Does insurance cover a failed furnace or air conditioner?

A homeowners policy almost never pays to replace a furnace or an air conditioner that simply stopped working. Mechanical failure and wear are excluded in nearly every policy. What it does cover is damage the failure caused, and damage to the unit from a covered peril such as fire, lightning, or a falling tree.

For the equipment itself, the products are an equipment breakdown endorsement or a home warranty, and they are not the same thing.

The line the policy draws

Covered:

• Fire damage to the system, or fire caused by it.
• Lightning damage.
• A tree or storm debris destroying an outdoor unit. Storm damage generally.
• Theft of an outdoor unit, which is a real and common claim.
• Water damage caused by the system, such as a condensate overflow flooding a ceiling, where it was sudden rather than a long term drip.
• Burst pipes caused by the heating failing in a freeze, in most policies, provided the property was occupied and heated or properly drained. Which is the condition people trip over.

Not covered:

• The compressor failing.
• The heat exchanger cracking.
• A blower motor or a control board burning out.
• Refrigerant leaks.
• Anything described as wear, age, rust, or lack of maintenance.
• Damage from a repair that was never done.

The principle is the same one that governs water and electrical claims: the policy pays for damage, not for the part that failed.

Equipment breakdown coverage

An endorsement, sold by many insurers for a modest annual amount, that covers sudden mechanical or electrical breakdown of home systems and appliances. It typically includes heating and cooling equipment, water heaters, and major appliances, with its own deductible and its own limit.

What it usually does cover: a compressor that fails, a control board that burns out, a motor that seizes, and often the resulting spoilage or damage.

What it usually does not: wear and gradual deterioration, maintenance, and anything already failing when the endorsement was bought.

It is one of the better value endorsements available if a house has aging mechanical equipment. Ask what it costs at renewal.

Home warranties, which are a different product

A home warranty is a service contract, not insurance. You pay an annual fee plus a service call fee per visit, and the company sends a contractor from its own network.

The realistic picture:

• They do cover mechanical failure, which is exactly what homeowners insurance excludes.
• They cap payouts per item, often well below the cost of replacing a system.
• They exclude pre-existing conditions and poor maintenance, and that exclusion is where most disputes happen.
• You usually cannot choose the contractor, and in a cold snap you are in their queue rather than one you control.
• They frequently repair rather than replace, and repeatedly.

Whether one is worth it depends on the age of the equipment and how much you mind the loss of control. Read the cap and the exclusions before the marketing.

The freeze exclusion, which catches people

Most policies exclude damage from frozen plumbing where the property was unoccupied and the heat was not maintained, or the system not drained. That matters here because a failed furnace in an empty house is exactly that scenario.

If you are away and the heating fails, the policy generally expects that you had taken reasonable precautions: heat maintained, or water shut off and the system drained, or someone checking the property. Smart thermostats with low temperature alerts and cheap network connected temperature sensors both make that defensible, and both cost less than one claim.

Claiming when the failure caused damage

1. Stop the damage first. Water off, power off, whatever applies.
2. Photograph everything, including the failed unit and any water.
3. Report promptly.
4. Get a written cause from the technician, saying what failed and whether it was sudden. This is the document the claim turns on.
5. Keep the failed part if it is small enough.
6. Keep the service records. A maintained system defeats the neglect argument before it starts.

Landlord and tenant

Heating is a landlord repair obligation nearly everywhere, and in freezing conditions it is usually an emergency one with a statutory response time. A tenant’s own contents policy covers their belongings, not the boiler. The wider split.

Before it happens

• Ask what equipment breakdown coverage costs at renewal.
• Keep annual service records for every fuel burning appliance.
• Fit a low temperature alert if the house is ever empty in winter.
• Know the age of the system. Past a certain point, replacement planning beats repair budgeting. What the work actually costs.

The short version

The unit failing is not an insured event; the damage it causes usually is. Equipment breakdown coverage is the endorsement that covers the equipment, and a home warranty is a capped service contract rather than insurance. Keep service records, and if the house will be empty in a freeze, either maintain the heat or drain the system.
