Here's a claim we see owners discover they don't have — the hard way. A warehouse in Texas runs a dozen rooftop HVAC units through a brutal August. A compressor seizes. The repair bill is $38,000, plus three weeks where the building can't hold temperature and the tenant withholds rent. The owner files a property claim. The carrier denies it in one paragraph: mechanical breakdown is excluded. The fire that burns the building down? Covered. The equipment that quietly dies and takes the business with it? Not covered.
That gap has a name, and closing it costs a fraction of what owners assume. Equipment breakdown insurance — the modern successor to what used to be called boiler and machinery coverage — pays for the mechanical and electrical failures that a standard commercial property policy specifically excludes. It's one of the most underpriced, most frequently skipped coverages in commercial insurance, and it's the one that saves an owner's year when a single critical system fails.
The Exclusion Hiding in Your Property Policy
Most owners read their commercial property policy as "if the building is damaged, I'm covered." That's mostly true — for outside causes. Fire, wind, hail, water, theft, vandalism: those are covered perils, and the property policy responds. But every standard form, from ISO's Building and Personal Property form on up, carries an exclusion for internal failures: mechanical breakdown, electrical arcing, short circuits, artificially generated electrical current, and the wear-and-tear that ends a machine's life.
Think of it as two insurance questions with two different answers:
- Did something outside damage your equipment? A fire, a storm, a water line break — property insurance pays.
- Did the equipment damage itself? A motor that burns out, a compressor that seizes, a boiler that cracks from pressure — property insurance says no. That's an equipment breakdown loss.
The line matters because equipment failures are far more common than fires. Statistically, a commercial building is orders of magnitude more likely to lose an HVAC unit or an electrical panel than to burn down. Yet owners carry hundreds of thousands in fire coverage and nothing for the failure that actually happens.
When a carrier denies an equipment claim for "mechanical breakdown," they're not being difficult — they're applying a near-universal exclusion. The fix isn't to argue; it's to carry the equipment breakdown endorsement that exists specifically to respond to what the property form excludes. Without it, no amount of property limit will cover a seized compressor.
What Equipment Breakdown Coverage Actually Pays For
Equipment breakdown insurance pays to repair or replace equipment that fails from internal causes. The covered causes of loss are mechanical breakdown, electrical arcing, short circuits, and artificially generated electrical current (a surge originating inside your own system — not a lightning strike, which the property policy already covers). Here's what that maps to in a real building:
| Equipment | Typical Failure | Covered By |
|---|---|---|
| HVAC / chillers | Compressor seizure, motor burnout, refrigerant leak | Equipment breakdown |
| Electrical panels & switchgear | Arcing, short circuit, internal surge damage | Equipment breakdown |
| Boilers & pressure vessels | Internal cracking, pressure failure | Equipment breakdown |
| Refrigeration & coolers | Compressor or condenser failure | Equipment breakdown |
| Elevators & lifts | Motor or control failure | Equipment breakdown |
| Production machinery | Motor burnout, bearing failure | Equipment breakdown |
Critically, equipment breakdown coverage doesn't just pay for the broken part. Most policies extend to three follow-on losses, which is where the real money hides:
- Resulting property damage. If an arcing panel starts a fire or a failed boiler floods a room, the damage that failure caused is covered.
- Spoilage. A failed walk-in cooler can destroy tens of thousands in perishable inventory. Spoilage coverage responds to that.
- Business income / rental loss. If the breakdown shuts you down or forces a tenant out, the lost income during restoration is covered — often the largest part of the claim.

What It Costs — And Why It's the Best Value in Your Policy
Equipment breakdown is cheap because it's high-frequency, low-severity relative to catastrophe risk. A carrier doesn't face a $50 million earthquake exposure on an equipment endorsement — it faces a $40,000 compressor here and a $20,000 panel there, which it can price with confidence. That math works in your favor:
| Property Type | Typical Annual Cost | What It Protects |
|---|---|---|
| Apartment building | $250 – $750 | Central HVAC, boilers, elevators, domestic water heaters |
| Strip mall / retail | $300 – $800 | Rooftop HVAC, shared electrical, walk-in coolers |
| Warehouse | $500 – $1,500 | HVAC, refrigeration, dock equipment, racking electrical |
| Hotel | $1,000 – $3,000 | Boilers, chillers, commercial kitchens, laundry, elevators |
| Gas station | $500 – $1,200 | Fuel pumps, dispensers, tank monitoring, coolers |
Set those premiums against the losses. A single failed chiller on a hotel in an Illinois winter can run $60,000 to replace and thousands more in lost room revenue while it's down. A supermarket-grade refrigeration failure can spoil $50,000 in inventory in a weekend. On a pure expected-value basis, equipment breakdown coverage is routinely the cheapest meaningful protection you can add to a commercial policy.
If your building has any one system that would stop operations or displace tenants if it failed — and nearly every commercial building does — equipment breakdown is not optional coverage. It's the gap between "insured against fires I'll never have" and "insured against the failure I'll probably have."
