 degrees, regardless of the outside or inside temperature. Recharging in heat mode involves high pressure and is dangerous. Under U.S. EPA regulations (Section 608), refrigerant may be added to or removed from an appliance only by an EPA-certified technician. The kit is sold for use by, or under the direct supervision of, a certified technician.
