Electric furnaces are a great option for homes without natural gas lines. They are quiet, efficient, and reliable, offering steady heating with minimal maintenance needs. Our technicians size and install your electric furnace to deliver optimal heating comfort all season long.
For homes with natural gas access, a gas furnace provides powerful, efficient heating. We handle gas line connection, venting, safety testing, and complete system setup to ensure your furnace runs safely and efficiently.
We specialize in residential AC installation, ensuring your home stays cool, comfortable, and efficient. Every installation is done by certified professionals using top-quality materials and equipment.
When repairs are no longer cost-effective, our AC replacement services provide a seamless upgrade to a modern system. Enjoy improved cooling power and lower operating costs.

Trusted experts delivering reliable heating & cooling solutions for comfort in every season.
Our licensed technicians calculate your home's exact heating load before recommending any system — so whether you need a gas or electric furnace, it's sized right, vented safely, and installed to code the first time.
You'll get a clear, itemized quote with no pressure to upgrade beyond what your home actually needs. We also walk you through available Washington energy rebates and financing to reduce the upfront cost.
We don't hand the keys back until your furnace is fully tested, running safely, and keeping every room warm — and if anything isn't right after we leave, we make it right. Every installation is backed by manufacturer and workmanship warranties.
If your furnace is over 15 years old, needs frequent repairs, or your energy bills keep climbing, replacement is usually the smarter long-term move. We’ll give you an honest read on this during the consultation instead of pushing a sale either way.
Furnace size depends on your square footage, insulation, and layout, not just a rule of thumb. An undersized furnace struggles to keep up in Seattle’s colder months, while an oversized one cycles on and off too often and wastes energy. We calculate this properly before recommending a system.
Most furnace installs are completed in a single day. If ductwork needs updating alongside it, it can take a bit longer, which we’ll flag upfront.
Yes, depending on the system and your utility provider. We help you understand what rebates and financing options you qualify for before you commit to anything.
Yes. We’re the 2025 Mitsubishi Diamond Contractor of the Year and an American Standard partner. Both furnace brands we install most come with factory-level training behind our crew, which means fewer callbacks and stronger warranty coverage for you.
Our Diamond Rated certification with Mitsubishi is held by only a small number of dealers nationwide. Combined with our American Standard partnership, it means the furnace going into your home is installed by a team the manufacturers themselves have vetted, not just licensed.
At Cloud9 HVAC, we’re proud to bring reliable heating, cooling, and air quality services to homeowners throughout the Greater Seattle area. Whether you’re in Bellevue, Redmond, Bothell, or Kirkland, our certified technicians are ready to deliver comfort and care you can count on backed by integrity, expertise, and local experience.
