Common questions for Generator and Backup Power in Terrell Hills
Whole home generator versus interlock kit - which makes sense?
A whole home standby generator is automatic, runs on natural gas or LP, and powers selected (or all) circuits during an outage. An interlock kit lets a portable generator safely back-feed the panel through a breaker. Whole home is more expensive and hands-off; interlock is cheaper and requires you to start the generator manually.
What size generator do I need?
Generator sizing starts with the loads you want to keep on (HVAC, refrigeration, well pump, medical equipment, lighting). We run the load calculation and recommend a size that matches without oversizing.
Where does a standby generator typically sit?
Outside the home on a concrete pad, away from windows and air intakes per manufacturer and code clearance rules. We confirm the pad location during the site visit.
Does a standby generator need a permit?
Yes - both the electrical interconnect and the gas connection (or fuel storage for LP) typically require permits and inspection. We handle the permit application as part of the project.
How long does a whole home generator install take?
A typical install runs 2-4 days on site once the equipment arrives, plus permit and inspection scheduling. Larger or more complex projects can extend; we confirm the timeline in the written scope.
