It is Mitsubishi Electric’s top tier for independent dealers, recognizing training, installation quality and customer satisfaction. Homeowners who use a Diamond Contractor can qualify for Mitsubishi’s extended 12-year limited warranty.

Yes. Every Mitsubishi Electric ductless mini-split is a heat pump: the same system provides both heating and air conditioning by moving heat in or out of your home. “Mini-split” describes the equipment layout — a compact outdoor unit and one or more indoor units — while “heat pump” describes how it heats and cools.

Cost depends on the number of zones, the indoor unit styles, line-set routing, electrical work and permits. A free in-home estimate gives you a written, itemized price with the rebates you qualify for already shown.

Diamond Contractors are trained directly on Mitsubishi Electric equipment and installation practices, and their installations can qualify for Mitsubishi’s extended 12-year parts and compressor limited warranty. Correct sizing, line-set routing and commissioning matter as much as the equipment itself.

Yes. Mitsubishi Hyper-Heating INVERTER® (H2i®) systems are designed for climates far colder than ours, so a properly sized system handles both heating and cooling year-round as an all-electric replacement for a gas furnace.

Yes. A heat pump both heats and cools from the same system, so one Mitsubishi installation replaces a separate furnace and air conditioner.

Ductless mini-splits are best for homes without ductwork, additions, ADUs and Eichlers, and for room-by-room control. A ducted Mitsubishi heat pump makes sense when your existing ducts are in good shape. Many Peninsula homes combine both on one multi-zone outdoor unit.

Yes. Eichlers typically have flat roofs, no attic space and aging radiant floor heat, so low-profile Mitsubishi wall-mounted or floor-mounted ductless units are a natural fit. They add cooling and efficient heating without major construction.

No. Ductless mini-splits mount on the wall, floor or ceiling and connect to an outdoor unit through a small line set. If you already have good ducts, a ducted Mitsubishi system can use them.

Select Mitsubishi Electric indoor units operate as low as 19 dB(A), quieter than a whisper, which makes them well suited to bedrooms, nurseries and home offices.

Yes. With the Comfort app by Mitsubishi Electric (formerly kumo cloud®) you can set temperatures, modes and schedules for each zone from a smartphone, tablet or web browser, and it works with popular voice assistants.

Peninsula Clean Energy and BayREN offer incentives for eligible customers switching to heat pumps, and 0% financing may be available. Programs change often, so your written estimate lists every incentive you currently qualify for.

Cost depends on the number of zones, the indoor unit styles, your electrical service and the installation details. A free in-home estimate gives you a written, itemized price with the rebates you qualify for already shown.

Clean or check the indoor unit filters regularly and schedule professional maintenance about once a year to clean coils, check refrigerant and keep the warranty in good standing. Our Extended Service Agreement covers routine maintenance. See the Extended Service Agreement.

It depends on the number of zones and the home. Your written proposal includes a project timeline before any work begins.
