"Phoenix electrical is owned by Paul, a master electrician, who does the initial consultation to figure out a quote, he is very direct and honest but easy to talk to and work with. Their customer service is excellent, they kept me well informed throughout the process and were very friendly and accommodating. Pheonixs quote was fair without question, his crew had a tough job installing a generator transfer switch kit set up, I live in a house built in the late 80s, so, the electrical system is a bit older and they ran into issues but they worked non stop and persevered through the challenges, found solutions, and completed the job as promised. Without question, I recommend Phoenix Electrical, and I will certainly seek them out first for any future electrical work. Thank you."

"When I made the request on Angi's List, Gonelectrical called me within seconds. We talked about installing a whole-home surge protector. I traded some photos of my panels and received a quote over the phone. The job was scheduled for the next day. They showed up promptly and completed the work professionally. They explained what they did and showed me exactly what was done. I would recommend this company for similar work."

"What i noticed first off was the peace of mind. Rightway Electric assured me they would take care of the problem and they did!! Expertise in their craft Hospitality, timely, detailed Customer satisfaction Awesome team work! I could go on. I am totally satisfied with this company. They saw me thru several days without electricity. It was disconnected on a Monday @7:30a and re- connected Thursday between 7-9a. During this time Right way Electric, furnished generators, and left a team member to be here when the electric company showed up. A phenominal, young man, expert in his knowledge. Courteous and respectful young man. If I could give more stars, i would."

Generator Install questions, answered by experts

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.

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.

The cost to install a whole-house generator averages $5,200, with a typical price range of $1,500 to $8,900. However, total costs can vary from $400 for a small portable unit to over $18,000 for a large-capacity system. The most significant cost factor is the generator's size and capacity, but other variables include the brand, fuel type, and labor for assembly and installation.

Generator costs can be broken down by type:

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

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

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

To avoid paying for more power than you need, consider hiring an electrician to calculate the electrical load for your essential appliances. It is also recommended to get at least three quotes to find the best deal for your specific needs and budget.

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.

A portable generator can supply power to selected appliances and circuits in a home, but it's generally not designed to handle the entire household's electrical needs simultaneously. Portable generators have limited wattage capacity, so they are only designed to power essential devices and electronics temporarily until local power is restored. If your power needs outweigh the capabilities of a portable generator, consider installing a whole-home generator instead.
