3.2 Coverages, Limits & Policy Language
Key Takeaways
- Contractor general liability is typically written on an occurrence form; professional liability is often claims-made and may need an extended reporting period (tail) if cancelled.
- CILB's $100,000 / $25,000 figures are aggregate license minimums; a per-occurrence limit and a general aggregate are different caps, and a commercial contract may demand far more than the Board floor.
- A certificate holder is not an additional insured: CILB as certificate holder is entitled to cancellation notice, not policy rights.
- Standard GL pollution and professional-services exclusions can leave a refrigerant leak or a Class A design error uncovered unless an endorsement or separate policy applies.
- Completed operations, not the premises-and-operations grant, is the coverage that responds after a rooftop changeout has been finished and accepted.
3.2 Coverages, Limits & Policy Language
Obtaining a policy that meets Rule 61G4-15.003 is only half of Business & Finance Area B item 8 (Maintain Insurance). The other half is knowing what the policy will actually pay. Two HVAC firms can both show $100,000 public liability on a certificate and have completely different protection after a refrigerant leak, a ladder injury, or a rooftop changeout. The difference is form, limit structure, endorsements, and exclusions.
Why policy language beats the declarations page
The declarations list named insured, policy period, limits, and deductibles. The insuring agreement, conditions, and exclusions decide whether a claim is in or out. CILB audits the certificate. A plaintiff's lawyer, a GC's risk manager, and your own claims adjuster audit the form. For the exam, treat every coverage type as a pair: what it is designed to do and where it stops.
Occurrence versus claims-made
| Feature | Occurrence form | Claims-made form |
|---|---|---|
| Trigger | Injury or damage happens during the policy period | Claim is first made (and usually reported) during the policy period |
| Typical HVAC use | Commercial general liability, commercial auto | Professional liability / errors and omissions; some pollution policies |
| After you cancel | Still covers injury that occurred while the policy was in force, even if the lawsuit arrives years later | Coverage generally ends unless you buy an extended reporting period (tail) |
| Retroactive date | Not the usual GL issue | Claims-made forms often bar injury that occurred before the retro date |
A standard contractor GL policy is occurrence. If a liquid-line joint you brazed in 2024 fails in 2026 and stains a condominium ceiling, the 2024 occurrence policy is the one that responds — even if you have since changed carriers — provided the 2024 policy included products-completed operations.
Claims-made is the usual home of professional liability. Class A contractors may design systems when not prohibited. A load-calculation or equipment-selection error is often a professional service, which GL commonly excludes. If you buy claims-made professional coverage and then drop it, you generally need a tail or the next carrier must honor a retro date. Do not assume CILB's public-liability minimum buys professional coverage; it does not.
Per-occurrence versus aggregate — and CILB's table
A per-occurrence (or per-claim) limit is the most the insurer will pay for one event. An aggregate is the most it will pay for all covered claims in the policy period (sometimes with a separate products-completed operations aggregate).
Rule 61G4-15.003(2)(h) labels the Board amounts as the proper aggregate amount of public liability and property damage. For HVAC that is $100,000 liability and $25,000 property damage. Two exam traps follow:
- Do not substitute the general-contractor $300,000 / $50,000 aggregates.
- Do not assume a commercial subcontract that says $1 million each occurrence / $2 million aggregate is satisfied by CILB's license floor. The Board number keeps the license active; the contract number keeps you on the job.
If three unrelated water-damage claims in one year each exhaust a small property-damage limit, the aggregate can be gone before hurricane season. That is why contractors buy limits above the Board minimum and sometimes an umbrella that sits over GL and auto. An umbrella is excess: it generally pays only after primary limits are used, and it follows the primary form's exclusions unless the umbrella is broader by endorsement.
Additional insured versus certificate holder
These two certificate boxes are not interchangeable.
- Certificate holder is a notice party. Rule 61G4-15.003(2)(i) requires the holder to be the State of Florida, Department of Business and Professional Regulation, the Construction Industry Licensing Board. Being holder does not make CILB an insured and does not give CILB a right to defense or indemnity. It is how the Board learns of cancellation.
- Additional insured is created by endorsement (often CG 20 10 for ongoing operations and CG 20 37 for completed operations, or a blanket additional-insured endorsement). The GC or owner named as additional insured can tender a lawsuit to your GL carrier.
A Palm Beach GC who asks to be additional insured on your rooftop-changeout subcontract is asking for coverage rights. Listing that GC only as certificate holder, or listing only CILB, does not accomplish it. Conversely, naming every GC as additional insured does not replace naming CILB as certificate holder for the license file.
Primary-and-noncontributory wording and a waiver of subrogation are common GC demands. They are contract insurance, not CILB insurance. Fail them and you may be off the site; fail CILB's holder language and you fail a Board audit.
Completed operations after a rooftop changeout
Premises and ongoing operations cover the job while you are on the roof: a wrench drops, a passerby is hurt, a curb is cracked while staging the old unit. Products-completed operations cover work after it is finished, put to its intended use, or abandoned. A changeout that is complete on Friday and dumps condensate into a ceiling on Monday is a completed-operations fact pattern, not a tools-in-hand operations claim.
If completed operations is excluded, sublimited, or already exhausted by the aggregate, the leak after you leave may be uninsured even though CILB saw $100,000 on the certificate the day you pulled the permit. Many owner specs require additional-insured status to include completed operations for a stated number of years. Read the endorsement schedule, not just the certificate description of operations.
