"I was impressed how quickly they contacted me to discuss my project, within in minutes I had someone schedule to come and look at the site and discuss what we needed. One week later there were at my house replacing the generator. The tech arrives on time and provide on-going update on the process. They left the project site so clean you would never know I have any work done in the area. I would highly recommend."

"Alex and Luis just finished doing a furnace service and duct cleaning on my condo. They did a fabulous job fixed and cleaned everything even came back and vacuumed some smuts left from them cleaning a high ceiling vent. Would highly recommend this business especially Alex and Luis. No heavy handed sales tactics either which was nice. Thanks again!"

"Breaker Brothers Electric may be a fairly new company, but I urge you to take a chance with them. I did and couldn't be happier with their work. Matt and John are both great to work with and their bid was very fair and beat the competition. They replaced our old breaker box and installed a car charger for us. The work was great, the communication was clear and timely, and the guys were trustworthy and friendly. The project was done well and on time. Next time I have any electrical needs, I'll call them directly. I was very impressed with Breaker Brothers Electric!"

"I needed an outlet added to the inside of our fireplace for the new gas fireplace fan. Jason showed up on time and got started on it even before the fireplace installation team showed up. He was courteous and gracious about having to wait. Once they arrived, he worked closely with the other team and did an excellent job on installing the outlet. I will definitely hire them again."

Generator Install questions, 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.

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.

With proper maintenance, a whole-house generator can last between 20 and 40 years. The specific lifespan depends on how often and for how long the generator is used, and some models may have their life expectancy rated in hours of operation. To maximize its lifespan, expect to spend around $150 to $300 per year for annual maintenance checks from a qualified technician. During these checks, a technician will inspect the engine filter, starting mechanism, fuel, lubrication, and coolant levels. Consulting your installer and choosing a low-impact fuel like natural gas or diesel can also help ensure your generator lasts as long as possible.

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.

Yes. You can connect your home back-up battery to a generator with its designated charger. Be sure that the output of the generator matches the input requirements for the battery for best results.
