"We had a humidifier installed. They installed it quickly and professionally. The installer Jimmy was very helpful and even gave me a couple pointers in regards to installing a wifi thermostat. I've always had great experiences with Kath/Aquarius home services and will definitely use them again."

"We needed an outlet and light + switch installed for our radon system. While the cost was a bit more than we were hoping, the person that came out had it done within 2 hours and its one less thing on our to do list! I also appreciate that Hero does not charge a trip fee like one of the other companies I had come give a quote."

"Excellent work at a fair price on a reasonable timeline. Kurt went the extra mile to assemble a chandelier that came in (literally) hundreds of pieces, and he was a pleasure to work with. We will definitely be hiring for lighting and electrical work in the future."

"Needed a dimmer switch installed in a double light switch. Tried to provide the dimmer switch but was unsure about the right one but that was unnecessary as the electrician brought one with him. Quick installation and pleasant to work with."

Generator Install questions, answered by experts

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.

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.

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit

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 safe to use as long as they are installed and operated correctly according to the manufacturer's recommendations. The most critical safety tips are to never use a portable or fuel-powered generator inside an enclosed space due to the risk of lethal carbon monoxide poisoning; always operate it outdoors where fumes can dissipate away from your home. Additionally, never attempt to connect a generator to your home’s electrical panel yourself—hire a professional to ensure the setup meets safety standards. Finally, avoid overloading the generator by not connecting more appliances than it is rated for, as this can damage your equipment or cause a fire.
