HVAC Insurance Cost & Coverage Guide

Q: If I am installing a new AC unit and accidentally cause water damage to the client's ceiling, is that covered by general liability?

Yes. General liability insurance is designed to cover accidental property damage to a third party. The cost to repair the water-damaged ceiling would typically be covered under your policy, up to its limits.

Q: Are my expensive refrigerant recovery machines and other tools covered if they are stolen from the job site?

Yes, if you have Contractor's Tools and Equipment insurance (also known as inland marine insurance). This policy specifically protects your gear from theft and damage while it's away from your primary business location.

Q: If one of my technicians suffers an injury while working, which insurance policy covers their lost wages and medical bills?

Their lost wages and medical bills would be covered by your Workers' Compensation insurance. This policy is required in most states for businesses with employees and is essential for protecting your team and your business.

Q: Does my insurance premium depend on whether I work on residential systems versus large commercial ones?

Yes, it often does. Working on large, complex commercial HVAC systems is typically considered higher risk than standard residential work. This increased risk is usually reflected in a higher insurance premium.

Q: Is it required by law?

Whether you need coverage depends on the state where you work, and if you have employees. But even if it’s not required, we recommend getting insured to protect your business financially. And in some instances, clients or landlords may require you to have that before they’ll work with you.

Q: A client is claiming my work caused an electrical issue that damaged their appliances. Does my general liability policy help cover that?

Yes. If your work is found to have directly caused an electrical surge or fault that damaged the client's property (their appliances), your general liability policy would typically cover the cost to repair or replace them.

HVAC Insurance Cost

As an HVAC contractor, you’re an expert at keeping things running smoothly. But on any job site, things can go wrong. An accidental water leak during an AC install, a stolen refrigerant recovery machine, or an employee injury can lead to thousands of dollars in unexpected costs. That’s where HVAC contractor insurance comes in—it’s your financial safety net, protecting your business so one mishap doesn’t freeze your finances.

This guide will break down how much HVAC insurance can cost, what affects the price, and how we make getting coverage easier and more affordable.

HVAC Contractor Insurance

Your work involves complex systems, expensive tools, and working in clients’ homes and businesses. This exposes you to unique risks every day. HVAC contractor insurance is a suite of policies designed to protect your business from the financial consequences of accidents, property damage, employee injuries, and lawsuits. Without the right coverage, you could be personally responsible for paying for costly legal fees, medical bills, and equipment replacement.

How Much Does HVAC Insurance Coverage Cost?

The cost of HVAC business insurance varies, but most pay a median price of $68 per month, or about $821 per year, for a policy package. Your final premium depends on factors like your location, number of employees, the type of work you do (residential vs. commercial), and your claims history.

Here’s a look at the median costs¹ for the most common policies HVAC businesses purchase.

Insurance Policy	Median Monthly Cost	Median Annual Cost
General Liability	$55	$662
Workers’ Compensation	$127	$1,524
Tools & Equipment	$25	$295

Reflected price tiers may not include purchase of all available policies under HVAC insurance.

What Insurance Does an HVAC Business Need?

While every business is unique, most HVAC contractors need a combination of the following coverages to be fully protected from common on-the-job risks.

General liability

This is the foundation of your protection. It covers costs related to third-party accidents, property damage, and bodily injury claims that happen as a result of your work.

Why You Need It: While installing a new AC unit in an attic, a drain line isn’t properly secured, leading to a slow leak that causes significant water damage to the client’s ceiling. Your general liability policy can cover the cost to repair the ceiling and any other water damage.

Median Cost: $55/month

Contractor’s tools & equipment (Inland marine)

Your specialized tools—from refrigerant recovery machines to vacuum pumps—are expensive and essential. This policy protects your gear from theft or damage, whether it’s at a job site, in your work van, or in storage.

Why You Need It: Your work truck is broken into overnight and your multimeters, recovery machines, and other valuable tools are stolen. This coverage can help pay to replace them, minimizing your downtime and financial loss.

Median Cost: $25/month

Workers’ comp

If you have employees—even just one part-timer—most states require you to carry workers’ compensation. This policy covers medical bills and lost wages for employees who get injured or become ill on the job.

Why You Need It: One of your technicians suffers a severe back strain while lifting a heavy furnace into place. Workers’ comp can cover their hospital bills, physical therapy, and a portion of their lost wages while they recover.

Median Cost: $127/month
