Replacement lookup
Mini-split replacement finder
Enter the model number from an old indoor or outdoor unit nameplate. If there is a documented current-generation successor in our catalog, the tool links it. If not, it says so and routes you into sizing and current product filtering.
Enter the indoor or outdoor unit model exactly as printed on the nameplate. Hyphens, spaces, and case do not matter.

What replaced my mini-split model?
Most shoppers who type an old mini-split model number are reading the nameplate on a system they already own. That old number is often an R-410A model, while current catalogs have moved to R-32 or R-454B equipment. This lookup connects only documented same-brand, same-line successors, and it says no direct replacement when the evidence is not strong enough.
The result is intentionally not a one-page-per-old-SKU catalog. It is a lookup: enter the indoor or outdoor model number, then use the documented successor when one exists or move into sizing and product filtering when it does not.
Why R-410A matters
R-410A systems can still be serviced, but R-410A is an HFC covered by the federal AIM Act phasedown. As new HFC production and consumption step down, refrigerant-heavy repairs on older equipment can become a bigger part of the repair-or-replace decision.
A small non-refrigerant repair may still make sense. A large leak repair, coil replacement, compressor repair, or repeated refrigerant loss on a 10- to 15-year-old R-410A system deserves a harder look against a current R-32 or R-454B replacement.
How the lookup decides
- Strong mapping - manufacturer documentation names the successor explicitly.
- Documented line successor - the brand and line pair are documented, and capacity plus voltage match.
- Same line, new refrigerant - brand, line, capacity, and voltage match, with only the refrigerant generation changing.
- No direct replacement - there is not enough same-brand and same-line evidence to recommend a successor.

Frequently asked questions
- Can I replace an R-410A mini-split with an R-32 or R-454B model?
- Often yes, but it is not a refrigerant-only swap. The indoor unit, outdoor unit, controls, line-set rules, electrical requirements, and installation instructions all matter. Use a documented successor as the product starting point, then have a licensed installer confirm compatibility and code requirements.
- Why does the lookup sometimes say no direct replacement?
- Because a wrong replacement recommendation is expensive. The lookup does not map across brands, across product lines, or by capacity alone. If we cannot defend the successor from documented brand and line evidence, the result routes you to sizing and current product filtering instead.
- Should I repair or replace an old R-410A mini-split?
- It depends on age, leak history, part availability, and repair size. Filters, controls, and minor electrical repairs can still be reasonable. Large refrigerant-side repairs on older R-410A systems are different because HFC supply is phasing down and repeat leak work can become expensive.
- Which model number should I enter?
- Start with the outdoor unit nameplate. Indoor model numbers can be shared across standard and high-heat outdoor units, so the outdoor model is usually the cleaner replacement clue. Hyphens, spaces, and capitalization do not matter.
