The insurance the Texas HVAC agency requires.

Usually not. The minimum exists so a license can issue, and the department’s form says plainly that the certificate is issued as a matter of information only, confers no rights on the holder, and neither amends nor alters the coverage the policy affords. Property managers, general contractors, and facilities teams set their own requirements in the insurance exhibit, and they commonly ask for higher per-occurrence and aggregate limits, additional insured status, and waivers. We write the policy for the contracts you sign and issue the department’s certificate from the same policy, so one set of limits satisfies both.

Because the class is wider. Class A entitles the holder to contract for systems, products, and equipment of any size or capacity, so the work reaches rooftop units, mechanical rooms, and process loads. Class B is limited to the statutory tonnage and heating output, which is residential and light commercial. The department’s form reflects that with a higher per-occurrence amount, a higher products and completed operations aggregate, and a higher general aggregate for Class A. If you move from Class B to Class A, the certificate on file has to move with you.

Evidence of insurance is one of the conditions the statute names for issuing the license, and the department’s form asks the carrier to notify it before a cancellation or non-renewal and shortly afterward if that is not possible. In practice a lapse puts the license in question, and a shop cannot afford to find that out at a permit desk. That is why we calendar the policy period and file the replacement certificate before the current one expires, rather than waiting for a notice to arrive.

No. The form states that it is issued to the department as a matter of information only, that it confers no rights upon the certificate holder, and that it neither affirmatively nor negatively amends, extends, or alters the coverage afforded by the policy. It also says the terms of the insurance policy control over the terms of the certificate. That is the same rule every certificate follows: the policy and its endorsements do the work, and the certificate is the evidence. It is why we get the policy right before we issue any certificate.

The insurance the department collects on this form is general liability. Workers’ comp in Texas is elective for most private employers, and the Department of Insurance rather than the licensing agency is the authority on it, so an air conditioning and refrigeration license does not turn on it. Public work and most general contractors do require workers’ comp in the contract, which is where the decision usually gets made for you. We put that decision on the record either way, with the contracts you sign in view.

The department’s form asks for the insurance company, the policy number, and the term dates, and for an authorized insurance representative to certify that the policy meets or exceeds the stated minimums. It does not publish an admitted-only rule on the form itself. For HVAC shops the admitted market will not write at a given moment, that matters, and we confirm acceptability with the department before we rely on it rather than guessing. What does not change is the substance: the limits on the form are the floor, and the policy has to actually carry them.
