A homeowner in Chandler got two quotes for a four ton replacement last week. Yours was $14,800. The other was $11,600. Same tonnage, same nominal efficiency, same ten year parts warranty on the sheet. You lost the job and never found out why, because the homeowner could not explain it either. The difference was the refrigerant, and neither quote said so.
This is not a pricing failure on your side. On May 21, 2026 the ACHR News reported that the EPA had finalised a revision to its 2023 Technology Transitions rule removing the January 1, 2026 installation deadline for residential and light commercial air conditioning above 700 GWP, for equipment manufactured or imported before January 1, 2025. Distributors may now run that inventory down instead of stranding it. So two contractors in the same Arizona zip code can quote the same house from two different refrigerant generations, legally, on the same afternoon.
This is fixable, and the fix is written words rather than a better rebuttal at the kitchen table. What follows is what the EPA changed and what it did not, six ways a two refrigerant market damages an HVAC pipeline and margin, how the picture differs in Arizona, Indiana, Colorado and Florida, and what you publish so the comparison is settled before the second quote arrives.
What the EPA Changed in 2026, and What It Did Not
The EPA removed an installation deadline, not the phasedown behind it. The 2023 Technology Transitions rule had barred installing new residential and light commercial air conditioning using refrigerant above 700 GWP from January 1, 2026. The 2026 revision lifts that deadline for units manufactured or imported before January 1, 2025, so existing stock can be installed until it runs out. The AIM Act production and consumption phasedown that makes R-410A steadily scarcer was untouched.
The Rule Revision and Who Welcomed It
EPA Administrator Lee Zeldin framed the revision as choice, saying the action allows businesses to choose the systems that work best for them and saves them billions of dollars. AHRI President and CEO Stephen Yurek disagreed publicly, arguing the rule works against basic supply and demand and that extending the compliance deadline maintains and even increases demand. Both readings are correct from where they stand, and the contractor is caught between them, holding a quote that is now competing against older stock.
The 2029 Step Nobody Is Quoting
The AIM Act phasedown continues regardless of what may be installed. EPA's own phasedown fact sheet sets HFC production and consumption at 90% of the historic baseline in 2023, dropping to 60% in 2024 and to 30% of baseline in 2029. A system charged with R-410A and installed in Mesa in late 2026 will be a normal service call in 2028 and an expensive one from 2029, because the refrigerant it needs will be produced under an allowance pool half the size of today's. That is a homeowner cost, three years out, that appears on nobody's estimate.
The Rules Stopped Being National on September 25, 2026
State refrigerant rules do not automatically follow the federal change, and one state said so out loud this month. The ACHR News reported on September 25, 2026 that Washington's Department of Ecology will not revise WAC 173-443 to match the EPA, keeping its requirement that new residential and nonresidential air conditioning use refrigerant below 750 GWP from January 1, 2026. Leonard Machut, fluorinated gas section manager at the department, put it plainly: Washington law, in this case, will supersede the recent federal actions. AHRI's state tracker lists 16 states with their own HFC rulemakings.
Arizona Is on the Federal Side of That Line
Arizona has no state HFC rule, so the federal extension applies in full and Arizona is one of the markets where the two refrigerant quote is now normal. Arizona does not appear on AHRI's list of states with HFC rulemakings, and neither do Indiana or Florida. Colorado does appear, but its Regulation 22 reaches aerosol propellants, chillers, foam and stationary refrigeration rather than residential air conditioning. For a contractor in Phoenix, Tucson or Mesa the practical effect is that nothing stops the company down the road quoting pre-2025 stock at a price you cannot match, and nothing requires them to explain it.
Six Ways a Two Refrigerant Market Hurts Your Pipeline and Margin
A market where two generations of equipment are both legal to install does not just split inventory. It breaks the comparison the homeowner is making, and six parts of your business pay for it.
