Frequently Asked Questions

Yes. Per 40 CFR §82.154, all HFC sales require EPA Section 608 certification (Type I, II, III, or Universal), Section 609 for mobile AC work, or registered wholesaler-resale status. You'll provide your cert number at checkout.

No. EPA regulations prohibit the sale of regulated refrigerants to anyone without Section 608 or 609 certification. There is no legal DIY pathway for R-410A, R-22, R-134A, R-404A, R-454B, R-32, R-407C, or R-448A. A homeowner who needs an AC recharge should hire a certified technician.

Yes, for servicing existing equipment. Under the AIM Act, only the manufacture of new R-410A residential split systems is restricted (starting 2025). EPA Section 608-certified technicians may continue to purchase R-410A to service the millions of existing systems in the field.

Yes, for servicing existing equipment. Production and import of new R-22 was banned on January 1, 2020 under Montreal Protocol rules, but existing stock (virgin and reclaimed) remains legal to buy, sell, and use by certified technicians.

Section 608 covers stationary HVAC and refrigeration (residential, commercial). Four certification types: I (small appliances), II (high-pressure), III (low-pressure), Universal (all three). Section 609 covers mobile automotive AC only (R-134A, R-1234yf). A Universal 608 does not automatically include 609 - they're separate certifications.

Federal Section 608 certifications do not expire. A few states have their own renewal requirements. Section 609 also does not federally expire.

Per §82.154, we retain your signed certification form and sale records for three years, available to EPA on audit. Your certification number is stored on your account for convenient reuse.

All regulated refrigerants: CFCs, HCFCs (R-22, R-123), HFCs (R-410A, R-134A, R-404A, R-407C, R-448A, R-449A, R-452A), HFO blends (R-454B), and single-component HFCs (R-32). HFO pure (R-1234yf) is restricted by most suppliers.

100% virgin, factory-sealed. We do not sell reclaimed product. Every cylinder is AHRI-700 compliant and sourced directly from Honeywell, Chemours, or American manufacturers.

R-454B has a 78% lower Global Warming Potential (466 vs 2,088) and is classified A2L (mildly flammable). The two are NOT interchangeable - R-454B requires equipment specifically rated for A2L service.

No. R-454B is not a drop-in for R-410A. Using it in R-410A equipment voids warranties, violates safety codes, and creates a fire hazard. R-454B only belongs in equipment certified for A2L refrigerants.

R-32 is a single-component HFC with a GWP of 675. R-454B is a blend of R-32 and R-1234yf with a GWP of 466. Both are A2L. R-32 dominates ductless mini-splits globally; R-454B dominates US ducted splits in 2025+.

Most common replacements: R-448A (Solstice N40), R-449A (Opteon XP40), and R-452A. R-448A is the most widely adopted in US supermarket applications due to lower GWP and wide OEM support.

R-407C is an HFC blend commonly used as an R-22 retrofit in existing residential and commercial AC systems, heat pumps, and chillers. It's not typically specified for new installations.

Primary: Honeywell (Solstice 454B, Solstice N40), Chemours (Opteon line), and American-branded virgin HFCs. All cylinders are factory-sealed, never reclaimed, and AHRI-700 verified.

Automotive R-134A is being replaced by R-1234yf in new vehicles since roughly 2015. But R-134A remains fully legal to purchase and use for servicing existing vehicles and stationary equipment. It is not phased out.

Not currently. We focus on HFCs and A2L blends for HVAC and commercial refrigeration. For R-1234yf mobile AC applications, we recommend contacting a mobile-AC specialist distributor.

DOT-39 disposable cylinders: recycle per local hazmat rules or return to us. DOT-4BW/4BA refillable: return for recertification and refill. Never vent residual refrigerant to 'empty' a cylinder - it's illegal under the Clean Air Act.

A2L refrigerants are classified as mildly flammable with low burning velocity. They are safe when handled by properly trained technicians with A2L-rated equipment per ASHRAE 15 and UL 60335-2-40.

Yes. Recovery machines, cylinders, and leak detectors must be specifically A2L-rated. Do not use R-410A recovery equipment on A2L refrigerants - it's a code violation and creates a genuine liability risk.

Upright, secured, in a dry ventilated area below 125°F, out of direct sunlight. A2L cylinders should be segregated from ignition sources and stored with appropriate ventilation. Always use valve caps when the cylinder is not in use.

Below 125°F. Houston summer service trucks routinely exceed this - insulated hazmat storage boxes or climate-controlled truck compartments are recommended. Cylinder pressure rises rapidly above 125°F and exceeds safe limits around 150°F.

Yes, under 1,001 lb hazmat threshold (where a commercial driver hazmat endorsement is required). Shipping papers and SDS must be in the vehicle. Secure cylinders upright; never loose.
