Arizona is one of the states where checking a contractor is genuinely easy and almost nobody does it. The Registrar of Contractors publishes a free public license record for every licensed entity in the state — status, classification, qualifying party, former names and complaint history — and reading one takes about ninety seconds. Established in 1931, the agency licenses and regulates over 45,000 residential and commercial contractors and investigates complaints against licensed contractors and unlicensed entities alike.

Phoenix is where that ninety seconds gets skipped. A system quits in the second week of July, the house is past 95 degrees by mid-afternoon, and the first company that can put a truck in the driveway is holding a signed contract by dinner. Heat compresses the decision, and the license number on the truck door goes unread. What follows is how to verify a license, how to read the complaint history sitting behind it, what the state's financial backstop actually pays, and which questions belong in front of a signature rather than after one.

What is the difference between a licensed, bonded, and insured contractor?

The three words travel together in advertising and mean different things in law. Licensing is the first: the license record states a classification, and the ROC tells homeowners to make certain the contractor's license class allows for the work listed in the contract. A classification that does not cover residential air conditioning is not a technicality on a changeout — it is the wrong license for the job in the driveway.

Bonding is the second, and it is automatic rather than reassuring. To obtain a license, a residential contractor must post a cash deposit or surety bond, and the ROC sets that amount between $4,250 and $100,000 according to classification and anticipated annual gross volume. A contractor holding a dual residential and commercial license carries both penal sums. The bond is a limited pool that every claimant against that contractor shares; it is not an insurance policy written for one homeowner's loss.

Insurance is where the phrase breaks. With the exception of workers' compensation, the ROC does not require a licensed entity to carry insurance, and the agency notes that many of the complaints it receives come from owners who believed they had hired a licensed, bonded and insured contractor and had not. The practical step is to ask for a certificate of insurance issued by the carrier rather than a line of text on a proposal.

Generic advice says make sure they are insured. In the Valley the stakes are concrete: a rooftop package unit changeout puts a crane, a crew and a several-hundred-pound cabinet directly over the living room of a 1970s or 1980s Phoenix house, and the curb, the roof penetration and the duct drops are all part of the scope. A $4,250 license bond is not the instrument that pays for a damaged roof deck. General liability coverage is, and it is the one item in the phrase that the state does not check for anybody.

There is a fourth layer specific to residential work. A residential contractor must either pay into the Residential Contractors' Recovery Fund or post a second bond of $200,000. Most participate in the Fund, so asking which of the two applies is a fair question, and the answer determines which remedy a homeowner would actually use later.

How do I check complaints and disciplinary history on the Arizona ROC website?

The portal is at azroc.my.site.com/AZRoc/s/contractor-search. License numbers are six digits, and a leading zero must be included — a license listed as 1234 is searched as 001234. Searching a person requires first name then last name, so 'John Doe' rather than 'Doe, John'. An Advanced Search filters by city, classification and status. One quirk worth knowing: the ROC's own consumer guide warns that advanced search results display in random order and that re-running the same search returns a different order each time. It is a verification tool, not a ranking.

Read the status word before anything else. An ACTIVE license is in good standing and the contractor is able to contract, and the ROC's guidance is to sign only when the status is active at the moment the contract is signed. An INACTIVE license is in good standing but the contractor is not able to contract under it. A license in voluntary cancellation cannot be used to contract unless the entity holds another active license. A SUSPENDED license is not in good standing at all.

Then the history. The record shows whether complaints exist and whether they were resolved, and complaints appear for a period of two years from the date the case closed. That retention window is the single most misread thing on the page: a blank complaint panel proves the last two closed years, not the last ten. A license search also lists qualifying parties, officers, former names and DBAs, which matters when a Valley company rebrands. Under A.R.S. § 32-1162 the named qualifying party is responsible for violations committed while they are on the license, so running the QP's name as a separate search can surface a history the trading name does not.

The confirmation step almost everyone skips is the phone call. The ROC states the only sure way to know a contractor is licensed is to call the agency or check the online license record, and it specifically advises verifying that the person negotiating the project is an authorized representative by calling the number listed on the license record. In August, when a homeowner is dealing with a salesperson in a wrapped truck who may be a subcontracted closer, the difference between the number on the business card and the number on the state record is the whole point of making the call.

