"Mike was great! He was quick to respond and had experience installing EV charging stations. We set up an appointment for him to come and do the work and he arrived at exactly the scheduled time (7:30 AM!). Once at the house he set about doing the work and in a short time he was done and ready for us to try the new charger. The quality of the work was superb and he could not have been more pleasant! And best of all his rates were more than reasonable. Mike is now our official, go to electrician!"

"I was waiting for a utility pole and service to be installed. Roy will put in a temp service when CMP completes the job. Roy hasn't done the work yet but he came out to the jobsite when I called him. I recommended him to my sister in Old Orchard .He did some work for her and they are very satisfied with the work and service."

"Not only did the electricians promise to come to install the stovetop as soon as it came in, they came a few days after we first made contact to see what the work would entail and agreed to dispose of the cracked stovetop for us. They kept their promise by coming the day after the stovetop came in, worked efficiently and made sure it worked properly before leaving. My husband and I were extremely impressed with their work."

Generator Install questions, answered by experts

Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.

Setting up utilities on a vacant property usually takes at least a few months, or between 6 weeks to 16 weeks. This process requires working with the local planning and zoning department, hiring a building contractor or engineer to design the utility layout, securing permits, laying the lines, and connecting the utilities.

In most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home generators. A permit for a generator usually costs between $50 and $250, depending on where you live. Your electrician or certified generator installer will usually pull the permit for you—and might be required to do so by your building department—but you’ll be on the hook for the cost of the permit. You should ask your installer before agreeing to any work if they will pull the necessary permits for your project.

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.

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.
