How we calculate this

The arithmetic: repair quote ÷ replacement quote × 100 gives the repair’s share of replacement cost. That percentage does not predict savings, reliability, or the cheapest option over time.

The interpretation: the 15% and 45% cutoffs below are FrugalWatt’s editorial rules of thumb. They are not an industry standard, an ENERGY STAR recommendation, or a professionally validated model.

  • Below 15% of replacement cost, the repair looks small enough to investigate first—even on older equipment.
  • At 45% or more, collect replacement quotes before deciding.
  • Between those points, compare the scope of both quotes and ask about repair reliability and warranties.
  • Age adds context only. It never changes the price-based suggestion or predicts how long your equipment will last.
  • Without a replacement quote, we show an example comparison and suggest getting a quote. We do not recommend repair or replacement from an invented price.

Example prices: the amounts below are round-number scenarios, not measured national averages or local estimates. They are only used when a replacement quote is missing. Installation scope and location can change real prices substantially.

Furnace
$7,000 example
Boiler
$10,000 example
Central AC
$7,500 example
Heat pump
$12,500 example
Water heater
$2,500 example

Worked example, not a customer story: a $1,875 repair quote divided by a $7,500 replacement quote is 25%. That puts the example in our “compare both” band. It does not tell you which option will last longer.

A low-cost repair can still be poor value if it does not resolve the underlying fault. This comparison does not include future failures, warranties, running costs, financing, or rebates.

What you can check for yourself

The guidance

ENERGY STAR: when to consider replacement

Age, frequent repairs and comfort problems are reasons to talk with a contractor—not a diagnosis of your equipment.

FTC: choosing a contractor

Get written estimates with the work and price spelled out. A low bid alone is not enough to compare jobs.
