The plumbing & HVAC insurance checklist

QUICK ANSWER

A plumbing or HVAC business needs general liability with completed operations, workers' compensation once it has employees, commercial auto for service vans, and tools and equipment coverage. Water damage and refrigerant handling make completed operations and pollution coverage more important than for most trades, and property managers add additional insured and waiver requirements.

How to check what you already have

  1. General liability dec page. Each occurrence, general aggregate and the products–completed operations aggregate. Confirm no endorsement limits water damage or completed operations.
  2. Forms list. Blanket additional insured for ongoing and completed operations, blanket waiver of subrogation, primary and non-contributory.
  3. Pollution. Either a separate contractors pollution policy or a limited pollution endorsement on the GL; know which you have and what it excludes.
  4. Workers' compensation. Information page lists every state you work in.
  5. Auto and tools. Every van scheduled; recovery machines and diagnostic equipment on a tools schedule.

What usually goes wrong

  • "Your work" exclusion surprises. Redoing your own defective work is not covered; the damage it causes to the rest of the building is. Owners often expect the reverse.
  • Mold. Many policies exclude it entirely. A pollution policy with mold coverage is the fix for contractors who open walls.
  • Driver lists. New hires driving vans before they are added to the auto policy.
  • Seasonal payroll swings. An HVAC payroll estimate set in winter produces a painful audit after a hot summer.

Renewal timing

Start sixty days before the earliest expiration. Bring the year's actual payroll and receipts so the renewal application and the audit match, and ask for the completed-operations and pollution limits your largest current contract requires.

Questions people actually ask

Does my general liability cover water damage from my work?

Generally yes for damage to others' property caused by your work, through the completed-operations part of the policy. It does not cover redoing your own faulty work, and some policies narrow water damage, so read the forms.

Why do property managers want a waiver of subrogation?

If a leak you caused damages the building and the building's insurer pays, that insurer would normally come after you. A waiver on the manager's side of the deal and additional insured status on yours sort out who pays without litigation.

Is refrigerant handling a pollution exposure?

Insurers treat releases of refrigerant, fuel oil and similar substances as pollution, and standard general liability excludes most pollution claims. A contractors pollution policy fills the gap and is increasingly required on commercial work.

What is the difference between a service plumber and a new-construction plumber to a carrier?

Classification and price. Service and repair work is rated differently from new construction and remodeling. Describe the real mix of work so the policy matches it and the audit holds no surprises.
