Expect $5,000-$7,500 installed for a single zone from a certified installer. | Daikin's 12-year warranty requires installation by a licensed contractor plus registration, so treat this as pro-install gear. Installed single-zone quotes typically run $4,500-$7,000. |
| Warranty | 5-year parts / 7-year compressor standard; 12 years parts and compressor when installed and registered by a Mitsubishi Diamond Contractor. | 12-year parts limited warranty when registered within 60 days of a professional install; unregistered coverage drops to the 5-year base term. |
