Common questions
Do I need a licensed electrician for a generator?
Yes for non-exempt electrical work in Texas. A standby generator, transfer switch, inlet, or interlock should be installed through a licensed electrical contractor. That protects the house and the utility workers.
What size generator do I need?
It depends on what you want to run. AC, refrigerator, freezer, lights, medical equipment, well pump, and cooking loads all matter. The installer does a load calculation instead of guessing.
Can I use a portable generator safely?
Yes, with the right setup. Use an inlet and interlock or a proper transfer switch. Never backfeed through a dryer outlet, and never run the generator in a garage or near windows.
Can you install before hurricane season?
That is the best time. Once storms enter the Gulf, generator inventory, electricians, gas plumbers, and permit offices all get backed up. Spring and early summer scheduling is much easier.
Does a standby generator need natural gas?
Most run on natural gas or propane. The installer checks meter capacity, gas-line length, regulator setup, and placement. Some homes need gas work before the generator can run correctly.
Where can the generator sit?
Placement has clearance rules for windows, doors, vents, property lines, and flood-prone areas. On Padre Island and bayfront lots, wind, salt air, and storm surge exposure also matter.
Do generators need maintenance?
Yes. Batteries, oil, filters, spark plugs, exercise cycles, and error codes need regular checks. A generator that sits all year without service may fail exactly when the power goes out.
Coastal Bend seasons
Spring (March - May)
Best window for sizing, permitting, and install before hurricane demand spikes.
Summer (June - August)
Outage planning becomes urgent. Heat also makes AC load management important when sizing the generator.
Fall (September - November)
Named storms can create long equipment waits. Maintenance checks are common before late-season Gulf activity.
Winter (December - February)
Good season for planned installs, replacements, and service because storm-demand pressure is lower.
