HVAC Commercial Auto Insurance
Call Us: 603-766-3733
Running an HVAC business in New Hampshire means your fleet is your lifeline. Whether your technicians are hauling refrigerant across Concord in January or driving box trucks loaded with ductwork up to the Lakes Region in July, those vehicles face risks that a standard auto policy simply won't cover. The commercial auto insurance market in NH has been tightening, with statewide premiums
climbing from $209 million in 2023 to $233 million in 2024 - an 11.5 percent jump in a single year. For HVAC contractors specifically, the stakes are even higher because your vehicles carry expensive equipment and your technicians drive in some of the worst winter conditions in the Northeast. Getting the right commercial auto coverage in New Hampshire requires understanding what's actually available, which carriers want your business, and how claims play out in this state's unique environment. Generic policies built for office fleets won't cut it here. HVAC contractors need coverage shaped around their actual operations: the tools bolted inside service vans, the apprentice driving a personal truck to a job site, and the seasonal spikes in road hazards that make December through March a claims minefield. Here's what you need to know to protect your fleet and your bottom line.
Essential Commercial Auto Coverage for NH HVAC Fleets
HVAC fleets aren't like delivery vans or sales rep sedans. Your vehicles serve double duty as rolling workshops, and the coverage you carry needs to reflect that reality. A single service van might hold $15,000 to $40,000 in tools, diagnostic equipment, and refrigerant inventory on any given day. The right policy accounts for all of it.
Liability Limits and NH State Minimum Requirements
New Hampshire is one of the few states that doesn't mandate auto insurance for personal vehicles, but commercial vehicles are a different story. If you're operating a fleet for business purposes, you need liability coverage, and the state minimums (25/50/25) are dangerously low for an HVAC operation. One serious accident involving a loaded service truck could easily exceed $100,000 in damages and medical costs.
Most HVAC contractors should carry at least $1 million in combined single-limit liability. If your trucks are regularly on highways or working near residential properties, consider going higher. An umbrella policy can fill the gap between your auto liability limits and the actual exposure your business faces. The cost difference between minimum coverage and $1 million CSL is often surprisingly small relative to the protection it provides.
Inland Marine vs. Auto: Protecting Specialized Tools and Inventory
Here's a coverage gap that catches many HVAC business owners off guard: your commercial auto policy typically covers the vehicle itself, but the tools, equipment, and materials inside it often fall into a gray area. A standard auto policy might offer $1,000 to $5,000 in coverage for contents. That doesn't come close when you're carrying recovery machines, manifold gauges, vacuum pumps, and cylinders of R-410A.
Inland marine insurance fills this gap. It covers tools and equipment in transit or stored on a job site, regardless of whether they're in the vehicle at the time of loss. Some contractors try to stretch their auto policy to cover everything, but a dedicated inland marine endorsement or standalone policy is almost always the smarter play.
| Coverage Type | What It Covers | Typical Limit | Best For |
|---|---|---|---|
| Commercial Auto (contents) | Tools/materials inside vehicle at time of loss | $1,000 - $5,000 | Basic hand tools only |
| Inland Marine | Tools, equipment, materials in transit or on-site | $25,000 - $100,000+ | Full tool inventory, diagnostic equipment |
| Equipment Floater | Specific scheduled high-value items | Per-item basis | Recovery machines, brazing kits, leak detectors |
Hired and Non-Owned Auto Liability for Technicians
If any of your technicians ever drive their personal vehicles to a job site, or if you rent a truck during peak season, you have an exposure that your standard commercial auto policy won't touch. Hired and non-owned auto (HNOA) liability covers your business when employees use vehicles you don't own for work purposes.
This comes up constantly in HVAC operations. A tech picks up parts from a supply house in their own car. A seasonal helper drives their truck to a residential install. If they cause an accident while on company business, your business gets named in the lawsuit. HNOA coverage is inexpensive relative to the risk it addresses, and most carriers will add it as an endorsement to your existing policy.

Carrier Appetite and Risk Assessment in the New Hampshire Market
Not every insurance carrier wants to write HVAC commercial auto. The combination of heavy vehicles, specialized cargo, and winter driving makes this a class of business that some underwriters avoid entirely. Understanding which carriers are actively writing this coverage in New Hampshire saves you time and often money.
Preferred Carriers for HVAC Service and Installation Fleets
The New Hampshire commercial auto market is concentrated: 36 affiliated groups account for 90 percent of all commercial auto premiums written in the state. That concentration means a handful of carriers dominate, and their appetite for contractor fleets varies significantly. Some focus on long-haul trucking, others on light commercial vehicles.
