Permits, utility fees and applicable sales tax are additional. Prices subject to change.
Commercial services
KJSYSTEMS bids and runs electrical, plumbing and mechanical scope on commercial and industrial projects: tenant fit-outs, lease-space shells, equipment tie-ins and building-system coordination. One sub covering multiple trades means fewer gaps between scopes and fewer change orders where they meet.
Lease-space build-outs coordinated across electrical, plumbing and mechanical.
Service, panels, feeders and equipment connections.
RTU work, duct systems and controls tie-ins.
Duct smoke detection and shutdown interlocks with the fire alarm system.
Equipment power, controls and utility connections.
Generators and transfer equipment for critical loads.

03
One scope, one schedule, and one company accountable for the result.
Before you call anyone
These take about ten minutes and they will save you money, with us or with whoever you hire.
Usually where the water line enters the house: a basement wall, a crawlspace, or near the water heater. Turn it once so you know it moves. Photograph it and note which way closes.
A burst supply line puts out several gallons a minute. The difference between knowing and hunting is a wet floor versus a claim.
Open the panel door (not the cover) and check the main breaker’s amperage. Write down what each circuit actually feeds instead of what the faded label claims.
A breaker that trips more than once is telling you something. Knowing the panel’s size decides whether a hot tub, EV charger, or A/C is even possible.
It’s at the furnace or behind a return grille. The size is printed on the frame’s edge. Put it in your phone and check it monthly during heavy heating and cooling.
A clogged filter starves the blower. It’s the cheapest cause of weak airflow, high bills, and the failures we get called out for.
