Does commercial property insurance cover equipment that breaks down on its own?

All FAQs

Quick answer: No. The mechanical or electrical failure of equipment such as HVAC units, boilers, or refrigeration is a standard exclusion. That loss is covered by a separate equipment breakdown endorsement, not the base commercial property form. Physical damage from a covered peril like fire or storm is still covered by the property policy.

A commercial property policy does not cover equipment that fails on its own, without any outside physical damage. Mechanical breakdown and electrical failure of items like HVAC units, boilers, refrigeration systems, and other equipment are standard exclusions on the base commercial property form, regardless of carrier. That gap exists because a standard property policy is built to respond to sudden external perils, such as fire, windstorm, theft, and vandalism, not to the internal wear, electrical short, or mechanical failure of a piece of equipment operating as designed until it stops.

Equipment breakdown coverage fills that specific gap. It is typically added to a commercial property policy as an endorsement, an add-on provision that expands or modifies what the base policy covers, rather than sold as a fully separate policy. Equipment breakdown coverage responds to losses like a motor burning out, a boiler rupturing under normal operating pressure, or a refrigeration compressor failing electrically, along with the spoilage or business interruption those failures cause.

The distinction matters in a real claim. For example, if lightning strikes a building and damages a rooftop HVAC unit, that is physical damage from a covered external peril, and the base commercial property policy responds. If the same HVAC unit's compressor simply burns out from an internal electrical fault during normal operation, with no external cause, that loss falls to equipment breakdown coverage instead, and a policy without that endorsement leaves the repair or replacement cost uncovered.

Businesses that depend on refrigeration, climate control, or production equipment, such as restaurants, grocery stores, medical offices, and light manufacturers, carry more of this exposure than an office-based business with minimal mechanical equipment. A coverage review can identify which pieces of equipment on a property represent the largest breakdown exposure and confirm whether an endorsement or a separate policy fits the property's existing program.