1. You Are Bidding Against Equipment That Is Already End of Line
Your A2L quote is competing with stock a distributor needs to clear, which means the other price is not a better business, it is a liquidation. That is a difficult thing to say to a homeowner without sounding bitter, and most estimators either say it badly or say nothing. Companies that standardised on R-454B or R-32 through 2025 are now the expensive option in every side by side, through no decision of their own.
2. In Phoenix the Refrigerant Choice Is a Service Cost Decision, Not a Philosophical One
Arizona runtime turns a refrigerant charge into a recurring exposure rather than a one off. Phoenix recorded 39 days at 110 degrees or hotter in summer 2026, its second hottest on record, and 29 nights that never dropped below 90, on National Weather Service data reported by Axios Phoenix on September 15, 2026. A condenser working those hours will see a service call in its life, and the question is what the refrigerant costs when it does. In a heating dominant market that argument is theoretical. In Mesa and Glendale it is arithmetic.
3. Your Good Faith Quote Reads as Overpriced Because No Page Explains It
The higher quote loses when the only difference the homeowner can see is the number. Almost no HVAC website in Arizona has a page explaining what changed in 2026, what a pre-2025 unit is, what the 2029 allowance step means for a service call, or why two quotes can differ by thousands. Without that page, the estimator has to teach the whole subject standing in a garage, in the ten minutes before the homeowner gets bored.
4. Distributor Inventory, Not Your Strategy, Is Setting Your Price
Which refrigerant you can quote this week depends on what your branch has on the floor, and that varies branch to branch and month to month. A company running three trucks out of two supply houses can find itself quoting A2L on Monday and R-410A on Thursday with no change in policy. That is not a purchasing problem you can fix with a phone call, it is a reason your average ticket moves for reasons your CRM cannot see.
Pull your last 40 lost replacement quotes and add one column: which refrigerant you quoted. Then call ten of them and ask what the winning quote was and what refrigerant it used. Most HVAC companies have never asked, and the ones that do usually find the losses cluster hard on one side. That column tells you whether you have a price problem or an explanation problem, and they need opposite fixes.
5. The Homeowner Is Researching Refrigerant Before They Call You
Refrigerant has become a consumer search topic, which it never was before 2025. Homeowners are typing the refrigerant name off the old data plate, asking whether R-410A is being banned, asking whether they should buy now or wait, and asking an AI assistant to compare the two. Those searches happen before any estimator is in the driveway, and whoever answered them in writing has already framed the decision by the time the phone rings.
6. Your Warranty and Service Promise Now Needs a Different Sentence
Selling a ten year parts warranty on a system whose refrigerant gets scarcer every year invites a question you should answer first. A homeowner who understands the phasedown will ask what happens if the system leaks in 2030, and the honest answers differ by equipment. Companies that put that answer in writing convert better than companies that improvise it, because the improvised version always sounds like a hedge.
Where the Split Bites Hardest: Arizona, Indiana, Colorado and Florida
The same federal rule produces four different sales problems in Arizona, Indiana, Colorado and Florida, because runtime decides how much the refrigerant matters and licensing decides how easy it is for a low bid to enter the market.
Arizona: Maximum Runtime, Federal Rules, Checkable Credentials
Arizona is the market where the refrigerant decision costs the most over the life of the system, because the equipment works harder than almost anywhere else in the country. Phoenix averaged 97 degrees across June, July and August 2026, its second hottest summer on record behind 2024, with 39 days at or above 110 and 29 nights that stayed above 90, on National Weather Service figures reported September 15, 2026. A system in Scottsdale or Tucson does not get a shoulder season to recover in, so leak rates, compressor hours and the cost of a recharge all land harder than they do in a mixed climate.
Arizona also gives you something Ohio contractors would envy, which is a credential the homeowner can verify in thirty seconds. The Arizona Registrar of Contractors issues R-39 for residential air conditioning, C-39 for commercial and CR-39 for both, a licence is required for work above $1,000, applicants need four years under a licensed contractor with technical training substituting for two, and residential licensees sit behind a $200,000 recovery fund in addition to their own bond. Put your ROC number, classification and recovery fund status on the quote and on the site. The low bid clearing old stock rarely bothers.
