The 30-Second Verdict
Sub-Zero is the gold standard for built-in refrigeration in Florida — their dual-compressor design holds humidity precisely (critical in FL homes), and their 20-year compressor warranty means a Sub-Zero from 2005 still works in 2026. Their kitchen lineup (cooktops, ranges via the Wolf brand) is excellent but expensive. Thermador (owned by BSH/Bosch) offers a more complete luxury package — their refrigerators are good but not Sub-Zero-good, but their ranges, ovens, and dishwashers are best-in-class and their 'Kitchen Design Challenge' rebates often deliver $2,000–$5,000 in package savings. For Florida custom kitchens: Sub-Zero refrigeration + Wolf range, with Thermador dishwasher. For renovations on budget: full Thermador package leveraging the rebate.
Head-to-Head Breakdown
