Answer-first summary: Inland marine insurance covers the tools, equipment, refrigerants, and materials HVAC contractors transport to and use on job sites — property that a standard commercial property policy excludes once it leaves your shop. Coverage typically costs $600–$2,000 per year for small-to-mid-size HVAC firms and fills the critical gap between your building policy and your commercial auto policy.
Who this is for: HVAC contractors, sheet metal and refrigeration mechanics, mechanical subcontractors, and HVAC service companies that carry tools and equipment between a shop and multiple job sites.
TL;DR — Key Takeaways
- Your commercial property policy covers contents at your listed address only; inland marine covers the same tools and materials while they are in transit or at a job site.
- HVAC contractors need at minimum a Contractors Equipment Floater (owned tools and machines) and often an Installation Floater (refrigerant, ductwork, and equipment being installed but not yet accepted by the customer).
- Typical annual premiums run $600–$2,000 for a small residential HVAC shop; larger commercial mechanical firms with $200,000+ in equipment values can pay $3,000–$7,000/year.
- Replacement cost (RC) valuation costs more than actual cash value (ACV) but avoids depreciation shocks when a $4,500 recovery machine is stolen from a van.
- A single inland marine policy can schedule multiple coverage sub-limits — blanket tools, scheduled high-value equipment, and an installation floater — keeping your program clean.
What Does Inland Marine Cover for HVAC Contractors?
Despite the name, inland marine has nothing to do with water. It evolved from marine cargo law to cover property in transit on land. For HVAC contractors, three sub-coverages matter most:
| Coverage Type | What It Protects | Typical Limit Range |
|---|---|---|
| Contractors Equipment Floater | Owned tools, test instruments, refrigerant recovery machines, manifold gauge sets, vacuum pumps, pipe benders, ladders | $25,000–$500,000 |
| Installation Floater | Materials and equipment you've purchased for a specific project — condensing units, air handlers, ductwork — while they are on-site but not yet accepted | Per-project or annual blanket; $50,000–$2M |
| Leased/Rented Equipment | Equipment you temporarily lease (scissor lifts, boom lifts, cranes for rooftop units) | Often added by endorsement; $25,000–$100,000 |
| Employee Tools Rider | Tools owned by your employees and used on your jobs | $1,000–$5,000 per employee sub-limit |
What inland marine does NOT cover (common exclusions): - Wear and tear or mechanical breakdown of equipment - Tools left unsecured in an unlocked vehicle overnight (many carriers require locked vehicle or locked storage) - Employee theft by a dishonest employee (that's crime/fidelity coverage) - Damage to the company truck itself — the vehicle is covered by commercial auto, not inland marine (your equipment floater still covers the tools inside while in transit; verify with your carrier how these coordinate) - Finished HVAC systems after the customer has accepted the work (now covered by the building owner's property policy or your completed-operations liability)
How Much Does Inland Marine Cost for HVAC Contractors?
Premium is driven by total insured value (TIV), deductible, valuation basis (ACV vs. RC), territory, and loss history.
| Contractor Profile | Equipment TIV | Annual Premium Estimate |
|---|---|---|
| 1-truck residential service tech | $15,000–$30,000 | $600–$950/year |
| 3-truck residential replacement company | $50,000–$100,000 | $950–$1,800/year |
| Commercial HVAC subcontractor (5–10 field crews) | $150,000–$350,000 | $2,500–$5,500/year |
| Large mechanical contractor (sheet metal fab + field) | $500,000+ | $5,000–$12,000+/year |
These ranges are industry-typical estimates, not quotes. Your actual premium depends on carrier, loss history, security measures, and the specific equipment schedule. Contact Morrow for a bindable number.
Ways to reduce premium: - Choose a higher deductible ($1,000 instead of $250) - Install GPS tracking on high-value equipment - Document a formal tool check-in/check-out log (demonstrates controls) - Combine with your general liability and commercial auto under one carrier for a package discount
Contractors Equipment Floater vs. Installation Floater — Which Do You Need?
Many HVAC contractors need both, and confusing them leads to uncovered losses.
A Contractors Equipment Floater covers your durable, reusable tools — the equipment your crews carry every day. It follows the equipment wherever it goes.
An Installation Floater covers materials and equipment you've purchased for a specific project and are storing on-site or staging for installation. Once the customer accepts the completed system (typically evidenced by a certificate of completion or final inspection), the installation floater's job is done and the building owner's property policy takes over.
Example gap without an installation floater: You deliver three rooftop units to a commercial building on a Friday afternoon — $42,000 in equipment. Over the weekend, thieves steal two of them. Your contractors equipment floater won't respond (you don't own rooftop units as reusable equipment — you bought them for this job). Your commercial property policy won't respond (the units aren't at your shop). Without an installation floater, you absorb the full loss.
How to Get Inland Marine Coverage as an HVAC Contractor — 5 Steps
-
Inventory your equipment and tools. List every item by description, purchase year, purchase price, and current replacement cost. Include refrigerant recovery machines, manifold gauges, vacuum pumps, leak detectors, pipe threading machines, ladders, hand tools, and any rented-to-own equipment. This becomes your "schedule" for high-value items and your blanket total for the floater.
