Why Conroe Homes Lose Power First During Hurricanes & Derechos

Unlike underground inner-loop feeders, Montgomery County relies on long overhead Entergy Texas and CenterPoint radial lines threading through 80-ft loblolly pines. During May 2024's Derecho and July 2024's Hurricane Beryl, over 85% of Conroe feeders went dark for 4 to 9 days.

❓ Conroe Standby Generator Installation & Service FAQ (Verified Entergy / CenterPoint Answers)
Updated Oct 2026 · Montgomery County

1. How much does a whole-home Generac or Kohler generator cost installed in Conroe, TX? (generac conroe tx)

In Conroe and Lake Conroe, a complete turnkey 22kW to 26kW air-cooled whole-home standby generator (Generac Guardian® or Kohler RCA) averages $10,450 to $14,600 installed when your natural gas meter and main electric breaker panel are on the same side of the house. If the gas line or electrical conduit must be trenched 50 to 90 feet around the home to the opposite side, or if your home has dual 200A panels (400A service), turnkey pricing typically ranges from $12,900 to $16,500. Liquid-cooled 30kW–48kW estate systems run $21,500 to $32,000+.

2. Will a 24kW or 26kW generator run two air conditioners during a summer Conroe outage? (conroe generator)

Yes — when wired with Smart AC Load Management modules and compressor soft-start kits. While a 4-ton AC only draws ~18.5 amps while running, it spikes to 105–120 Locked-Rotor Amps (LRA) for a split second at startup. Our electricians wire your thermostats through the Smart ATS so the two AC condensers never start at the exact same second, and soft-starts cut startup inrush by up to 68%, allowing a 24kW or 26kW unit to cool your entire 3,500 sq ft home effortlessly.

3. Do I need a CenterPoint Energy gas meter upgrade for a standby generator in Conroe?

Often, yes. Standard residential 250 CFH natural gas meters operating at 4-ounce pressure (7" WC) are sized only for a furnace, water heater, and stove. A 24kW–26kW standby generator adds 278,000 to 312,000 BTU/hr of gas demand at full load. We calculate your total connected BTU load and coordinate directly with CenterPoint Energy (or Universal Natural Gas) to upgrade your meter bar to an elevated 2-PSI meter with a dedicated step-down regulator at the generator so your engine never starves during a hurricane.

4. Do you also offer generator repair and annual maintenance in Conroe, TX? (generator repair conroe tx)

Yes. Air-cooled standby generators run at 3,600 RPM in 95°F+ Montgomery County heat and require an oil & filter change every 24–48 hours of continuous storm runtime (plus annual synthetic oil, spark plug, air filter, battery load testing, and valve lash checks). We service and repair existing Generac, Kohler, and Cummins units across Conroe, Lake Conroe, Willis, and The Woodlands — even if another company originally installed your system.
