Keep Power When You Need It

Power outages strike without warning. A backup generator keeps lights on. It powers your fridge. It protects critical systems. You need a system that works the moment you lose utility power.

Air-Tro installs and services backup generators for homes and businesses. We guide you through choosing a unit that fits your living space and budget.

What Size Generator Do I Need to Backup My House?

Generator size depends on your power needs. Essential circuits like lighting, refrigerator, and sump pump draw less than 10 kW. A whole-house generator that runs AC and all circuits may need 20–25 kW.

We calculate total wattage based on your appliances and circuits. Then we recommend a generator with enough capacity and a safety margin to keep you running smoothly.

Finding the Right Generator for Your Home

Generators come in natural gas or propane models. Whole-house units often start at 20 kW; essential-power generators start at 10 kW. We factor in:

  • Your home’s size and wiring capacity
  • The critical appliances and systems you want to keep online
  • Fuel availability and cost considerations

We help you pick a generator that matches your needs without overspending.

Automatic Transfer and Monitoring

Automatic transfer switches sense power loss and start the generator in seconds. They shift your home’s circuits to backup power without any manual steps. Optional remote monitoring lets you check generator status from a phone or computer. You receive alerts before service is due. That adds confidence that your system will work when you need it.

Installation and Ongoing Care

Installation covers permits. It covers fuel connections. It covers electrical tie‑ins. That makes your generator ready when power goes out. We visit twice a year for inspections. We change oil. We replace filters. We test batteries. We check for cold-weather readiness. This routine service prevents surprises. It keeps your system running.
