"From getting an estimate and receiving the information related to the upgrade on my electrical panel based on having an older home which was grandfathered in. I felt more at ease and comfortable with the upgrade from Keil, the technician was professional and so was staff that provided the estimate. I would never hesitate on hiring Keil for all of my electrical needs."

"I’m very pleased with the bathtub replacement, Sheetrock installation, and painting work Cenarez Construction completed in my home. They were professional, reliable, and paid close attention to every detail. The bathtub looks beautiful, the Sheetrock was installed perfectly, and the paint finish is clean and even. They did an excellent job from start to finish, and I highly recommend their services."

"We bought an older house not knowing much about electricity, other than both of our vehicles are electric and need to plug in to charge. Long story short, we didn’t have enough electricity coming into our newly purchased home. We needed a complete upgrade. We got in touch in with Silvio and although what we needed was serious, he made it as painless as possible. He planned and coordinated everything. When the power company was there that morning to shut down the power, Silvio and his guys were there waiting with everything they needed. We had our power back on that very same day. They did a fantastic job at a reasonable price. Silvio kept his word and did everything he said he was going to do and we find that refreshing. 10 out of 10!!! Honest. Reliable. Trustworthy. Thank you SRM!!!! Definitely recommend and will use again"

Generator Install FAQs, answered by experts

Generators are safe to use as long as they are installed and operated correctly according to the manufacturer's recommendations. The most critical safety tips are to never use a portable or fuel-powered generator inside an enclosed space due to the risk of lethal carbon monoxide poisoning; always operate it outdoors where fumes can dissipate away from your home. Additionally, never attempt to connect a generator to your home’s electrical panel yourself—hire a professional to ensure the setup meets safety standards. Finally, avoid overloading the generator by not connecting more appliances than it is rated for, as this can damage your equipment or cause a fire.

If you’re wondering whether gas generators produce carbon monoxide, know that natural gas generators do not produce carbon monoxide if they are functioning properly, as natural gas burns cleanly. However, if the generator malfunctions and the gas does not burn completely, there is potential for carbon dioxide to be produced. To prevent malfunctions, it's crucial to perform regular maintenance, including running the generator weekly and scheduling professional inspections every 6 to 12 months. Also, be sure to test your carbon monoxide detectors regularly to ensure they function in the rare case of the generator producing carbon monoxide.

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.

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 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.
