Get matched with top tankless water heater installers in Potomac, MD

"Perfect! Doug is an expert Plumber that knows private water system. He removed the old equipment and installed the new. Everything is still working great. The work was done almost 13 years ago. We used all Top of the line Gould Equipment. I probably should call Doug to replace it again because breakdowns with the water system can leave you stranded."

"Excellent. Two separate teams came; one for AC and Furnace; second for Tankless hot water heater; Minor toilet repair also done at no extra charge, including a follow up service call to install new toilet flush handle, also at no charge."

"We have depended on Fred and Son for expert plumbing help for years now. Today it was Joe who did the installation, and we couldn't be happier with his work. Equally important, we appreciate how friendly, considerate, and professional he was throughout his visit. We will continue to have Fred and Joe on speed dial!"

"Very thorough. Explained things so I could make an informed decision as to which heat pump to purchase. Courteous, punctual and competitively priced."

"Kap was extremely responsive on the phone to give a quotation with a very compettive price. He arrived on time, and worked effectively to finish and do everything in a professional way. The work quality was excellent and very clean. We are realy happy with the water heater he installed."

"Mr. Rema arrived on time Sunday morning to update my water heater. He installed an expansion tank, duct work and replacing the piping to the thermostat on the water heater. He did an excellent job and took his time. Mr. Rema also went to the local hardware store twice to pick up the material that was needed. The only reason I didn't give him an A was because he quoted me a price at the beginning and then went done on the price and then tried to go back up to the original quoted price. After talking with him he decided to keep the price at the lower amount that he quoted."

"Just started working with Markool this summer and they have been fantastic! When I need service, they are so fast and every person we have interacted with has been polite, knowledgeable and personable. We unexpectedly needed to replace our system during a heat wave and they were super. So responsive and quick. I would highly recommend Markool for all of your HVAC needs!"

"Tried to push me into purchasing a new water heater and quoted me higher price based on estimate from their affiliated company (which had accidentally quoted me wrong price initially)."

"I emailed Day and Night Plumber after my old water heater started shooting water out the front panel and within 10 minutes I got a phone call from them with an appointment for an estimate with Marin. The quote was very reasonable and after I supplied the Hybrid Water Heater, Marin was able to come install it on Sunday. He was extremely knowledgeable, efficient, and hard working. He finished everything, cleaned up the area, hauled away my old water heater, and showed me how everything worked. He even gave me a military discount and 12 month warranty on labor. If you need a plumber for anything, give Day and Night Plumber a call, they will give you top notch service for a reasonable price."

"Great -- the plumber arrived within an hour or two of my husband calling and was able to locate the leak and repair it. He also found and repaired an additional issue that we did not even know we had (an attachment to our hot water heater that regulates water pressure needed replacement)."
