Arizona HVAC marketing with the ROC line on every ad and EER2 on every quote

Arizona wants your license number on nearly everything a heating and cooling company prints, with the letters "ROC" in front of it. A missing line can bring discipline from the registrar, so check every ad and form once.

Arizona's license number rule names the places. The number goes in a conspicuous spot wherever work is being done. It goes on every written bid and estimate. It also goes on published ads, letterheads and the documents you send customers. The Arizona page covers why the number belongs in your profile and footer. This is the detail underneath it.

• Online, radio and billboard ads. These may leave the number off in one case. The ad must carry a web address that links directly to a site that prominently shows your licensed name and number. So the landing page behind each Google or Facebook ad needs both where a visitor sees them. The homepage alone is not enough.
• Business cards and directory ads count. Arizona's definition of an advertisement includes them. A trade association directory sent only to members does not count.
• So does the name. Contracting under any name your license does not carry is grounds for discipline. If the brand on your trucks differs from the licensed company, set the licensed name beside it. Do not let the brand replace it.

Your license class decides what work you can advertise. Arizona's residential class rules and the rules beside them draw the lines:

• R-39, residential. It covers comfort cooling, refrigeration and evaporative cooling. It also covers ventilating and heating, with or without solar equipment. It allows a new circuit on an existing panel or sub-panel, but not a new panel or sub-panel. So a heat pump page that promises a panel upgrade needs a contractor whose license covers that work.
• C-39, commercial. A restaurant's rooftop unit, office ductwork and air balancing sit here, in the commercial class rules.
• CR-39, both. The dual class joins C-39 with the residential R-39R Air Conditioning and Refrigeration class.
• Closed subclasses. Several narrower R-39R classes take no new applicants. One is the class for evaporative coolers and ventilators. A shop still licensed only for one of these should not run ads for refrigerated air installs.

A missing number does not void a contract, but the registrar can discipline you for it. Bigger jobs carry more printing duties. Any contract over $1,000 must print your license number, the deposit and the progress payments, under Arizona's home improvement contract rule. It must also print the owner's right to complain to the Registrar of Contractors, in 10-point bold type. Not legal advice; confirm with counsel.

The monsoon brings a second wave of summer calls, and many come late in the season. Both the storm ad and the replacement contract carry legal risk, so word them with care.

NWS Phoenix counts the season from mid-June through September. Its monsoon safety page warns that a desert thunderstorm rarely gusts below 40 mph. The worst top 100 mph and do damage like a tornado's. Dust storm warnings expect gusts of 40 to 60 mph.

A storm page should name the checks you actually make afterward. Those include the rooftop unit's mounting, a dust-packed condenser coil and a system that will not restart after an outage. That answers what a homeowner is typing that evening.

Keep it running late. The 2025 season saved its storms for the end. The NWS season review puts roughly two thirds of that year's Arizona lightning after the middle of August. A storm campaign paused in July would have missed most of it.

Storm ad wording carries real exposure. Arizona's Consumer Fraud Act makes deception, a false promise or a misrepresentation in an ad unlawful. That holds even when no one was fooled. It bites on an ad that blames the dust storm for a ruined compressor before anyone opened the panel. It also bites on a storm special whose price is not the price.

Deposits matter too. The attorney general's home improvement page caps a sensible down payment at one third of the job. A storm offer under that line reads well to an owner who has seen it.

A booked visit does not switch off the federal cancel rule. Arizona's own cancellation law reaches only sales made without prior invitation, appointment or consent.

The federal rule reaches further. The FTC's Cooling-Off Rule covers sales of $25 or more made at the buyer's home, even when the buyer invited the seller. Its exception covers the repair or maintenance the homeowner asked you out for, and the parts that repair needs. A replacement system sold on that visit falls outside it. So that contract generally carries the federal three-day cancellation notice.

If your team also knocks on doors after a storm, our Arizona pest control page sets out the state's door-to-door rules. Have counsel check the storm contract and its notice together.

Some air conditioners sold legally in most states cannot be installed in Arizona. Your quotes and system pages need the rating that decides it, EER2, the rating at full load on a hot afternoon.

A split central air conditioner under 45,000 Btu/h has to clear an EER2 line here. At 14.3 SEER2, that line is 11.7 EER2. At 15.2 SEER2 or more, it is 9.8 EER2. Below the line, the unit carries a yellow-label notice naming the only places it may be installed, under the federal EnergyGuide label rule. The list holds 46 states, DC and the territories. Arizona is not on it, and neither are California, Nevada or New Mexico.

The HVAC page covers the SEER2 floors. This is the line the Southwest adds. A page or quote that sells on SEER2 alone can offer a unit that cannot legally go in here. Print the EER2 beside the SEER2 on every system page and proposal. Have whoever builds estimates read the label notice before a model goes on one.

Utility wording needs the same care. APS keeps a list of Qualified Technology Installers for cooling and heating. To be listed, a contractor is registered with the Registrar of Contractors and holds a BBB rating of B or better. It is also trained on APS programs and follows APS's logo use guidelines. APS tells customers approached by an installer to check the list.

A shop that is not listed should not write "APS approved" or use the logo. Google's unacceptable business practices policy bars ads that imply backing from an organization that has not given it. Google suspends for that without warning.

What any shop can say accurately is what the program pays the customer. APS's Cool Rewards gives a $50 enrollment credit per smart thermostat. It adds $35 a season, for up to 20 conservation events between June 1 and September 30. A customer who buys the thermostat through APS Marketplace gets that $50 and the first $35 at checkout instead, up to $85 off. So an offer should never add the two together. Name the credits as APS's, never as a discount you pay.

The credits and the installer list are APS's alone. APS serves 11 of Arizona's 15 counties, as its August 2026 newsroom note says. So check whose meter is on the house before an offer goes to a ZIP code. A shop whose customers are on another utility's meters needs that utility's own terms, which this page does not cover. Ask counsel before an ad leans on APS's name.
