An oversized or undersized system installed without a real load calculation will short-cycle or never keep up, no matter how good the equipment is. We start with actual measurements, not a tonnage guess.
Many comfort issues go back to sizing decisions made years earlier. Assessment comes before equipment selection, every time.
Standards we hold on every job.
We walk the property room by room measuring insulation and window exposure before a single equipment number gets written down.
The paperwork gets filed and the work meets current Vashon, WA building code, not a shortcut version.
Our labor carries its own written guarantee independent of what the manufacturer promises on parts.
We check what's already running through the walls before assuming it'll work fine with new equipment.
We show you the thermostat, filter location, and maintenance schedule before we leave, not just hand you a manual.
From assessment to final inspection.
A full Manual J assessment covers all four.
Recommendations are based on your actual load numbers, not the highest-margin unit.
We test and correct ductwork.
New equipment often has different requirements — we verify capacity before install day.
The install covers everything through startup testing.
Documented and code-compliant, useful if you sell the property.
What to expect.
We book an in-home visit — sizing can't be done accurately by phone.
Assessment equipment arrives on-site.
Options based on actual data.
We install, commission, and back the labor with a written warranty.
Recent reviews from full system installs.
Adding a home addition meant our old system couldn't cover the extra square footage. They recalculated the whole house load instead of just adding a mini-split and hoping.
— O.Achterberg, homeowner
Historic home with plaster walls that make duct modifications tricky. They found routes through existing chases instead of cutting into walls we wanted to preserve.
— I. Constantinou, homeowner
Home office recording setup needed a quiet system, and they specifically sized and placed equipment to keep noise down in that room.
— U. Nnamdi, remote worker
Multi-generational household with very different temperature preferences upstairs versus down. Proper zoning during install solved an argument that had been going on for years.
— E. Malinowski, homeowner
Basement apartment conversion needed its own independent system separate from the main house, and they designed the whole thing around that specific requirement instead of trying to tie into the existing ductwork.
— F. Castellucci, homeowner
