"Had two EV charging stations installed at my home in Middletown and I’m very happy with the work. Everything came out super clean and professional. He explained the entire process clearly and walked me through everything step by step. I got a few prices before hiring him and he was also the most affordable. Great work, great communication and fair pricing. I would definitely recommend Elite Electric Solutions. Definitely getting him back in for some recessed lighting and routing some wires for my audio and camera system. Jorge is definitely my electric from now on!"

Jim used excellent communication skills and computer technology to design,explain, and show pictures of the finished product.

Customers say: Quick response

"Woke up with no heat! Right before Christmas! Harris responded instantly and sent out someone to check the problem. Due to incorrect installation, rain had gotten into the improperly sealed roof vents, which in turned fried the transformer, inducer and circuit board. They were at my place bright and early the next morning installing a brand new furnace, more efficient and quieter, with a 10 year warranty. Arranged financing and were finished by 3pm. Everyone from my first phone call to the last service tech was professional, polite, knowledgeable and all around pleasant and really nice people. They will be my go to for heating, AC, plumbing and electrical from here on in. Glad I found them!"

Generator Install questions, answered by experts

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window. 

Potential benefits of using a natural gas generator include reducing your carbon footprint, lower likelihood of carbon monoxide exposure, budget-friendly operating costs, and low-maintenance, continuous fuel supply. Some possible drawbacks, though, include higher initial installation costs, dependency on a natural gas supply, and installation complexity. Keep in mind that pros and cons will vary based on the type and brand of natural gas 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.

If you’re deciding between a solar battery versus a generator for the best backup power solution, you can take a few factors into consideration. Solar batteries are quiet while generators can be quite loud. Generators have a lower up-front cost, but they require fuel and ongoing maintenance while solar batteries are more expensive but don’t have many ongoing costs.

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.
