A faulty install doesn't just underperform. It can flood, freeze, or catch fire.
Air conditioning and heating work sits closer to plumbing and electrical risk than most people expect. Refrigerant lines, drainage, and electrical connections all have to be right, and when one isn't, the consequences show up as water damage, a fire, or a system that fails when it's relied on most. Cover sized to match.
Where an HVAC technician actually gets exposed
The exposure here is unusually high for a trade this size, because the failure modes, water, refrigerant, electrical, are all genuinely serious, and most of them only show up after the job's finished.
The install that leaked into the ceiling
A split system you installed has a condensate drain that wasn't fitted correctly. Over several months, water slowly damages the ceiling and the wall below before anyone notices.
The commercial fridge that failed
You service or install refrigeration for a cafe's cool room. A fault in the work causes the unit to fail overnight, spoiling a full stock of perishable food before the business opens the next day.
The refrigerant or gas connection gone wrong
A faulty gas or refrigerant connection during an install leads to a leak. Depending on the system, that can mean anything from an environmental exposure to a genuine fire or explosion risk.
Who's going to ask you for it
Commercial and refrigeration clients check closely
Because failures in this trade can be expensive and sometimes dangerous, clients and licensing bodies both pay attention:
- Head contractors and builders typically want $10M-$20M public liability before engaging HVAC subcontractors.
- Commercial kitchen and cool-room clients often require confirmation of product liability cover specifically.
- Refrigerant handling licensing carries its own compliance obligations alongside insurance.
The exclusion HVAC technicians assume is covered
A leak, a failed condensate drain, or a refrigeration fault found after the job's finished is a defect in the completed installation, not an on-site accident. That's a product liability claim, and it's one of the more serious exposures across all the trades because of how much damage water, refrigerant, or fire can do before it's noticed.
Common questions
A system I installed leaked and damaged a ceiling months later. Is that covered?
Only if product liability is included, not just public liability. Given how much water damage can accumulate before it's noticed, this is worth confirming specifically for this trade.
Does this cover commercial refrigeration and cool rooms?
It can, and it's worth flagging commercial refrigeration work specifically, since a spoiled stock claim can be significant for a hospitality client.
What about refrigerant-related environmental liability?
This is a real exposure in this trade. Tell us about the types of systems and refrigerants you work with so we can confirm the right cover is in place.
Why does this trade carry higher exposure than some other trades?
Because the failure modes, water, refrigerant, electrical, and fire, are all genuinely serious, and a fault often isn't discovered until real damage has already occurred.
I mostly do small residential split-system installs. Do I need the same cover?
The exposure is lower at that scale, but the underlying risks are the same. Tell us the scale and type of work you mostly do so we can size the cover to it.
