    One thing to note is that you will pay a service fee but its now the industry standard and theres is cheaper than any in the area.

    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!

I would strongly recommend Generator Pro for general maintenance or electrical issues on your home generator.

    SCAMMERS. Full stop…read more I live in a rented condo. I called the non-emergency line and left a message asking for a callback so we could schedule service as soon as possible. I did not request emergency service. Someone called me back and said they were already out on another call and could stop by. So they came by. The next day, my landlord was billed an over $200 emergency fee. When I called to dispute it, the first person told me, "Because you said 'as soon as possible,' we treated it as an emergency." That is flat-out false. Asking to schedule something as soon as possible is not the same as requesting emergency service. The first woman also stated that I said I was not available on Monday. In my message I said I would be out on Monday but my husband would be in and out and could arrange a time. We lived with the issue for days and did not need it immediately. The call was then escalated to "Shannon," who claimed I must have used the emergency line. I absolutely did not. Shannon kept telling me that I must have called for emergency. I did not. Their phone system clearly separates the emergency option, and I intentionally used the regular line. I even warned my landlord before the technician arrived that I had NOT requested emergency service and that I was very surprised by the callback. See Picture below. This is a classic bait-and-switch. The technician himself was professional and helpful--and ironically, we were actively considering service plans as we are in the process of working to buy this condo in the near future. We were going to inquire on service plans and other work with this company. After this experience, I would rather pay more somewhere else than deal with a company that inflates charges by re-labeling routine scheduling as an "emergency" and flat out lies and is deceitful. Be very careful leaving messages with this company and be careful as they lie to cover up. They quietly convert non-emergency requests into emergency calls and then hit you with an over $200 fee after the fact. Completely dishonest. (The photo below is the text I sent to my landlord the NIGHT this happened when I got the call from their tech. My mother worked with Carrier rep in the past and I know about "emergency" services so I gave him a heads up in case).

    Very disappointed in the customer service of J&J Heating and Air conditioning. We hired them to…read moreinstall a new heat pump to replace the old a.c. unit. Not only did the new system not work, it took them an entire week during a heat wave to come and remedy the problem. IN the meantime we saw that the ceiling in our home below the location of the equipment had a large water stain requiring the ceiling to need painting. J&J's approach to customer service is to first ignore the problem and then insult the customer and not provide any apology or fix to us. Do yourself a favor and look elsewhere for your HVAC needs - wish we had.

    We had our HVAC and tankless unit installed by MillTown in 2020 as part of a hydronic heating…read moresystem. A month ago, the commercial‑grade tank they installed failed. Rheem covered the tank under warranty, but MillTown charged $5,800 for the replacement which was essentially a retrofit with minimal changes. After reviewing the work, it was clear the job should have been closer to $3,000 based on industry standards and actual scope. Unfortunately, the workmanship was disappointing. The system was left in a condition that doesn't reflect professional standards -- including a drain valve positioned against another pipe, making it impossible to drain the system properly. I provided photos and a detailed email to Milltown expressing these concerns. Their response was that there "wasn't much to do," and they offered only a $500 credit toward a future service. Given the excessive pricing and the quality of work, a credit for a future service wasn't a reasonable solution, and I declined it. Another concern: their website offers no way to contact the owner or any managers directly. For a company that presents itself as family‑run, that lack of transparency says a lot. Overall, the experience was frustrating from the high cost to the poor workmanship to the dismissive response. Based on this, I cannot recommend MillTown for plumbing or HVAC services.

The lead tech tried to sell us a maintenance plan to get any kind of reasonable discount. Overall, I found their prices way to high. No thanks!! Milltown...people still work for a living. Merry Christmas Slower season? Isn't this heating season (busy)? Nobody wants to pay for you to train your staff.
