The price you pay is the same whether you buy direct or through a broker — carriers pay the broker's commission, not you.

Running an HVAC contracting business means managing significant risks daily. From installing commercial cooling systems on rooftops to servicing residential furnaces in tight crawl spaces, your technicians face property damage exposure, injury risks, and potential professional liability claims. Choosing between Hartford and Chubb for your HVAC contractor insurance can mean the difference between comprehensive protection and costly coverage gaps.

Both carriers offer specialized coverage for HVAC contractors, but they target different market segments with distinct pricing structures and coverage philosophies. This guide breaks down exactly what each carrier offers, compares real-world costs, and helps you determine which insurer best fits your HVAC business.

Understanding HVAC Contractor Insurance Needs

HVAC contractors face unique risks that require specialized coverage beyond standard business insurance. Your operations involve expensive equipment, skilled labor, property access, and work that directly impacts customer comfort and safety.

Core Coverage Requirements

General Liability Insurance protects your HVAC business when your work causes property damage or bodily injury. A technician accidentally damages a customer's hardwood floor while moving equipment. A homeowner trips over your tools and breaks their wrist. A newly installed HVAC unit leaks and ruins expensive furniture. These scenarios happen more frequently than most contractors expect, making general liability essential.

For HVAC contractors, general liability also covers completed operations claims. If a heating system you installed six months ago malfunctions and causes carbon monoxide exposure, your general liability policy responds to defend your business and cover damages.

Tools and Equipment Coverage addresses one of your largest business investments. Between specialized diagnostic equipment, refrigerant recovery machines, vacuum pumps, and hand tools, most HVAC contractors carry $25,000 to $75,000 in equipment. Get instant quotes from top carriers →

A single van break-in can cost $15,000 to $30,000 in stolen tools and equipment. Inland marine coverage protects your tools whether they're in your shop, in vehicles, or at job sites. This coverage typically includes theft, damage, and loss.

Commercial Auto Insurance covers your service vehicles, which serve as mobile workshops. Standard personal auto policies explicitly exclude business use, leaving you completely unprotected during service calls. Commercial auto provides liability coverage when your employee causes an accident while responding to an emergency call, plus physical damage coverage for your vehicles.

HVAC contractors typically need hired and non-owned auto coverage as well. If an employee uses their personal vehicle for a quick parts run and causes an accident, your business can be held liable. Hired and non-owned auto fills this gap.

Workers Compensation Insurance is legally required in most states once you hire employees. HVAC work involves significant injury risks: falls from roofs and ladders, back injuries from lifting heavy equipment, electrical shocks, heat exhaustion, and refrigerant exposure. Workers compensation covers medical expenses and lost wages when employees are injured on the job, protecting both your workers and your business from costly lawsuits.

Additional Coverage Considerations

Professional Liability/Errors & Omissions protects against claims that your professional advice or services caused financial loss. If you specify the wrong size HVAC system for a commercial building and the client incurs higher energy costs, they might sue for the financial damages. Professional liability covers these claims that fall outside general liability's scope.

Commercial Property Insurance covers your physical location, including your office, shop, and stored inventory. If fire destroys your warehouse containing $100,000 in HVAC units waiting for installation, commercial property insurance replaces that inventory plus building damages.

Umbrella Liability provides additional liability limits above your primary policies. HVAC contractors working on large commercial projects often need $2 million to $5 million in total liability coverage. An umbrella policy provides this extra layer affordably.

Hartford: The Contractor-Focused Carrier

Hartford has built its commercial insurance reputation on serving contractors and tradespeople. Their Hartford Business Owners Policy (BOP) packages general liability and property coverage specifically designed for small to mid-sized HVAC contractors.

Hartford Coverage Strengths for HVAC Contractors

Hartford offers Hired and Non-Owned Auto Coverage automatically included in their general liability policies at no additional cost. This provides crucial protection when employees use personal vehicles for business purposes, a common scenario for HVAC contractors sending technicians for emergency repairs or parts runs.

Their Toolbox Coverage endorsement addresses tools and equipment up to $10,000 as part of their BOP, with options to increase limits substantially. Hartford covers tools both on and off premises, including in vehicles and at job sites. Get instant quotes from top carriers →

Refrigerant Coverage is particularly valuable for HVAC contractors. Hartford's specialized programs understand that refrigerant leaks and environmental claims require specific coverage. Their policies typically include pollution liability for gradual refrigerant leaks, which many standard policies exclude.

Hartford's Equipment Breakdown Coverage protects your own HVAC systems and equipment. If the commercial HVAC system in your office building fails, causing business interruption, this coverage responds. For HVAC contractors, this adds an extra layer of operational protection.

