Backup standby generators
Most HVAC contractors in The Woodlands do not install generators. AOT Mechanical does. For homes, businesses, and industrial facilities, since 2009.

Southeast Texas gets summer storms that knock out distribution lines for days and the occasional winter event that overloads the grid entirely. A correctly sized standby generator starts within seconds of a power drop and runs unattended for as long as the fuel holds.
Natural gas from the utility main does not run out the way a propane tank does, which is why most standby installations in The Woodlands connect to the gas line.
Every circuit in the panel is listed, critical loads identified, and surge requirements calculated. The generator is sized to handle what matters with headroom, not guessed from square footage.
Concrete pad, gas line connection, automatic transfer switch, and load management. The transfer switch brings circuits online in stages so the generator never sees every motor start at once.
Whole-home or critical-load standby units for single-family homes. Keep the AC, refrigerator, lights, and medical equipment running through a multi-day outage.
Commercial standby power for offices, retail, restaurants, and warehouses. Sized for compressors, lighting, POS systems, and refrigeration.
Larger installations for manufacturing, data rooms, and facilities where downtime costs more than the equipment.
Scheduled maintenance keeps a generator ready for the outage it was bought for. Oil changes, load testing, transfer switch exercise, and battery checks.
A generator that is too small will not keep the AC running when the compressor surges at startup. A generator that is too large wastes fuel and money on capacity that never gets used. The right answer comes from a load calculation, not a catalog.
Running watts and starting watts are different numbers. A central AC system pulls 3,000 to 5,000 watts running but surges to two or three times that for a few seconds while the compressor starts. If two motor loads start at the same time, even a correctly rated generator can trip. That is why proper installations include a load management system that brings circuits online in stages.
AOT Mechanical sizes from the actual nameplates and meter readings on the equipment in the building, not from an online calculator. Call (281) 883-9972 and the crew will walk the panel with you.
The first step is the load calculation, not the brand catalog. Consumer and commercial financing available.