The Arizona search opening is the comparison itself. The homeowner who just received two quotes is searching the refrigerant names, the phase down, and whether they should take the cheaper unit, and the companies competing for Arizona HVAC leads are still publishing tune up coupons and financing banners. A page that lays out both options honestly, names the 2029 allowance step, and gives a number for what a recharge costs in each case will be read, quoted by AI assistants, and remembered when the second estimator leaves.
| State | How much the refrigerant choice costs over the system's life | State rules and licensing that shape the market | The argument that wins there |
|---|---|---|---|
| Arizona | Highest of the four: 39 days at 110 or hotter in Phoenix in 2026 and no shoulder season | No state HFC rule; ROC issues R-39, C-39 and CR-39, licence required above $1,000 | Lifetime service cost, backed by your ROC number and the recovery fund |
| Indiana | Lowest of the four: heating dominant, so cooling runtime is a fraction of Arizona's | No state HFC rule and no state HVAC licence; Indianapolis and Marion County license separately | Match the furnace and coil properly and sell the system, not the refrigerant |
| Colorado | Moderate: wide shoulder seasons and altitude derating cut cooling hours | Has Regulation 22, but it covers aerosols, chillers, foam and refrigeration, not residential AC | Correct the assumption that Colorado's HFC rule bans R-410A, then sell on sizing |
| Florida | High: year round cooling plus salt air corrosion shortens the interval to the first leak | No state HFC rule; DBPR Class A is unlimited, Class B caps at 25 tons and 500,000 BTU | Leak rate and coil life, with certified statewide licensure as the trust signal |
Indiana, Colorado and Florida: Three Different Versions of the Same Quote
Indiana is where the refrigerant argument matters least and the matching argument matters most. Indiana is heating dominant, so an Indianapolis or Fort Wayne condenser runs a fraction of the hours a Phoenix one does and the lifetime refrigerant exposure is genuinely smaller, which means an estimator who leads with the phasedown in Evansville sounds like they are selling fear. The real Indiana risk is a cheap condenser paired badly with an existing furnace and coil. Indiana has no state HVAC licence, so credentials are local: the Board of Heating and Cooling Examiners of Indianapolis licenses for the city and Marion County across five classifications, requires five years of documented HVACR experience verified by employers on letterhead, three professional references, an EPA certification card, a $5,000 surety bond and a $189 licence fee. Publish that licence number, because in Indiana it is the only one there is.
Colorado's problem is the opposite of Arizona's: the homeowner thinks there is a rule when there is not. Colorado does appear on AHRI's list of states with HFC rulemakings, and Denver homeowners who have read about Regulation 22 sometimes arrive believing R-410A is already banned in the state. It is not. Regulation 22, adopted by the Colorado Department of Public Health and Environment in May 2020, covers aerosol propellants, chillers, foam and stationary refrigeration rather than residential air conditioning, so a Denver or Colorado Springs homeowner may legally be sold either generation. Colorado has no state HVAC licence either, so Denver runs its own: four classifications, four to eight years of field experience, EPA Section 608, ICC exams and fees of $40 to $60. The Colorado page that corrects the Regulation 22 assumption in plain words will get read by every homeowner in the metro who half remembers a headline.
Florida is the state where the first leak arrives soonest, which changes which argument lands. Year round cooling plus salt air corrosion on coils and line sets in Miami, Tampa and Fort Myers shortens the interval between installation and the first refrigerant service, so the 2029 allowance step is not an abstraction for a Florida homeowner buying today, it is roughly the second or third service visit. Florida also has real statewide licensure to point at: the Department of Business and Professional Regulation issues Class A air conditioning contractor licences with unlimited scope and Class B licences limited to 25 tons of cooling and 500,000 BTU of heating in any one system, requires four years of experience with one year supervisory, two exams at 70% or better, and minimum general liability of $100,000 with $25,000 property damage. A certified licence works statewide while a registered one works only where the competency exam was passed, which is a distinction worth spelling out in Jacksonville and Orlando where out of area crews appear after every storm season.
