"Frank did a great job. He was very good with communication and I always knew what to expect and when. The job wasn't exactly easy (running a wire through my tight attic space and installing a car charger on the other side of the house from my box) but it went down exactly as planned and I'm pleased with the result."

"JP Services installed a Moen Flo water leak detector. The original pipe was a little short, so he extended it to install the device. The job was done well, but he had to fix a small leak he caused and left some residue from his blowtorch. Overall very worth the price."

Generator Install questions, 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. 

Portable generators provide backup power for essential appliances during outages and are easy to relocate.

With proper maintenance, a whole-house generator can last between 20 and 40 years. The specific lifespan depends on how often and for how long the generator is used, and some models may have their life expectancy rated in hours of operation. To maximize its lifespan, expect to spend around $150 to $300 per year for annual maintenance checks from a qualified technician. During these checks, a technician will inspect the engine filter, starting mechanism, fuel, lubrication, and coolant levels. Consulting your installer and choosing a low-impact fuel like natural gas or diesel can also help ensure your generator lasts as long as possible.

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.

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.
