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 costs 15 to 20 percent more to make (leak sensors, revised charge limits) and 8 to 10 percent more at the customer. Then EPA reversed course. It declared the install deadline a low enforcement priority in December 2025. A final rule effective July 27, 2026 removed it, so pre-2025 R-410A units can now be installed until the existing supply is used up (New York's state cutoff excepted). Contractors who priced, stocked, tooled and certified for one set of rules saw those rules change twice in eighteen months.

THE COST, SOURCED.

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 have about 8% net profit at $1M to $5M, rising to roughly 10% at $5M to $10M. The CFOS net profit target is 11.5% before taxes at $1M to $5M, the trade's average plus 3.5 points, never below 10%. You find a problem like this in the distance between those two figures. One bad job won't tell you.

Gross margin over the same bands is 24% to 25%,against CFOS targets of 26.5% and 27.5%.

COMMON QUESTIONS

FREQUENTLY ASKED.

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

Under the federal rule effective July 27, 2026, units manufactured or imported before January 1, 2025 can be installed until supply is used up. Existing systems can be serviced indefinitely (reclaim economics apply as virgin stocks deplete). State law can be stricter, and New York kept its own cutoff. Check the current federal and state rules before you quote. This rule has already changed twice.

The 2026 market answered. Certified, tooled shops billed 18 to 30 percent labor premiums while most others caught up. It took a Section 608 update and a few thousand dollars of tools per truck. In every trade, being able to do the compliant work lets you charge more. In HVAC it paid back fastest.

Three tiers, and which one you are in depends on how much of the work you want off your desk. On Core we build your plan every month and your team does the work: 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. On Strategic we build the plan, track it and adjust it every month: our team does the bookkeeping and the bank reconciliations, and the job costing and WIP software is set up and managed for you, on your own online software or ours. On Platinum we manage the money side for you every week: our team handles your bills and receivables the way an in-house controller would, and you approve every payment. We don't do payroll.

Sixty days. We migrate your books back to the start of your last taxable year and build your job costing structure from scratch, and on Strategic and Platinum we set up the job costing and WIP software too. You're fully up and working in two months. The onboarding fee is one time, the same for every tier, and set by your revenue band.
