## Hvac/Rfrg contractors in Washington

777 registrations carry the Hvac/Rfrg specialty — the 20th most common of the 68 trades with a page here. 445 are active today.

Of the 777 registrations in the Hvac/Rfrg specialty, **445**
are active. Among those active ones, **9** have no
current surety bond in L&I's file and **444** have
no current liability policy — the two things RCW 18.27 requires and that L&I
tells you to check before signing.

**27** are suspended right now, and
**183** have been suspended at some point without
being suspended today. The file records the date of a suspension, never its
reason. [What the statuses mean](/status.md).
