Repair or replace is the most expensive decision a homeowner makes on almost no information. The appliance quit yesterday, a technician has just quoted you a number, the food is thawing, and you have maybe an hour to decide whether to spend $200 on a machine you do not trust or several times that on a machine you have not researched. Most people resolve it by feel, and feel is wrong in both directions — perfectly repairable five-year-old dishwashers get hauled to the curb every week in Houston, while fourteen-year-old refrigerators get $400 compressors installed months before the rest of the sealed system follows. This guide gives you the two tests that settle it, the appliance-by-appliance thresholds, and the four Houston-specific factors that shift the answer.
This is the decision guide in Unitech’s appliance repair series. For the underlying rate card, see the 2026 appliance repair cost guide.
Key Takeaways
- Two tests, and both have to fail before you replace. The repair has to cost more than half of a comparable new unit and the appliance has to be past roughly two-thirds of its expected service life. One without the other is not a replacement case.
- The 50% rule alone gets it wrong constantly. A $340 repair is more than half the price of a cheap replacement dishwasher, but on a four-year-old machine it is still the right call — the replacement resets nothing you are actually paying for.
- Built-in appliances change the math completely. Replacing a panel-ready built-in refrigerator or a wall oven means cabinetry, trim, and often a carpenter — costs that never appear on the appliance price tag and that routinely double the real replacement number.
- Some repairs are almost always worth authorizing. Heating elements, thermal fuses, door seals, drain pumps, igniters, and thermostats are cheap, discrete, and do not signal a machine near the end of its life.
- Sealed-system refrigeration and washer transmissions are the two real replacement triggers. They are the most expensive labor on the board, and on an older unit they usually mean the rest of the machine is close behind.
- Check the warranty before anything else. Manufacturer coverage on a newer appliance can make the entire question moot, and homeowners in newer builds across Fort Bend and Harris County forget they still have it.
What This Decision Covers — and Why It Matters Now
Houston’s housing stock creates an unusual concentration of this problem. The metro’s construction boom means an enormous number of homes were finished between 2005 and 2015, and the original builder-grade appliance packages in those homes are now hitting 11 to 20 years old simultaneously. At the same time, kitchen remodels through the 2010s pushed built-in and panel-ready appliances well beyond luxury neighborhoods, which means far more households now face a replacement decision that involves cabinetry rather than a delivery truck.
This guide covers the two-test framework, what it produces for each major appliance, the repairs that are worth authorizing on sight, the ones that usually are not, the replacement costs nobody quotes you, and how to run the check yourself before a technician arrives.
The Two Tests
Test one: the 50% cost rule
If the total repair — labor plus parts — exceeds half the cost of a comparable new unit, the repair fails test one. “Comparable” is doing real work in that sentence. Compare against a machine of similar capacity, configuration, and tier, not against the cheapest unit on the floor. A 48-inch built-in refrigerator does not have a $900 comparable.
Using Unitech’s published labor rates, most single-component repairs on standard brands land between $145 and $365 before parts. That is well under half of a comparable replacement for nearly every appliance category, which is precisely why the second test exists.
Test two: the two-thirds lifespan check
Every appliance has an expected service life. If the machine is past roughly two-thirds of it, a significant repair is buying time on a system whose other components are the same age and have seen the same use. Full figures are in the appliance lifespan reference, but the short version:
| Appliance | Typical service life | Replacement-consideration age |
|---|---|---|
| Gas range | ~15 years | 10+ years |
| Refrigerator | ~13 years | 9+ years |
| Electric range | ~13 years | 9+ years |
| Washer | ~10–13 years | 7+ years |
| Dryer | ~10–13 years | 7+ years |
| Dishwasher | ~9 years | 6+ years |
| Microwave | ~9 years | 6+ years |
Reading the two tests together
- Passes both (cheap repair, young machine): repair, without hesitation.
- Fails cost, passes age: usually still repair. An expensive repair on a young appliance is buying most of a service life.
- Passes cost, fails age: repair, but treat it as borrowed time. A $165 dryer element on a twelve-year-old machine is fine; start budgeting.
- Fails both: replace. This is the only combination that clearly says stop spending.
Repairs Worth Authorizing Almost Every Time
These failures are discrete, inexpensive relative to the machine, and carry no signal about the rest of the appliance’s health.
- Heating elements and igniters. A dryer element, an oven bake element, or a gas oven igniter is a wear part. Its failure says nothing about the machine. See why dryers stop heating.
- Thermal fuses and thermostats. Safety components that do their job and open. Cheap, fast, and often symptomatic of something correctable, such as a restricted dryer vent.
- Door seals and gaskets. A refrigerator gasket that no longer seals makes the compressor run continuously — the repair pays for itself in reduced wear on the expensive component.
- Drain pumps and inlet valves. Standard failure points on washers and dishwashers, at the low end of the labor range. Dishwasher repair labor runs $145–$195.
- Lid switches, door latches, and hinges. Mechanical wear items, quick to replace.
- Control boards on appliances under seven years old. The part is not cheap, but on a young machine it is still comfortably inside the 50% rule.
