Case study · Colorado HVAC

Built inside a real trade shop.

Wrench Office’s back-office model was built and run first inside Uncle Johnny’s Heating & Air, a Colorado HVAC shop.

The work behind the model.

Uncle Johnny’s Heating & Air agreed to share its workflow. It was the starting point for Wrench Office:

Estimate follow-up texts on days 2, 5 and 10.
Housecall Pro and price-book cleanup.
Review requests and reply support.
Invoice follow-up and past-due reminders.
A weekly results report emailed to the owner.

Workflow, not a results claim. These are the tasks described in the source plans and project brief. This case study does not claim that a specific amount of money was recovered or a specific number of jobs was won.

Results coming soon.

Recovered payments attributable to follow-up: Results coming soon

Additional estimates won after follow-up: Results coming soon

Measurement period: Results coming soon

No customer records, customer names, testimonials, logo or mascot are used here. Any public results or clips need evidence and approval before publication.

A Colorado starting point. A national service.

Wrench Office serves small US HVAC, plumbing, electrical and roofing shops. The case study is one shop’s workflow, not a promise of results for yours.

We do the work in your tools.

Your monthly fee pays for administrative services we perform, not access to our internal tools. You keep and pay for your own Housecall Pro, Jobber or other shop tools. We use only the staff access you authorize. We email reports about the work completed for your shop.
