The entire mechanical team was professional, from Sean helping us find the right replacement boiler, to Nate and Zander who performed the installation were kind, respectful, timely and so helpful. I would absolutely use them again for future projects and recommend them f to my friends and family."

Generator Install questions, answered by experts

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

The typical cost of a home generator is around $5,000, but prices range from $400 up to $13,000, depending on a few factors. The most significant cost factor is the generator size, as larger generators that can support more square footage usually cost more. You can install an emergency backup generator for between $500 and $2,000 or a partial-home generator for between $2,000 and $6,500. Whole-home generators usually total between $5,000 and $13,000, with some models climbing as high as $18,000.

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.

When choosing the right size generator for your needs, consider a few items to help calculate the wattage you’ll need. Start by determining which household items and appliances you want to power, and then add the wattages together. Check out the wattage of these essential appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 watts

Running home appliances like these requires a partial or whole-house generator. A portable generator may be enough to power your home if you only plan to keep a refrigerator and freezer running. 

Costs depend on generator type, labor, and additional wiring or transfer switch requirements.