Replacement Cost Coverage for tools and equipment means Hartford pays to replace stolen or damaged equipment with new items rather than depreciated value. If thieves steal your five-year-old manifold gauge set originally worth $800, Hartford pays current replacement cost (potentially $1,100) rather than depreciated value ($400).

Hartford Real-World Costs for HVAC Contractors

Pricing varies significantly based on revenue, employee count, location, and coverage limits, but Hartford generally targets small to mid-sized contractors with competitive pricing.

A one-person HVAC contractor with $150,000 in annual revenue typically pays $1,200 to $1,800 annually for a Hartford BOP including:

$1 million per occurrence general liability
$2 million aggregate
$10,000 tools and equipment coverage
$500,000 in property coverage

A mid-sized HVAC contractor with $750,000 in annual revenue, five employees, and three service vehicles typically pays:

$3,500 to $5,500 for general liability and property (BOP)
$4,200 to $6,800 for workers compensation (varies significantly by state)
$5,400 to $7,200 for three commercial auto policies
Total: $13,100 to $19,500 annually

A larger HVAC contractor with $2 million in revenue, 15 employees, and eight vehicles typically pays:

$8,500 to $12,000 for general liability and property
$18,000 to $28,000 for workers compensation
$14,400 to $19,200 for commercial auto
Total: $40,900 to $59,200 annually

Hartford's pricing becomes particularly competitive for contractors with clean loss histories and established safety programs.

Hartford Claims Handling Example

Consider this real-world Hartford claim scenario: An HVAC technician installs a new air handler in a residential attic. Two weeks later, the homeowner discovers water damage throughout their ceiling and second floor. Investigation reveals the condensate drain line was improperly installed, causing significant water leakage.

The homeowner's damages include:

$18,000 in drywall and ceiling repairs
$6,500 in hardwood floor replacement
$4,200 in temporary hotel costs during repairs
Total damages: $28,700

Hartford assigned a claims adjuster within 24 hours. The adjuster inspected the damage, interviewed the technician, and reviewed installation documentation. Hartford accepted liability, paid for an independent contractor to fix the installation, covered all property damages, and reimbursed hotel costs. Total claim payout: $32,400 including corrective work.

The contractor's premium increased approximately 15% at renewal, but Hartford continued coverage without restricting scope. Get instant quotes from top carriers →

Hartford Limitations

Hartford's specialty contractor programs typically have revenue limits. Contractors exceeding $5 million in annual revenue may need to move to Hartford's excess and surplus lines division or seek coverage elsewhere.

Coverage for highly specialized HVAC work like industrial refrigeration systems, large-scale chiller installations, or healthcare facility HVAC may require additional underwriting or endorsements.

Hartford's digital tools, while improving, lag behind some competitors. Policy management and certificate requests can still require phone calls or emails rather than instant online access.

Chubb: The Premium Protection Option

Chubb targets established HVAC contractors seeking comprehensive coverage with higher limits and broader protection. Chubb typically insures larger contractors, those with significant commercial projects, or businesses requiring complex risk management.

Chubb Coverage Advantages for HVAC Contractors

Chubb's Masterpiece Business program offers significantly broader coverage than standard market policies. Their forms include coverage that other carriers offer only through expensive endorsements or exclude entirely.

Worldwide Coverage extends protection globally rather than limiting coverage to the United States and Canada. For HVAC contractors with international projects or those traveling abroad for specialized installations, this provides seamless protection.

Broad Form Property Coverage eliminates many standard exclusions. Chubb covers property damage from causes that standard policies exclude, providing more comprehensive protection for your tools, equipment, and inventory.

Cyber Liability and Data Breach Coverage increasingly matters for HVAC contractors. Modern HVAC systems connect to building management systems and cloud platforms. If your business experiences a data breach exposing customer information or if ransomware locks your scheduling and billing systems, Chubb's cyber coverage responds.

Higher Automatic Limits distinguish Chubb from Hartford. Where Hartford might include $10,000 in tools coverage as standard, Chubb often provides $25,000 to $50,000 automatically. Medical payments limits, hired auto limits, and supplementary payments all run higher with Chubb.

Blanket Additional Insured Coverage automatically adds your customers as additional insureds without requiring certificate requests or endorsements. Many commercial contracts require this status, and Chubb streamlines the process.

Contractual Liability Coverage is particularly robust with Chubb. Their policies cover your liability assumed under contract with fewer limitations than standard market policies. This matters when signing commercial contracts with hold harmless agreements and indemnification clauses.

Chubb Real-World Costs for HVAC Contractors

Chubb's premium positioning means higher costs, but contractors receive significantly broader coverage. Chubb typically doesn't compete for small contractors under $500,000 in revenue, instead focusing on established businesses.

