"Travis came to look at the problem on a Tuesday morning. When I explained to him that lights in the house were flickering he became concerned and put my job on the top of his list. Once he arrived he immediately diagnosed the problem as many of the circuits in the box had deteriorated due to moisture in the line. He fixed the bad circuit in question and showed me the problem and explained that due to the age, oxidation, and rust that I may have future issues with the remaining circuits. I decided to replace the entire circuit panel and circuits as well as have a new meter with new wiring and drip lines installed on the exterior of the house, as the old meter was also corroded and detaching from the siding.. Travis returned early the following day at the exact hour we had agreed upon and worked a full eight hours to complete the entire job. His work is exemplary: very neat and methodical and whenever I had a question he would answer it in detail. His work was completed within the 2 days and came to approximately 10 hours in total. He supplied all the necessary materials and had everything he needed on hand in his truck.. I recommend him very highly as a skilled and experienced electrician located in Berkshire County."

"Stephen Moro is a conscientious, knowledgeable, likeable electrician, with integrity. He initiates communication and gets back quickly â which is important to me (and which other contractors could do much better at). He had 3 days of work to do in the house we recently purchased, and did that work in a complete and professional manner from set up to clean up. He had better ideas about where to install the outlets we needed, and let us know what work could not be done (within our budget) given the age of the house (110 years), and location or condition of existing wiring. His price for the 3 days of work plus supplies was fair and reasonable. Absolutely outstanding person and electrician!  Maria & JJ, Pittsfield MA"

"We couldn't have asked for prompter, more courteous, or more expert service. Chris correctly diagnosed and solved all our problems. He wasted no time, charged what we thought was a very fair price, and left us wishing all our experiences with service providers could go this smoothly. Next time we have an electric issue we'll definitely call Paciorek."

"My solar inverter stopped working in my existing solar system, and since my original installer went out of business, I had a hard time finding someone to replace the inverter provided by SolarEdge. It was a small job, and most large companies weren’t interested, while those willing to help were booked out for at least a couple of months. I contacted Justin, and he replaced the inverter within just a few days. He was very friendly, efficient, and offered a very reasonable price. Justin was also extremely knowledgeable, explained everything clearly, and kept me updated throughout the process. He arrived on time, completed the work neatly, and made sure the system was running perfectly before leaving. Overall, his professionalism, honesty, and dedication to customer satisfaction made the whole experience stress-free and smooth."

"We had a great experience with Andrus. Tony came out before our Kohler generator installation to clean up our electrical panel and did an incredibly thorough job. Everything was left clean and organized. The generator installation itself went very smoothly. The team was professional, knowledgeable and respectful of our property, and everything was explained clearly along the way. We're very happy with the finished installation and feel much better knowing we're prepared for the next outage. Would definitely recommend Andrus!"

Generator Install FAQs, answered by experts

Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.

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.

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.

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.
