When you're building a custom home, every detail matters—from flooring and finishes to layout and lighting. But one of the most overlooked (and most important) systems? Your HVAC.
At GreenFlow Heating & Cooling, we specialize in designing HVAC systems that match the layout, style, and performance goals of your one-of-a-kind home. Because cookie-cutter ductwork doesn’t belong in a custom build.

Why HVAC Isn’t One-Size-Fits-All
Most spec homes use pre-packaged HVAC designs. But your custom home likely has unique ceiling heights, window placements, room sizes, and zoning requirements—all of which directly impact how heating and cooling systems should be designed.
An improperly sized or installed system can lead to:
Inconsistent comfort from room to room
Excess humidity or poor air quality
Increased energy costs
Long-term wear and tear on the equipment
We believe every custom build deserves a clean, efficient system that works with your home—not against it.
What We Consider in a Custom HVAC Design
We start by working directly with your builder or architect to make sure the HVAC plan matches the structure, aesthetics, and efficiency goals of your home.
Here’s what goes into our process:
Load calculations for proper sizing
Duct layout or ductless system planning
Vent placement that doesn’t interfere with lighting or design
Energy efficiency goals and rebate opportunities
Room-by-room zoning based on usage
Filtration and IAQ solutions from day one
Whether you’re going all-electric, using smart thermostats, or incorporating solar, we’ll make sure your HVAC system complements the entire build.
Why Ductless and Zoned Systems Are Game-Changers
For many custom homes, we recommend ductless mini-splits or hybrid systems with multiple zones. These options allow for:
Individual temperature control in different areas of the home
Less ductwork, which preserves ceiling space
Better energy efficiency and quieter operation
Flexibility in open or multi-use floor plans
You get total control—and serious performance—without sacrificing aesthetics.
Final Thoughts from the Field
We’ve partnered with homeowners and builders throughout the Pacific Northwest to deliver HVAC solutions that match the integrity and design of each unique home.
If you're planning a custom build or major remodel, involve HVAC early. It saves headaches down the road and ensures your system enhances the comfort and value of your home.
