Mitsubishi Diamond Contractor in Vancouver, WA.
Pacific Peak Mechanical is a Mitsubishi Electric Diamond Contractor serving Vancouver and Clark County. Mitsubishi trains its Diamond Contractors directly, and when we install and register a qualifying Mitsubishi system in an owner-occupied home, Mitsubishi extends the parts and compressor warranty to 12 years.

What a Mitsubishi Diamond Contractor is.
Mitsubishi Diamond Contractors are independent contractors who have received advanced training directly from Mitsubishi Electric Trane HVAC US, and they keep getting Mitsubishi's product, service and installation updates.
For a homeowner, Diamond status means two things:
- The extended 12-year factory warranty. Any Mitsubishi system registered within 90 days in an owner-occupied home gets 10 years on parts and the compressor (5 and 7 years if it is never registered). When a Diamond Contractor installs and registers it, qualifying models such as the FX and Smart Multi get the full 12-year parts and compressor warranty at no extra cost. The WX and HX lines are M-Series models too, but they top out at 10 years whoever installs them.
- Installs done the way Mitsubishi designed them. Mitsubishi's warranty only covers systems installed to its installation instructions, local building codes and permits, so we install to those instructions and run a start-up and safety check on every system.
The Mitsubishi systems we install.
As a Diamond Contractor, we install Mitsubishi's residential ductless lineup:
- M-Series ductless mini-splits, single-zone systems for one room, an addition, a bonus room, or a garage/ADU.
- P-Series and Smart Multi (MXZ-SM). P-Series covers Mitsubishi's ceiling cassette, ceiling-suspended, wall-mounted, horizontal-ducted and multi-position air handler systems. Smart Multi is the multi-zone line: one outdoor unit drives up to 8 indoor units through branch boxes, in any combination of wall-mount, floor-mount, ceiling cassette, or concealed slim-duct. Ideal for whole-home ductless conversions.
- Hyper-Heat (H2i) cold-climate models, such as the FX and the MXZ-SM48NLHZ Smart Multi, which we recommend when ductless will be the main heat. These deliver full rated heating capacity down to 5°F and keep heating well below that (the FX holds 100% at -10°F and runs to -22°F), with R-454B refrigerant on all current models.
See our guides to ductless mini-split installation and whole-home heat pump installation, or the complete equipment lineup with model numbers and specs.
Why Mitsubishi ductless makes sense in Vancouver.
Mitsubishi ductless heat pumps suit Vancouver's climate. The City of Vancouver sizes heating systems for a 22°F winter design day, and Mitsubishi rates its Hyper-Heat models for up to 100% heating capacity at 5°F. Mini-splits also skip duct losses, so they are often the most efficient option for homes with no ductwork, leaky ducts, or additions. Full comparison: ductless vs ducted systems.
What a Mitsubishi install with Pacific Peak includes.
- A proper load calculation. We run a Manual J to size each zone; oversized ductless heads short-cycle and dehumidify poorly.
- Direct-hire crews, no subcontractors. Every install is done by a trained Pacific Peak employee.
- Pulled permits and inspection. Every job is permitted through your city or Clark County.
- The factory warranty, registered for you. We register every system inside Mitsubishi's 90-day window. In an owner-occupied home that unlocks 10 years of parts and compressor coverage, or 12 years on qualifying models such as the FX and Smart Multi (the WX and HX lines top out at 10).
- Rebate handling. If you own the home and it heats with baseboards, wall heaters, ceiling cable or an electric furnace today, a Mitsubishi ductless install qualifies for Clark PUD's flat $900 ductless rebate, limit one per home. We compile and submit the paperwork. See our Clark PUD rebate guide.
- A written, itemized quote before any work begins.
