He came on time and he quickly assessed my garage and basement. He saw my charger and indicated that it's a plug-in which may cause some problems. He recommended a hardwire solution. Luckily my EV charger supplier was able to swap out the charger free of charge. Dave and team came on the scheduled day and installed the charger and connected it to my electrical panel. He labeled everything for me and showed me how it worked. Great value and great service.

I never had to make a request more than once (to remind them), and the ladder they used even had those soft feet at the end so it didn't bang against the side of my house. I also didn't see any of the small mistakes that I find contractors often make (eg trampling something I asked them to avoid). Oh and their price was lower than others I had gotten estimates from.

When I called them to come out and fix the problem they wanted to charge me time and a half for the service call even though I had a service contract. Their reasoning was that it was my fault that I didn't prevent snow from getting inside the air filter. They claimed to have sent out a mass email a month ago notifying all their customers of this possible issue, I never viewed it and no follow-up was ever sent. Not happy, now I'm looking for a new service company.

They get a star for being responsive and answering the phone, which some electricians simply don't do. Beyond that, they sent over what I guess was an apprentice and another guy who didn't say much. I called twice, including the day of asking if I needed to go out and buy a plug. They said no both times. They guys came over with no equipment despite me emailing a direct picture of what was needed, and unwilling to drive 3 minutes to lowes to get it. We got charged and they left. After an email complaint they offered to send them back to change a plug without another $250 fee. Since we planned on having them actually do the job, while they were out here we asked for another small job or two (including simply changing an outside floodlight). Here comes more diagnostic fees for their "expertise"... Overall there are more experienced places out there by far, and many that will charge far far less. If you are in a pinch and need to reach someone, "no job is too small" here....

We were in the market for a standby generator installation and contacted a small handful of…read morecompanies that serviced Southern NH. Generator Pro (Nashua) and NH Generator Installers (Concord) were the two companies that had the generator installation process down to a science as well as good reviews on other sites. We brought both companies out to give us quotes and the work came out to about the same price in both cases. We ended up choosing Generator Pro because (a) we didn't have to chase them down for the estimate after the visit, (b) the owner personally did the site visit for the estimate and seemed like a really good guy and (c) their communication skills were noticeably better than their competitor. Generator Pro ended up being great every step of the way to the finish line. The installation process is coordinated by Michelle, who is incredible at her job. When you undertake a complex job such as a generator installation, the person coordinating the work is just as important as the people actually performing the work. There are numerous steps along the way--choosing the right generator, getting it delivered and "set", gas hookup, electrical hookup, inspection, etc--and most of it has to happen in a certain order around the buyer's schedule. Some of the work needed to be outsourced to 3rd parties, such as gas work and electrical work. Generator Pro chose very friendly and competent workers for these tasks that we were happy to welcome into our home. When the generator process was complete, the owner (Doug) drove over to give us a personalized tutorial on usage. When you spend this amount of money on a purchase, you want to feel great about it every step of the way. Generator Pro gave us a level of service that never had us second guessing ourselves when we were writing large checks. We look forward to working with them going forward!
