Risk
Skipping insurance doesn't make combustion work safer — it just changes who's on the hook, and in this trade, that exposure carries a higher ceiling than most.
A bad venting job produces the same carbon monoxide exposure whether you're insured or not. Skipping coverage doesn't change what could go wrong on the next job — it only determines who's left paying for it, and for an uninsured HVAC contractor, that's not a carrier, it's you personally.
Municipal permitting offices increasingly require proof of insurance as part of a mechanical or gas permit application, and commercial GCs won't mobilize a mechanical sub without a certificate on file. Show up without one and you're not just missing a permit — you're locked out of the job entirely before your crew ever shows up.
Plenty of HVAC business owners assume their LLC creates a hard wall between a claim and their personal assets. That wall has real limits, especially for smaller operations where business and personal finances blend together — and an uninsured claim is exactly the scenario where a plaintiff's attorney has the most reason to test those limits, since there's no policy standing in the way.
A carbon monoxide incident isn't a property damage claim — it's a bodily injury claim, sometimes a fatality claim, and the severity ceiling reflects that. General liability exists in this trade precisely because combustion and refrigerant work carry a genuinely higher worst-case outcome than most other artisan contractor trades, and an uninsured claim in this space can be financially catastrophic in a way a lighter trade's claim rarely is.
A claim that's ultimately found meritless still requires a legal defense from the first letter to the final resolution, and that cost doesn't disappear because you were in the right. Without a policy funding it, an uninsured contractor pays that bill personally either way.
Nobody skips coverage after actually weighing the odds — it's almost always a lapsed renewal or a "get to it after the season" that never happened. A quote takes a few minutes and turns an abstract risk into a real number. See our cost breakdown for where that number typically lands.

FAQ
Yes — many jurisdictions require proof of insurance as part of the mechanical or gas permit application, separate from anything a GC or client requests.
Not always. Courts can disregard the LLC structure in certain circumstances, particularly for smaller operations where business and personal finances aren't kept genuinely separate.
CO exposure is a bodily injury issue, sometimes life-threatening, which carries a fundamentally higher severity ceiling than property damage — that's why adequate GL limits matter more in this trade than in most.
Yes — legal defense costs accrue throughout the dispute regardless of outcome, and without a policy funding that defense, those costs come out of your own pocket even if you're ultimately found not liable.
A clean history doesn't reduce the exposure sitting on your next job — it just means the claim hasn't happened yet. Given the severity ceiling in this trade, that's a bigger bet than most contractors realize they're making.
