"Job: install fan and switch for it in spot with no electrical box yet. 1 hr 56 min arrival to departure. Pros: Called me the next day after reaching out through Angie. Friendly to talk to during booking and while working at the house. The work went well nstalling the ceiling fan and a switch for it where one wasn't. Cons: Never quoted job (figured it couldn't be that bad for a fan install so didn't ask - big mistake) and appointment was a month out for 7:30am on a Friday. Informed them I worked nights at the time of booking. They text me at 6am that day to inform they'd ould be late and arrived at 9:46a (I'm 25 hrs awake at the point they arrive). Invoice for $737 comes across. Inquired about the $300 for labor for one and $375 for labor for the other and was told "We usually charge round trip, and I only charged you one way. And there was no existing switch or fan location,if it was as simple as just changing a fan out there would have only been one". Double labor charge unfair."

"First of all, Manny was on time and as polite in person as over the phone. Manny worked very conscientiously from the start to the finish of both of my projects. He takes doing a good job seriously and is very efficient. I am fully comfortable with giving his name and number out to friends and family. I've already given it to my employer. In the future, I plan on calling them for all electrical needs. The price compared well with others in the area."

Generator Install FAQs, answered by experts

A home that is 2,500 square feet will likely need a 20kW to 25kW generator. Consult your local generator installer to confirm the generator size needed to power your home before purchasing a new one. Be sure to consider how much power your necessary devices need to run.

It might seem counterintuitive, but installing a generator transfer switch will save you money in the long run. While you’ll have to pay between $400 and $2,500 to have the transfer switch installed, you’ll recoup that amount later on when you don’t have to pay for expensive repairs to your appliances, devices, and electrical system that may have burned out, overloaded, or stopped working due to a sudden loss of power or an incorrect hook up of a generator to your home. 

You may need a permit for a portable generator if you’ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.

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.

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.
