"Quinn was professional and courteous. In addition to the EV charger installation, he also installed 2 new circuits with breakers and new conduit. All the work looked amazing and he and his associate cleaned up everything when they were done. Couldn’t have been happier with the work done. Would highly recommend Quality Electric."

"Steve Cavanee Electric installed a power transfer unit at my house to transfer power from the grid to generator power. They did excellent work, showed on time and did the installation at a fair and reasonable price. They provided follow-up communication with directions as well. I will be using them again as the need arises."

"Very happy with the work completed by Bill (owner), Josh and Pat. Bill always responds promptly to text and calls and explains things clearly. Provided free quote and visited the house to confirm quote. Josh and Pat arrived on time and worked neatly. Josh was able to avoid trenching thru the ceiling even though attic space was limited. They even put back closet shelf that had to be removed to access attic. Josh and Pat even came by another day to help install a remote that I did not have on the day of installation."

"The folks a M&ES CONSTRUCTION ENGINEERING INC. Did a great job with my project. They renovated my garage, they drywalled and painted it, also gave me a beautiful epoxy floor thats easy to clean and a treat for the eyes. I also had them remove my old brick gas fireplace and build a tile faced electric fireplace with an insert for my Television. My TV fits perfectly and it looks amazing. Workmanship is top notch, they are transparent, punctual, and very communicative. Truly the best contractors I’ve worked with."

Generator Install questions, answered by experts

The average cost to install a home generator is $5,200, but total costs can range from $500 to $18,000 or more. The final price depends on several factors, including the generator's size, type, brand, fuel source, and the cost of labor and assembly. The generator's size is the most significant cost factor, as units that can power larger homes with higher energy demands cost more.

Cost breakdowns by generator type are typically as follows:

  • Portable or Emergency Backup Generators (1kW–7.5kW): $500–$2,000

  • Partial-Home Generators (9kW–20kW): $2,000–$6,500

  • Whole-House Generators (22kW–48kW): $5,000–$18,000

To ensure you get the right size unit for your needs without overpaying, consider hiring an electrician to calculate the electrical load of your essential appliances. It is also recommended to get at least three quotes from qualified installers to find the best fit for your budget.

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.

Yes, natural gas generators can work without electricity. Natural gas generators are a common type of backup or whole-house generator that operates when the electrical grid isn’t working. The trick is using a transfer switch (which usually needs to be installed with the generator) that safely switches the home electrical system from the power grid to generator power when needed.

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.

A home that is 2,500 square feet will likely need a 20kW to 25kW generator. Consult your local generator installer to confirm the generator size needed to power your home before purchasing a new one. Be sure to consider how much power your necessary devices need to run.
