NPS

See above. They know boilers. The technician that came only works on boilers in DC and mostly one in older homes and businesses.

Narh Mechanical, a.k.a. NPS plumbing (THIS IS VERY CONFUSING!) are very nice on the phone, but their workers were tremendously incompetent. They werent very nice, they kept talking down to me, and the estimate included a ton of stuff that I didnt ask for and that wasnt a problem. Also, while it purported to be organized well and easy to understand, it was anything but this. My wife and I have 3 post graduate degrees between us and we couldnt figure out what they were estimating or how they arrived at their final totals. Like most plumbers, they tried to sweet talk me over the phone, but the work crew exposed their true colors. I immediately began to call other companies. AVOID NARH / NPS!

Not well. While replacing the water heater, technicians cracked the drain pan and failed to bring replacement parts leaving the water to leak onto our floor causing mold to form on our baseboards and water damage to our new wood floors. After the 4th visit in a month, we dropped them. Customer service is non existent and the dispatchers are constantly losing work orders and are generally unpleasant to talk to.

Although it took longer than I'd anticipated. Diagnosed the leaking heater and called it in to our home maintenance insurer for approval to replace the heater. Bought new heater and parts, removed old one and installed new one. Team of 2, but one did most of the replacement alone while the other was called to consult on another job. This was no easy task, the basement is no bigger than a skinny walk-in closet and houses water heater, furnace, laundry and storage and is down a narrow flight of old brick steps. There were a couple minor complications, but he stayed with it until it was finished and all connected correctly with no leaks anywhere. The only disruption to me was the hour or so the water was shut off. The reason that the job cost more than just our ''co-pay'' (fee for a service call--rest is covered by insurer) was that the supply line, valve and removal weren't covered under our contract with the insurer.
