Why DFW homeowners consider generators
North Texas gets extreme heat, strong storms, and occasional winter weather. A generator can protect comfort, refrigerators, medical equipment, remote work, security systems, and basic home operations during outages.
What size generator do you need?
Generator sizing depends on what you want powered: the whole home, just essentials, or selected circuits like fridge, lights, Wi-Fi, and HVAC. Bigger is not always smarter if the gas and electrical setup cannot support it.
Big cost factors
- Generator size in kilowatts
- Natural gas vs propane
- Distance from gas meter and electrical panel
- Transfer switch type
- Concrete pad or generator base
- Permit, inspection, and utility requirements
- Whether HVAC is included in backup circuits