Rebuilding the Quote So the Comparison Happens on Your Terms
The estimate is the document where the two refrigerant problem gets solved or lost, and most HVAC estimates have not changed since 2023. Three additions do most of the work.
Name the Refrigerant on Every Line, Including the Competitor's
Put the refrigerant on the quote in the same size type as the tonnage, and add one line stating what the alternative would be and what it would save today. A quote that names both options reads as advice rather than a sales document, and it removes the homeowner's suspicion that you are hiding the cheaper path. It also means the second estimator walks into a conversation you have already framed.
Price the Ten Year Cost, Not the Install
Show the install price and an estimated ten year cost that includes one refrigerant service event, using a real number from your own service history for each refrigerant. This is the single most persuasive thing you can put in front of someone choosing between $11,600 and $14,800, because it converts an abstract regulation into a figure they can compare. Use a range and say it is an estimate. Never invent precision you do not have.
Answer the Resale and Warranty Question Before It Is Asked
Write down what happens if the system leaks in 2030 for each option, and what a home inspector or buyer's agent is likely to say about each at resale. Most homeowners have not thought about resale and every one of them cares once it is raised. Getting there first is worth more than another 2% off the price.
Build one page and one page only before you touch anything else: what changed in 2026, what a pre-2025 unit is, why two quotes differ, what the 2029 step means, and what a recharge costs on each refrigerant in your market. Link it from every estimate you send. Contractors who publish this page stop losing the comparison in silence, because the homeowner now has your explanation on their phone while the other estimator is talking.
What Actually Wins the Side by Side
Winning a two refrigerant comparison is a content and timing problem rather than a discounting problem, and three things decide it.
Rank for the Refrigerant Question, Not the Service Keyword
The searches that decide this sale use refrigerant names and regulation words, and almost every HVAC site is optimised for service keywords instead. Homeowners are searching whether R-410A is banned, what R-454B is, whether they should replace before or after the phasedown, and what a pre-2025 unit means. Pages that answer each one in plain language get retrieved by search engines and lifted by AI assistants, and they arrive with a homeowner who already trusts the source.
Get the Explanation Into the Booking Call
The comparison is usually lost before the estimator arrives, so the explanation has to start earlier. A booking call that asks which other companies are quoting and sends the explainer page by text within a minute changes the order in which the homeowner learns things. That is a scheduling script and an automation, not a sales technique, and it is cheaper than the discount it replaces.
Follow Up on the Regulation, Not on the Price
A homeowner who chose the cheaper quote is not a lost customer, they are a service customer with a known future problem. A follow up sequence that checks in at the first service interval, with the refrigerant cost in it, converts some of them into replacements later and most of them into maintenance agreements now. Companies that only follow up with discount offers train people to wait for the discount.
How Leadnox Builds HVAC Demand Around the Refrigerant Question
Leadnox builds HVAC contractors the demand system that settles the refrigerant comparison in writing before the second quote arrives, which is a different brief from generating more replacement leads.
Search and AI Answers Built on the Regulation
Leadnox writes and ranks the pages a homeowner reads between the first quote and the second: what changed in 2026, what a pre-2025 unit is, what the 2029 allowance step costs, and how to compare two quotes that differ by thousands. Localised properly, that means an Arizona page that uses Phoenix runtime and the Registrar of Contractors rather than a national explainer with the state name dropped in, and a Colorado page that corrects the Regulation 22 assumption directly.
