You keep Colorado comfortable. We keep your business protected.
Colorado HVAC contractors work in attics, crawl spaces, rooftops, mechanical rooms, and customers' homes every day. You handle gas lines, electrical connections, refrigerants, and heavy equipment, often on tight schedules during brutal winter cold snaps and summer heat waves. One accident, one water leak, or one injured technician can put years of hard work at risk.
At Denver Insurance LLC, we help heating, cooling, and refrigeration contractors put together the right coverage at a competitive price. As an independent agency, we shop multiple carriers so you get a program built around your trade, your crew, and your trucks, not a one-size-fits-all policy.
Why Colorado HVAC Contractors Need Insurance
1. It's often required to get licensed and to work
Colorado doesn't issue a single statewide HVAC license. Mechanical licensing is handled by the city, county, or regional building department where you work, and many of them require proof of insurance. Denver, for example, requires mechanical contractors to show general liability and workers' compensation coverage (or a valid rejection of coverage if you have no employees) before it issues a contractor license. If you work in Denver, Aurora, Colorado Springs, and other towns, you may need to meet a different set of requirements in each one. We'll help you keep up with all of them.
2. Colorado law requires workers' compensation
If you have even one employee in Colorado, full-time, part-time, or family, you're generally required to carry workers' compensation. If you don't, the state can fine you up to $500 for every day you go without coverage, shut down your business until you get insured, and make you pay an injured worker's benefits yourself. HVAC work comes with real injury risks: falls from ladders and roofs, back injuries from lifting heavy units, burns, cuts, and electrical shocks. Workers' comp covers your crew's medical bills and lost wages and helps protect you from lawsuits.
3. General contractors, builders, and property managers won't hire you without it
Commercial jobs, new construction, and property management contracts almost always ask for a certificate of insurance before you start. They often also require additional insured status, a waiver of subrogation, or higher limits. The right policy, with blanket endorsements, makes saying "yes" to those requests quick and easy, so you don't lose the job.
4. Your work keeps going long after you leave the job site
A furnace you installed can malfunction months later. A refrigerant line can leak. A condensate line can back up and ruin a finished basement. A bad venting job can raise carbon monoxide concerns. General liability with products-completed operations coverage protects you against third-party bodily injury and property damage claims from work you've already finished.
5. Your trucks are your rolling shop
Your personal auto policy may not cover vehicles used for business. Colorado's minimum auto liability limits are 25/50/15 ($25,000 per person and $50,000 per accident for bodily injury, plus $15,000 for property damage), and those minimums run out fast after a serious accident. If someone sues for more than your limits, the business can be on the hook for the rest. Commercial auto, plus hired and non-owned auto coverage, protects your vans, your drivers, and your business.
6. Your tools and equipment are expensive and they move
Recovery machines, vacuum pumps, manifold gauges, combustion analyzers, and power tools get stolen from trucks and job sites all the time. Contractor's equipment and tools coverage (inland marine) protects your gear wherever it is. An installation floater covers equipment and materials while they're in transit or waiting to be installed, before the customer takes ownership.
7. One big claim can go past your limits
A serious injury or a fire tied to a gas appliance can lead to a claim larger than your primary policy limits. An umbrella or excess liability policy adds an extra layer of protection, and many larger commercial contracts require one.
8. Today's risks go beyond the job site
Many HVAC businesses take card payments, store customer data, and run on scheduling software, so cyber liability is worth a look. If you have employees, employment practices liability (EPL) protects you against claims of wrongful termination, discrimination, and harassment. Many jobs also require license, permit, or contract surety bonds.

FAQ: Questions HVAC Contractors Ask About Insurance
Do I need insurance to get an HVAC license in Colorado?
Colorado doesn't have one statewide HVAC license. Licensing is handled locally, and many jurisdictions require proof of insurance. Denver, for example, requires general liability and workers' compensation (or a valid rejection of coverage) for its contractor licenses. Since requirements differ by city and county, check with every jurisdiction where you work. We can help you put together the certificates each one needs.
