"I worked there for 2 years. Hired on as a helper and was promised after a year I’d get a promotion. Not only did I not get the promotion, my trainer did not train me properly. They stuck me with a garbage technician who flooded people’s houses out like he was a walking tsunami. Management does not care about you. Management cares more about what time they get home not you. Sure the hours are long, but they complain when you take your PTO. Expect your paychecks to be short too. Not only will they not get your paycheck right, but when they correct it they’ll tax it too. Yearly reviews are also garbage. They’ll grade you on everything; call backs, non warranties, how much damage you’ve done to a customer’s home. It isn’t bad that they review it with you, but some will effect you negatively on your closing rate if all you did was assist a technician and you didn’t sell it. I’m extremely upset regarding how they went about hiring me and training me. Extremely unprofessional and service calls are extremely slow. They were hiring way too many people when there wasn’t any work to be done. Some technicians even complained because they weren’t getting their 40 hours. The place is a train yard with more wrecked than salvageable. STAY AWAY."

Generator Install questions, answered by experts

No, you shouldn’t use an extension cord to plug a generator directly into your home without using a transfer switch. That’s because systems like pumps and HVAC fans need a steady power source that might not be available directly from your generator alone. If you bypass the circuit breaker box, you risk damaging your electrical system, creating a risk of electrical fire or electrical shock to you or any workers repairing lines on your local electrical grid.

As long as they have enough fuel, whole-house generators can run for weeks at a time (400 to 500 hours) without suffering too much wear and tear. However, this type of extensive use isn’t ideal if you want to extend the life of your generator.

Two important points. First, some generators may need you to periodically check oil levels every day or so and refill as necessary for safe operation. Second, if your generator uses a fuel tank, keep it regularly full so it doesn’t suddenly shut off. Many backup generators can run through a full tank in a day when they are powering large portions of a home.

If you’re deciding between a solar battery versus a generator for the best backup power solution, you can take a few factors into consideration. Solar batteries are quiet while generators can be quite loud. Generators have a lower up-front cost, but they require fuel and ongoing maintenance while solar batteries are more expensive but don’t have many ongoing costs.

Generator size requirements vary wildly among properties, but typical generator sizes are listed below based on home square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14kW

  • 2,500 sq ft: 12–16kW

  • 3,000 sq ft: 16–20kW+

Unfortunately, home square footage isn’t always a good indicator of generator size requirements. Instead, you should call in a professional to discuss which items in your home you’d like to run via your generator. They can calculate peak and average consumption for those items and then size your generator appropriately for optimal performance.

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.
