How long does a complete generator replacement take?
Most residential standby generator replacements take one to two days. Day one covers removal of the old unit and prep work. Day two involves setting the new generator. We connect fuel lines and electrical. We perform final testing. Weather and permit inspections can extend the timeline slightly.
We can often reuse your existing automatic transfer switch. It must be in good condition. It must be properly rated for the new generator. We test the switch contacts. We verify the amperage rating matches. Older switches may need replacement to work reliably with new units.
We perform a load calculation based on your essential circuits. This includes HVAC, refrigeration, well pump, and lighting. Most homes need between 14kW and 22kW. Larger homes with multiple air conditioning zones or electric heat may require 24kW or higher. This prevents overloading during operation.
