JUJCO Heating & Cooling
When a job has already been 'fixed' twice, the senior tech is who we send.
Intermittent lockouts, hydronic ghosts, and dual-fuel controls that fight each other are not first-year problems. The senior technician takes those calls and writes the sequence so it does not bounce back.
They also review commissioning sheets on larger installs before we call the job done.
The second-opinion visits and the systems other shops bounce. If you book this kind of work, this is the seat on the truck that is accountable for it.
