The R-410A deadline you were told about is gone

Four days ago a federal rule took effect that quietly undid the deadline every HVAC contractor and supply house in this region has been planning around for eighteen months. If you were told you had to install by January 1, that is no longer true. We read the rule, and the details are below.

Also in this issue: the ten-minute maintenance job that prevents the most avoidable water-damage claim of an Arkansas August, free legal help for anyone running their own shop, a Fayetteville vote Tuesday that would cut the minimum residential lot width by a third, and six local training deadlines in the next four weeks.

One more hot one today, with a heat index near 104, then relief. Storms are likely late tonight, a 50 percent chance before 1 a.m., and a front clears the heat out behind them. Saturday is mostly sunny and 83 with a northwest wind gusting to 25 mph, and Sunday is 85 and calmer. If you have exterior work waiting, this weekend is the best window we have seen in a while.

Who this is for: HVAC contractors, supply houses, and any homeowner who has been told they need to replace a working system.

EPA published a reconsideration rule in the Federal Register on May 26, 2026. It took effect July 27, 2026. In EPA's own words, it "removes the installation deadline for systems in the residential and light commercial air conditioning and heat pumps subsector, where all specified components of such systems were domestically manufactured or imported before January 1, 2025."

EPA's fact sheet is blunter: the rule "removes the January 1, 2026, installation compliance date" and "allows pre-2025 inventory of air conditioning systems to be installed until supply runs out."

What did not change. The 700 GWP limit on manufacturing and importing new residential and light commercial AC and heat pump equipment is still in force, with its January 1, 2025 compliance date. Sale and distribution compliance runs to January 1, 2028. In practice, new equipment is still R-454B or R-32. What changed is that R-410A equipment already sitting in the country can now be installed with no cutoff.

For homeowners, quoting EPA directly: "There are no requirements to stop using any specific equipment or appliance currently in use. Consumers will be able to continue using their equipment until the end of its useful life." And on repairs: "You can continue to repair your existing refrigeration, air conditioning, and heat pump system. This includes replacing a major component like a condensing unit or compressor."

EPA does add that availability of HFCs and components may lessen over time as the phasedown proceeds. That is a supply question, not a legal one.

One thing worth knowing: parts of this same EPA rule are being challenged in court. AHRI, HARDI, PHCC and ACCA filed petitions in late June. Those challenges target the commercial refrigeration provisions, not the residential relief described here. ACCA in fact said it "appreciates EPA eliminating the install deadline for R-410A split-system equipment." Nothing above is stayed.

Why we are leading with this. A lot of people in this region were told, in good faith, that a hard installation deadline was coming. Some were told it by someone selling a system. As of Monday that deadline does not exist. We are not going to tell you whether R-410A or R-454B is the better buy, because that depends on your equipment, your installer and what is actually on the shelf. We are telling you the rule changed so you can ask a better question.

Here is the thing most people get wrong: an air conditioner that quits on the hottest afternoon of the year often has not broken. It has protected your house from a water leak.

What is actually happening. Your AC cools by running warm indoor air across a cold evaporator coil. Water condenses out of that air, drips into a pan, and leaves through a drain line. In an Arkansas August a working system pulls gallons of water a day out of your house. That pan and pipe are warm, dark and permanently wet, which makes them an excellent place for slime and dust to build into a plug.

When the line plugs, the pan fills, and one of two things happens. Either it overflows, which is how you get a stain on the ceiling under an attic air handler. Or a float switch catches it first and shuts the system down. Trane describes it plainly: "If the switch detects a potential condensate overflow issue, it will shut the outdoor compressor and condenser fan down." Trane also lists the usual causes, which include dirt, debris, mold growth "or even spider webs."

There is a comfort angle too. The Department of Energy notes that a clogged drain stops the unit from pulling humidity out, which is why a 78-degree house can feel like 85.

What you can safely do yourself. DOE puts this squarely in the homeowner column: "check your unit's drain to make sure it isn't clogged."

While you are standing there, change the filter. DOE says routinely replacing or cleaning filters "can lower your air conditioner's energy consumption by 5-15 percent."

Where this stops being a homeowner job. Call a licensed tech if the float switch has already tripped and the system will not restart after you clear the line, if there is already water staining a ceiling or wall, if the line will not clear or re-clogs within days, if the coil is iced up, or if anyone mentions refrigerant. Refrigerant work is federally regulated and requires EPA Section 608 certification. It is never a DIY job.

A line that re-clogs fast usually means something structural: bad slope, undersized pipe, a missing trap, or a rusted pan. Carrier's own guidance is that clearing a stubborn line "is best handled by a qualified pro with the right tools to unclog an AC drain line without damaging the PVC piping."

One honest nuance. ENERGY STAR's checklist puts "inspect the condensate drain" in the contractor column of an annual check-up, while DOE's homeowner guide puts drain maintenance in the homeowner column. Both are right, and the split is the point: routine prevention and a wet-vac pull is yours. Diagnosing why it backed up is the tech's.

Skip the bleach. Carrier notes that vinegar and bleach may not fully prevent blockages, because many clogs are debris rather than organic buildup. Vinegar is the safer thing to put in your own line. The vacuum is what actually moves a plug.

Safety, once: there is a blower motor and line-voltage wiring inside the air handler. Cut power before your hands or tools go near it.

One more thing this month. If your air handler is in the attic, which it is in most NWA houses with an upstairs, walk the ceilings underneath it and look for a stain or a soft spot. August is peak condensate season. It is the month a slow pan leak announces itself, and the month you can still catch it cheap.

Three housing and development items were tabled 8-0 on July 21, specifically until Tuesday, August 4, at Fayetteville City Hall, 113 W. Mountain St. All three cleared the Planning Commission:

For builders and remodelers this changes what fits on an infill lot. For homeowners it changes what can go up next door. Public comment is taken at the meeting. Check the city's agenda for the start time.

ARDOT is taking input on improvements to about a mile of U.S. 412 at the I-49 interchange in Springdale, Job 040894, construction estimated at $10 to $15 million. The open house was Thursday evening in Springdale.

Online comments are open until 4:30 p.m. Friday, August 14, with materials at ardot.gov/events/pi-040894/. If your crews run 412 daily, this is the cheapest hour of influence available to you all year.

Every price below is what the school publishes on its own site, checked July 30, 2026.

Three notes. NWTI's $750 Basic Welding is the cheapest way into the trade we have found anywhere in the region, one semester of Monday nights, no application deadline, apply until it fills. The ABC apprenticeship requires you to already be employed by an electrical or plumbing contractor, so the real first step is landing the job. And the safety conference date is confirmed on the Arkansas Department of Labor and Licensing's page, but venue, cost and registration are still TBD. Nita Matlock at 501-682-9092 is the contact.

A note on how we checked these: NWTI's website only shows its prices and dates after the page runs its scripts, which means search engines and automated tools read those pages as blank. We opened them by hand. If you have ever searched for NWTI tuition and come up empty, that is why.

Almost nobody we talk to knows this exists.

The Arkansas Office of Skills Development runs four employer training grant programs. Three of them, Skills Gap, Grow Our Own and Customized Technical, reimburse up to 75 percent of the total project budget. Professional Development reimburses up to 50 percent.

Call 501-683-1152 before you count on any of it.

Our own caveat. OSD's published rules document is dated February 2016. It is the current document linked from their own grants page, but it is a decade old, and every award we could find in the news went to manufacturing, healthcare or tech rather than a residential contractor. The rules are industry-neutral on their face. We are not going to tell you a residential trades contractor qualifies until someone at OSD says so out loud. Ask them, and tell us what they say.
