How do brand & quality tier change the parts cost?
Brand and tier adjust the parts portion only — never labour. Mirage, York, Whirlpool, Samsung, Mabe and Rheem form the mainstream core of the Mexican market — Mirage, the most widely installed minisplit brand, sets the parts-price reference the others are measured against. Below them sits the value tier — Comfort Star, Bair, Gree, Hisense, TCL, Midea and Goodman — with the cheapest, most widely stocked parts. Premium makers — Carrier, LG, Daikin, Trane, Lennox and Bosch — use pricier components, usually sold through the manufacturer's official channel. Pick a tier in the calculator for a class-typical estimate, or a specific Mexican brand to override it.

Is it worth repairing a ductless mini-split?
If the repair quote exceeds roughly half the price of a comparable new ductless mini-split — or the unit is well past its typical service life — replacement is often the better value. Localize the repair range above first, then compare.
Prices are state (estado)-level estimates based on labour-cost data, not fake city precision. See the methodology for the localization method and named sources.
