"Outstanding- John worked had to install the video doorbell, couldn’t get to work? Had the Ring Tech folks on the line w/him for 30 minutes! He checked lines, voltage etc. way beyond the call of duty! Ring determined the kit may be defective! He still installed everything to enable me to merely switch out the kit once it came! Very professional, efficient and kind! The system came on line by itself 4 hrs Later!?"

"Great follow through, good pricing. The generator required several trips and follow-up items because it required different inspections. They did a great job at following up on these steps and the generator works perfectly. Since that time we called them for some smaller electrical jobs. They are very detailed oriented, an example would be that I gave what I thought I wanted and they gave feedback based on their experience showing a better way to do it. I welcomed this and was happy they suggested it."

"I was extremely pleased with Viva Electric both times I used them. After encountering difficulties and a failed inspection with a mini-split AC connection using a different electrician, Jimmy and his team came in and provided a much better a much better and simpler solution. I used Viva again to install a transfer switch for a portable generator and was once again very pleased. Michelle in the office has been a pleasure to work with as well. I definitely recommend Viva Electric."

"Smart power source did a wonderful job installing my gas line. Jason was professional and very knowledgeable when speaking to him about my specific job. He made sure to explain how his crew would complete the job and what to expect. When his crew got to my house on the day of the install they were very polite and wasted no time getting to work. They where in and out with no wasted time. Fast and professional what more could you ask for. I would recommend him for every one."

Generator Install questions, answered by experts

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.

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.

Natural gas generators are designed to run for extended periods of time, such as power outages during a natural disaster. Since there’s no limit to the supply of natural gas, they don’t need to stop for refills. However, generators do need maintenance, including pauses to check and add oil. Constantly running them will also cause a lot more wear and tear, leading to a shorter lifespan.

Yes. You can connect your home back-up battery to a generator with its designated charger. Be sure that the output of the generator matches the input requirements for the battery for best results.
