Recommended Customer Reviews
My fireplace was not working properly and Nugent and Sons came out and fixed the problem very easily with a very fair price. I would definitely use them again.
Charles H.Used John Nugent & Sons to replace my ducts in the attic, place 2 dampers to redirect air in the summer and install a home humidifier. The crew arrived on time introduced theirselves and got to work they were careful and placed drop clothes down to protect my floors. At the end of the day although not done they made sure I had heat for the night and cleaned up very well. The following day arrived again on time and went to work. At the end of the day 2 they went over everything to ensure I knew how to operate the dampers and humidifier and let see everything they had done in the attic. My house has never felt warmer and without being dry.
Glenn S.Nugent has been servicing my furnace for the past four years. This year Chung did a wholly inadequate job. He gave it a cursory once over in less than 20 minutes and did no cleaning, unlike in years past. In a call to management, Walter would not give an inch. ""The $80 does not include cleaning."" ""Chung is one of our best mechanics."" ""Never heard a complaint before."" The whole company line. No offer to make it right.
NUGENT OR HIS SONS NEVER AGAIN. As an aside, I am wondering who they think is supposed to do the cleaning? The homeowner? Or is the furnace supposed to accumulate dirt until it fails? Or does Nugent expect a payment above $80 to do a cleaning? Five stars to one in a day.
I'm in the market for a new HVAC system and I decided to call John Nugent and Sons for an estimate. My friends recommended them to me. I called and left a message on the general mailbox on Tuesday morning. I have yet to get a response from anyone.
We used Nugent in the past for HVAC and were very happy with them. So when a pipe broke and water was everywhere, we called them again. They were communicative, professional and QUICK. The employees were courteous and kept the area perfectly clean. They turned a terrible situation into a tolerable one. I couldn't be more pleased. And relieved!
Absolutely outstanding Electrical, Plumbing, and heat/A/C service. I've used these guys for all of it and they are far better than competitors for the same price. These guys are as good as it gets and I'll use them again.
Dennis D.Our favorite provider of home services, such as heating, cooling, plumbing and others. Family-owned, prompt, professional and customer-service oriented. We have been using them for over 15 years, and never dissatisfied. A little pricey, but the results are always good. They must have a good training program for their technicians because they are always very professional.
Johsiah G.I had an issue with my HVAC and they were very prompt with service. The technician was professional and knew what he was doing. I had called several other places to try to get my HVAC fixed with no luck. They were the fastest to respond and they did a great job.
Kelly L.I live in a condo with a geothermal HVAC system. The unit was not cooling correctly and I had out of town guests for the weekend. I called at 8:30 am on a Friday and spoke with a very friendly representative, who was able to answer my questions and set an appointment for that same morning. My technician Todd, arrived on time and before noon. He diagnosed the problem (a clogged condensation pipe), completed the repair and answered all of my questions. Within an hour, my unit was working properly and we were nice and cool. I will always use and recommend JNS!
Called for a broken hot water heater. Came out and said I needed to replace the gas valve for over $700 or, preferably, the whole heater for $2500. Courteous but adamant that was the problem. The price for the latter (changeout) did not match what was in the book they were using for pricing, as an FYI. They charged $95 for the call.
Despite our discomfort (cold water), got a second opinion. Second person said the system lockout code was blinking and I should replace the blower. Googled system lockout code and found lots of reasons for it. Asked second guy how I could be told to replace two different parts. He called the hot water heater manufacturer who explained 5 minute process to fix the hot water heater. Minimal cost.
Here's my question to everyone who gives them a high rating -- do you have a valid second/third opinion? Otherwise, maybe your just taken in by a smiling face.
To Nugent: 1. How am I being compensated for the dishonesty (maybe inadvertent, maybe not)? 2. How will you prevent this from it happening again?
