"Chris gave us an estimate and the guys came 5 days earlier than originally scheduled. They were great, efficient, neat and a pleasure to work with. They managed to install a chandelier in a room that never had one with very little intrusion to the ceiling. A little drywall patching and painting and we will be done which I can do. The estimate was fair anc I will definitely recommend to others"

"I had an excellent experience with Clinton Electric Co. overall and the electrician they sent, Eric Shipley. Communications before the visit were prompt, professional, and geared toward promoting confidence. Electrician was also courteous and professional throughout the visit, provided excellent communications as to expected costs and the diagnostic he was performing, and performed the work quickly and efficiently (tested the wiring, replaced electrical outlets, installed new circuit breaker, and tested to confirm all outlets and the dishwasher were working). Provided email with invoice before leaving the visit. Company communications practices geared toward safety and inspired confidence - dispatcher provided name of electrician before visit; company also texted and emailed photo of electrician prior to visit. Electrician wore mask and followed safe COVID-19 practices. I was very pleased and would use this company again, as well as highly recommend them."

Generator Install questions, answered by experts

While natural gas generators are costly, they’re a great option for standby power due to the reliability of natural gas as a fuel source. Unlike other fuels, natural gas is delivered through underground pipes, making outages extremely rare and less likely to be affected by the elements. As long as the area isn’t prone to earthquakes, they offer an unlimited supply of natural gas that doesn’t degrade over time or require storage in tanks.

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.

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.

It’s usually better to repair your generator if it isn’t working properly, as it will typically be much more affordable and should yield similar results. Generator repairs cost around $300 on average, while installing a new whole-house generator costs around $5,000 on average. The only exception is if you know your generator is reaching the end of its useful life, usually between 30 and 40 years. If you have an older generator, you could face multiple repairs in the coming years, which might mean that a full replacement will be more cost-effective over time.

The amount of time a standby generator can run continuously is around 3,000 hours on average. However, standby generators can generally run indefinitely as long as they have a continuous fuel supply. Generators hooked up to a home’s natural gas supply are the best option for extended usage, as these won’t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won’t last as long, as these require fuel storage and regular refueling to stay running.
