Bill Trombly Plumbing - Heating - Cooling - Electric is a family-run plumbing, heating, cooling and electrical company based in Manchester, New Hampshire, self-reporting 53 years in business since Bill Trombly founded it in May 1973, with his son Bill Trombly Jr. buying the business and becoming president in 2006. Google reviewers rate the company 4.7 out of 5 from 596 ratings, and years of detailed write-ups repeatedly name individual technicians for thorough, well-explained work — mini-split and central-air installs, septic and drain repairs, water heater replacements, and electrical fixes. Several reviewers describe fast response, including same-day or within-the-hour arrivals for a burst pipe and a sewer backup. Worth asking about before booking: a December 2025 reviewer said an emergency no-heat/no-water call was declined because they were not an existing customer, and a January 2023 reviewer said the company refused to send anyone for a 94-year-old relative's no-heat emergency. Other reviews describe billing disputes over a trip-charge fee, a technician unfamiliar with servicing a whole-house generator, and a rescheduled appointment pushed back roughly 60 days. The company's own website and a 2024 news article both state it has recently joined forces with Sanford Temperature Control, to be led going forward by Sanford's owner, Rich Jordan — worth confirming directly who is running the job and the current status of the crew and licensing before scheduling work.
“This month, Sanford announced it “joined forces with” Bill Trombly Plumbing Heating Cooling Electric. The company will operate under the Sanford name and be led by Sanford owner Rich Jordan.”
Have an emergency, got a call where the person told me since im not an existing customer he won't make the emergency visit. In the meantime its 20 degrees and I have no water or heat
I wish I could give negative number of stars. I am complaining to the state of new Hampshire. Recently I had an issue with the pressure relief valve installed on my well pressure tank. It started to leak. I called for an appointment and was told that the fee for the visit was $120 before any work was done. The next day Jim arrived in the mid-afternoon. I showed him the tank, pressure switch and relief valve. He worked on a tablet pc for a minute and then told me it would cost $500 just to diagnose the issue. That was in addition to the $120 for showing up. I knew the issue. The possible problems were the tank, switch and valve. I told him there was no way I would pay $500 for diagnosis. Out of curiosity I asked how much to replace all the parts, Tank, Tee, Switch, Pressure relief valve, and pressure gauge. He came back with a price of $5001.00. I was incredulous. I knew that all the parts were under $600. I was expecting an estimate of $1000. I said no way and paid him the $120 for showing up. I went to F.W Webb, purchased all the parts for $550, and did the job in three hours. Both the cost to diagnose and replace the components were criminally high. There is now way that can be justified. Never do business with Bill Trombly \ Sanford. Especially if you are not knowledgeable about the systems you need help with
Don't call this company if you need a generator serviced. We hired them when our whole house generator hadn't run for a couple years and the technician they sent out had no idea what he was doing. He spent 4 hours on the phone with the manufacturer without performing any real work and when he was done he stated that the generator was dead and needed to be replaced. We were then contacted but a sales person to set up an appointment to get an estimate for a new generator. In the meantime we received a bill for 4 hours. When the estimator arrived, we complained about the bill and he stated that all they could do is credit that amount if we purchase a new one (estimate was ~$15,000). I ended up calling New Hampshire Generator a week later and they had it fixed in 2 hours (read my review of NH Generator for more details). After watching the techs from both companies in action, it was obvious that the Bill Twombly tech was not qualified to work on generators. He new nothing about small engines and you need an engine mechanic to repair generators that won't run. How do you justify billing someone for work when you send out an unqualified tech? Maybe you don't need to know anything about engines when you install them, but don't tell customers you can repair them and then send out an electrician (or whatever he was). Guess which company I will never hire in the future? PS: After reading other negative reviews that Mr. Twombly responded to, I'm looking forward to hearing some lame excuse from him on why it's my fault the technician didn't do his job. And no Mr. Twombly, you won't find my name in your system because my girlfriend made the phone call and wrote the check therefore you can't use that as an excuse either. I was standing next to her when she made the call and we made it very clear that the engine wouldn't start - we weren't vague in any way. This occurred a few years back, but if you really want to put your money where you mouth is, please reach out to me and offer to reimburse me for the 4 hours of work your tech did *not* perform. Perhaps I'll consider removing this review. If you ask why I'm posting this review years later, the answer is simple. NH Generator performed maintenance on our generator today and I felt it was to time to write a review for them because they have been such a great company to work with. Every time they visit it reminds me of the poor experience I had with your company and I would be remiss if I didn't also write a review of that experience.
The technician was awesome. Nice job thank you
Edited - In response to the businesses response….my name was on the credit card. I had originally posted a lesser fee than was actually charged and I’ve updated the fee to be called the same as on the invoice: Was charged $115 for a “trip charge” to fix a minor leak in shower and to determine what was causing a leak at outside water faucet. Some screws were tightened on the area where water is turned on and we were left with advice to caulk (ourselves) around that….really plumber? The shower leak was supposedly fixed but after one day - it is not (after paying $250 total for the tightening of some screws). Also, was told to call back in the spring to fix the outside faucet leak (was a sunny day). Received communication that we’d need to pay the $115 “trip charge” AGAIN for them to come back for the repair we already reported. The plumber was very nice. But this is bad business.
