"I chose Optimize because of the positive feedback and strong recommendations I read in the reviews. I was not disappointed! Matthew, Craig and his work crew could not have been more professional and responsive. They did a great job on the installation of my stand-by generator and the price was very reasonable. I am strongly recommending Optimize to any of my friends or family that need any of the services they provide."

Generator Install FAQs, answered by experts

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.

While standby generators provide essential backup power, they can fail when you need them most due to lack of maintenance, fuel supply issues, dead batteries, electrical problems, or improper installation. To avoid costly failures, professional installation and regular maintenance are crucial. Licensed technicians ensure safety, uphold warranty requirements, comply with regulations, and provide expert servicing.

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.

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

Carbon monoxide emissions aren’t only dangerous to human life, but they also harm our planet. While natural gas generators emit lower levels of CO than other fuel sources, there are still ways to reduce emission levels. For example, shop around for an eco-friendly generator that complies with current emission standards. Also, make sure your generator is serviced regularly to avoid CO buildup.
