"New to the area, I needed a hookup for an emergency generator and EV charger. Cole came to my home, took the time to discuss different options and answer questions, and provided a detailed, written estimate, all the same day as my initial inquiry. The project was completed within a few days. His price was very competitive and his work meticulous. A true professional."

"i recently had a tesla charger installed, and i am extremely satisfied with the service. the electrician did an outstanding job he was professional, knowledgeable, and completed the installation much faster than i expected while maintaining excellent quality. the work was clean, efficient, and everything was installed perfectly. on top of that, his pricing was very reasonable compared to other estimates i received. it’s not often you find someone who delivers great workmanship, works efficiently, and offers affordable rates. i highly recommend him to anyone needing electrical work or an ev charger installation."

Generator Install questions, answered by experts

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.

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.

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.

In most cases, there are no tax credits available for home generators. However, that’s a general statement that applies to federal tax credits, so you might have access to state or local tax incentives. You can check the Database of State Incentives for Renewables & Efficiency (DSIRE) for more information about your area. If you hire a reliable home generator installer, they should also know if there are any state or local perks you can use to reduce your installation costs, including tax breaks and rebates.

In most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home generators. A permit for a generator usually costs between $50 and $250, depending on where you live. Your electrician or certified generator installer will usually pull the permit for you—and might be required to do so by your building department—but you’ll be on the hook for the cost of the permit. You should ask your installer before agreeing to any work if they will pull the necessary permits for your project.
