“It was a combination of things. They always do very good work, extremely conscientious about doing it the right way. They always do a little bit more than is necessary just to make it done right. They are clean. It always looks great when it's done, and have been very responsive. I've just been very pleased with them. They did plumbing and electrical and HVAC. Most recently, they installed a new hot water heater. They did a heavy upgrade of our electrical system, so they replaced a whole circuit panel and they basically rewired the circuit in the power end of the house. They actually replaced our heater and air conditioner over a couple of years. I'd give them an A+. I actually have recommended them quite a bit.”

We've always been very happy with them. They worked on the HVAC. The first guy installed a new thermostat. That was shortly after we moved in. He installed a return vent in our basement. Those are the only two things they've done besides just service our heating and air conditioning. I'd give them an A+ overall. They always call when they're on their way so I know to be expecting them. I make sure that I'm home when they get here.”

I had them on an annual contract and they maintained my heating and cooling systems. They actually installed them too. Many, many years ago, they did basic electrical work for me.

“I do property management so I've had several experiences with them, and all but one, it has been very positive. They did heating and cooling and plumbing. They replaced one unit. They did basic work on a hot water heater. I'd give them an A overall. I only had one experience with one particular repairman that was not good, and I did tell them about it. I won't ever have him come again.”

“I had them come out for two separate things. The first time I had them come out and do some plumbing. They did an excellent job. They were timely and efficient. The job was completed, and our problem was corrected. The second job was the air conditioning unit. I think there was a part that needed to be replaced, and they replaced it. We actually ended up replacing the whole unit later on down the road after that visit, because it was an old system. It had the old Freon that could not be replaced any longer. It could've been, but it would've been extremely expensive. I'd give them an A.”

They installed the unit, too, so I have a contract with them—twice a year, they come in and service it. We had a neighbor who used them, and he recommended them. We had some other company that we were tired of using. Our neighbor recommended John Nugent & Sons, and we've been happy ever since. I'd give them an A.”

“I wasn't home, but my husband said they were interested to know what was going on. They did fix whatever problem we had. We haven't been having any problems with the heat. We're planning to change the whole unit, so we're probably going to call them to do that. It's old, even for the air conditioning. They just did repair work. I called the company from Best Pick Reports. I'd give them an A.”

“They were good. They were skilled in their field, and they knew what they were doing. It was HVAC installation. I would recommend them to family and friends. The workers were good—they were tidy, clean, and knowledgeable. They wore little booties, too. I'd give John Nugent & Sons an A grade.”

“The fan wasn't working, and the compressor outside wasn't working. I said, 'I don't think that's the way it's supposed to be,' so they looked at it and said, 'Well, we're going to have to replace something.' They did a very good job. They took care of it, and things were done very well. I've been using them for a while. I would recommend them—I've enjoyed all the work they've done. I'd give them an A; I have no complaints.”

“I've used John Nugent for heating and air for about a year and a half now, and it has been positive. The technician was incredibly well informed—he knew exactly what to do. He serviced our furnace and checked our hot water heater. He was very courteous, too, and I feel like he was very trustworthy—A+.”

“I have been using John Nugent & Sons for as long as they have been in business—I was one of their first customers.

The technicians that come out are excellent, and they clean up well after their services. They're an A+. I would recommend them to a friend or a family member.”

“John Nugent & Sons did some work for me. I had a positive experience because of Carl—the original salesperson who came. He was very thorough and knew what he was talking about—very educated and very reliable. He educated me on the system that was right for my home. He was very knowledgeable and very professional, with courteous service. He was really the reason I decided to go with John Nugent. I had my entire heat pump replaced, and everything is working OK now. The guys who came and actually installed the system were fantastic. They wanted to make sure everything was working properly before they left, and they were very professional and very conscientious. It was just all-around an enjoyable experience. They get an A+.”

“I've used John Nugent the last five years. It has been a positive experience. The workers and customer service are fantastic. I've had two furnaces replaced by them—HVAC systems—and they come annually to service. I would rate them an A.”

“John Nugent & Sons did my HVAC system. I was very satisfied with their work—no complaints whatsoever. They showed up on time, they did the services that were contracted, and they actually completed the work early. They were supposed to be here until four or five, and they actually finished at about three or so. They put in a completely new heating and cooling system. They also did some plumbing work—the best way to get to the plumbing was once I was going to replace the unit, so they did plumbing work as well. This was the first time I used them, but I would definitely contact them in the future. They were an A.”

“We're very pleased with John Nugent & Sons' work. They were very thorough, they were very precise, and they did exactly what they said they would do. I have no complaints at all. They put in a new air conditioning unit for us over a year ago. They responded for our service in a timely fashion, and they were able to do the job in a timely manner. They had done work for our son, and he recommended them to us. I would give them an A+. I would recommend them—we were very satisfied with their work.”

