Is a home warranty worth it? What it covers (Texas homeowner guide)

Last reviewed: November 4, 2026.

Ask a room full of HVAC techs and plumbers about home warranties and you'll get mixed answers. Some like the steady work; others are tired of explaining to homeowners why a claim got denied. Both views are fair. A home warranty is a service contract, not magic, and it pays off for some households and not others. This guide walks through what these plans really cover, where they fall short, and how to decide whether one makes sense for your house.

1. Home warranty vs homeowners insurance

These two get confused all the time, but they cover different problems:

• Homeowners insurance covers sudden damage from events like fire, wind, hail, theft or a burst pipe that floods the floor. It pays to fix the damage, usually after a deductible. It generally does not pay to replace an air conditioner because the compressor wore out.
• A home warranty is a yearly service contract that helps pay to repair or replace covered systems and appliances when they fail from normal wear and tear. You pay a plan fee plus a service-call fee each time a technician comes out.

Example: a water heater tank rusts through and floods the utility room. Insurance may help with the flooring and drywall; a warranty may help with the water heater itself. Neither replaces the other, and your mortgage lender requires insurance, not a warranty.

2. What is typically covered

Plans differ, but most core plans include some version of the following:

• HVAC: central air conditioning, furnaces and heat pumps, often including parts like blower motors, capacitors and thermostats. In Texas this is the item most people care about, because an AC failure in August is both urgent and expensive.
• Water heater: tank-type gas or electric units are common; tankless units may be covered or may need an add-on.
• Plumbing: leaks and breaks in interior supply and drain lines, stoppages that can be cleared through an accessible cleanout, toilets and some fixtures.
• Electrical: interior wiring, panels, outlets and switches.
• Appliances: often dishwasher, range or oven, built-in microwave, garbage disposal, and on some plans refrigerator, washer and dryer.

Pools, spas, well pumps, septic systems, second refrigerators and roof leaks are commonly sold as optional add-ons, if offered at all. Read the contract's list rather than the marketing summary.

3. Common exclusions to read first

Most disappointment with home warranties comes from exclusions people didn't read. Look for these:

• Pre-existing conditions. Problems that existed before coverage started, or that a tech decides were developing for a long time, are usually excluded. A waiting period after signup is also common.
• Improper maintenance. A unit that failed because of a never-changed filter, a clogged condensate line or a water heater full of sediment can be denied. Keep receipts and dated photos of your maintenance.
• Code upgrades and modifications. If a repair requires bringing equipment up to current code, adding permits, moving a unit, changing refrigerant type or modifying ductwork, those extra costs often fall on you. This matters with older AC systems and the newer refrigerants.
• Coverage caps. Plans limit what they'll pay per item, per claim or per year. A full HVAC replacement can easily exceed a cap, leaving you to pay the difference.
• Secondary damage and access. Water damage from a leak, or cutting and patching drywall to reach a pipe, is often excluded or limited.
• Cosmetic issues and non-standard parts. Dents, finishes and hard-to-find parts may not be covered fully.

4. Service-call fees, caps and how claims work

Every time a technician comes out, you pay a service-call fee (sometimes called a trade call fee). If your AC needs two visits for the same failure, check whether you pay once or twice. The warranty company usually picks the contractor, so you may not get your preferred local company, and the warranty company decides between repair and replacement.

When you compare plans, look at the total picture, not just the monthly price:

• Yearly plan cost plus the service fee you'd expect to pay in a typical year.
• The cap on HVAC and water heater claims, since those are the expensive ones.
• Whether replacements are "like-kind" (similar capacity and efficiency) and who pays for code-required extras.
• Cancellation terms and the waiting period before you can file a claim.

We don't recommend any particular warranty company, and we don't list plan prices, fees or caps because they change and vary by address. Get quotes from several providers, compare them side by side, and read the full sample contract for your state, including exclusions and caps, before you buy.

