"They did excellent work on many different items. Had a light installed over the sink (replaced a canister with light), re-wired outlets for kitchen remodel, and installed Ring doorbells. Showed up on time (key for me) and did nice work on all of the items. I would definitely have them do any other electrical work for me."

"Shawn Powell scheduled an installation and overview of my security system for 5/14/2021 and he was here promptly on that day. He had to detour on his way to my house but he texted me to let me know he was delayed. Shawnâ s customer service is impeccable. When he got to my house I had on my mask, he respected my home and put his on. When he had everything installed he gave me all the instructions I needed to use my system. If you want great customer service, a professional installer and top of the line security system for an affordable cost, Shawn is your man. I highly recommend him."

"Mr. Bailey was absolutely amazing. I have an older house and even simple projects become complicated fast. Mr. Bailey visited my home three different times and every time was a great experience for me. He showed up on time, every time. He was very easy to contact and he kept me informed of what was going on at every step of the job. He was incredibly professional even when my old house threw curveballs at him. I am so impressed with all of the work he did for me and my spouse and I will absolutely recommend him and hire him again if/when we need more electrical work done. Mr. Bailey is a joy to work with and he truly cares about his work. I can’t say enough about how much I appreciate him and his dedication to figuring out the puzzle of my house and making sure me and my family are safe in our home."

"Job nicely done. This was our second time using Southern and again found Chris the install to be timely, polite and kept the work area clean. $405 may be a little high for replacing a garbage disposal but I am happy paying the price to get the job done right."

Generator Install questions, answered by experts

The cost to install a whole-house generator averages $5,200, with a typical price range of $1,500 to $8,900. However, total costs can vary from $400 for a small portable unit to over $18,000 for a large-capacity system. The most significant cost factor is the generator's size and capacity, but other variables include the brand, fuel type, and labor for assembly and installation.

Generator costs can be broken down by type:

  • Portable or Emergency Backup Generators (1kW–7.5kW): $500 to $2,000

  • Partial-Home Generators (9kW–20kW): $2,000 to $6,500

  • Whole-House Generators (22kW–48kW): $5,000 to $18,000

To avoid paying for more power than you need, consider hiring an electrician to calculate the electrical load for your essential appliances. It is also recommended to get at least three quotes to find the best deal for your specific needs and budget.

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.

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.

While the rating will tell you how many watts the refrigerator needs at the peak of its cycle, it requires additional wattage to start. At the bare minimum, you’ll need a 1,500-watt generator to get the fridge up and running after a blackout. A 2,000-watt generator should be sufficient for most home refrigerators.

With proper maintenance, a whole-house generator can last between 20 and 40 years. The specific lifespan depends on how often and for how long the generator is used, and some models may have their life expectancy rated in hours of operation. To maximize its lifespan, expect to spend around $150 to $300 per year for annual maintenance checks from a qualified technician. During these checks, a technician will inspect the engine filter, starting mechanism, fuel, lubrication, and coolant levels. Consulting your installer and choosing a low-impact fuel like natural gas or diesel can also help ensure your generator lasts as long as possible.
