When should repair and replacement be compared?
The decision to replace rather than repair depends on the generator’s condition, frequency of breakdowns, availability of replacement parts, changes in your home’s electrical needs, and the cost of repairs. Age is a factor but not the only one. A professional evaluation can help you weigh the options.
What can be reused?
When replacing a generator, the existing transfer switch, fuel supply line, mounting pad, and electrical conduit may or may not be compatible with a new unit. They must be evaluated by a qualified professional. Never assume that old components can be reused without inspection.
What needs recalculating?
A replacement project should start with a fresh load assessment to confirm the required capacity. Fuel supply (natural gas pipe size or propane tank capacity) may need upgrading. The location must meet the new generator’s clearance requirements and current building codes. Permits and inspections may be required.
How should replacement scope be compared?
When comparing replacement proposals, ask for a written scope that includes removal of the old unit, new equipment, any transfer switch or fuel system modifications, permits and inspections, site restoration, and commissioning (testing and startup). This ensures you are comparing equivalent work.