Who Needs It: Property Type by Property Type
Every property type in our book has a real equipment breakdown exposure. Here's what the risk actually looks like in each:
Warehouses & Industrial
Warehouses are the classic skip. Owners see a big steel box and assume there's no equipment to break — then a refrigeration unit fails and destroys a cold-storage tenant's entire inventory, or a dock-leveler motor seizes and halts shipping for a week. For a deeper look at the full industrial program, see our warehouse insurance guide and our 2026 warehouse insurance overview.
Apartments & Multifamily
A central boiler or a single elevator serving a 40-unit building is a concentration point. If it fails in a California winter or a Texas heat wave, you've got tenants calling, code pressure, and a bill no property policy will touch. See our apartment building insurance page.
Hotels & Hospitality
Hotels carry the densest equipment exposure of any property type — boilers, chillers, commercial kitchens, laundry, elevators, and pool systems all in one building. A failed chiller doesn't just cost the part; it costs the guests who check out early. See our hotel insurance page.
Gas Stations & C-Stores
Fuel pumps and dispensers are expensive, precision equipment, and a failed pump is a dead island of revenue until it's replaced. Coolers and tank-monitoring systems add more exposure. See our gas station insurance page.
Strip Malls & Retail
Rooftop HVAC units, shared electrical infrastructure, and tenant walk-in coolers concentrate risk. When one unit fails, the lease dispute over who pays usually follows. See our strip mall insurance page.
State-by-State: What Drives Equipment Loss in CA, TX & IL
Equipment breakdown risk isn't uniform across our three markets. Climate and building stock change what breaks first:
California — HVAC Load & Aging Electrical
California's inland heat and coastal salt air push HVAC systems hard, and the state's aging commercial stock means a lot of panels and switchgear are decades past their design life. Combine an old panel with a heat wave and you get exactly the arcing and short-circuit losses equipment breakdown coverage is built for. See our California apartment insurance page.
Texas — Heat, Storms & Power Surges
Texas summers run compressors to failure, and the state's storm patterns bring voltage fluctuation that stresses every motor and panel in a building. A freeze-and-thaw cycle is brutal on boilers and water lines. See our Texas storm coverage guide and our Texas apartment insurance page.
Illinois — Boilers, Freeze & Old Masonry Stock
Illinois's winter makes the boiler the single most critical piece of equipment in any building — and the most likely to fail at the worst possible moment. A January boiler failure in a Chicago apartment building isn't just a repair; it's an emergency with freeze damage, tenant displacement, and habitability claims. See our Illinois commercial building guide.
How to Buy It the Right Way
Equipment breakdown coverage is almost always added as an endorsement or a standalone policy alongside your property coverage. The key decisions are the limit, the deductible, and the equipment schedule:
What to Get Right on an Equipment Breakdown Endorsement
- Set a realistic limit. Base it on your single most expensive piece of equipment plus a realistic business-income figure — not a token number. A $50,000 limit won't cover a $60,000 chiller plus lost revenue.
- Include business income / rental value. This is the follow-on coverage that turns a part replacement into a survivable event. Skip it and you're covering the equipment but not the shutdown.
- List your equipment accurately. Underwriters price on the schedule. Omit the walk-in cooler or the elevator and you've bought coverage for the building but not the equipment that matters.
- Confirm spoilage sub-limits. If you hold perishable inventory — a gas station's coolers, a warehouse's cold storage — make sure spoilage is included and adequate.
- Ask about service-contract coordination. Some policies reduce what they pay if the equipment was under a manufacturer warranty or maintenance contract. Know the overlap before you rely on it.

Frequently Asked Questions
Does commercial property insurance cover equipment breakdown? No — property insurance excludes mechanical breakdown, electrical arcing, and other internal failures. Equipment breakdown coverage exists specifically to fill that exclusion.
How much does equipment breakdown insurance cost? Typically $250 to $3,000 per year depending on the property type and equipment schedule — a fraction of a single major equipment replacement or a shutdown's lost income.
What does equipment breakdown insurance cover? Repair or replacement of equipment that fails from internal causes — HVAC, electrical panels, boilers, refrigeration, elevators, and machinery — plus resulting property damage, spoilage, and business income loss.
What's the difference between equipment breakdown and property insurance? Property insurance responds to outside causes (fire, storm, water, theft); equipment breakdown responds to inside causes (motor burnout, compressor seizure, arcing, boiler cracks). They're complementary, not overlapping.
Who needs equipment breakdown insurance? Any owner whose building depends on mechanical or electrical systems — warehouses, apartments, hotels, gas stations, and strip malls all carry real exposure. If one system failing would stop operations, you need it.
You wouldn't operate a building without fire coverage, and you probably never will — but you'll likely replace an HVAC unit or electrical panel long before you ever file a fire claim. Equipment breakdown coverage is the rare insurance that protects against the loss you'll actually have, for a cost measured in the hundreds, not the thousands. If a single mechanical failure could stop your building, this is the coverage that keeps that failure from becoming your problem.