Claim tips from the contractor side

• File early. Report a problem as soon as you notice it. Waiting can turn a small repair into a "neglect" denial.
• Describe symptoms, not diagnoses. "AC is running but blowing warm air" is better than guessing the part.
• Keep maintenance records. Filter receipts, tune-up invoices and water heater flush dates are your best defense against a maintenance-based denial.
• Ask for the denial reason in writing, with the contract section cited, if a claim is declined.
• Get the tech's findings. Ask what failed and why, and take photos of the data plate and the failed part.
• Know your out-of-pocket. Before approving work, ask what's covered, what isn't, and what you'll owe beyond the service fee.

5. When a home warranty is worth it

• Older systems. If your AC, furnace or water heater is past the middle of its typical life (often 10 to 15 years for HVAC and around 8 to 12 for a tank water heater), a plan can soften the cost of the repairs that come with age, as long as the unit is still working and maintained.
• New home buyers. Buying a resale home means inheriting systems you didn't choose and don't know. A warranty can help through the first year while you learn the house. Sellers sometimes pay for one at closing, so ask.
• Rental properties. Landlords like having one number to call and a predictable service fee, especially when they don't live nearby.
• Thin cash cushion. If a surprise repair bill of a few thousand dollars would be a real hardship, spreading that risk can be worth the plan cost.

6. When it probably isn't

• New systems. If your HVAC and water heater are only a few years old, manufacturer parts warranties (and any labor warranty from your installer) already cover much of what could go wrong.
• Solid emergency fund. If you can pay for a repair without stress, "self-insuring" by putting the yearly plan cost into savings often comes out ahead over time.
• You want your own contractor. If you already have an HVAC company or plumber you trust, being assigned a contractor can be frustrating.
• Known problems. If a system is already failing, a warranty is unlikely to cover it because of pre-existing condition rules.

7. Maintenance still matters (and protects your claims)

A warranty doesn't replace upkeep. In fact, maintenance is what keeps claims from being denied. The basics:

• Change your furnace/AC filter on schedule, using the right size and rating. Our furnace/AC filter sizes and MERV guide covers how to read the size and pick a MERV level.
• Get an annual HVAC tune-up and keep the invoice. If you're planning a replacement soon, read our heat pump sizing guide, furnace AFUE: 80% vs 96% guide and central AC vs DIY mini-split before you get quotes.
• Flush water heaters as the manufacturer recommends. Texas hard water builds scale fast; see how to flush a tankless water heater, and check Texas water hardness by city to see how hard yours is.
• Protect electronics on HVAC boards and appliances with a whole-house surge protector.

FAQ

Does a home warranty replace homeowners insurance?

No. Insurance covers sudden damage from events like fire, storms and theft; a warranty helps with systems and appliances that wear out. Most homeowners with a warranty still need insurance.

Will a home warranty cover my old AC?

Age alone usually doesn't exclude a system if it's working when coverage starts, but pre-existing problems, poor maintenance and code-upgrade costs typically aren't covered. Check the HVAC cap in the contract, because a full replacement can exceed it.

Can I pick my own contractor?

Usually the warranty company assigns a contractor. Some plans allow exceptions or reimbursement in certain cases; read the contract.

What does a service-call fee cover?

It's the fee you pay each time a technician is dispatched for a claim. It doesn't cover items the contract excludes or costs above the cap.

Is a home warranty worth it when buying a house in Texas?

It can be, especially for an older resale home with original HVAC and water heater. Ask whether the seller will pay for one at closing, and still get a thorough inspection.

Can I cancel?

Most plans allow cancellation, sometimes with a fee or prorated refund. Terms vary, so read them before you sign.

Bottom line

A home warranty is a budgeting tool, not a guarantee. It makes the most sense for older systems, recent buyers, rentals and households without a large repair fund, and the least sense for new equipment or owners who can comfortably cover a repair. Whatever you choose, keep up with maintenance, keep your records, and read the exclusions and caps before you sign.