Paid Demand Measured on Installed Systems
Leadnox runs performance marketing against installed systems rather than booked estimates, and separates the budget that chases replacement intent from the budget that chases service calls. Install outcomes feed back into the campaigns so spend moves toward the segments that finish, which in a two refrigerant market usually means the neighbourhoods and housing ages where the ten year cost argument wins rather than the ones where the lowest price always does.
Automation That Gets Your Explanation There First
Leadnox builds the booking scripts, text sequences and answering systems that put the explainer page in the homeowner's hands within a minute of the call. That means asking who else is quoting, sending the comparison automatically, following up at the first service interval rather than with a discount, and making sure the callback after the second estimate leaves reaches a person. Being first with the explanation is worth more than being lowest with the price.
The Numbers That Show You Are Winning the Comparison
Four metrics tell you whether the explanation is working or whether you are still losing quietly on price. Review them monthly with sales and service in the same room.
Close Rate on Quotes Where a Competitor Was Also Quoting
Close rate on competitive quotes is the only number that measures this problem directly, and most HVAC companies do not separate it from their blended close rate. Ask on every estimate whether anyone else is quoting and record the answer. If your competitive close rate is more than 15 points below your uncontested rate, the explanation is missing rather than the price being wrong.
Average Ticket, Split by Refrigerant Quoted
Average ticket split by refrigerant shows whether your pricing is drifting with distributor inventory rather than with your own strategy. Track what you quoted, not just what you sold. A company whose A2L average and R-410A average are converging is discounting the newer equipment to compete, which is the most expensive way to solve this.
Traffic and Assisted Conversions on the Refrigerant Page
The explainer page earns its place through assisted conversions rather than direct ones, because homeowners read it and then call. Watch sessions, time on page, and how often it appears in the path of a booked estimate. A page that gets traffic but assists nothing is written for search engines rather than for the person holding two quotes.
Service Revenue From Systems You Did Not Install
Service revenue from other companies' installs is the leading indicator of the replacement pipeline three years out. Every R-410A system going in around you now is a future service customer, and the companies capturing those calls in 2027 will be the ones quoting the replacements in 2030. If that number is flat while installs in your market are rising, your follow up is not reaching the homeowners who chose the cheaper quote.
Frequently Asked Questions
Usually because they use different refrigerants. The EPA's 2026 revision to its Technology Transitions rule removed the January 1, 2026 installation deadline for equipment above 700 GWP manufactured or imported before January 1, 2025, so pre-2025 R-410A stock can still be installed. Arizona has no state HFC rule, so both generations are legal to quote there.
Not for installation of pre-2025 equipment under federal rules. Manufacture and import of the equipment stopped, and the EPA has since allowed remaining pre-2025 inventory to be installed until it runs out. The AIM Act phasedown of the refrigerant itself continues regardless, dropping production and consumption to 30% of the historic baseline in 2029, down from 60% in 2024.
In some states, yes. The ACHR News reported on September 25, 2026 that Washington's Department of Ecology will not revise WAC 173-443 to match the federal change, keeping its requirement that new air conditioning use refrigerant below 750 GWP. AHRI lists 16 states with their own HFC rulemakings. Arizona, Indiana and Florida are not among them.
It depends on runtime and how long they plan to stay. In a high cooling load market the system is more likely to need refrigerant during its life, and that refrigerant gets scarcer after the 2029 allowance step. In a heating dominant market with a short ownership horizon the cheaper install can be the rational choice. Compare estimated ten year cost, not install price.
Name both options on your own quote, including what the cheaper one would save today. Add an estimated ten year cost for each using your own service history, and state what happens if either system leaks after 2029. Presenting both paths reads as advice rather than a sales pitch, and it removes the suspicion that you are hiding the cheaper option.
Win the Quote Comparison Before the Homeowner Makes It
Leadnox builds HVAC contractors the search, paid and follow up systems that answer the refrigerant question for Arizona, Florida and Colorado homeowners before a cheaper quote does, and prices demand on installed systems.
