Mitsubishi Electric is the ductless mini-split leader, with Hyper-Heat cold-climate performance and excellent multi-zone systems. Our top pick for homes without ducts and for additions. Owner Andrew Kuznetsov completed Mitsubishi Electric's M- and P-Series Essentials in Sacramento (May 2026) and then the Advanced M- and P-Series Service factory training at their Los Angeles center (June 2026), so we size, install, and service their ductless and multi-zone systems to spec. We became a Mitsubishi Electric Diamond Contractor in October 2026.

Mitsubishi: common questions
Does Mitsubishi cost more than a ducted system for the same coverage?
Per zone, yes, ductless multi-zone usually carries a higher equipment cost than extending ducted air, and concealed-duct heads add labor on top. The payback is no demolition and independent control per room. As a Mitsubishi Electric Diamond Contractor, we register your M-Series or P-Series system for the Mitsubishi Electric 12-year parts and 12-year compressor limited warranty (the HM, WR, HX and WX wall-mounted series top out at 10 years). We register all indoor and outdoor units within 90 days of installation. This coverage applies to a single-family home while the original owner continues to live there and is not transferable. Our standard workmanship warranty is 2 years. Repairs carry a 1-year warranty.
What does the warranty cover on a Mitsubishi install?
As a Mitsubishi Electric Diamond Contractor, we register your M-Series or P-Series system for the Mitsubishi Electric 12-year parts and 12-year compressor limited warranty (the HM, WR, HX and WX wall-mounted series top out at 10 years). We register all indoor and outdoor units within 90 days of installation. This coverage applies to a single-family home while the original owner continues to live there and is not transferable. Our standard workmanship warranty is 2 years. Repairs on an existing unit carry a one-year warranty. The $99 diagnostic fee is credited toward the repair.
Should I just seal my old ducts instead of going ductless?
Often yes. If the ducts test reasonably and the runs are intact, sealing is the cheaper path and we'll recommend it. Mitsubishi ductless wins when leakage is high enough that a retrofit costs about as much as a mini-split, or when a room has no duct service at all. We put both numbers on the estimate.
My AC is old, repair or replace, and where does Mitsubishi fit?
If the central system is failing, we run a Manual J and quote a properly sized ducted replacement rather than reaching for ductless by default. R-22 systems with refrigerant leaks usually pencil toward replacement. Mitsubishi fits the targeted rooms, not the whole-house load. As a Mitsubishi Electric Diamond Contractor, we register your M-Series or P-Series system for the Mitsubishi Electric 12-year parts and 12-year compressor limited warranty (the HM, WR, HX and WX wall-mounted series top out at 10 years).

Our standard workmanship warranty is 2 years. Other ducted replacements carry 10-year parts, with labor at 2 years standard (10 years on our maintenance plan). Repairs carry one year.
