"I cannot rave enough about Professional Systems Design. Initially, they came to my house by chance, but Iâ ve had them come back several times by choice. My husband and I had just bought a house that was in need of many electrical repairs. Our home warranty company sent out Jeremy and his company, Professional Systems Design. I had a list of things I wanted done and Jeremy and his team were able to do everything, working with the warranty company to get as many of the projects covered as possible. What the warranty company didnâ t cover, the charge to us was very reasonable. Since that initial visit, Iâ ve hired Professional Systems Design several times to complete more projects because they are honest, proficient, personable, and professional. Jeremy, the owner, is extremely knowledgeable and skilled in his area of expertise. The team installed new ceiling fans, fixed and added extra outlets, replaced old lighting with recessed lights, installed a camera doorbell system as well as a new bathroom exhaust fan, just to name a few things they did for us. Whenever I had a question or wanted an opinion about how to best accomplish what I wanted to in a room, Jeremy had the answer. Basically, Jeremy knows his stuff! There wasnâ t anything I presented to him that he or his crew couldnâ t do. I have 100% confidence in Professional Systems Designâ s ability and integrity, and I HIGHLY recommend them!"

"Came in, got straight to work. Lights looked amazing. Only problem was they wouldn’t patch 2 small holes from removing old fixture. I took care of it no problem but it would be common courtesy to take care of that for your customer. Other than that, honestly the guys were extremely professional. He wanted to make sure my lights lined up with existing fixtures so in an event I ever changed it, it could match and looked uniformed to the ones installed. I’d definitely use them again for sure."

Generator Install questions, answered by experts

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. 

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. 

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.

If you’re wondering if you can use your electric vehicle as a backup battery, it depends on whether your EV is compatible with bidirectional charging. This technology allows energy to flow both ways, enabling vehicle-to-home (V2H) backup power, vehicle-to-load (V2L) for appliances and camping, and vehicle-to-grid (V2G) to support the power grid. Compatible EVs convert stored DC energy into usable AC power, helping reduce energy costs and enhance grid stability while providing emergency backup power.

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.