I'm a one-person shop. Do I need workers' comp?
Colorado generally requires workers' compensation once you have one or more employees. Some business owners with no employees can formally reject coverage, but that rejection doesn't cover anyone you hire later, even part-time help or family. Also keep in mind that if you're injured without coverage, your health insurance may not cover a work injury. We'll go through your options with you.
Can I just call my helpers independent contractors?
Be careful. In Colorado, a person paid to perform services is presumed to be an employee, and calling someone a "1099 contractor" doesn't change that by itself. If a subcontractor doesn't carry their own workers' comp, their payroll can be added to your policy at audit, and you could owe more premium. Always get a current certificate of insurance from every sub.
What's the difference between general liability and workers' comp?
General liability covers injuries to other people and damage to their property, like a customer who trips over your hose or a ceiling damaged by a leak. Workers' comp covers injuries to your own employees.
What is "products-completed operations" coverage, and why does it matter for HVAC?
It covers claims from work you've already finished, like a system that malfunctions, leaks, or causes a fire weeks or months after installation. For HVAC contractors, this is one of the most important parts of a general liability policy.
Does my personal auto policy cover my work van?
Often it doesn't, especially if the vehicle is titled to the business, carries tools and equipment, or is driven by employees. Commercial auto is designed for business use. If your employees run errands in their own cars, hired and non-owned auto coverage fills that gap.
Are my tools covered if they're stolen from my truck?
Usually not under a general liability or auto policy. Contractor's equipment or tools coverage (inland marine) is the right protection for tools and equipment that travel with you.
What is an installation floater?
It covers HVAC equipment and materials, like condensers, furnaces, and ductwork, while they're in transit, stored on site, or being installed, until the job is complete and accepted.
A general contractor wants me to add them as an "additional insured" and provide a "waiver of subrogation." What does that mean?
Additional insured status extends your liability coverage to the GC for claims arising from your work. A waiver of subrogation means your insurer won't try to recover a claim payment from the GC. Many contractor policies include blanket versions of both, so you don't need a separate endorsement for every job.
How much general liability coverage do I need?
Many contracts and local licensing requirements use $1,000,000 per occurrence / $2,000,000 aggregate as a baseline. Larger commercial jobs may require more, which is where an umbrella policy comes in. Check your contracts and we'll recommend the right limits.
Do I need an umbrella policy?
If you do commercial work, run several trucks, or sign contracts with high limit requirements, an umbrella is an affordable way to add protection above your GL, auto, and employer's liability policies.
Does it matter if I do rooftop units, boilers, or propane work?
Yes. Carriers look closely at rooftop work, commercial boiler installation, solid-fuel appliances, and LPG/propane work, and these can affect which carriers will write you and what you'll pay. Tell us about all of your operations up front so the policy is set up correctly and there are no surprises at claim time.
Why does my premium change after an audit?
General liability and workers' comp are often priced on estimated payroll or revenue. At the end of the policy term, the carrier audits your actual numbers. If you grew, hired, or used uninsured subcontractors, the premium may go up. Giving accurate estimates up front helps you avoid a big audit bill.
Can I bundle my coverage?
Often, yes. Depending on your size and operations, some HVAC contractors qualify for a business owner's policy (BOP) or contractor package that combines liability, property, and tools coverage, and many carriers offer multi-policy discounts with commercial auto.
Do I need a bond as well as insurance?
Possibly. Many cities, counties, and project owners require license, permit, or contract surety bonds. A bond guarantees your obligations to the customer or the jurisdiction. It isn't insurance for your business, but we can help you get one.
How fast can I get a certificate of insurance?
Once your policy is in force, we can usually turn around routine certificate requests quickly, so you can start the job without delays.
What information do you need to quote my HVAC business?
Usually: years in business, your type of work (residential or commercial, service or new construction), annual revenue, payroll, number of employees, subcontractor costs, vehicles and drivers, tools and equipment values, current policies, and loss history.
