Repair or Replace: A Framework That Is Not Just a Percentage

Every homeowner eventually faces this with a water heater, an air conditioner or a furnace. The advice online is usually a single percentage rule, which ignores most of what matters.

The factors that actually matter

1. Age relative to expected life

A failure at the start of a service life is a repair. The same failure near the end of it is a signal about what comes next.

Knowing the install date is the single most useful piece of information you can have, and most homeowners do not. Find it now, not during the failure.

2. What actually failed

Not all failures carry the same information.

• **A capacitor, a contactor, an igniter, a flame sensor, a thermostat** — inexpensive wear items. Repair, at almost any age.
• **A compressor or a heat exchanger** — the expensive core. On an older unit, that failure is usually the end.
• **A leaking tank** on a water heater is not repairable at all.
• **A refrigerant leak** depends on where it is and what refrigerant the system uses. Our guide on the R22 phase-out covers why that matters on older equipment.

3. Repair history

A first failure is an event. A third failure in two years is a pattern, and each repair is buying less time than the one before.

4. Efficiency and running cost

Older equipment costs more to run, and in North Texas the cooling season is long enough that the difference is real money rather than a rounding error.

5. How long you are staying

Genuinely relevant. Repairing to get through two more years before a move is a legitimate decision. So is replacing so the next owner is not inheriting a problem — that shows up in an inspection either way.

6. Consequence of the next failure

A water heater in an attic above finished ceilings has a much worse failure mode than one in a garage. An air conditioner failing in a Texas August with vulnerable people in the house is not just an inconvenience.

The case for repairing

• The unit is within its expected life.
• The failed part is a wear item.
• No pattern of repeated failures.
• The repair cost is modest relative to replacement.
• You are moving soon and the equipment is otherwise sound.

The case for replacing

• Past expected life with a major component failure.
• Multiple repairs in a short period.
• An obsolete refrigerant or unavailable parts.
• The failure mode of the next event is expensive — attic location, above finished space.
• The efficiency difference is large and you are staying.
• You want the certainty rather than the gamble.
