"I was very pleased overall with the work that was completed. They were able to install a new ceiling fan and get an existing fan going again. They installed two switches and one outlet. As with all electrcal projects , items came up and the ended up having to cut some drywall to pull wires. No change in price and actually got all repairs done for less than quoted as we did not have replace the old ceiling fan."

"I needed an additional lighting fixture wired in and mounted above our pantry as well as an outdoor outlet in our patio ceiling, Cool Hand crushed it! They were extremely respectful of our home and wore disposable booties over their shoes every time they had to come inside from the attic or backyard. The install was extremely clean & professional, and of course worked flawlessly. Luke was very kind to our curious daughter who didnâ t make his job any easier! We wouldnâ t hesitate to hire them for the next project, they are 1st class."

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.

Yes, in most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home models. Because these installations involve significant alterations to your home's electrical system and produce exhaust fumes, local governments often require a permit or inspection for safety purposes. A generator permit typically costs between $50 and $250, depending on your location. Your electrician or certified installer can usually handle the permitting process for you, but you will be responsible for the cost. It's a good practice to confirm with your installer that they will pull all necessary permits before work begins.

While diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.

If you’re wondering whether gas generators produce carbon monoxide, know that natural gas generators do not produce carbon monoxide if they are functioning properly, as natural gas burns cleanly. However, if the generator malfunctions and the gas does not burn completely, there is potential for carbon dioxide to be produced. To prevent malfunctions, it's crucial to perform regular maintenance, including running the generator weekly and scheduling professional inspections every 6 to 12 months. Also, be sure to test your carbon monoxide detectors regularly to ensure they function in the rare case of the generator producing carbon monoxide.
