Plan where 440 lb of refrigerant lands before it ships. Twenty cylinders is a store rather than a van load, so set aside a staging spot where they can sit secured and clear of work traffic. Confirm the delivery method and what the site needs to receive the consignment before the order moves. Stock at this volume also wants counting and issuing — crews drawing from one store should be signing gas out, not guessing what is left.
Storage is the real constraint at this tier. R-454B is mildly flammable, so check with your local fire authority how much the building is permitted to hold indoors before the order arrives. Cylinders stay upright, secured, capped and out of direct sun, in a ventilated space with ignition sources well clear. Keep the store away from pits and drains, since the vapour is heavier than air and will settle low.
This is the R-32 and R-1234yf blend that replaced R-410A in new splits, heat pumps, packaged units and rooftops built for mildly flammable refrigerants. It is not a drop-in for an existing R-410A system. Charge liquid only — the blend carries glide, so meter liquid in, throttle at the gauge set and weigh what goes in rather than trimming on pressure. Operating pressures sit in the R-410A class, so rated hoses, gauges and recovery gear apply. Recover into dedicated cylinders and never cross-fill.

These guys totally Rock
They can totally be trusted. This is not one of those fly-by-night stores. They might have some misspellings in their advertisements but that does not mean they're not honest. They just don't know how to spell. These guys are fantastic. I've been using them for years and they always have great product and great service.

A fantastic way to get your personal Freon for your home AC
Instead of paying 40 to $55 per pound for for your home air conditioning, keep your own on hand and they will use yours. A great way to save money especially with HOT summers and the need for a little Freon every year or two. A + A + A +

Showed up damaged
This is likely less of FreonWell's fault and more on the carrier, but it probably could have been packaged better to prevent it also. The tank showed up quickly and full, but the handles were extremely bent. The box was clearly dropped at some point. Surprisingly it doesn't seem like the valve took any damage so it's still usable

Was worried at first but actually came through.
Originally found it for $201. Extremely cheap and was worried it was a scam. Searched online and no reviews. But they did offer free 30 day free returns so I decided screw it. Luckily, it wasn’t a scam and refrigerant did show up at my front door :)
