"William was prompt, set expectations and followed through and educated us on the need for a Surge Protector. He came for a quote but was able to install the EV charger quickly and cleanly same day. He is very knowledgeable about the EV market and was in and out quickly. Great experience all around. Highly recommend!!"

"Actually, Power and Control Installations did much more than install electrical switches, outlets and fixtures. They installed a new 20 amp breaker, and ran wiring 60 feet underground to my new shed. The electrician they sent out was very professional, courteous, and answered all my questions. The work was completed to my satisfaction. I would highly recommend this company to others."

"The whole experience from start to finish rates a 5, I would go higher if I could. Dexter returned my call right a way and scheduled a time to come by. (Not a time frame) on arrival he was very courteous and professional. Went the extra mile to make sure that fan was installed properly. Once done I was asking some questions about changing some light fixtures and replacing a exhaust fan in the bathroom in the near future, he checked out the fan and got it running before he left. Great guy I will definitely be calling him back in the future and will recommend him to our friends.."

"Chris Ayarza came in and completed the job perfectly, even helped with assisting on a couple electrical jobs I had planned to take on myself. When the job was completed, I noticed the AC stopped blowing cold air but they came in next day to finish up with labeling our new panel and also spent some time to fix the issue. Overall great experience and learned some new tricks too"

"I'm blown away by the fantastic service. I was trying to get ready for Hurricane Matthew and needed a generator outlet installed. Called and got a call back immediately. Ken was great to work with, installed the outlet while I had to head out of town. I was extremely worried about the hurricane and Ken's was so helpful that I knew we'd have what we needed when the storm hit. He even checked our old cable and suggested that we buy a new one, stayed on the phone with my wife to make sure the right one was ordered. I can't say thank you enough. This is why you deal with highly reputable local companies, they go the extra mile. Highly recommend them without reservation."

Generator Install questions, answered by experts

Setting up utilities on a vacant property usually takes at least a few months, or between 6 weeks to 16 weeks. This process requires working with the local planning and zoning department, hiring a building contractor or engineer to design the utility layout, securing permits, laying the lines, and connecting the utilities.

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.

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.

Yes, natural gas generators can work without electricity. Natural gas generators are a common type of backup or whole-house generator that operates when the electrical grid isn’t working. The trick is using a transfer switch (which usually needs to be installed with the generator) that safely switches the home electrical system from the power grid to generator power when needed.
