Generator Install questions, answered by experts

To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.

Many services include assembling the unit and securing it in the window. Confirm with your provider.

Generator size requirements vary wildly among properties, but typical generator sizes are listed below based on home square footage:

1,000 sq ft: 6–9 kW
1,500 sq ft: 7–10 kW
2,000 sq ft: 10–14kW
2,500 sq ft: 12–16kW
3,000 sq ft: 16–20kW+

Unfortunately, home square footage isn’t always a good indicator of generator size requirements. Instead, you should call in a professional to discuss which items in your home you’d like to run via your generator. They can calculate peak and average consumption for those items and then size your generator appropriately for optimal performance.

When installed and used correctly, generators are safe to use. The most critical generator safety tips to keep in mind are:

Never use a portable generator inside an enclosed space, as the carbon monoxide exhaust it creates is lethal.
Never attempt to connect your generator to your home’s electrical panel independently; hire a professional for this dangerous job.
Never overload your generator by connecting more appliances than for which it’s rated; you can damage your generator and appliances or even cause a fire.

Costs range from $500 to $2,500, depending on generator type and installation complexity.
