"Terrific job. Mock Electric installed a power line on an independent circuit for a new electric fireplace located about 100 feet away from our fuse box. They were on time and did the work in a thorough and efficient manner and on budget. Thank you for this recommendation!"

"The owner, David Smith, was able to schedule my job in a reasonable timeframe and kept me informed when an emergency delayed his arrival. He is very professional and knowledgeable, with a pleasant personality that made him easy to work with. He removed and replaced my foyer light fixture quickly and very carefully. His price for the job was quite fair and the 10% new customer/military discount was nice. I would certainly call on him for any future electrical work."

Generator Install FAQs, answered by experts

Natural gas and electricity rates vary significantly based on location, and pricing can change over time, too. It’s possible that in locations where natural gas is particularly inexpensive, it will cost less than grid-based electricity will. However, you should also factor in the generator’s initial costs and maintenance needs, as well as its noise level and if it can comfortably power all your home appliances.

Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.

Setting up utilities on a vacant property usually takes at least a few months, or between 6 weeks to 16 weeks. This process requires working with the local planning and zoning department, hiring a building contractor or engineer to design the utility layout, securing permits, laying the lines, and connecting the utilities.

You can expect a diesel generator to last for up to 30,000 hours of use, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two. 

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.
