Stay ahead of EPA mandates, technology shifts, and best practices for the HVACR trade.
The AIM Act phasedown is tightening supply. Prices at the counter are rising. And the contractors who track refrigerant cost per-system are winning the replacement conversation — while everyone else is still quoting by the pound.
Spring startup season is here — and the first real-world seasonal variance decisions under Subpart C are happening this week. Here are five scenarios playing out in the field right now, and exactly how to handle each one.
You're compliant with Subpart C. Good. But if you operate in California, Washington, New York, or nine other states, there's a second set of rules on top of the federal ones — and some of them are stricter. Here's what small contractors need to know.
Sixty-eight days in. Your techs have been calculating leak rates, documenting service calls, and navigating new rules on the fly. But has anything slipped through the cracks? Here's a systematic self-audit to catch the gaps before someone else does.
Since January 1st, reclaimed refrigerant can't contain more than 15% virgin HFC by weight. That sounds like a rule for reclaimers — until you realize you're the one installing it, and the paperwork follows the cylinder to your truck.
Subpart C lets you skip the leak rate calculation when adding refrigerant back after a seasonal removal. But four conditions must be met — and most contractors are getting at least one of them wrong.
Nine weeks of Subpart C coverage, distilled into one reference guide. Print it. Laminate it. Put it in every truck. This is everything your techs need to know — on every service call, for every covered system.
Subpart C exempts residential and light commercial AC and heat pump systems. But the line between 'light commercial' (exempt) and 'commercial comfort cooling' (covered) isn't where most contractors think it is.
There's a second threshold most contractors aren't tracking. If total refrigerant added to a system exceeds 125% of its full charge in a calendar year, you must file a report directly with the EPA by March 1st. Here's how that math works — and how fast it adds up.
The regulation creates the demand. Your service agreement fulfills it. Here's how to have the building owner conversation, restructure your maintenance contracts, and make Subpart C the best thing that ever happened to your recurring revenue.
Your tech calculated a leak rate above the threshold. The 30-day clock is running. Here's the step-by-step workflow — from detection through repair, verification testing, and what happens if the fix doesn't hold.
Two weeks into Subpart C, the same five documentation gaps keep showing up. None of them are hard to fix — but all of them are audit liabilities. Here's the checklist.
Right before New Year's, the EPA eased enforcement on one refrigerant rule. Contractors are assuming that means the other one got relaxed too. It didn't. Here's why the difference matters.
In 3 days, every time your tech adds refrigerant to a 15-lb+ system, a leak rate calculation is required by law. Here's exactly how to do it — with real numbers from real equipment.
The EPA just dropped the refrigerant reporting threshold from 50 to 15 pounds. That means your customer's 5-ton rooftop unit is now federally regulated — and you've got 10 days to figure it out.
