WA contractor registration
Black Book Home Services is registered with Washington Labor & Industries under contractor registration BLACKBH744PA.
CREDENTIALS & STANDARDS
Professional work should be easy to verify.
Black Book Home Services is a Washington registered contractor, bonded and insured, with EPA 608 Universal certification supporting HVAC refrigerant work.
THE BASICS
Credentials that match the work.
Credentials matter, but they are only the starting point. The work still has to be diagnosed carefully, completed correctly and tested before it is called finished.
Bonded & insured
Black Book maintains contractor bonding and commercial liability insurance. Documentation can be provided when a project, supplier or customer requires it.
EPA 608 Universal
EPA 608 Universal certification supports service work involving regulated refrigerants and the refrigerant side of HVAC equipment.
Scope matters
Work is performed within the scope of applicable registration, certification, permits and code requirements. Separate specialty-trade work is not misrepresented as general mechanical repair.
Documented findings
Service recommendations are built around the condition found, the measurements taken and what the customer needs to know next.
Test after repair
Approved work is operated and checked after completion so the repair is verified against the original complaint.
THE BLACK BOOK STANDARD
“A credential gets you through the door. The quality of the diagnosis and the workmanship are what should earn the customer’s trust.”
That is why the service library explains the actual diagnostic process instead of relying on badges alone.