Repairs That Usually Mean It Is Time
- Sealed-system refrigeration on a refrigerator past nine years. Compressor, evaporator, or refrigerant circuit work sits at the top of the refrigerator repair range at $175–$365 in labor, plus a substantial part. On an older unit, the other sealed-system components have the same runtime. If the fresh-food side is warm and the compressor is running hot, read the nine causes of a refrigerator not cooling before assuming the worst — several are cheap.
- Washer transmission or bearing failure past seven years. The highest labor on washing machine repair at $165–$265, and a job that involves substantially disassembling the machine. Bearing failure in particular usually means water has been getting where it should not for a long time.
- A second major failure inside twelve months. Two unrelated significant repairs in one year is the machine telling you something the individual quotes do not.
- Any repair requiring a discontinued part. If the component has to be sourced from a salvage supplier, the next one will be worse.
- Cabinet or tub corrosion. Rust through a washer tub or a refrigerator liner is structural. There is no repair.
The Replacement Costs Nobody Quotes You
The sticker price on a new appliance is the beginning of the number, not the number. Before you treat replacement as the cheaper path, add:
- Delivery, haul-away, and installation. Rarely free once you are past the entry tier, and gas or water connections are typically billed separately. Professional installation exists as a line item for a reason — a dryer vented into a wall cavity or a water line run without a proper shutoff creates the next problem.
- Cabinetry and trim on built-ins. This is the big one. Built-in refrigerator openings, wall oven cutouts, and panel-ready fronts were sized to a specific model. Current models are frequently not the same dimensions, which turns an appliance purchase into a carpentry project. In Bellaire and the remodeled kitchens across established Sugar Land neighborhoods, this alone routinely makes repair the better decision on appliances well past their nominal life.
- Lead time. A repair is often same-day. A specific built-in configuration can be weeks out. Weeks without a refrigerator has a real cost.
- Electrical or gas modifications. Newer units sometimes need a different circuit, a different gas connector, or a dedicated water line that the old installation did not have.
- The learning curve. Minor, but real: new control schemes, new cycle behavior, and a new set of quirks to discover.
Four Houston Factors That Shift the Answer
Hard water shortens water-contact appliances
Houston-area supply is classified as hard, and mineral scale is unforgiving to dishwashers, ice makers, and washer inlet valves. In Richmond, Rosenberg, and the municipal utility district systems across west and southwest Harris County, water-contact components frequently fail earlier than the national averages suggest. That pulls the two-thirds lifespan threshold forward for those specific appliances — see what hard water does to appliances.
Power events damage control boards
Storm outages, restoration surges, and the hard freezes that periodically take the grid down are hard on electronics. An appliance that failed within days of an outage may have a board problem rather than a mechanical one — a materially different repair-versus-replace calculation, because a board on an otherwise healthy machine is often worth doing.
Humidity and garage installations
Second refrigerators and freezers in unconditioned garages are a Houston institution, and they run in ambient conditions the manufacturer did not design for. Those units age faster. Judge them on runtime, not on the calendar.
Newer builds may still be covered
Across the newer sections of Missouri City and the growth corridors, a large share of appliances are still inside manufacturer coverage, and homeowners forget. Check the purchase date and the warranty terms before authorizing anything. A covered repair costs you nothing, and an unauthorized third-party repair can void what is left.
How to Run the Check Before the Technician Arrives
Find the manufacture date
The rating plate carries it — inside the refrigerator compartment, on the dishwasher’s inner door edge, or behind the dryer door. Many serial numbers encode the month and year directly. This is the single most decision-relevant fact you have, and it takes 60 seconds.
Check warranty status
Locate the purchase date, then check the manufacturer’s terms for that model. Sealed systems in particular often carry longer coverage than the rest of the appliance — five to ten years is common on refrigeration.
Price a genuine comparable
Not the cheapest unit that fits. Match capacity, configuration, fuel type, and finish. For built-ins, price the model that fits your existing opening, and if none does, get a real number for the cabinetry work.
Get the repair quoted as two numbers
Labor and parts, separately, in writing. Unitech publishes labor by appliance on the pricing page, so you can sanity-check the labor half before the technician arrives.
Ask the technician the direct question
“If this were your appliance, would you fix it?” A company that makes money on repairs and still tells you to replace is giving you the honest answer. Unitech does not charge labor when the fault turns out to be external to the appliance at all — a tripped breaker, a dead outlet, or a clogged house drain — which is the same principle applied earlier in the process.
What Getting This Wrong Costs
Replacing a repairable appliance is the most common error and the most expensive. A five-year-old dishwasher with a failed drain pump is a $145–$195 labor repair. Replaced instead, it is a new machine, delivery, installation, and disposal — for a unit that had four good years left.
Repairing a machine that was finished is the mirror error. A major repair on an appliance past two-thirds of its life, followed by a different failure six months later, is the first repair written off entirely.
Deferring the decision has its own price. A refrigerator struggling to hold temperature runs its compressor nearly continuously, which is exactly how you convert a cheap thermostat or gasket repair into a sealed-system replacement. A dryer that needs two cycles is running a restricted vent, which is a fire risk, not an annoyance.
Buying on the wrong comparable quietly inflates the replacement side of the equation. Homeowners in Stafford and across the older Fort Bend subdivisions frequently compare a solid 15-year-old appliance against an entry-level unit that will not last as long as the one being discarded.