What protection does the Arizona Residential Contractors' Recovery Fund give me?

The caps are statutory and precise. An eligible claimant can recover a maximum of $30,000 per residence, an award cannot exceed the amount necessary to complete or repair the project, and the maximum payout against any one residential contractor's license is $200,000, after which no further payments against that license are allowed (A.R.S. §§ 32-1132.01(D) and 32-1139.A). The ROC describes the $200,000 as covering a license up to a maximum of $30,000 per residential property owner on a pro rata basis. Where one contractor has damaged many homes, that per-license ceiling is the number that governs, not the per-residence one.

The statute narrows it further. An award is limited to residential real property, cannot exceed actual damages, and the damages themselves must be established by bids from or work performed by a properly licensed person — the ROC will accept three bids from licensed residential contractors where the work has not yet been redone. Attorney fees and costs are not payable except in contested cases appealed to superior court, and any amount recovered from another source is deducted from the award.

Deposits have their own rule, and it is the one that fits a Phoenix summer. Under A.R.S. § 32-1132.01(C), where a claimant paid a deposit or down payment and no work was performed and no materials were delivered, actual damages are the exact dollar amount of the deposit plus interest at ten percent a year from the date it was paid, subject to the cap. A large July deposit on equipment that never arrives is the scenario that provision was written for.

On mechanics: a claim must be filed within a two-year statute of limitations running from termination of all proceedings, reviews and appeals connected with the Registrar's final order under A.R.S. § 32-1133.01(G), and the documents required include a copy of the property deed and proof of the cost to repair or complete. If an award is made, the Fund does not select or hire the replacement contractor — the check is issued to the homeowner, who contracts with and pays the contractor directly.

One thing is genuinely unsettled in public sources and is not smoothed over here: how a homeowner reaches the Fund is described differently by different parties, and the eligibility rules about which properties and which owners qualify are applied case by case. The ROC's Recovery Fund department is the authority on both points and takes calls directly. A claim against the contractor's license bond is a separate remedy with its own process, and pursuing one does not automatically pursue the other.

What questions should I ask a contractor before signing anything?

Start with the paperwork the state itself names. The ROC recommends requesting written estimates from at least three contractors, requesting and checking a list of references, and obtaining a written contract that includes all services to be performed, the contractor's license number, and start and completion dates. A quote that names a brand and a tonnage is a price, not a scope. On a Valley changeout the scope is what states whether the line set is replaced or flushed, whether the plenum and transitions are rebuilt, whether the disconnect and whip are new, and whether an existing roof curb is reused or replaced.

Then sizing, which in Phoenix is not a formality. A load calculation run against a design day near 115 degrees is the difference between equipment that holds setpoint in July and equipment that runs continuously and still loses ground. SRP requires Manual J load calculations to be submitted with the rebate application on single-stage systems, and states that applications without them are delayed or denied; load calculations are not required for multi-stage or variable-capacity systems. Under SRP's contractor terms the installer certifies that installed capacity is within 15% or a half-ton of the load estimate, that airflow is within plus or minus 10% of the blower's rated capacity, and that refrigerant charge is within plus or minus 5% of manufacturer specification. Those three certifications convert neatly into three questions.

Interrogate any rebate or credit printed on the quote. SRP's terms require the customer to be a permanent SRP residential electric customer, the system to be installed by a contractor licensed in Arizona to install residential air conditioning before April 30, 2027, and the work to replace or supplement an existing central AC or heat pump; new construction, window units and installations in garages or other non-habitable space do not qualify, and SRP may inspect the installation. Rebate amounts and effective dates are set by SRP and change between program cycles, so the figure should be confirmed on SRP's own rebate page rather than taken from a proposal. Check the utility bill for which utility serves the meter before assuming any program applies, and confirm the status of federal credits on the IRS page for the year the system is placed in service.

Close with permits and exits. Ask who pulls the permit and under which municipality — thresholds and fees are set by each city's building department, so the reader's own city is the place to confirm them, and the permit number belongs in the file. Ask what happens if the load calculation returns a different tonnage than the quote assumed. Ask which portion of the warranty is the manufacturer's and which is the company's labor coverage. Then verify the license number that appears on the contract before signing it, and keep the contract and payment records: the ROC notes that detailed records speed the processing of a claim if one is ever needed.
