OneGuard Home Warranty: Plans, Pricing and Claims

When your air conditioner quits during a Texas heatwave or your water heater floods the garage, a single repair can cost thousands. A one guard home warranty covers the repair or replacement of major home systems and appliances when they break down from normal wear and tear. This guide covers the real plan details, pricing, coverage limits, and the claim process.

Quick Answer: One Guard Home Warranty at a Glance

OneGuard Home Warranties sells three tiered plans — Sentinel, Centurion, and Guardian — priced annually: a buyer’s 1-year plan runs $399, $499, or $599 depending on tier and state, and the 4-year new construction plan runs $649, $799, or $949. Every service visit carries a $69–$75 service call fee (per the official brochures). Coverage includes repair or replacement of covered systems and appliances, plus unusual benefits like unknown pre-existing conditions.

One Guard Home Warranty Plans in Detail

Sentinel is the entry plan, covering core home systems: air conditioning and heating, ductwork, electrical, plumbing, water heater, dishwasher, garbage disposal, range/oven/cooktop, built-in microwave, ceiling and exhaust fans, central vacuum, and garage door openers. It also bundles maintenance-style services like a mechanical inspection, re-key service, and garage remote re-programming.

Centurion upgrades Sentinel with the Preferred Upgrade and HVAC Equipment Incompatibility Protection — coverage that pays when your HVAC equipment doesn’t match properly and causes a failure. Centurion also adds extra service items, making it the middle tier for homes with aging HVAC equipment.

Guardian is the top tier: everything in Centurion plus extended main line plumbing, a washer/dryer set, and the kitchen refrigerator. If your laundry appliances or fridge are older, Guardian closes the biggest coverage gaps in the lower plans.

What Does the One Guard Home Warranty Cover?

Like all home warranties, OneGuard covers repair or replacement when covered items break from normal wear and tear. Where OneGuard stands out is the fine print most companies exclude: unknown pre-existing conditions (problems undetectable by a visual inspection and simple mechanical test), improper installation or repair you didn’t know about, insufficient maintenance of covered items, and failures caused by rust, corrosion, or sediment.

Does OneGuard Cover Pre-Existing Conditions?

Yes — and this is OneGuard’s most unusual benefit. The contract covers unknown pre-existing conditions: problems that existed before coverage began but were not detectable by a visual inspection and simple mechanical test. Most competitors exclude all pre-existing breakdowns, so this is a genuine differentiator. Known problems you were already aware of are still excluded.

What Maintenance Services Does OneGuard Include?

OneGuard bundles household services most warranties never touch: A/C and heating system tune-ups, re-key service with garage remote re-programming, termite treatment, pest control treatment, lawn weed kill treatment, ceiling fan installation, dryer vent cleaning, window cleaning, and a pool maintenance visit. OneGuard also pays equipment disposal costs when a covered item is replaced — the “all-in-one home services” behind its marketing.

One Guard Home Warranty Cost and Service Fees

OneGuard prices plans annually rather than monthly. For a buyer’s 1-year plan on a single-family home, the official brochures list $399 (Sentinel), $499 (Centurion), and $599 (Guardian) in Arizona; $399, $549, and $699 in Texas; and $379, $499, and $599 in Nevada. The new construction plan covering years 2–5 runs $649, $799, and $949. Seller’s coverage combined with a buyer’s plan is priced at the same $399/$499/$599 tiers.

The service call fee — due each time a technician visits — is $69 in the Arizona brochure and $75 in the Texas brochure. Optional upgrades add to the annual premium: Preferred Upgrade $100, HVAC Equipment Incompatibility Coverage $90, washer/dryer set $80, kitchen refrigerator $60, and additional refrigeration units $50 each. On a monthly equivalent basis, Sentinel starts around $33/month — competitive for the coverage.

What the One Guard Home Warranty Does Not Cover

The exclusions work like most home warranties:

• Excluded Known pre-existing breakdowns. Only unknown, undetectable pre-existing conditions are covered — problems you knew about before coverage are excluded.
• Excluded Cosmetic and physical damage. Misuse, physical damage, and cosmetic issues are not covered — only wear-and-tear breakdowns (and the documented exceptions above).
• Excluded Routine maintenance. OneGuard pays for breakdowns, not the regular maintenance you’d do yourself (though the bundled tune-ups are the exception).
• Excluded Oversized homes and multi-units. Base pricing covers homes under 5,000 sq ft; larger homes, duplexes, triplexes, and fourplexes need custom pricing — call 888-896-0014.
• Excluded Items not in your contract. Only the items listed in your plan documents are covered; add-ons you didn’t buy (pool/spa, septic, well pump) are excluded.

How to File a One Guard Home Warranty Claim

1. Request service online at OneGuardHW.com or call 888-896-0014. You’ll need your policy number and zip code, or your name and zip code.
2. OneGuard approves the claim and selects a service contractor for you.
3. The contractor contacts you within four business hours — or within 48 hours if the claim arrives on a weekend or holiday for non-emergency service.
4. Pay the service call fee ($69–$75) when the contractor performs the covered repair.
5. 30-day workmanship guarantee: if the same item breaks again within 30 days, a contractor returns at no additional service fee.

For emergencies — interior flooding, complete loss of heating or cooling in extreme temperatures, or a substantial loss of electrical service — call immediately; emergency claims are prioritized.

Can You Transfer a One Guard Home Warranty?

OneGuard was built around real estate transactions: seller’s coverage protects the home during the listing period, and the buyer’s plan activates at closing. If you’re buying a home with a OneGuard plan included, confirm the plan tier with your agent. If you’re the seller, the seller’s coverage is bundled with the buyer’s plan at the $399/$499/$599 price points.

How to Cancel One Guard Home Warranty

Plans are annual contracts. Cancellation terms — including any fees and refund calculations — are in your contract documents. Because OneGuard’s pricing is annual rather than monthly, ask about the prorated refund formula before you cancel, and review it alongside any remaining service fee obligations.

One Guard Home Warranty FAQs

Conclusion

A one guard home warranty earns its niche: annual pricing that undercuts many monthly-billed competitors, genuinely unusual coverage for unknown pre-existing conditions and improper installation, and bundled maintenance services that other warranties charge extra for. The trade-offs are regional availability and the standard $69–$75 fee per visit.

If you’re in Arizona, Texas, or Nevada and your home’s systems are aging, Sentinel at ~$33/month equivalent is worth a quote — and Guardian makes sense if the washer, dryer, or fridge are on borrowed time. Get your quote at oneguardhomewarranty.com and confirm the exact terms for your state.