-
Identify your installation floater needs. If you carry inventory for projects — condensing units, air handlers, coils, ductwork — estimate your maximum on-site value at any one time. That figure drives your per-occurrence installation floater limit.
-
Choose ACV or replacement cost valuation. Replacement cost is almost always worth the modest additional premium for HVAC equipment, which depreciates quickly. A five-year-old refrigerant recovery machine with an ACV of $800 may cost $3,200 to replace.
-
Set your deductible. Common choices are $250, $500, or $1,000. A $1,000 deductible meaningfully reduces premium; just ensure you can absorb that out-of-pocket on a bad week.
-
Bundle and bind. Work with a commercial P&C agent (like Morrow) who can place the inland marine alongside your general liability, commercial auto, and workers' compensation so certificates of insurance (COIs) reflect all lines and any waiver-of-subrogation or additional-insured requirements on contracts are handled cleanly.
Real-World Scenario: A Dallas HVAC Contractor's Equipment Theft Claim
The following is an illustrative example showing how coverage typically works. It is not a guarantee of coverage or claim outcome.
Setup: A three-truck residential HVAC replacement company in the Dallas–Fort Worth metro carries a Contractors Equipment Floater with a $75,000 blanket limit, replacement cost valuation, and a $500 deductible.
Incident: A crew parks an unmarked service van overnight at a staging yard. Thieves break in and take a Fieldpiece refrigerant recovery machine ($1,850 replacement cost), a digital manifold gauge set ($890), a micron gauge ($220), and a full set of hand tools ($2,400). Total replacement cost: $5,360.
Claim outcome: The contractor files a police report and submits receipts or equivalent documentation. The carrier pays $5,360 minus the $500 deductible — $4,860 net recovery — and the contractor replaces the equipment and is back running full crews within a week.
Without inland marine: The commercial property policy excludes contents away from the listed premises. The commercial auto policy covers vehicle damage, not the cargo inside. The contractor would absorb the full $5,360 loss out of pocket.
Texas-specific note: Texas does not mandate inland marine for HVAC contractors by statute, but many commercial general contractors and property managers require proof of inland marine coverage — along with a waiver of subrogation in their favor — in their subcontractor agreements.

Frequently Asked Questions
Does my commercial property policy cover tools at job sites? No. A standard commercial property (building and business personal property) policy covers contents at the "described premises" listed on the declarations page — typically your office or shop. Once tools leave that location, they are generally uninsured under the property policy. Inland marine fills this gap.
Does commercial auto cover tools stolen from my work truck? Generally, no. Commercial auto covers the vehicle itself (collision, comprehensive) and liability arising from its use. Tools and equipment inside the vehicle are not covered under a standard commercial auto policy — that requires either an inland marine floater or a specific cargo endorsement. Always confirm with your carrier how the two policies coordinate.
What's the difference between blanket and scheduled coverage? A blanket limit (e.g., $50,000 for all tools) covers your entire pool of equipment up to that cap without listing each item. Scheduled coverage lists specific high-value items (e.g., "Appion G5 Twin recovery machine, serial #XYZ, RC value $2,800") and insures each at that stated value. Most HVAC inland marine policies use a combination: blanket for hand tools under a per-item threshold and scheduled for high-value machines.
Is refrigerant covered under inland marine? Refrigerant in transit or stored on a job site can be covered under an inland marine policy, but carriers vary. Some treat refrigerant cylinders as equipment; others require it to be added by endorsement. Given the cost of R-410A and R-32 refrigerant, ask your agent specifically about refrigerant coverage and any quantity limits.
Do I need an installation floater if I carry builders risk on my projects? Builders risk is typically purchased by the property owner or general contractor and covers the project structure and permanently incorporated materials during construction. As a subcontractor, you may not have an insurable interest in a builders risk policy, and even if named, coverage on equipment and materials you own before installation may be limited. An installation floater is your own policy, protecting your property until the customer accepts the work.
Will inland marine cover my employees' personal tools? Standard contractors equipment floaters cover tools owned by your business. Personal tools owned by employees are typically excluded — but many carriers offer an employee tools rider (sub-limit, often $1,000–$3,000 per employee) that can be added. If your employment agreement requires you to cover employee tools, confirm this endorsement is in place.
How quickly can I get a certificate of insurance showing inland marine? With Morrow, COIs are typically issued same-day for existing policies, often within minutes through our online portal. For new policies mid-project (e.g., a GC demands proof before you start), we prioritize same-day binding.
What deductible should an HVAC contractor choose? For a one- or two-truck operation, a $500 deductible balances cost and affordability. For larger firms with strong cash flow and good tool controls, a $1,000 deductible can reduce premium by 10–20%. Avoid sub-$250 deductibles — the premium savings are minimal and may encourage nuisance claims that affect your loss history.
