"PowerUp electrical was very professional and came out numerous times to help a strange situation we had with running electric to our hot tub on our new build house. They were very helpful and did not even charge us for the return visits. We really appreciated using a company with such integrity and great work ethic."

"Joe was more than amazing. He was informative and very knowledgeable. He was a super nice guy and stayed way longer than I expected him to (on a Sunday) , but he told me he wasn't going until he had everything done for my power to be turned back on. I was not just impressed by him as a person and his knowledge, but by his work and work ethics. My old breaker box had wires crossed all over the place. When he was finished, my new one had every wire going straight down and over to the breakers; nothing crossed or twisted. I would not only highly recommend Mr. Electric, but I would recommend Joe! (No offense to the other employees) Totally satisfied and grateful for the service I got as our neighborhood was recovering from a tornado that Friday."

"Consistent, professional, personable… No notes! We contracted Loveland Home Solutions to update our aging home’s electrical system. (update panel, install new recessed lighting, add some new outlets, install surge protectors, etc.) Their responsiveness and professionalism exceeded expectations from bidding to work to follow up. Brendin was great at follow up, answering questions and helping us find the best solution for us. Austin and his team were great and respectful of our home and their work precise and thoughtful. They weren’t the cheapest bid in the pile, but the little extra in our mind was WELL worth the peace of mind and confidence to have true professionals on the job. We will definitely use LHS again and whole heartedly recommend them to anyone needing electrical work done. Great job guys - thank you!"

Generator Install questions, answered by experts

Yes, natural gas generators can work without electricity. Natural gas generators are a common type of backup or whole-house generator that operates when the electrical grid isn’t working. The trick is using a transfer switch (which usually needs to be installed with the generator) that safely switches the home electrical system from the power grid to generator power when needed.

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.

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.

These advanced generators use a key fob or a smartphone app to remotely start, which is ideal for getting power back on immediately without venturing outside. This feature is more common on whole home generators, but you may be able to find it on large portable generators, too.

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.