For HVAC fleets specifically, you'll find the best pricing and coverage terms from carriers that specialize in contractor classes. These insurers understand the difference between a plumber's van and an HVAC installation truck, and they price accordingly. An agency like Avery Insurance Agency, which has spent over 125 years building carrier relationships in New Hampshire, can match your fleet profile to the carriers most likely to offer competitive terms. Working with an agency that knows which underwriters have appetite for your specific operation makes a measurable difference in both premium and coverage quality.
Impact of Fleet Size and Vehicle Type on Underwriting
Underwriters look at your fleet through a specific lens. A three-van operation with clean driving records is a very different risk than a twelve-truck fleet with box trucks and trailers. Vehicle weight matters: anything over 10,000 pounds GVW triggers different rating tiers and often requires higher liability limits.
The mix of vehicle types in your fleet also affects pricing. Service vans rated for light commercial use are cheaper to insure than heavy-duty trucks used for installation work. If you're running a combination of both, expect underwriters to rate each vehicle class separately. Fleet size can work in your favor, though. Carriers often offer volume discounts starting at five vehicles, and the
estimated market-wide combined ratio of 85 percent in 2024 suggests New Hampshire's commercial auto market remains profitable enough for carriers to compete for well-managed fleets.
New Hampshire's climate and geography create a claims environment that's distinct from most other states. Your fleet faces hazards that underwriters in warmer states don't even think about, and how you handle claims after an incident matters as much as the coverage you carry.
Winter Driving Risks and Seasonal Claim Trends
From November through March, your technicians are driving on roads that regularly feature black ice, heavy snow, and reduced visibility. Emergency heating calls spike during the coldest weeks, which means your drivers are out in the worst conditions precisely when roads are most dangerous. Claims data in New Hampshire consistently shows a seasonal spike in collision and comprehensive claims during winter months.
Frozen roads in the White Mountains region and icy secondary roads throughout the Merrimack Valley are particularly treacherous for loaded service vans with high centers of gravity. Comprehensive coverage for weather-related damage (falling ice, tree limbs, road debris) is essential, not optional, for any NH HVAC fleet.
Claims Procedures for Specialized Refrigerant and Equipment Damage
A fender bender is straightforward. A rollover that ruptures refrigerant cylinders in the back of your van is not. Refrigerant spills can trigger environmental cleanup requirements, and the cost of lost inventory adds up fast when you're carrying multiple cylinders of R-410A or R-454B.
When filing a claim involving specialized equipment or hazardous materials, document everything immediately: photographs of the vehicle interior, inventory lists, and any environmental response costs. Your adjuster needs to understand that the cargo in an HVAC van isn't comparable to office supplies. Having an insurance partner who understands these claim nuances, someone who can advocate for proper valuation of your specialized equipment, makes the difference between a fair settlement and a frustrating shortfall.
With commercial auto rates increasing 10 to 30 percent nationally and that trend expected to continue through 2026, controlling your premiums requires proactive risk management. Carriers reward businesses that demonstrate they take fleet safety seriously.
Telematics and Driver Safety Training for Technicians
Installing telematics devices in your fleet vehicles gives you real-time data on speeding, hard braking, and route efficiency. More importantly, it gives your carrier data that can justify lower premiums. Many insurers offer 5 to 15 percent discounts for fleets with active telematics programs.
Pair telematics with annual driver safety training that covers winter driving techniques, load securement for equipment, and defensive driving in residential neighborhoods. Your technicians aren't professional drivers - they're skilled tradespeople who happen to drive for work. Training that acknowledges this distinction tends to be more effective than generic safety videos.
MVR Monitoring and Employment Screening Standards
Pulling motor vehicle records once a year isn't enough. Continuous MVR monitoring catches license suspensions, DUI charges, and accumulating violations between annual checks. One technician with a suspended license driving your company van creates an exposure that could void your coverage entirely.
Set clear hiring standards for driving records. Most carriers prefer that you exclude drivers with more than two moving violations in three years or any DUI within five years. These standards protect your insurability and keep your premiums in check. Businesses that
bundle their general liability with commercial auto coverage can potentially save 12 to 18 percent annually, but only if the underlying risk profile supports it.
Selecting a Specialized NH Commercial Insurance Partner
The right insurance partner for your HVAC fleet isn't the one with the flashiest website or the lowest initial quote. It's the one who understands your trade, knows which carriers have appetite for contractor fleets in New Hampshire, and can advocate for you when a claim gets complicated. HVAC contractors need coverage built specifically for their trade, not generic commercial policies stretched to fit.
