Insurance for HVAC, directional boring and IT contractors
Your contracts are written by the owner's lawyer and your policy by an insurer's. We read both — and close the distance between what you promised and what you're covered for.
Schedule a Coverage AuditWhy do contractors need more than a standard general liability policy?
A contractor's general liability policy covers bodily injury and property damage, but the exposures that produce the largest contractor losses — pollution, underground damage, professional design errors, equipment in transit, and liability assumed in contracts — are commonly excluded or limited by endorsement. Owners, general contractors and municipalities also require specific additional insured, primary and non-contributory, and waiver of subrogation wording that must appear in the policy, not just on the certificate. Matching the policy to your contracts and your actual work is the job.
The contract review we perform for every contractor client:
| Contract requirement | What to confirm in the policy |
|---|---|
| Additional insured — ongoing and completed operations | Endorsements that cover both (e.g., ISO CG 20 10 and CG 20 37 or equivalents), and how long completed-operations status lasts |
| Primary and non-contributory | Specific endorsement language; not satisfied by a certificate note |
| Waiver of subrogation | Blanket waiver on GL, auto, workers' compensation and umbrella |
| Per-project aggregate | Separate aggregate limits per job so one loss does not exhaust coverage for others |
| Indemnity / hold harmless | Contractual liability coverage for the indemnity you signed; Michigan's anti-indemnity statute limits some construction indemnities |
| Umbrella "follow form" | The umbrella extends additional insured status and doesn't add new exclusions |
What insurance risks do large commercial HVAC contractors face?
Large commercial HVAC and mechanical contractors face hot-work fires, water damage from failed piping and condensate lines, refrigerant and mold pollution claims, crane and rigging losses on high-value rooftop equipment, design-assist professional liability, and large vehicle fleets. Most of these sit at the edges of a standard contractors policy. The right program adds contractors pollution liability, an installation floater, riggers liability, contractors professional liability and fleet-grade commercial auto.
Exposures specific to commercial HVAC:
- Hot work. Brazing and torch work is a leading cause of contractor-caused fires. Underwriters ask about hot-work permits and fire watch; carrying a documented program helps both safety and pricing.
- Water damage. Chiller, hydronic and condensate failures can damage multiple floors of tenant space. Check for water-damage sublimits or exclusions on your GL.
- Refrigerants and pollution. The EPA's HFC phase-down has moved new equipment toward A2L (mildly flammable) refrigerants, which changes handling, storage and training. Refrigerant releases, mold from HVAC moisture, and Legionella from cooling towers are pollution claims — excluded from GL and covered by contractors pollution liability (CPL).
- Rigging and cranes. Damage to a customer's rooftop unit or chiller while you lift it is "property in your care" and excluded from GL; riggers liability covers it. Crane rental agreements often shift full liability to you.
- Equipment before acceptance. Units delivered to site and not yet accepted by the owner need an installation floater or builders risk.
- Design-assist and controls. Sizing equipment, designing ductwork, or programming building automation creates professional liability that GL excludes.
- Service agreements. Preventive maintenance contracts create long-tail completed-operations exposure and, for connected building controls, cyber exposure.
| Coverage | Trigger | Friction | Boundary |
|---|---|---|---|
| Contractors pollution liability | Release of refrigerant, mold or other contaminant from your work | Occurrence vs. claims-made; when mold "began" | Known conditions; fines and penalties |
| Riggers liability | Damage to customer property while lifting or moving it | Valuation of custom equipment; who controlled the lift | Mechanical breakdown of the item itself |
| Installation floater | Physical loss to equipment in transit, stored or installed before acceptance | Whether the owner's builders risk is primary | Testing and commissioning damage, depending on form |
| Contractors professional liability | Error in design, sizing or controls programming | Distinguishing design error from faulty installation | Work performed by uncovered design subcontractors |
What insurance does a directional boring (HDD) contractor need?
A horizontal directional drilling contractor needs general liability with no explosion, collapse or underground (XCU) exclusion, specific coverage for underground utility damage, contractors pollution liability for drilling-fluid releases, an equipment floater for drill rigs and tooling — including tools lost downhole — and the additional insured and permit requirements of road commissions, utilities and railroads. Underground utility strikes are the defining loss: one fiber or gas line strike can produce repair costs, business interruption claims from the utility's customers and, in the worst case, an explosion.
