    After 20 years of being a loyal customer, I'm moving on. John Nugent & Sons has changed. A year ago, they sold me on a $600 annual maintenance plan. I had to pay in advance and then had to call to schedule them in both spring and fall. No proactive approach: just take the money and run. When they came to do the 'maintenance,' they were in and out in a matter of minutes. Despite the annual maintenance plan, my units still experienced the same regular issues (e.g. condenser capacitor, ignitor failure, etc.). Most recently, my furnace went out. The service technician proceeded to tell my wife that it was likely a bad 'safety switch' and proceeded to give us two estimates: Option 1. A $1600 estimate to replace the pressure switch, inducer motor, and ignitor, or Option 2. A $8,000 estimate for a new furnace. Calling it a safety switch was my first hint that something was off. It's a furnace. Literally everything in it is designed for safety. You can call it a safety inducer motor, a safety ignitor, a safety flame sensor, etc. Calling it a safety switch is intended to invoke fear and a desire to 'make it safe'. After taking a look at the unit, I decided to see if i could replace the pressure switch and fan inducer myself; which I did. It still did not resolve the problem, so I called them back. When the technician arrived, it was the same guy as before, only this time, he's dealing with me instead of my wife. I was incredibly nice but he's got a bad attitude and will barely even speak with me. I assume he's pissed that I have done some of my own work. He goes out on the porch to call his boss. I can only assume he's complaining that I worked on the unit. He then comes back inside and proceeds to take the unit apart, tells me his boss will call me, and then leaves... leaving the unit in pieces. About an hour later, a supervisor calls me and tells me that they're going to need to order more parts to replace the things I've already replaced, but that they don't want to work with me if I'm going to do my own work. I kindly advise that I'd like them to do whatever is needed and that I'll await the estimate. And then,... nothing. Like a ghost, they're gone. In case you're wondering how this all turned out, I was able to call another vendor referred by a friend. They came out the same day and after reassembling the unit, they found leaves in the fresh air intake pipe. An easy fix; and one that didn't require ANY new parts at all. This should have been easily addressed by any competent HVAC technician. To the owners and operators of Nugent & Sons -- I'm a fiercely loyal customer for brands that do right by me. For 20 years, you answered my call, and then something changed. Your technicians used to be helpful and friendly, but now they seem motivated by how quickly they can get out the door and whether they can upsell me in the time they're in my home. This customer is gone for good but do I hope you turn this around because a long family legacy is at stake.

    The service was Excellent! They repaired pin hole leaks in several pipes and installed a new hot water heater at a very reasonable cost. I absolutely love their embrace of technology. They have an automated phone service that allows you to make appointments after hours. It sounded very human-like. They were always on-time for each appointment and provided plumbing advice that I as a new home owner absolutely needed. They went above and beyond! I highly highly recommend their services.

    The technician came for my annual furnace service. As always, he was professional, friendly, explained what he was doing, and answered any questions I had. He also did the annual service for my whole-house humidifier and replaced the filter. I have a contract with JNS, so there was only a charge for the filter replacement on the humidifier, which is a large unit. I had a contract with a different company for over 40 years, which installed and replaced all of my heating/cooling/water heating/air cleaner/generator appliances and plumbing over those years. They were reliable for many years, but grew to be too big and maddeningly unreliable. I switched to JNS on the recommendation of a friend and have been extremely happy with them. I recommend them without hesitation!

    John Nugent is really taking customers for a ride of late. They sent a tech out to press the reset button on the water safety switch and leave and charged $95 for this after I had repeatedly reset the switch multiple times and told them that it had not solved the problem. The tech did not attempt to check anything just asked me multiple questions reset the switch, invoiced and left! Turns out the humidifier needed servicing and today it is pouring water so he has left our basement at risk of flooding and charged us for it! This company can not be trusted any more to provide the service we relied upon them for! What sort of company charges for a diagnostic visit and doesn’t even check the system?!

    I want to preference this by saying that I have never used this service, and honestly will not be now, due to the disgust that I saw over the driver of this company's van. Upon merging into a lane and attempting to assert himself into the lane, where he did not have the right away on Georgetown Pike yesterday, this driver Spewed obscenities and gave hand signals to a young driver because they decided they wanted to be let in. I am absolutely disgusted by whoever was driving this van. He appeared to be 50's and middle aged with gray/black hair. Van License number was VA tags and will gladly be provided if I am contact with photos.
