"We really like the professional job done by Paul, James III and Nate, they answered all our questions and explained everything to our understanding. They are no doubt well-trained in their field and dedicated to the reputation of the company. Kudos to our saleperson Tom, who also happens to be the president. We had on-location visits from 3 companies to have a whole-house generator installed and no doubt picked the best company."

"Mike went above and beyond for me today. I need the generator for medical and respiratory equipment and Mike rearranged his schedule to get the generator running today! Very knowledgeable, and someone I immediately trusted and felt blessed by the introduction and service he provided to me and my family. I would strongly, recommend Reliable Power Systems and will certainly continue to call on them."

"Pleasure to work with on recessed lighting install. Ken was responsive to questions and time changes via email/phone. We removed the old lighting, did some of the recessed lighting layout, and obtained the materials (he reviewed to make sure it was OK). His installation and electrical work was handled professionally and on schedule. Any adjustments were reviewed with me as a courtesy. We thought the price was fair for the work done. Nice job."

"I recently hired this electrician for a panel upgrade and some additional electrical work in my home, and I couldn?t be happier with the results. He was professional, knowledgeable, and completed the job quickly without cutting corners. Everything was explained clearly, the work area was kept clean, and the final installation looked extremely neat and high quality. You can tell he has real experience in both residential and commercial electrical work. Communication was great from start to finish, pricing was fair, and the work was completed on time. I highly recommend him to anyone looking for reliable electrical services, panel upgrades, lighting installs, troubleshooting, or home automation work. Sent from my iPhone"

Generator Install questions, answered by experts

DIY is possible for basic setups. Professional installation ensures safe and proper electrical connections.

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.

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.

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.

While diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.
