| 01 | | THE FAILURE MODE |
| |
| What the next step meets is an installed base. DOE's federal purchasing guidance assumes an average residential central air conditioner life of 18 to 25 years depending on configuration [2]. Equipment sold before the 2025 refrigerant transition will still be running through the 2029 reduction and well past it, and servicing it draws on the same shrinking pool of virgin material. |
| The allowance market is already repricing access. Consumption allowance transfers rose from roughly 6.5 percent of general pool allowances in 2023 to about 12.0 percent in 2025, even as the total number of allowances fell under the phasedown [1]. Participants in the transfer market went from 15 or fewer in 2022 and 2023 to more than 30 transferring allowances away in 2025 [1]. |
| The price signal has not followed. EPA observed that standard contractor-sized cylinders of R-410A were selling at one-third of the expected cost in 2024, and noted that some importers may have found it more advantageous to transfer allowances than to import [1]. A scarcity on a schedule is not the same as a scarcity now. |

| 02 | | YOUR END / THEIR END |
| |
YOUR END HOUSEHOLD The household's exposure sits in a machine with a long life and a dated fill. DOE's purchasing guidance puts the annual energy cost of a residential central air conditioner at $270 to $473 depending on configuration, assumes 18 to 25 years of service life, and treats an ENERGY STAR unit as life cycle cost-effective at a price premium of up to $869 to $1,853 above the baseline model in 2023 dollars [2]. Replacing early moves the house onto the current refrigerant generation while that generation is the one being stocked. Two limits. Those figures price the efficiency increment rather than the installation, and they are national averages rather than a quote. And the case for moving early rests on a shortage that has not yet appeared in refrigerant pricing [1], which makes early replacement capital committed several years ahead of the risk it answers.

THEIR END COMPANY-REPORTED Watsco (NYSE: WSO) is the distribution layer between the manufacturers and the contractor who does that replacement. The 2025 transition to systems using A2L refrigerants affected virtually all domestic HVAC equipment products it sold, across 650 domestic locations [3]. In the second quarter of 2026 sales were $2.10 billion, up 2 percent, with domestic residential HVAC equipment sales up 5 percent on 2 percent unit volume growth and 2 percent higher average selling prices [3]. The counterweight is that handling a transition is not the same as being paid for one. Gross profit fell 4 percent to $579 million and gross margin narrowed to 27.5 percent from 29.3 percent, with about 130 basis points of that attributed to the prior year's comparison and other A2L-related effects [3]. The regulatory change moved through the channel and left the margin lower. POSITION / CAPACITY / RISK |

| 03 | | THE LEAD TIME |
| |
| 43,543 metric tons of regulated HFCs were imported for consumptive use in 2025, down from 53,715 metric tons in 2022, per EPA's draft program analysis published July 2026 [1]. Imports from China fell by about half between 2024 and 2025 as sourcing shifted toward the United Arab Emirates and India [1], so the import share of supply now rests on a different set of origins. |
| |
| 04 | | THE TWO DECISIONS |
| |
| The household decision is whether to retire a working air conditioner years early, at an efficiency premium DOE puts at up to $1,853 plus installation, to get ahead of a reduction step scheduled for 2029. The exposure decision is a distributor whose volumes recovered after the last transition while its margin did not. The premise weakens materially if EPA's allocation methodology for 2029 onward, still unwritten, arrives with enough reclaimed and recovered supply to keep servicing costs flat, or if R-410A continues to sell near the levels EPA observed in 2024, in which case the installed base runs out its life without the shortage arriving. |
