Cost
Most solo HVAC contractors pay between $650 and $2,000 a year for general liability. Here's what drives the number — and what you'd likely pay.
HVAC insurance costs more than lighter trades because of what's actually at stake — combustion, gas lines, and refrigerant. Here are typical ranges for the most common coverage types:
Carriers rate HVAC higher than trades like painting or landscaping for one central reason: combustion and carbon monoxide exposure. Improper venting or a bad gas line connection isn't a cosmetic mistake — it's a life-safety claim. Add refrigerant handling and EPA Section 608 requirements on top of that, and HVAC lands in a premium band closer to electrical work than to general handyman services.
Insurance carriers rate HVAC businesses based on several key factors. Understanding these helps you know what to expect when you request a quote.
This is the single biggest driver of your GL premium. An HVAC contractor doing $75,000 a year in revenue pays significantly less than one doing $400,000. Carriers use revenue as a proxy for exposure — more jobs means more potential for claims.
New installation work often carries different exposure than service and repair calls. A full system install touches gas lines, electrical connections, and combustion appliances from the ground up, while a service call may be narrower in scope. Carriers want to know your mix so they can rate it accurately — and it affects your completed operations exposure too.
Any work involving furnaces, boilers, or other combustion appliances carries carbon monoxide exposure. This is the single biggest severity driver in HVAC underwriting — a claim here isn't a cracked window, it's a bodily injury claim with real limits attached.
If you handle refrigerant, carriers will ask about your EPA Section 608 certification. Certified technicians working within EPA guidelines are viewed more favorably than uncertified handling, which can affect both eligibility and rate.
Adding employees increases your premium because it increases your exposure. Subcontractors can also affect your rate depending on how much of your revenue they represent. If you use subs, your policy needs to account for that exposure.
If you add inland marine (tools and equipment) coverage, the premium is based on the total value of your gear — manifold gauges, refrigerant recovery machines, combustion analyzers, and leak detectors. More valuable equipment means higher premium.
HVAC revenue often swings between heating season and cooling season. Carriers factor this into how they view your annual revenue reporting — a business that's slow in spring but slammed in July and January isn't unusual, and a good quote accounts for that instead of penalizing it.
Most HVAC contractors start with $1M per occurrence / $2M aggregate. Some commercial mechanical clients and GCs require $2M/$4M, which costs more but is often a job requirement.
Insurance rates vary by state due to different regulatory environments, claim histories, and market competition. Some states are simply more expensive to insure HVAC work in than others.
Annual policies cover all your work for the year and are almost always more cost-effective than per-job coverage. They also make producing certificates of insurance easy — one policy covers every client and GC you work with all year. We focus on annual policies for exactly this reason.
The best way to know your exact premium is to request a quote. Our licensed agents will ask about your revenue, your install-vs-service mix, your combustion and refrigerant exposure, your employees and subcontractors, and your equipment — then shop multiple carriers to find the best fit for your operation.

FAQ
Most solo HVAC contractors with no employees pay between $650 and $1,400 a year for general liability. Adding equipment coverage typically brings the total to $900–$2,200 depending on your equipment value.
Carbon monoxide and combustion exposure from furnace and boiler work, plus refrigerant handling requirements, put HVAC in a higher severity band than trades without gas or combustion exposure.
It can. Full installations touch gas lines, electrical connections, and combustion appliances from the ground up, and often carry more completed operations exposure than a narrower service call.
Carriers understand that HVAC revenue swings between heating and cooling season. Tell us your seasonal mix so we can match you with a carrier that rates it fairly instead of penalizing the swing.
Most HVAC contractors start with $1M per occurrence / $2M aggregate, which satisfies the requirements of most residential clients and GCs. Some commercial mechanical projects require $2M/$4M. We can quote both.
