We make money on repairs. So take it seriously when a repair company tells you: sometimes the right answer is to stop repairing. Here's the framework we walk owners through, with the honest version of each factor.
Start with age and duty
Commonly used planning figures in the trade: reach-ins run roughly 10 years of useful life, walk-ins roughly 15, with hard-worked, poorly maintained units on the low side and well-maintained ones beating the average. These are planning numbers, not promises — we've serviced 20-year-old walk-ins that were worth every repair, because they'd been maintained.
The 50% rule
The old trade rule still holds: if a repair costs more than about half of replacement — especially on a unit past the midpoint of its life — replacement usually wins. A compressor on a 14-year-old walk-in is the classic example. A door gasket on the same unit is nowhere near the line.
The R-22 question
If your equipment still runs on R-22 refrigerant, the math changes. New production and import of R-22 have been banned in the U.S. since 2020; what's left comes from recovered and stockpiled supply, and its price reflects that. A major refrigerant-side repair on an R-22 system means paying premium prices to extend a platform the industry has already left. Ask your tech what refrigerant your equipment uses — it's on the nameplate.
Energy is part of the bill
An aging unit with tired gaskets and a struggling compressor doesn't just risk failure — it runs longer hours at higher draw, every month, on your electric bill. Newer equipment is measurably more efficient. This rarely decides the question alone, but it belongs in the math.
What downtime actually costs you
The repair invoice is the small number. The big numbers are the walk-in full of product on a Friday, the health-inspection finding, the Saturday service you couldn't serve. If a unit has begun failing repeatedly, each individual repair may make sense while the pattern doesn't. Three calls on the same box in a year is a pattern.
Our honest rule
When you call us for an estimate, you'll get both numbers when it's close: what the repair costs, and what we'd do if it were our equipment. Sometimes that answer is “don't pay us — replace it.” That policy is fifty years old, and it's why our customers are too. Talk it through with us at 501-548-2374.
Frequently asked questions
How long should a commercial walk-in cooler last?
Roughly 15 years is a common planning figure, with maintenance being the biggest variable. Regular coil cleaning, gasket replacement, and prompt small repairs routinely push units past the average.
What is the 50% rule for equipment replacement?
If a repair costs more than about half the price of replacing the unit — particularly when the unit is past the middle of its expected life — replacement is usually the better spend.
Why are R-22 repairs so expensive?
New R-22 hasn't been produced or imported in the U.S. since 2020, so remaining supply is recovered or stockpiled and priced accordingly. Major refrigerant-side repairs on R-22 systems often argue for replacement instead.