A mid-sized HVAC contractor with $750,000 in annual revenue typically pays:

$5,200 to $7,800 for general liability and property
$4,500 to $7,200 for workers compensation (comparable to Hartford)
$6,200 to $8,400 for commercial auto
Total: $15,900 to $23,400 annually

This represents approximately 20-30% higher cost than Hartford for significantly broader coverage and higher limits.

A larger HVAC contractor with $2 million in revenue and $5 million in total liability limits (including umbrella) typically pays:

$14,500 to $19,800 for general liability, property, and umbrella
$19,000 to $29,000 for workers compensation
$16,800 to $22,400 for commercial auto
Total: $50,300 to $71,200 annually

For contractors requiring $5 million+ in liability coverage for large commercial projects, Chubb often proves more competitive than Hartford's excess lines markets. Get instant quotes from top carriers →

Chubb Claims Handling Example

Consider this complex Chubb claim: An HVAC contractor installs a commercial rooftop HVAC system for a four-story office building. Six months after installation, the unit's electrical system malfunctions during operation, causing a fire. The fire damages the HVAC unit, the roof, and top floor offices. The building requires evacuation and temporary closure.

Total damages include:

$125,000 in HVAC equipment replacement
$240,000 in building repairs
$180,000 in business interruption for displaced tenants
$45,000 in additional expenses
Total claim: $590,000

Investigation reveals the fire resulted from an electrical connection error during installation. Chubb assigned a dedicated claims team including a technical expert in commercial HVAC systems. They hired forensic engineers, coordinated with the building owner's insurance, and managed complex liability determinations.

Chubb paid the full claim amount within 90 days of completing investigation. They negotiated with the building owner's carrier to minimize subrogation, provided business continuity support to help the contractor maintain operations during the claim, and worked with the contractor's attorney on liability issues.

The contractor's premium increased approximately 25% at renewal, but Chubb maintained coverage without exclusions for electrical work or rooftop installations. Their risk engineering team provided recommendations to prevent future incidents, and Chubb offered credits for implementing suggested safety protocols.

Chubb Limitations

Cost represents Chubb's most significant limitation. Smaller contractors often cannot justify the premium difference, particularly when competing for residential work where comprehensive coverage provides limited competitive advantage.

Chubb's minimum premium requirements effectively exclude contractors under $500,000 in revenue or those with simple risk profiles. Hartford and standard market carriers serve this segment more appropriately.

The underwriting process with Chubb is more intensive, requiring detailed financial information, safety protocols documentation, and sometimes physical inspections. This thorough underwriting ensures appropriate risk assessment but extends the binding timeline.

Choose Hartford If:

You're a smaller contractor with under $1 million in annual revenue. Hartford's competitive pricing and contractor-focused programs make them ideal for businesses establishing themselves in the market.

You need fast binding to meet contract requirements. Hartford's streamlined underwriting means you can secure coverage within days rather than weeks.

You prioritize cost efficiency while maintaining solid coverage. Hartford provides essential protections without premium pricing.

Choose Chubb If:

You're an established contractor with $1 million+ in revenue seeking premium protection. Chubb's broader coverage justifies higher costs for businesses with significant assets to protect.

You handle large commercial projects requiring $5 million+ in liability limits. Chubb's seamless umbrella programs and high limits package better than Hartford's excess lines options.

You face complex contractual requirements with stringent insurance specifications. Chubb's broad form coverage meets most contract requirements without extensive endorsements.

You want superior claims handling with dedicated support teams. For contractors where a large claim could threaten business viability, Chubb's claims reputation provides peace of mind.

You work internationally or on specialized projects requiring coverage beyond standard market offerings.

You've experienced claims with previous carriers and need a market willing to provide comprehensive coverage despite loss history. Chubb often accepts risks that Hartford might restrict or decline.

Cost Optimization Strategies

Regardless of which carrier you choose, several strategies can reduce your HVAC contractor insurance costs:

Implement documented safety programs including regular safety meetings, equipment maintenance schedules, and employee training. Both Hartford and Chubb offer premium credits for documented safety initiatives, typically 5-15% discounts.

Increase deductibles strategically on property and auto physical damage coverage. Raising your deductible from $500 to $2,500 can reduce premiums by 15-25%. Ensure you maintain reserves to cover the higher deductible if needed.

Bundle coverages with a single carrier. Both Hartford and Chubb provide multi-policy discounts when you package general liability, property, auto, and umbrella coverage. Bundling typically saves 10-20% compared to splitting coverage among carriers.

Maintain clean driving records for all employees operating company vehicles. Motor vehicle records directly impact commercial auto pricing. A single DUI can increase your commercial auto premium by 40-60%.

