"Joe showed up on time, did a great job, was super friendly and informative. Out of the six quotes I received for this project, his was the most reasonable and he was the only one who suggested a much easier way to complete my install compared to the other electricians who quoted my project. I will definitely be using Elevation Electric for my next project."

"I’m extremely pleased with the work Jon from TORQ Electricians recently completed in my home. This project was much larger than his visit the week before, and once again he delivered outstanding results. He replaced switches and outlets throughout the house, many of which had begun to fail due to age, and the upgrades have given us real peace of mind when it comes to safety. Jon also made several thoughtful recommendations—installing dimmer switches in the kitchen and study, and suggesting a different dimmer style for our living room ceiling fan. These changes have noticeably improved both the functionality and the atmosphere of those rooms. He even identified and replaced a GFCI breaker in the panel that wasn’t up to code, ensuring everything is now safe and compliant. The work has refreshed the look of our interior, and we couldn’t be happier with the results. We’re very glad we chose TORQ Electricians and highly recommend Jon to anyone needing professional, reliable electrical work"

"Tom was great at installing my RV outlet. Out of the 3 different quotes I received, he was able to get it done without trying to talk me into more expensive options. He was also accommodating with my somewhat busy schedule and very responsive throughout the install planning process. I would highly recommend Productive Electric."

"Just In Time installed a new attic fan and temperature control. The experience was great from start to finish. The first visit was a diagnosis and then an appointment was scheduled to replace the old fan with a new fan. The install of the fan was an excellent experience. The crew was able to arrive early, they confirmed it was OK to show up early prior. The install went smooth, the crew was efficient, friendly and cleaned up in no time. I would recommend and use Just in Time in the future!"

"Todd Chaney is an exceptional electrician. He has completed work for me on a mechanic shop, a vacation rental, and a mixed‑use retail building, and the quality has been consistently excellent. Todd understands the full construction process, which makes him highly effective at diagnosing issues and installing or repairing electrical systems in any situation — residential, commercial, or older structures. I’m hiring Todd, with Pink Brick Electric again this spring to handle major electrical work on my 1880 Queen Anne Victorian. Projects like this require experience, precision, and good judgment, and I trust Todd completely. He communicates clearly, gives honest and thoughtful feedback, asks the right questions, and respects the homeowner’s perspective. Working with him is straightforward and professional. The Pink Brick is a company built on integrity, and I recommend them without hesitation"

Generator Install questions, answered by experts

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window. 

Costs depend on generator type, labor, and additional wiring or transfer switch requirements.

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.

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.
