"Colin was prompt with his communication, responded within 24 hours to any inquiries, and made smart recommendations when we hired him to install our L2 Charger and replace a burnt-out switch in our kitchen. He worked smart & safe and finished them both in less time than I expected it to take. We would hire/recommend Colin to anyone seeking big or small project repairs."

"Spencer and Logan O'Brien were amazing to work with. They, and their crew, were competent and trustworthy to be at our home during this construction job. Spencer is a very good communicator and responds to questions and requests in a timely manner. He was able to organize all the needed elements from land preparation to electrical to make the garage happen, leaving us with very little to worry about. We are completely happy with the end product of their labors and love how the new garage fits in with our existing home. We will absolutely look to O'Briens and Sons LLC for future projects around the home. Overall, the experience was professional, timely and a great investment! Thank you for making our garage come to life, Bill and Dierdra"

Generator Install questions, answered by experts

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

Many services include assembling the unit and securing it in the window. Confirm with your provider.

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.

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.

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.
