"My solar inverter stopped working in my existing solar system, and since my original installer went out of business, I had a hard time finding someone to replace the inverter provided by SolarEdge. It was a small job, and most large companies weren’t interested, while those willing to help were booked out for at least a couple of months. I contacted Justin, and he replaced the inverter within just a few days. He was very friendly, efficient, and offered a very reasonable price. Justin was also extremely knowledgeable, explained everything clearly, and kept me updated throughout the process. He arrived on time, completed the work neatly, and made sure the system was running perfectly before leaving. Overall, his professionalism, honesty, and dedication to customer satisfaction made the whole experience stress-free and smooth."

"FM Generator is efficient and performs high quality work. Great customer service responsiveness. Despite the virus, they moved ahead quickly with the project. The only hold-ups were the inspections. System works great. Well worth the money."

"Jason and his team installed recessed lighting throughout my home and rewired my kitchen during a renovation. They were on time and worked efficiently. Cleaned up after themselves too! They didn't leave dust and debris everywhere. Very impressed and will hire again."

"Galvin came for the installation of the Nest thermostat but started by first fixing my heating gas furnace before installing the thermostat. He is a great resource! I highly recommend him."

"Punctual and professional. All of the work was completed right on schedule. They upgraded my entire home and replaced electrical panel. Definitely hiring again; I have them scheduled to repair the sprinkler system electrical work and the fans in both my bathrooms. The cost was surprisingly affordable! I cannot recommend enough."

"However, as of Monday it will be almost a week since I have heard back and the only feedback I got was a promise to get back to me by the end of the day with a quote after I EMAILED HIM!
I have had so many handmen and contractors not call me back, or are unavailable. I was really excited to find someone and get started.
I felt like it shouldn't take this long to get an estimate on the work and I would rather be told straight forward that the project would not be big enough or the schedule did not work. If I am having this much trouble getting an estimate, what about the work?
We are trying to decide whether or not to put our home on the market and this price weighs in our decision."

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.

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. 

To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.

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.

It is safe to run a generator continuously, but you must follow safety protocols to ensure personal and home safety. Read the manufacturer’s instructions for specific recommendations, but the general recommendation is to turn generators off overnight or when you’re away from the house. Overworked generators can pose a fire hazard and if your generator is not in a well-ventilated area, running it continuously could lead to carbon monoxide poisoning.
