Honest answers about the air you breathe indoors.
Union Harbor HVAC Finishes works on heating, cooling and indoor air for homes and businesses from SW 336th Street in Federal Way.
Start with what you already have.
Smoke seasons and hotter summers have made indoor air a real worry here, and a lot of products are sold on that worry. We start the other way round: what can your existing system do, with the right filter and settings? Often that's most of the answer. When it isn't, we'll explain the next step and what it costs, in writing.
Five things you can hold us to.
- What you have first
- We look at your system before suggesting anything new.
- No purity claims
- No "99.9%" promises or miracle devices.
- Written prices
- Before any billable work.
- Ventilation respected
- Smoke-day plans for businesses never just switch it off.
- Both halves
- Homes and businesses get the same care.
Half the work
Houses and townhomes across Federal Way, Auburn, Kent and Des Moines.

What "Finishes" does and doesn't mean.
Union Harbor HVAC Finishes is a heating, cooling and indoor-air contractor. "Finishes" is part of the business name, not a second trade — we don't do painting, coatings or finishing work.
