What a Home Warranty Does Not Cover

A home warranty can take the sting out of a broken furnace or a dead dishwasher. But many frustrations with home warranties come from not knowing what the plan leaves out. Understanding the common exclusions before you buy helps you pick the right plan and avoid surprises when you file a claim.

Pre-existing conditions

Most home warranties exclude problems that existed before coverage started. If your water heater was already leaking or your AC was already struggling when you bought the plan, a claim for that issue may be denied.

Some plans cover pre-existing conditions that were unknown and could not have been detected by a simple visual or mechanical check. Read how the contract defines this, since it varies from plan to plan.

Lack of maintenance

Home warranties cover breakdowns from normal use, not damage caused by neglect. Common examples of maintenance-related denials include:

• An HVAC system that failed after years without filter changes
• A water heater damaged by heavy sediment buildup
• A clogged dryer vent that caused overheating

Keep receipts for service visits and note routine tasks like filter changes. Records help if a claim is questioned. A simple notebook or a folder on your phone with dates and photos is often enough. If you hire a professional for a tune-up, ask for an itemized invoice that lists what was checked.

Code violations and upgrades

If a repair requires bringing equipment up to current building codes, many plans will not pay for those extra costs, or they cap them. The same applies to permits, removal of old equipment, and modifications needed to fit a new unit. Some plans include a limited allowance for these costs.

This often comes up with older HVAC systems and water heaters, where a replacement unit may not fit the existing setup without changes.

Structural parts and secondary damage

Home warranties focus on systems and appliances. They generally do not cover:

• Foundations, walls, floors, and ceilings
• Windows and doors
• Driveways, walkways, and patios
• Most cosmetic issues

Roofs are a special case. A few plans offer limited roof leak coverage as an add-on, but full roof replacement is typically excluded.

If a covered pipe bursts, the plan may pay to fix the pipe but not the damaged drywall, flooring, or belongings. That kind of damage generally falls under homeowners insurance, subject to your policy. A home warranty and homeowners insurance are separate products that cover different things. Many homeowners carry both, using insurance for sudden damage and the warranty for worn-out systems and appliances.

Items that are often excluded or optional

Many plans exclude or charge extra for:

• Pools and spas
• Well pumps and septic systems
• Second refrigerators and standalone freezers
• Sump pumps
• Outdoor plumbing and sprinkler systems
• Solar panels and generators
• Smart home devices and security systems

If any of these matter to you, check whether the plan offers them as add-ons.

Coverage limits and caps

Even covered items have limits. Contracts often set a maximum dollar amount per repair, per item, or per year. Some systems, like HVAC, may have their own cap. If a repair exceeds the cap, you pay the difference.

Also look for limits on:

• Specific parts, like compressors or heat exchangers
• Refrigerant recovery and recharging
• Access costs, such as cutting into walls or concrete to reach a pipe

How to spot exclusions before you buy

1. Read the sample contract, not just the brochure
2. Find the exclusions section and read every line
3. Check the coverage limits for each system and appliance
4. Look at the definitions of "pre-existing condition" and "normal wear"
5. Ask about add-ons for items you care about
6. Confirm the service fee per visit