Michigan's MISS DIG Underground Facility Damage Prevention and Safety Act requires notice to MISS DIG 811 before excavating, and records of tickets, locates and marks are the first documents requested after a strike. Exposures and how they are covered:
- XCU exclusions. Some GL policies exclude or restrict explosion, collapse or underground damage for excavation classes. For an HDD contractor, that exclusion removes the core exposure — it must be absent or deleted.
- Fiber and telecom strikes. Cutting a fiber backbone generates repair costs plus loss-of-use claims. High per-occurrence limits and umbrella capacity matter more than for most trades.
- Frac-outs (inadvertent returns). Drilling fluid surfacing in a stream, wetland or basement is a pollution event; GL's pollution exclusion applies. CPL responds, and permits from environmental regulators often specify response obligations.
- Downhole tools. Equipment floaters commonly exclude tools lost or stuck in the bore. "Tools in the hole" coverage must be added specifically.
- Rights-of-way. Municipal, county road commission and MDOT permits require additional insured status; railroad crossings may require railroad protective liability.
- Subcontracted fiber builds. Broadband and utility programs flow down strict insurance terms through prime contractors; we review those before you bid.
| Coverage | Trigger | Friction | Boundary |
|---|---|---|---|
| GL without XCU exclusion | Damage to underground utilities or property from boring | Locate accuracy; whether the line was marked correctly | Damage you knew of; work without a valid locate ticket may be contested |
| Contractors pollution liability | Drilling-fluid release or contamination | Classification of bentonite or additives as "pollutants" | Regulatory fines; known conditions |
| Contractors equipment floater | Loss or damage to rigs, mud systems and locating equipment | Valuation (actual cash value vs. replacement) | Tools in the hole unless added; wear and mechanical breakdown |
| Railroad protective liability | Work within railroad right-of-way | Railroad-specific forms and approvals | Work outside the scheduled location |
What insurance does an IT contractor or managed service provider need?
IT contractors and managed service providers need technology errors and omissions (tech E&O) and cyber liability — usually combined on one policy — because general liability excludes professional services and damage to electronic data. An MSP holds privileged access to many clients' networks at once, so a single compromise of its tools can become a breach at every client. Low-voltage and cabling installers add jobsite exposures: property damage from drilling, ladder and lift injuries, and installed equipment before acceptance.
The IT contractor exposures we address:
- Failure to perform. A migration that corrupts data, a missed backup, a misconfigured firewall. Tech E&O responds to your client's financial loss; GL does not.
- Aggregation through privileged access. Remote monitoring and management tools are high-value targets; attacks on MSP tools have historically spread to many downstream businesses at once.
- Contracts. Master service agreements with limitations of liability, indemnities and SLA credits. Tech E&O usually won't cover SLA credits or liability you assumed only by contract.
- Defense-sector clients. IT providers that store, process or transmit CUI for defense contractors may be in CMMC scope as an external service provider. See Cyber Risk & CMMC.
- Social engineering. Fraudulent wire instructions sent from a compromised client or vendor mailbox; covered by crime or cyber only when specifically included.
- Cabling and installation. Drilling into concealed pipes, sprinkler heads struck by lifts, and equipment theft from jobsites belong on GL, inland marine and workers' compensation.
| Coverage | Trigger | Friction | Boundary |
|---|---|---|---|
| Technology E&O | Client financial loss from your error, omission or failure to perform | Scope of services in the MSA vs. what the client expected | Contractual penalties and SLA credits; bodily injury |
| Cyber (first- and third-party) | Breach of your systems or attack using your tools | Whether client systems count as "your computer system" | Infrastructure outages beyond your control, depending on form |
| Crime / social engineering | Fraudulent funds transfer induced by deception | Verification procedures required by the policy | Losses without call-back verification, under some wordings |
| GL & inland marine | Physical damage or injury on jobsites; equipment in transit | Electronic data exclusions on GL | Professional errors; data loss |
How can contractors reduce insurance costs and improve their bonding position?
Contractors reduce insurance costs by lowering claim frequency in the lines that cost the most — workers' compensation and commercial auto — and by documenting controls underwriters care about: written safety programs, telematics and driver standards, hot-work and lift plans, locate-ticket discipline and subcontractor certificate management. Michigan workers' compensation premiums are adjusted by an experience modification factor, so preventing a few lost-time injuries can change costs for three years. Clean financials and documented controls also strengthen surety relationships for bid and performance bonds.
Subcontractor management deserves its own line item: collecting certificates is not enough. We help you require — and verify — additional insured endorsements, adequate limits and current workers' compensation from every sub, so their losses don't become yours.
