Is Dnd Services the right fit?
Based on what Dnd Services lists with AirProHQ: services offered are HVAC contractor. We have no record of them advertising 24/7 emergency service — call ahead to confirm hours for anything urgent. Their Washington contractor licence is verified and active as of our last check. For anything not covered here — such as whether they specifically serve commercial or multi-unit properties — that's worth confirming directly with Dnd Services before you book, or compare other Redmond contractors first.

How to check this licence yourself
Don't take our word for it — Washington publishes this for free, and it takes about a minute:
- Search for Washington State Department of Labor & Industries's own public contractor licence lookup — every state runs one.
- Search licence number DNDSES*963NP, or the business name Dnd Services.
- Check the status reads active and the expiry is in the future — ours shows 2028-10-17.
- Ask to see proof of liability insurance too. State licensing does not cover that, and we cannot verify it.
A licence means the state has certified the holder to do this work. It is not a guarantee of workmanship, price or availability — see our contractor hiring checklist for what else to ask.