Avery Insurance Agency takes a consultative approach to commercial auto coverage for HVAC businesses, identifying vulnerabilities that generic quotes miss: the gap between auto and inland marine coverage, the HNOA exposure from technicians using personal vehicles, the seasonal risk adjustments that New Hampshire's climate demands. With roots in the state going back to 1899, they understand both the local market and the carrier relationships that produce better outcomes. If your current policy feels like it was designed for someone else's business, it probably was. A conversation with a specialist who knows NH HVAC operations inside and out is the fastest way to find out what you're missing.
Frequently Asked Questions
Does New Hampshire require commercial auto insurance for HVAC contractors? While NH doesn't mandate personal auto insurance, commercial vehicles used for business must carry liability coverage. Most contracts and licensing requirements also demand proof of insurance.
How much does commercial auto insurance cost for a small HVAC fleet in NH? A fleet of three to five service vans typically runs $3,000 to $8,000 annually per vehicle, depending on driver records, vehicle types, and coverage limits. Rates vary significantly by carrier.
Will my commercial auto policy cover tools stolen from my van? Usually only up to a very low limit, often $1,000 to $5,000. An inland marine policy or equipment floater provides proper coverage for your full tool inventory.
Can I save money by bundling my HVAC business insurance policies? Yes. Bundling general liability, commercial auto, and other coverages into a package or BOP can reduce total premiums by 12 to 18 percent with many carriers.
What happens if a technician gets in an accident driving their personal car to a job? Your business could be liable. Hired and non-owned auto coverage protects against this specific exposure and is one of the most commonly overlooked endorsements for HVAC contractors.

Got Questions? We’ve Got Answers.
Straight Answers From the Advisors Who Know This State Best
What does it mean that Avery is an independent insurance agency?
An independent agency like Avery is not tied to any single insurance company. We represent multiple top-rated carriers, which means we can shop the market on your behalf and recommend the coverage that truly fits your needs — not the one that benefits any single insurer.
This independence gives you access to more options and unbiased advice. Our advisors are compensated to serve your interests, not to push a specific product. That is a significant advantage over captive agents who can only offer one carrier’s policies.
How much does it cost to work with an Avery advisor?
There is no direct cost to you for working with an Avery advisor. Independent agents are compensated through commissions paid by the insurance carriers when a policy is placed. You receive expert guidance, market comparisons, and ongoing service at no extra charge.
In fact, many clients find that working with Avery saves them money. Our advisors know how to identify the right coverage levels so you are not paying for protection you do not need, and you are not left exposed where you do.
Does Avery help with claims?
Yes — and this is one of the most important things that sets Avery apart. When you have a claim, our in-house claims advisors go to work for you. We guide you through the process, communicate with the insurance company, and advocate for a fair and timely outcome.
Several of our team members hold professional claims designations, including AIC and AINS. We do not just help you file paperwork — we actively represent your interests to make sure you receive the full benefit your policy provides.
Where in New Hampshire does Avery provide coverage?
Avery serves clients throughout the state of New Hampshire from our offices in Wolfeboro and Portsmouth. Whether you live in the Lakes Region, the Seacoast, the White Mountains, or the Merrimack Valley, an Avery advisor is ready to help you find the right coverage.
Our advisors understand the specific risks that come with living and doing business in New Hampshire — from harsh winter weather to seasonal watercraft exposure. We apply that local knowledge to every coverage recommendation we make.
How does Avery handle high-value homes and assets?
Avery offers a dedicated Premier Client Services program for clients with homes valued over .5 million, significant investment portfolios, fine art collections, jewelry, yachts, and other complex assets. This program pairs you with a specialist who understands the unique risks of high-net-worth households.
Through carriers that specialize in high-value personal lines, we provide guaranteed replacement cost coverage, agreed value policies, and comprehensive risk management strategies. Your advisor will conduct a detailed review of your full asset portfolio to make sure nothing is overlooked or underinsured.
How often should I review my insurance coverage?
Avery recommends a full coverage review at least once a year. Major life events — buying a home, starting a business, adding a vehicle, getting married, or making significant home improvements — are all good triggers for an immediate review outside your annual cycle.
Insurance needs change over time, and policies that were right for you a few years ago may leave gaps today. Avery advisors proactively reach out to clients for annual reviews and keep up with changes in the insurance market that could affect your coverage or premium. Our goal is to make sure you are always protected and never paying for coverage that no longer fits.
