"We originally hired Precision Electrical Services to fix faulty outlets and fuse box. We were impressed with their communication, professionalism, and quick scheduling that we hired them to install a ventilation / light fixture in our bathroom. I canâ t say enough good things about them and will use them for all of our electrical needs moving forward."

"I originally hired Services & More to cut my grass. But...one thing led to another. As I also had an issue with one one my windows. The trim was rotted and water was getting into the wall causing damage, along with that, we desperately needed to replace our shingles. My husband and I wanted vinyl siding done. Adam, was very helpful with the whole process. Before I knew it everything we needed done had gotten done, and then some. What I liked most about this company was he never pushed or tried to sell us on any services. We just happened to ask. Once again, Adam took care of what we wanted to do and more, because we asked, including our garden beds. When they did the siding, they replaced ply wood in the areas that needed it, and also repaired the foundation, in certain spots. Adam also did the interior of our wall, where that window was. ALL VERY reasonable in price! Considering that they did quite a lot. They are my go to guys!! I've hired them for life! Highly recommend!!"

Excellent experience"

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.

DIY is possible for basic setups. Professional installation ensures safe and proper electrical connections.

A portable generator can supply power to selected appliances and circuits in a home, but it's generally not designed to handle the entire household's electrical needs simultaneously. Portable generators have limited wattage capacity, so they are only designed to power essential devices and electronics temporarily until local power is restored. If your power needs outweigh the capabilities of a portable generator, consider installing a whole-home generator instead.

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

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.
