What's wrong at the house?
Say it the way you would on the phone. The office sends the right trade, whichever of the three it is.
- 01 Plumbing
Water is leaking
If you can safely reach the shutoff, close it, and keep clear of wet electrical equipment. Call to describe where the water is coming from and confirm the next visit.
- 02 Water heaters
No hot water
Tell the office whether the unit is gas or electric and whether there is water around it. A visit starts with diagnosis, then a written repair or replacement option.
- 03 Air conditioning
The AC isn't cooling
Note whether air is coming from the vents and when the trouble began. Call to arrange an AC diagnosis and confirm any diagnostic fee before dispatch.
- 04 Electrical
The breaker keeps tripping
Leave the circuit off and do not keep resetting it. Call for an electrical inspection. A burning smell, smoke or immediate danger needs emergency services: call 911.
Nothing goes in until you approve the scope.
Sample: the van carries the common fittings, so many repairs can finish in one visit.
Licensed for all three trades, in writing.
Plain figures you can check, not badges. The number goes on the van, on this page and on every written scope.

- Inspect and explain
The tech looks at the problem, then explains the options in plain words.
- Approve, then work