Review your tools and equipment values annually to avoid over-insuring. As equipment ages and you replace or dispose of items, ensure your insured values reflect current inventory. Over-insurance wastes premium dollars.

Consider higher workers compensation deductibles if your cash flow supports it. Large deductible workers compensation programs can reduce premiums by 20-30% for contractors with strong safety records. Get instant quotes from top carriers →

Common HVAC Contractor Insurance Mistakes

Understanding what not to do proves equally valuable as knowing best practices:

Underinsuring tools and equipment leaves you vulnerable to significant out-of-pocket costs after theft or damage. Most contractors underestimate their total equipment value by 30-40%. Conduct a comprehensive inventory annually.

Failing to secure hired and non-owned auto coverage creates exposure when employees use personal vehicles for business purposes. This relatively inexpensive coverage prevents potentially catastrophic gaps.

Neglecting professional liability coverage saves premium dollars today but can cost hundreds of thousands after a specification error or design claim. As HVAC systems become more complex and connected, professional liability claims increase.

Choosing inadequate liability limits to save costs exposes your business and personal assets to judgment creditors. Many contractors carry only $1 million in liability coverage when their actual exposure exceeds $3-5 million.

Ignoring certificate of insurance requirements until contract signing creates delays and lost opportunities. Review insurance requirements early in the bidding process to ensure your coverage meets specifications.

Failing to report claims promptly jeopardizes coverage. Both Hartford and Chubb require "prompt" notice of potential claims. Waiting weeks or months to report an incident can result in claim denial.

Allowing coverage gaps during carrier transitions leaves you completely unprotected. When switching from Hartford to Chubb or vice versa, ensure overlapping effective dates rather than gaps between cancellation and new inception.

Real-World Scenario: Making the Choice

Consider two HVAC contractors facing the Hartford vs Chubb decision:

Contractor A: Residential HVAC Services

$650,000 annual revenue
Four employees
Three service vehicles
Primarily residential installations and service
Some light commercial work
No international exposure

Contractor A chose Hartford and pays approximately $14,200 annually for complete coverage including general liability, property, commercial auto, and workers compensation. The coverage meets all contract requirements for their residential and light commercial work. Hartford's fast binding enables quick responses to new opportunities.

Contractor B: Commercial HVAC Specialist

$3.2 million annual revenue
18 employees
Nine service vehicles
Large commercial projects
Building automation system integration
Occasional international projects
Contract requirements for $5 million liability

Contractor B chose Chubb and pays approximately $58,400 annually. The broader coverage, automatic additional insured status, worldwide protection, and included cyber liability meet their complex contract requirements without constant endorsement requests. Chubb's claims handling provides confidence when managing large projects where a significant claim could threaten business continuity.

Both contractors made appropriate choices for their specific circumstances.

Taking Action

Selecting between Hartford and Chubb for your HVAC contractor insurance requires careful assessment of your business size, project types, coverage needs, and budget. Hartford excels for small to mid-sized contractors prioritizing value and contractor-focused programs. Chubb provides superior breadth and limits for established contractors handling complex commercial work.

Request quotes from both carriers to compare pricing and coverage side-by-side. Provide identical information to each underwriter including revenue, payroll, vehicle details, and loss history. Review the actual policy forms, not just summary declarations, to understand coverage differences.

Work with an independent insurance agent experienced in contractor insurance who can access both Hartford and Chubb markets. Independent agents provide objective guidance and help you understand subtle policy differences that directly impact your protection.

Your HVAC contractor insurance decision affects your business protection for the next year and beyond. Taking time to thoroughly evaluate Hartford and Chubb ensures you secure appropriate coverage at fair pricing, protecting your business, employees, and customers while supporting your growth objectives.

Why Use a Brokerage Platform Instead of Buying Direct?

When a carrier offers instant quote-and-bind on their website, it's convenient — but you're only seeing one carrier's rates. A brokerage platform like Insura changes that equation:

One application, multiple quotes. Fill out one form and get compared across 10+ A-rated carriers including Hartford, Chubb, Hiscox, and more. No need to re-enter your business info on five different websites.
The price is the same — or lower. Carriers pay the broker's commission directly. Your premium is identical to what you'd pay buying direct, and often lower because a broker can find a carrier that prices your specific risk more competitively.
We work for you, not the carrier. A direct carrier's website is designed to sell you their policy. A brokerage platform is designed to find you the best policy — we have no incentive to push one carrier over another.
Automated comparison shopping, year after year. When your policy renews, a brokerage platform automatically re-shops your coverage across carriers to make sure you're still getting the best rate. Buy direct, and you're locked into one carrier's renewal pricing with no leverage.
Licensed experts when you need them. Have a coverage question or need help with a claim? You get access to real brokers — not a carrier's customer service line reading from a script.
