On May 21, 2026, the U.S. EPA issued a final rule lifting the January 1, 2026 prohibition on installing new R-410A residential and light commercial equipment. Industry groups estimate the rule change could add roughly USD 13 billion in costs to the HVACR sector, because it expands demand for refrigerants whose supply is still phasing down under the AIM Act statutory schedule.
You are now pricing into two refrigerant generations at once. R-454B and R-32 catalogues have no historical market pricing benchmark, because the generation did not exist three years ago. R-410A inventory whose value seemed settled in March just shifted on a Wednesday morning.
R-410A prices are already up 40 to 70 percent from 2022 levels. The 2029 phasedown step, which cuts allowances from 60% to 30% of baseline, is the steepest single reduction in the schedule and still ahead.
And if you have stood up a D2C channel alongside your dealer network in the last three years, you now have two pricing systems that do not talk to each other. Your dealer can see your own SKUs priced differently on your own website within an hour of any update.
Your annual pricing cycle gives you no answer to any of this.
The answer lives inside the price waterfall.
The price waterfall is the path a part takes from list to pocket. List, distributor or dealer discount, channel-specific adjustment, customer rebate, off-invoice items, freight, returns, warranty allowance. Each step is small. Each is invisible to the next one upstream. Most HVAC OEMs see two numbers, the top (list) and the bottom (gross margin at year-end). Everything between is dark.
Right now, that dark stretch is under unusual stress:
Four pressures, one waterfall. The HVAC OEMs that hold margin through the rest of the transition are the ones that can actually see it.
You probably recognise at least three of these:
This is the trap most HVAC pricing teams underestimate. The D2C channel is not just a new sales motion. It is a public pricing record. Once you have stood up your own ecommerce site, every price you set is visible to your dealer network within an hour. If the governance layer is missing, your direct-to-consumer site will post a price that your best dealer cannot match. The dealer's response is not anger, it is quiet defection: the next time a homeowner asks for an installer recommendation, your equipment is not the recommendation. This is not a CRM problem. It is a pricing problem. And the legacy HVAC pricing process has no answer for it.
A single SKU. A new-generation scroll compressor for R-454B residential and light commercial systems. It ships across heat pumps, packaged units, and split systems. There is no historical pricing benchmark on this generation, because the refrigerant transition is too recent. The same pattern shows up on EC motor assemblies, microchannel coils, and any new-generation part where the market is still finding its price.
The list price below is an example value. The structure is what happens in real portfolios every day.
More than a third of the value disappears between list and pocket. Around eleven to thirteen percentage points of that is recoverable: the channel-conflict adjustment that should have been built into governance before the conflict appeared, the flat rebate on a part with limited substitution risk, the warranty allowance set wider than the new-generation failure data yet justifies.
One percent on this single SKU is roughly USD 18 per unit. Across an HVAC portfolio of tens of thousands of active SKUs across multiple refrigerant generations and channel types, the recoverable margin compounds quickly in a market that is not growing fast enough to absorb it otherwise.
Whatever you build or buy, three capabilities have to work together. Any one of them in isolation will not move pocket margin.
Without those three, HVAC pricing is one regulatory event away from carrying losses the new equipment cycle cannot offset.
MP ONE™ is one answer to this. Whatever platform you put behind it, the shift in day-to-day pricing work looks the same:
That is the shift. One way to deliver it, and the way MP ONE does, is by unifying three capabilities most HVAC OEMs currently have scattered across systems and teams. The Intelligence Engine watches the market continuously. The Decision Engine applies pricing logic at the SKU and channel level. The Performance Engine tracks what actually realises in pocket. One platform, one waterfall, one source of truth.
You do not have another full pricing cycle to figure this out. The AIM Act phasedown is not pausing. The next regulatory reconsideration is not pausing. The dealer who is comparing your D2C site to your wholesale list price is not getting more patient.
Every quarter your competitor runs on a continuous waterfall with channel-specific governance and you run on an annual one with a uniform discount tree, they take margin you did not know you had.
The HVAC OEMs that hold margin through the refrigerant transition and the D2C shift will have done one thing in common: they will have killed the idea that channel pricing manages itself. Their D2C site will not have found an OEM price lower than the dealer's net, not because someone caught the conflict, but because the governance logic was built before the problem appeared. The OEMs that do not will spend years explaining at the board why their own channel strategy cost them their strongest dealer relationships.
