"I can’t recommend Botelho and Sons Electric highly enough. From start to finish, the experience was outstanding. They were punctual, neat, and completely reliable, showing up exactly when they said they would and keeping the work area clean and organized throughout the entire project. I had a 200-amp panel upgrade, lines run to a pool & hot tub, copper wire installed for the pool and the connection for our generator - everything was done to code, with obvious skill and attention to detail. Out of 6 electricians I got quotes from, Ryan offered the best price without cutting any corners. On top of that, both he and his employee were incredibly knowledgeable and professional. Bonus points for being amazing with my 130 lb Cane Corso, who is usually suspicious of strangers. It was clear they were comfortable around dogs and respectful of my space, which made the whole process that much smoother. If you want high-quality work from someone you can trust, I wouldn’t look any further!"

"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!!"

Generator Install FAQs, answered by experts

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. 

To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back 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.

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