Sheet 03 · Reference

Reference specs

Figures we measure against on site. Where a number comes from a published code or guideline, it is named; where it comes from a nameplate, read your own nameplate.

A multimeter, a wired temperature probe and a fan assembly laid out beside an open service compartment
Every figure on these sheets is one we measure on site, with the instrument that reads it.
Caution

Tolerances on these sheets are our own working service figures, not manufacturer specifications. Where a job touches a gas connection, a dedicated circuit or a sealed refrigeration circuit, it carries its own conditions — epa section 608 certified technicians for refrigerant work, and a licensed contractor for anything structural or electrical in the house itself.

Each service page states which of these figures it is measuring against.