Exclusions that surprise HVAC contractors: pollution and professional
Two exclusions sit on almost every GL form and map directly onto Florida HVAC work.
Pollution. Absolute or broadly worded pollution exclusions can bar damage arising from the discharge of vapors, fumes, chemicals, and contaminants. A refrigerant leak that contaminates a mechanical room, a grocery case, or an occupied suite may be argued as pollution, not ordinary property damage. Condensate overflow that produces mold is another frequent dispute. CILB's $25,000 property-damage minimum is not a pollution policy. If you recover, retrofit, or handle refrigerants daily, ask whether a contractors pollution endorsement or policy is on the form. Do not invent a premium; just know that the unendorsed GL may not respond.
Professional services. Design, engineering, and inspection services are commonly excluded from GL. Class A statutory scope includes design when not prohibited. A wrong equipment selection, an undersized duct design, or a faulty load calculation that you sealed as the qualifier can fall outside GL. That gap is why some firms buy professional liability on a claims-made form. Class B candidates still need the theory: the exclusion is about the nature of the service, not the tonnage limit.
Other recurring HVAC limitations: damage to your own work (you re-perform defective brazing; GL does not pay to redo it), care, custody, or control of property you are working on, auto accidents (that is the auto policy, not GL), workers' compensation (a ladder injury to your helper is Chapter 440, not GL), and contractual liability beyond the insured contract definition.
Advantages and limitations by coverage type
| Coverage | Advantage | Limitation |
|---|---|---|
| GL / public liability | Defends third-party injury and property damage from operations and, if included, completed operations | Pollution, professional, your-work, and employee-injury exclusions; CILB minimum may be far below contract limits |
| Property damage (CILB split) | Satisfies the Board's separate $25,000 HVAC aggregate | Does not convert GL into builders risk, inland marine, or pollution |
| Workers' compensation | Exclusive-remedy protection and statutory benefits for employees | Officer exemption is personal only; misclassified 1099 labor and uninsured subs become your problem under F.S. 440.10 |
| Commercial auto | Covers owned, hired, and non-owned vehicles between jobs | Does not cover tools in the van (inland marine) or the rooftop installation itself (GL / inland marine) |
| Inland marine / tools | Follows mobile equipment and copper off-premises | Deductibles, unattended-vehicle conditions, and scheduled versus blanket limits |
| Umbrella | Extra limit over GL and auto for catastrophic third-party claims | Follows underlying exclusions unless broadened; not a CILB substitute for missing primary coverage |
| Builders risk | Property coverage on the structure and installed materials during construction | Usually the owner's or GC's policy; may exclude existing-building service work and employee tools |
| Bid / performance / payment bonds | Lets you bid public and bonded work and protects the owner if you default | Surety, not insurance; the contractor indemnifies the surety; CILB HVAC certification does not require a licensing bond |
Florida HVAC scenarios: leak, ladder, and changeout
Refrigerant leak. After a Class B changeout in a Fort Lauderdale condo, a liquid-line joint fails overnight. Occupied units lose cooling, and leaked refrigerant and oil stain a mechanical closet. Completed-operations GL may address the stained building if property damage is covered and not excluded. A pollution exclusion can still defeat the contamination piece. Workers' compensation is not in play unless an employee was injured. The owner's HO-6 or condominium master policy may subrogate against you — additional-insured status, if the management company required it, changes who gets a defense.
Ladder injury. An installer falls from an extension ladder while recovering refrigerant on a Sarasota roof. If the installer is your employee, workers' compensation is the exclusive remedy against the employer for that injury; GL's employer-liability / employee-injury exclusion is why you do not run that claim through public liability. If the faller is an uninsured sub's helper, F.S. 440.10 can make that helper your statutory employee. A pedestrian on the ground hit by a dropped fitting is a GL operations claim, not WC.
Rooftop changeout. A Class A crew replaces a 30-ton packaged unit on a West Palm Beach strip center. During the lift, the old unit scrapes a neighboring rooftop HVAC curb (GL operations / property damage). After start-up, a crankcase heater you specified fails because of a design error (possible professional exclusion). Weeks later the new unit's condensate line backs up into the tenant below (completed operations). Tools stolen from the locked van overnight are inland marine, not GL. None of those events is paid by CILB's certificate-holder status. The Board cares that $100,000 / $25,000 remained in force in the exact business name; the claim file cares which grant and which exclusion apply.
On the B&F exam
When a question gives a dollar figure, ask first whether it is the HVAC CILB minimum or a contract limit. When it describes a claim, ask whether the trigger is occurrence or claims-made, whether the work was finished, whether the injured person is an employee, and whether pollution or professional language is in the fact pattern. Coverages and limitations — not a memorized premium — are what Area B item 8 tests.
A poorly brazed liquid line from a 2024 rooftop changeout fails in 2026 and stains a ceiling. The HVAC contractor's 2024 commercial general liability policy was an occurrence form that included completed operations, but the contractor now has a different carrier. Which statement is correct?
After a Fort Lauderdale changeout, refrigerant and oil contaminate a mechanical room. The contractor's certificate shows CILB's $100,000 / $25,000 HVAC minimums. Why might the claim still be unpaid?
A Palm Beach general contractor requires the HVAC subcontractor to add the GC as an additional insured with completed-operations coverage. Separately, Rule 61G4-15.003 requires a CILB certificate holder. Which statement is correct?
