Common Questions

Residential Electrical FAQs

Common questions from Triangle homeowners about residential electrical services. Don’t see yours? Call us directly — we’re happy to help.
How long does a full generator replacement take?
Most replacements take one to two days depending on your existing setup. We remove the old unit and prepare the pad if needed. We set the new generator and connect fuel lines. We wire the transfer switch and test the system. Complex electrical panel upgrades or fuel line modifications can add time. We schedule inspections before you need them.
It depends on the age and amperage rating. If your current switch is properly sized and in good condition, we can often reuse it. Older mechanical switches may not communicate with newer digital generators. We test all existing components. We recommend upgrades only when necessary for safety or functionality.
Possibly. We perform a load calculation based on your current electrical service and essential circuits. If you added central air conditioning, a pool, or other major appliances since your original installation, your power requirements have increased. We size generators to handle your actual needs, not just match the old unit.
We disconnect it properly and drain all fluids. We haul it away as part of our service. We dispose of generators according to local regulations since they contain oil, coolant, and other materials that require proper handling. The removal is included in our replacement pricing with no extra fees.
We install generators configured for your existing fuel type. If you are switching from propane to natural gas or the reverse, we coordinate with licensed gas fitters to modify your supply lines. Natural gas provides unlimited runtime but requires utility service. Propane needs tank refills but works anywhere.

New generators include manufacturer warranties ranging from two to ten years depending on the model. Our installation work is guaranteed for two years. This covers all electrical connections, transfer switch wiring, and startup programming. Manufacturer warranties handle equipment defects while our guarantee protects your investment in proper installation.
