"Tom Mullaney and his team at Wire Works Inc. are top notch. Very professional, responsive, and reasonably priced. Wire Works most recently assisted as with all our electrical needs for a complete kitchen remodel - new outlets, switches, can lights, pendant lights, stove hookup, etc. When the team wasn't able to complete all tasks on the scheduled day for our rough electrical, they found a way to squeeze us back into the schedule so our kitchen remodel could stay on schedule. Tom Mullaney is one of the nicest people you'll meet, and provides an outstanding service. I won't use anyone else."

"Jarod did an excellent job. Completed an EV outlet install in a few hours. He came out to do an estimate and had all the supplies he needed in his truck and hired him on the spot. Fair pricing and very neat a clean work. EV outlet works like a charm. Will definitely hire him to do future work at my house."

"I can not began to express how happy my hubby and I were with the service provided by Dan. He was very professional, timely, and cost effective. When he took our generator in for repair, he actually left a generator just in case the power went out again. This was greatly appreciated as we have a sump pump and were just getting over cleaning our basement due to power outage which caused the use of our sump pump"

Generator Install questions, answered by experts

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.

A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the total wattage of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.

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.

It’s usually better to repair your generator if it isn’t working properly, as it will typically be much more affordable and should yield similar results. Generator repairs cost around $300 on average, while installing a new whole-house generator costs around $5,000 on average. The only exception is if you know your generator is reaching the end of its useful life, usually between 30 and 40 years. If you have an older generator, you could face multiple repairs in the coming years, which might mean that a full replacement will be more cost-effective over time.

DIY is possible for basic setups. Professional installation ensures safe and proper electrical connections.
