Q: Does it power the whole house?
A: It depends on the size (kW rating) you choose. We can configure the system two ways:
Whole-Home Solution: Powers everything simultaneously, including central A/C. Requires 22kW-48kW depending on your home size.
Load-Managed Solution: Powers critical circuits (lights, refrigerator, some outlets, garage door) and uses a “load shed” module to cycle heavy loads like A/C. Requires 14kW-20kW.
We perform a Load Calculation at your home to determine which approach fits your needs and budget.
Q: Does it run on Natural Gas or Propane?
A: Generac units can run on either fuel source. Most Houston-area homes use Natural Gas because it’s available from CenterPoint Energy’s underground infrastructure (endless supply). Rural properties typically use Propane from a large tank (500+ gallons).
The advantage of natural gas is you never run out. The advantage of propane is slightly higher efficiency and independence from utility infrastructure.
Q: Is it loud?
A: Modern Generac units are significantly quieter than portable generators:
Portable Generator: 70-90 dB (sounds like a lawn mower)
Standby Generator: 60-65 dB (sounds like a normal conversation)
During the weekly exercise, they operate in Quiet-Test mode at reduced RPM, making them barely noticeable. Under full load during an outage, they’re about as loud as your outdoor AC condenser unit.
Q: How long does it run before needing service?
A: We recommend professional service every 200 hours of run time or annually, whichever comes first. Most homeowners never hit 200 hours unless they experience a major multi-day outage.
During the annual service, we change the oil, replace the air filter, check the spark plugs, test the battery, and verify the transfer switch operates correctly.
Q: What happens if the generator fails during an outage?
A: This is where our Mobile Warehouse model proves its value. We dispatch a fully stocked van with replacement parts (batteries, control boards, contactors) to restore your power during the storm. Most generator companies don’t offer emergency service during outages because they don’t stock parts.
Q: Can you take over maintenance on a generator another company installed?
A: Yes. As Authorized Generac Dealers, we can service any Generac unit regardless of who installed it. Many customers come to us after their original installer went out of business or stopped responding to service calls.
Q: Do I need a permit?
A: Yes. Generator installations require electrical and gas permits from your city. We handle all permitting and coordinate the required inspections. This is why we recommend using a licensed contractor rather than attempting DIY installation.