“Everything happened on schedule, and I liked the friendliness, good work, and general professionalism. They installed a new HVAC system and water heater. Everything has held up very well so far. I have been using their service since April, and I would use their service again. I'd grade them an A+.”

“John Nugent installed a furnace and a generator, and they seemed to be very professional. The installation crew that came out knew what they were doing—they made some good recommendations for the installation of my furnace as well as the installation of my generator. They cleaned up and left the site as they found it—it wasn't a mess at all—so I had nothing but a very positive, positive experience with the installation and the technicians. When I called for information from the office staff, they too were very professional and got me the information I needed. They deserve an A+.”

“I thought that they were very professional, and they did a great job. I had no problems whatsoever with them. They did exactly what they quoted. They were very clean inside the house and outside the house, and they didn't leave any messes around. They were very pleasant and polite and showed up on time. They replaced my heat pump outside and my air handler up in my attic. And then they also came back when I had a plumbing issue—one of the handles in my shower wouldn't turn off. They actually came on a Saturday, I think it was, so it was great. They did a good job. I would absolutely give them an A+.”

“I've dealt with John Nugent for heating and A/C. They put in a new water tank and air conditioners a few years back. As far as I know, they knew what they were doing. They did a good, clean job. I would recommend the company. Nothing went wrong. A+.”

“John Nugent & Sons cleaned and kind of did a check-up on my heating and cooling unit in my condo. The workers were extremely helpful and very nice. They did everything they could to really get the job done. I did have to call and have somebody else come back because the first guy they sent out couldn't actually do all of the job, but they were very accommodating and didn't make me pay extra for it. They were clean as they worked. The scheduling was good. I selected them because one of my other friends had used them to replace their heater in their house. I would give them an A grade.”

“John Nugent was covering for another company that I usually use—I guess those people were away—so they told me to call John Nugent, because my air conditioning went out on a hot day. The gentleman was very courteous. I was so worried I would have to replace the whole unit, and all they needed to do was refill the coolant. I felt like they were very honest and straightforward and weren't trying to sell us something I didn't need. They were clean, too. I would give them a grade of A+.”

“I've used John Nugent & Sons for heating and air. It was very positive. They were very informed and candid about the work that needed to be done, and they gave me a realistic estimate from the beginning. It was a full central air conditioning installation. I'd rate them an A.”

“John Nugent & Sons did a very nice job. They repaired a part on our heating unit, and we were very happy.”

“John Nugent & Sons had great customer service, the workers were courteous, and they were very thorough. They replaced our entire heating unit. We first heard of them through a friend who had used them. I'd give them an A.”

“I think they are good guys. I think they did heating work—a repair—for us, and they did a good job. We have a contract with them, and we have probably used them a few times. They have good attitudes, and they are very respectful of their surroundings. I think I would give them probably an A. If my friends asked, I would recommend this company.”

“The work John Nugent & Sons did was fine. I enjoyed them—they were nice people. They're doing our furnace and heater system. They get our furnace and air conditioning up to service every six months, and we're very happy with them. They take care of it. They're doing great.”

“The person who came from John Nugent & Sons was well informed, and I think he did a great job. He was the kind who says, 'This could be an issue, and that can be an issue.' He didn't exaggerate—not the kind I am especially wary of. He stuck to his job, and I think he did great work. I think it was only a Freon issue with our heater. This was the first time that we used them, and we did not go with a contract. We would definitely use them again. I think my husband's colleague told us about John Nugent & Sons. I would give them an A grade. I told my friends about them, and I said, in case they had issues, John Nugent & Sons would be the people to call.”

“They installed a new HVAC system. I selected them because I used them in the past for maintenance of my existing system and they had given some good advice. The workers were very professional, clean, and very helpful. There was no issue with getting the new system in. They get an A.”

“John Nugent & Sons came last spring. I was referred to them by somebody I really trust, and they said they were very good and just easy to deal with. They came out twice. Once, they came out to diagnose something for our heating system. They were able to troubleshoot and find out what the problem was. We chose not to take care of that problem. Then, they completed something for us—they got the heating working. They were absolutely courteous. I'd probably give them an A-.”

“John Nugent & Sons did work on my air conditioning. The quality of the work was really good. I chose them because they installed my outside unit that was here when I moved in. The technicians were fine. I would give them a positive recommendation. I would give them an A.”

“We will definitely use John Nugent & Sons again. They were responsive. While other folks who had done work for us before kept making appointments and then not showing up, John Nugent actually was here when they said they would be here. They were prompt and polite, and everything was clean. It was a job well done, and I was very pleased with them. They were fixing our furnace—the motor had gone out. I described what was going on over the phone when I made the appointment, and they asked for the model numbers and all that, and they came with exactly what they needed to fix it. It just took them a few hours to fix it. It was a quick job, and they were out of there. It is holding up well so far. I'd give them an A. It was a very positive experience. I will definitely use them again.”
