"We moved to Vero Beach from New England and purchased a new portable generator that ran sluggishly. I contacted Brian, who came to Vero to trouble shoot the generator and work with the supplier. After assessing and determining the gas and electrical hookups were effective, Brian realized the supplier's natural gas regulator was defective. The supplier sent us a new regulator which Brian came back to Vero to install. Brian also noted that the gas line provided was too small for the unit and contacted the supplier who provided us the proper hose. I can't say enough good things about Brian. The service he provided was excellent, and his commitment to helping us finally get our generator operating properly was noteworthy. Highly Recommended."

"Very professional and personable. Once I made the decision to have the work done they scheduled it for the very next day. They arrived on time, completed all the work, explained everything and left the area cleaner than when they arrived. I definitely will use them for my electrical needs in the future. Love that they guarantee their work for 4 years. Thanks Carlos for the estimate and Zoltran for the service. It was a pleasure working with you."

"The electricians came in and replaced a handful of outlets and a couple of switches in our home and were extremely professional and kind. Walking me through the whole process and asking me questions along the way to make sure I got exactly what I wanted. They were quick, tidy and exceeded my expectations. I couldn’t have asked for a better company to come out and handle my electrical needs. 5/5 would hire them again."

"The electricians did a very clean and efficient job while installing my Tesla wall charger. They knew all about proper sizing for conductors and they used quality materials. The job looks great. They cleaned up after themselves and called back within a week just to verify I was not having any problems. Their customer service is outstanding."

Generator Install questions, answered by experts

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.

Costs range from $500 to $2,500, depending on generator type and installation complexity.

You can expect a diesel generator to last for up to 30,000 hours of use, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two. 

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.

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.
