HVAC, Electrical and Plumbing Contractor Insurance

In short

Electrical, plumbing and HVAC contractors usually carry general liability, workers’ compensation, commercial auto for service vans, tools and equipment coverage and a license bond. General contractors often require additional insured status, waiver of subrogation and primary and noncontributory wording. SF Coverage checks subcontracts and service agreements against your policies for free, confirms each GC certificate request matches your endorsements before your broker issues it and reviews workers’ comp audits before you pay.

Exposures to get right

Water and fire damage after the job

A failed fitting or wiring fault can damage a building months later, which makes completed operations coverage central.

Vehicles on the road all day

Service fleets drive constantly, and auto losses shape renewal pricing.

Class code mix at audit

Field and office payroll, and installation versus service work, can carry different workers’ comp rates.

In California

California requires workers’ compensation for every employer. CSLB C-20 HVAC licensees must already carry it even with no employees under SB 216.
Under SB 216 as amended by SB 1455 in 2024, all CSLB licensees, including electrical and plumbing classifications, must carry workers’ compensation from 1 January 2028.
The CSLB contractor license bond has been $25,000 since 1 January 2023.

Do HVAC contractors need workers’ comp without employees?

Yes for C-20 licensees. Under SB 216, CSLB requires C-20 HVAC licensees to carry workers’ compensation even with no employees. Electrical and plumbing licensees without employees can still claim the exemption until 1 January 2028, when the requirement extends to all licensees under SB 1455. Check your status on the CSLB website.

What do general contractors usually ask subs for?

Most subcontracts ask for general liability with additional insured status for ongoing and completed operations, a waiver of subrogation, primary and noncontributory wording, workers’ compensation and auto limits. SF Coverage reads your subcontract against your actual endorsements so you know what is missing before you sign.

How fast can I get a certificate for a new GC?

Send the GC’s request and your policies by 3 pm Pacific and SF Coverage checks it the same business day, confirming the additional insured, waiver and primary wording are actually endorsed. Any missing endorsement is requested from the insurer the same business day and followed up every two business days until it is issued.

Why does my workers’ comp audit keep coming back high?

Audits often move payroll into higher rated class codes, count uninsured subcontractors as employees or miss overtime splits. SF Coverage reviews the audit worksheet against your payroll records before you pay and prepares a clear dispute when the classification or numbers are wrong.

What should a trade contractor send for a subcontract check?

The subcontract or master agreement, the GC’s insurance exhibit and your current declarations and endorsement schedules. SF Coverage cites every requirement to its clause and checks the additional insured, waiver and primary wording against your policy, so any gap is named before you mobilize.

General information. Coverage depends on the policy an insurer issues.
