ONE PROBLEM, IN DETAIL

WHAT BREAKS

WHERE THE MONEY GOES.

The refrigerant whipsaw (2025-2026's cost story, start to finish)

The AIM Act's HFC phasedown ended new R-410A equipment production, pushing the market to mildly flammable A2L refrigerants (R-454B, R-32). Then the transition broke: R-454B cylinder shortages through 2025, Honeywell's 42 percent surcharge plus a $4-per-pound base increase, Chemours adding $2.85 per pound, cylinders reported at $650 to $700 (versus roughly $350 for R-32), and some markets seeing cylinder prices multiply several-fold. A2L equipment carries 15 to 20 percent higher manufacturing cost (leak sensors, revised charge limits), landing 8 to 10 percent higher at the customer. Then the regulator blinked: EPA declared the install deadline a low enforcement priority in December 2025 and, in a final rule effective July 27, 2026, removed it, so pre-2025 R-410A units can now be installed "until supply runs out" (New York's state cutoff excepted). Contractors who priced, stocked, tooled, and certified against one regime watched it rewrite itself twice in eighteen months.

WHAT THE NUMBERS SAY

THE COST, SOURCED.

Sourced anchors

Honeywell 42 percent surcharge + $4/lb; Chemours +$2.85/lb; cylinder pricing spreads; +15-20 percent equipment manufacturing / +8-10 percent finished; EPA reversal timeline (proposed Sept 2025, low-priority Dec 23, 2025, final rule May 26, 2026, effective July 27, 2026); 81.3 percent of certified heat-pump models now list R-454B.

WHAT THIS TRADE SHOULD EARN

THE NUMBER TO MEASURE IT AGAINST.

HVAC contractors run about % net profit at $1M to $5M, rising to roughly 10% at $5M to $10M. The CFOS target at $1M to $5M is11%, set at 10 percent before taxes or 3.5 points better than your trade's average at your revenue, whichever is higher. A problem like this one lives in the distance between those two figures rather than in a loss on any single job.

Gross margin over the same bands runs % to 25%, against a CFOS target of 11%.

COMMON QUESTIONS

FREQUENTLY ASKED.

How did the A2L refrigerant transition hit HVAC costs?

From every direction: R-454B shortages and producer surcharges (42 percent plus per-pound increases), cylinders at roughly double R-32's price, A2L equipment carrying 15 to 20 percent higher manufacturing cost, and per-truck retooling at $3,000 to $8,000. Then EPA removed the install deadline effective July 2026, repricing legacy R-410A inventory positions overnight. Date-stamp every refrigerant and equipment price in every bid.

Can R-410A systems still be installed?

Under the federal rule effective July 27, 2026, units manufactured or imported before January 1, 2025 can be installed until supply runs out, and existing systems can be serviced indefinitely (reclaim economics apply as virgin stocks deplete). State law can be stricter; New York kept its own cutoff. Verify the current federal and state posture before quoting; this rule has already changed twice.

Is A2L certification worth the cost?

The 2026 market answered: certified, tooled shops billed 18 to 30 percent labor premiums while the majority caught up, behind a Section 608 update and a few thousand dollars of tools per truck. Compliance capacity is pricing power in every trade; HVAC's version just paid back fastest.

What is included in the monthly fee?

Three tiers, and which one you are in depends on how much of the work you want off your desk. Core is where you stop guessing: job costing built against the way you estimate, a 13 week cash forecast, monthly WIP, and a monthly meeting that ends in decisions, while your bookkeeper keeps doing the books. Executive is where you stop touching the books, because we run the bookkeeping and the controllership as well. Strategic is where every job shows its margin while it is still running, because the job costing and WIP platform is set up and managed for you. No payroll. No scope gaps.

How long does onboarding take?

Sixty days. We migrate your books back to the start of your last taxable year, set up ControlQore, and build your job costing structure from scratch. Fully operational in two months.
