Ducted Heat Pump Systems
For homes with usable ducts, or where a hidden whole-home system is the better fit. Ducted Mitsubishi gear can heat and cool through a normal central-air layout without turning every room into its own job.
12 Year Parts & Compressor Warranty
Mitsubishi Electric Diamond Contractor
3rdGen is a certified Mitsubishi Electric Diamond Contractor. We design and install heat pumps for Bay Area homes with factory training behind the work and longer warranty options on qualifying systems.
Mitsubishi System Options
One Mitsubishi platform. A few ways to make the house comfortable.
Mitsubishi is not a single setup. Depending on your home, ductwork, layout, and how you use the rooms, we can go ducted, ductless, multi-zone, or a mix of all three.

-
Ductless Room-by-Room Systems
For additions, older homes, stubborn rooms, or places where new ductwork does not make sense. Indoor units give you targeted heating and cooling without opening up the whole house.
-
Multi-Zone Systems
One outdoor unit can serve several rooms with their own indoor units and controls. Useful when different parts of the house have different loads, schedules, or comfort problems.
-
Mixed Ducted + Ductless Designs
Some houses need both. Ducted for the main living areas, ductless for additions, upper floors, offices, or hard rooms. We design around the house instead of forcing one answer everywhere.
You do not need to pick a system type before you call. We look at the house and recommend what fits the project, not whatever is easiest to sell.

12-year parts and compressor coverage on qualifying installs.
Working with a Diamond Contractor unlocks longer Mitsubishi warranty options than a standard install. On qualifying systems, that can mean 12 years on parts and the compressor. We handle registration and walk you through what keeps coverage active.

FAQ
Common Questions
Straight answers on Diamond Contractor status, Mitsubishi systems, and what happens after you get in touch.
What does it mean to be a Mitsubishi Electric Diamond Contractor?
Diamond Contractors finish Mitsubishi factory training and meet program standards for design and install quality. That gets our team manufacturer resources, training, and support when a job is more than a basic equipment swap.
What warranty comes with a Mitsubishi Diamond Contractor installation?
Qualifying Mitsubishi installs can include extended parts and compressor coverage, often up to 12 years when the equipment and install meet program rules. We confirm exact coverage for the system we recommend before work starts.
Do you only install Mitsubishi equipment?
Mitsubishi is our main residential heat pump line because of the equipment range, controls, cold-weather performance, and support. It is not the right answer for every house. We start with the home and the project, then recommend what fits.
Can a Mitsubishi heat pump replace my gas furnace?
In a lot of Bay Area homes, yes. A well-chosen heat pump can handle heating and cooling in one system. Whether a conversion makes sense depends on the house, ducts, electrical service, comfort goals, and the design we put together.
Can Mitsubishi work with my existing ductwork?
Often yes, but we check first. Existing ducts may work as-is, need targeted fixes, or point us toward a ductless or mixed system. The goal is balanced comfort, not just bolting new equipment onto old ducts.
Do I need ductless mini-splits?
Not always. Mitsubishi has ducted, ductless, and multi-zone options. Some homes want a central ducted system. Others need individual zones, or both. You do not have to pick the equipment type before we talk.
Why does the system need to be designed instead of matched to the old equipment size?
The old system may have been the wrong size, or built for a different layout, insulation level, or use of the house. We figure out what the home needs now so the equipment, airflow, and controls work together instead of repeating the same problem.
What happens after I reach out about a Mitsubishi heat-pump project?
Tell us what you are planning and what is not working. We review the job, decide the next step, and build a recommendation around the actual house, not a generic equipment quote.
