The truth about home warranties.

Written by an HVAC contractor who has worked both sides of the warranty system. Most homeowners do better without one.

Home warranties are not always a scam, and some homeowners do come out ahead. A few of our favorite customers swear by theirs, and some warranty companies are better than others. Still, most Houston-area homeowners pay too much for less service than they think they're buying. Here is why, with the math.

What a home warranty actually is

It is an insurance product, and Texas regulates it as one. The company makes money by collecting more in premiums and service fees than it pays out in claims, and the fine print is written to keep payouts down. Nothing sinister about that. Insurance works that way. The trouble is that customers think they bought "service when something breaks," and the contract they signed says "covered repairs subject to exclusions."

Where the gap shows up

1. Speed

You call the warranty company, and it opens a ticket with its dispatch network. In many cases a network contractor calls you back a day or two later. The first open appointment can be 3 to 7 days out. In a Houston August, that is a long time without AC.

We regularly hear from people who waited four days without a callback and now want us to fix it on their own dime. We go, and we feel for them.

2. The contractor pool

Warranty companies pay a flat per-call rate well below normal market rates. Most established contractors in our area turn that work down because it doesn't pencil. The ones who take it tend to be new and building hours, running a high-volume model that depends on upselling non-covered items, or cutting corners to make the numbers work.

There are good contractors in the warranty pool. On the whole it skews newer and quicker, and less likely to spend time on a hard diagnosis.

3. The "covered parts" fine print

Common exclusions in standard contracts:

  • Code upgrades. If your old lineset is too small for a code-compliant new install, that part is on you.
  • Refrigerant changes. Expect plenty of "your old refrigerant isn't covered" calls as equipment moves from R-410A to R-454B.
  • Pre-existing conditions. If someone can argue the problem started before the policy, it's excluded.
  • Improper maintenance. A loaded filter or a filthy coil can get the claim denied.
  • Permit fees and haul-away are commonly not covered. Neither are electrical disconnects, drain lines or ductwork.
  • "Like for like" replacements. When an 18-year-old single-stage unit dies, you get a 14-SEER single-stage replacement, even if the house would do better with variable-speed.

4. The "least-expensive repair" pattern

A warranty company makes more money repairing than replacing. We have seen 19-year-old units repaired three times in one summer because each repair cost less than the payout cap. Every one of those repairs was technically valid. For the homeowner, replacing the unit was the right call. For the warranty company, patching it was.

The actual math for a typical Pearland home

Say you have a 6-year-old AC and a 10-year-old furnace.

With a home warranty

  • Annual premium: $500
  • One service call (clogged drain line): $100 service fee
  • One service call (capacitor replacement, "covered" except $80 in non-covered diagnostic time): $100 service fee + $80 = $180
  • Total year: $780

Without a warranty, with a service membership

  • Membership: $300 a year (two tune-ups, priority dispatch, service-call fee waived, 10 percent off repairs)
  • Drain line cleared during the summer tune-up: $0
  • Capacitor replacement: $180 to $320, less the 10 percent member discount, so $162 to $288
  • Total year: $462 to $588

On top of that, you knew the tech, the diagnosis was thorough, the appointment was the same week, and your next call goes to the front of the line too.

When a home warranty might make sense

  • You bought a home with old systems and want a backstop for the first year while you figure out what you need.
  • You own a rental from out of town and need a hands-off way to get repair calls handled.
  • You are very risk-averse and would rather pay a predictable monthly cost than an occasional repair bill.

Even then, read the contract closely. Assume every exclusion will be enforced.

What we do for our members instead

Clear Advantage is one flat price, $25 a month or $300 a year, however many systems the home has. It includes:

  • Two full tune-ups a year (heating and cooling)
  • Priority dispatch ahead of non-members, emergencies included
  • No service-call fee
  • 10 percent off repairs and new equipment
  • A repair history we keep on file, so the next tech knows your system

Membership doesn't pay for repairs the way a warranty claims to. You pay for a repair at a discount when it happens and skip the premiums. For most homeowners with reasonably maintained systems, that comes out ahead. Nights and weekends cost the same as weekdays for members and non-members alike.

Frequently asked questions

Are home warranties worth it for HVAC coverage in Houston?

Usually no. A year of premiums plus per-claim service fees often costs more than a tune-up and a small repair fund would. The bigger problem is who shows up. Warranty companies pay so little per call that their contractor pool tends to be thin and slow.

What is the alternative to a home warranty for HVAC?

A service membership with a contractor you know. You get annual tune-ups and priority dispatch, plus a repair discount from people who have seen your system before. Ours costs $300 a year, against the $400 to $700 a home warranty typically runs.

My realtor says home warranties protect new homeowners. Is that fair?

For first-time buyers with no service relationships, a warranty can feel like a safety net. Some realtors do earn a small commission on the warranty sale. New owners often find the limits the first time they file a claim.
