"Tony is very experienced and knowledgeable about tankless hot water heaters. He has installed many in my neighborhood and we're all extremely satisfied with the installation process. and the performance of the heater. Tony came in organized and ready to start the job immediately, as you would expect from someone with a lot of experience. The heater is so much more efficient, using less energy since it's not heating 50 gallons of water all the time, so I look forward to saving money on my monthly gas bill.

"Robert and his crew were great. They were able to replace my rusty old drain pipes that had developed a hole in one pipe and replace them. The drain system works great and I appreciate the hard work and effort in just finding the parts needed for my almost 100 year old plumbing and getting the replacement parts installed quickly so I could use water again. Thank You Robert and the Facilities and Plumbing Crew!"

Albert Nahman Plumbing, Heating, and Cooling is a full service plumbing company dedicated to delivering exceptional service and warranties to the homeowner, apartment manager or building professional. We employ advanced diagnostic tools to solve your plumbing problems quickly and accurately. Our range of services include expert repairs to existing plumbing water, gas and sewage systems, copper piping, water main replacements, trenchless sewer replacements and tank or tankless water heater installations. We have been an early supporter of energy saving products such as tankless water heaters and are locally known as the tankless water heater specialist having installed and serviced all models of tankless water heaters for more than twenty years. We also have expertise in renovating existing kitchens, baths or laundries to help make your design dreams a reality or to simply upgrade your fixtures with high efficiency products.

"I used to trust Albert Nahman Plumbing. I don't anymore. The plumber who came out, Charles W said that Albert Nahman has been acquired by a larger national company. It's certainly changed for the worse. The only reason I found this out was because Charles said that whoever did the repair work under the kitchen sink did a bad job. Well, it was an Albert Nahman plumber. But that was before the company was bought out! I asked for an itemized estimate when I realized that a total of $1209.11 for a p-trap ($13 at Home Depot) and basket strainer (also cheap, unless I wanted to get fancy with a $60 one) seemed really high. He said it was too late in the day to connect me to a supervisor when I asked who I could speak to about an itemized estimate. I now realize that this was NOT a situation where I should have signed anything. Customers are in their right to get itemized receipts for work over $500. I was quoted $587 for the p-trap and installation and $621 for the basket strainer."
