"What a great experience! From introductory call through bidding process to delivering all that was promised, Zach was fantastic. Main job was replacing panel but we discussed numerous scenarios for add in’s that include outside hookup for portable generator, power to a shed in back, future EV charging station etc. Zach was very knowledgeable in all areas. Quotes for all options were broken down in modules that made it very clear and easy to see actual cost of each segment of potential job. This made it a breeze to finalize job quote. Communication throughout process was fantastic and pricing fair. I highly recommend Zach and Tech Connect. They will be my go to electricians in the future."

"I would like to recommend Joshua Smith as a Tesla installer and overall electrician. He did a great job for my wife and I on the installation of our powerwall 3 and car chargers within our garages as well as trouble shooting some other electrical problems at our new home at Smith Mountain Lake. Additionally, he answers phone calls and shows up on time. Again, we highly recommend Joshua."

"Things went very well! Ostrom customer service called to alert me in advance that the electricians were on their way, and told me whom to expect. The electricians arrived on time. They were very courteous and professional, and Daniel was very knowledgeable. They knew just how to approach the job and completed it well. For the electrical system safety check, Daniel checked the main electrical panel, the outdoor electrical equipment, the branch circuit wiring, and life safety equipment. He gave me a written evaluation and list of recommendations. It was definitely worthwhile having this done because it made me aware of things that need to be addressed. Daniel just a few days ago installed the wiring for the under-cabinet lighting, and is waiting for the tile work to be completed before he installs the lights. Since they haven't yet been installed, the cost of service noted is only the cost for the chandelier installation."

Generator Install questions, answered by experts

Yes, in some locations, it is required by the National Electric Code (NEC) to have a transfer switch installed for electrical emergencies. In addition to following electrical code, generator transfer switches ensure your home is fully protected during a power outage. By switching the power from the main breaker to the generator breaker, you can seamlessly operate your HVAC, lights, appliances, devices, and more during an emergency. 

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.

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. 

In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.

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.
