Frequently Asked Questions

What's the difference between a ductless heat pump and a regular heat pump?

A ductless system, also called a mini split, doesn’t need existing ductwork to install. It uses an outdoor unit connected to one or more indoor wall units. This makes it a common choice for additions, ADUs, and older Seattle homes where adding ducts would be expensive or impractical.

Yes. Most ductless systems we install handle both, which is part of why they’ve become popular in Seattle. One system covers your winter heating and summer cooling instead of running two separate units.

That depends on how many rooms or zones you want to control separately. We assess your layout and recommend a setup that covers your space without over installing units you don’t need.

They’re generally efficient compared to older electric heating, especially newer Mitsubishi Hyper Heat models built for colder climates like ours. Actual running cost depends on your home’s insulation and how you use the system, which we’re happy to talk through.

Ductless heat pumps are precision equipment, and Diamond status means our team completed Mitsubishi’s highest level of factory training. Cloud9 was named the 2025 Mitsubishi Diamond Contractor of the Year, which also unlocks extended manufacturer warranties for our customers.

Yes, that’s actually our specialty. As a Diamond Contractor, our installers are factory-trained on the Hyper Heat lineup built for colder climates, which is why so many Seattle homeowners come to us specifically for ductless installs.
