"Hired “Power Up” to refit our electrical panel and install an outside connecting plug to run a new portable electric generator. Jeff came out and spent time to evaluate and discuss our needs. He was consultative throughout the whole process. Lisa was responsible for arranging installation and paperwork and was very responsive to inquiries as well as reaching out to confirm things were moving forward. Justin was our installer and he knew his stuff. Very friendly and completed the work on time and as expected. Great experience working with “Power Up.”"

Customers say: Quick response

"Tom from Synergy did the bid for under cabinet lighting install, however sent someone else to do the job. Originally discussed with Tom that he would use a regular converter box inside the cabinet and place a dimmer switch on the wall, but the other guy he sent wasn't aware of this and placed the dimmer converter in the cabinet. This has resulted in us having to use the dimmer switch inside the cabinet instead of on a wall switch -- not what I requested. Also, I discussed with Tom installing an additional outlet in our kitchen during the bid process. After he left I noticed he did not include that on the written bid. The guy he sent didn't know about it either. The outlet was installed however. Overall, I was charged $95 additional over the bid and didn't get exactly what I wanted in regard to the dimmer switch for under cabinet lighting. Both electricians were very nice and professional, but there was definitely a communication problem in regard to the installation of the under cabinet lighting. Perhaps I should have clarified the issue more strongly, or perhaps I didn't understand. Either way, I'm happy with the lighting overall, but not 100%."

"These guys were great. Needed a Tesla home charger installed. Had two other quotes from different companies that said I had to do extra upgrades to get it installed. Power Up said the upgrades weren’t needed after all and was able to do the install for half the price of the other guys. Would highly recommend!"

"Paul came over early in morning and gave us a bid to install two ceiling fans and a bathroom light fixture. He said the fee would be $180 for each fan and $80 for the light fixture plus an $89 service fee. Bid seemed high, but he said he could do the work that day, so we went ahead. He was very professional and informative. Did the work efficiently and was courteous. The fans and lights work well."

Generator Install questions, answered by experts

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.

If your home already has a grinder pump and you’re still noticing issues (like frequently clogged toilets and sinks), it could be time to upgrade your grinder pump. Start by checking your existing horsepower. If there are four or fewer people living in your home, using a 1/2-horsepower grinder pump should be sufficient. Larger households should consider investing in a 1-horsepower grinder pump to maximize wastewater removal efforts.

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.

While natural gas generators are costly, they’re a great option for standby power due to the reliability of natural gas as a fuel source. Unlike other fuels, natural gas is delivered through underground pipes, making outages extremely rare and less likely to be affected by the elements. As long as the area isn’t prone to earthquakes, they offer an unlimited supply of natural gas that doesn’t degrade over time or require storage in tanks.

In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.
