Derry Plumbing & Heating

Our 40 yr old boiler and water tank were replaced. Issac and Bryan were clean-cut, well spoken, polite; on top of that, they were good at cleaning up after themselves. We really appreciated them and am glad I asked my neighbor who he just used. That's why I called them. It worked out well and the office people were pleasant as well. Over all good teamwork must mean something at Derry Plumbing and Heating. Even the initial salesman who set the tone - not pushy, factual and the guys who followed him were just as nice.

Tyler and Aaron have been to my home twice. They're lovely guys, professional, knowledgeable, and willing to go above and beyond for the customer. I'm delighted with the work they've done. Every step was explained and they completed the work in a timely fashion, competently, and professionally. I can't recommend this company highly enough. If you have a plumbing issue, call Derry Plumbing and Heating.

I called Derry Plumbing and Heating because I was having an issue with my mini split system. They tried to help me over the phone and called me on face time to walk me through what I needed to try. I love that they tried to save me money first. When that did not fix, they sent Tyler out the same day. He was friendly and helpful to explain everything to me. He was considerate while I needed to take work calls and fixed my unit for me. He called prior to coming, arrived on time, was professional, and ensured everything was back in place and working prior to leaving.

Had a leak coming from my a/c unit in the attic. Two other plumbers couldn't find the problem. Tyler tracked it down and not only found the problem, but also fixed it in good time and a reasonable price. I'd recommend Derry Plumbing and Heating to everyone!

We had an issue with part of the house putting out heat when the thermostats were off. Ryan came out and was able to figure out the problem right away. He was very knowledgeable and gave us a quote for the work we will need to get in the near future to fix the problem. Will definitely be going back with this company when it's time to have those repairs, the company was very timely and professional

The older gentleman who came out was rude, impatient, and borderline vulturistic about valuing his time. Directly said multiple times he didn't want to be here and had somewhere else to be, and bluntly said I should just do it myself.
So I did it myself. The next day, he had the audacity to try to get me to let him charge the full $1,000 down payment on top of the $99 service call.
It is two star because they do know what they are talking about, and are very knowledgeable. Just be warned that they will pick your pockets clean if you let them.

During the recent -10-degree weather this past week our furnace decided to stop working. We tried to press the reset the button without luck and began reaching out to the oil company that supplies us with our home heating oil and a few others and although each had a an “emergency number” none answered. We left messages with hopes that somebody would call back. To our relief, Derry Plumbing and Heating reached out within the hour. The gentleman on the phone was extremely nice and asked a number of questions in order to get an understanding of what the issue was, and said he could have a technician to our house within a few hours.
About an hour later Tyler, the technician, called to let us know that he would be at our home in about 20 minutes. It did not take him long to identify the problem and he had us back up and running quickly. He spent the extra time with me to understand what had happened and before he left made sure that the heating zones in my house were working properly.
I could not be happier with the service and support I received from Derry Plumbing and Heating. Anybody can deliver heating oil or propane to your house, but the true test is if they are there when you really need them.

Josh and Aaron did a fantastic job installing our mini split system in our home. They were super professional, courteous, and went the extra mile taking time when the job was done to show me how to use the units and how to make our home more energy efficient. Very pleased and appreciative of the job they did!

Our Furnace quit working last night. So we called John at Derry Plumbing & Heating, this morning. John sent Tyler and Christian out and fixed our Furnace. Works Great Now. We are so happy. Tyler and Christian were Professional and provided Great Customer Service.

Derry Plumbing & Heating also installed an awesome Central Air Conditioning System in our house, earlier this Summer.

My review is Great People, Fair Prices and Excellent Work.

Mike and Christian installed a half bathroom in our basement. They were very professional and the quality of work was excellent. I would highly recommend them.
