"TriCat is very professional, clean, and prompt. Angelo is great and knows exactly what needs to be done. Their prices are also fair and comparable to other electricians in my area. The job was done on time. This is very important when trying to keep the renovations on schedule. I would definitely recommend them to a family or friend, and use them again myself."

He also gave us advice on other things we could fix in our home. Kevin is reliable, trustworthy, kind, and passionate about his work! Will definitely be calling him in the future for more work!"

"Fast and super helpful. Gave me a proposal right away. Started work same week. If deviations were needed, was specific on what and why. Reasonable and fair pricing, and honest about their capabilities and areas of expertise. Professional team and went out the way to provide additional references for other concerns. I also appreciated the video Fabio took to show me the before and after, especially in areas I was unable to see."

"I had a great experience with Albert. He was extremely professional and easy to communicate with throughout the entire job. He clearly explained what needed to be done, kept me informed, and made sure everything was completed properly. He installed several outlets and fixtures in my home. He was careful, clean, and respectful of my space, leaving everything neat when the job was finished. I highly recommend Albert and this company for anyone looking for reliable, professional electrical work."

Generator Install FAQs, answered by experts

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.

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.

You can expect a diesel generator to last for up to 30,000 hours of use, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two. 

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