Common questions for Whole Home Generator Installation in Schertz
How big a generator do I need?
Depends on what you want to back up. Whole-home backup typically needs 22-26 kW for a 2,500-3,500 sq ft home with central AC. Essential-circuit backup runs 12-18 kW for refrigeration, key lighting, well pump, and partial HVAC. We run the actual load calc.
How much does a whole-home generator cost installed?
Total install cost includes the generator, the automatic transfer switch, the concrete pad, the gas line work, the electrical permit, and labor. We quote in writing after the load calc and site walk.
Will the generator run on natural gas or propane?
Most modern standby generators run on either, with a fuel selector at install. Natural gas is preferred when available. LP requires a tank sized to the runtime expectation.
How loud is a whole-home generator?
Modern Generac and Kohler air-cooled units run around 65-70 dB at 23 feet, similar to an outdoor AC condenser. Liquid-cooled units (larger) are quieter. Setback distance from neighbor windows is part of the placement plan.
How long does the install take?
Total project from quote to commissioning is typically 4-8 weeks, depending on permit speed, gas line scheduling, and pad pour time. The actual on-site install is 2-3 days.
