Additional DBA - JCF Inc .

"Jimmy showed up to my home during a time when my thermostat was not working. That issue was fixed. He sold me a services contract and told me when he returned to services the units, he will cover the pipes outdoors. I purchased the contract for twice per year maintenance. I scheduled with him for a specific date. Appointment was confirmed but Jimmy did not show. When I called, he it appears that he forgot my appointment and he rescheduled saying he could not work in the rain. He rescheduled for a few days after and one of his workers showed up (Carlos). The guy showed up looking like he was someone who does not want to work and unprepared. So, I asked him if he has filters and he said know. Jimmy's workman did not bring filter, so I offered him filters I had stored. I asked him if he bought things to cover the pipes at the back, he said no. I called and left a message for Jimmy. Carlos was so rude and unprofessional. I was so scared of him and the way he was behaving. Carlos then said he would NOT do any service. IT WAS A WASTE OF MY TIME. He did return my money. BUT I will not recommend him. Will NOT use him again. As woman I will not hire again. Customer services was poor, reliability and punctuality poor."

"Our place had good bones but didn’t work for our daily life. Every room felt cut off from the next. Ben and Teddy from Top Remodeling sat with us and came up with a better layout without changing the size of the home. They moved the hallway, opened the living area, and added a custom touch in almost every room. They rebuilt the inside from the studs and used solid-core doors and clean finishes. We went with soft white walls, bronze handles, and natural maple cabinets. Now, it all feels open and calm. Every room has a purpose."

DMV Kitchen and Bath Inc is a family owned and operated Full Service General Contractor specializing in Kitchen & Bathroom Remodeling and Design/Build Services. We ensure a high quality finished product with flexible and attentive service at a competitive price. We pride ourselves on having the ability to make our clients visions come to life with great design ideas and execution. Showrooms: Chantilly, (VA) (703) 657-0997 and Gaithersburg, (MD)

"Awful, awful experience. A true nightmare. They charged tens of thousands of dollars and messed up basically every aspect of our bathroom remodel. Given multiple opportunities to fix their problems, they did not. Extremely sloppy, low quality work. The work on the bathroom was clearly done by someone who has never seen a bathroom or used one, much less built one before. The shower leaks, the tile was so crooked and bumpy it had to be ripped out twice, the radiators were badly reinstalled and dripped water down through the floors into to kitchen below, the walls and ceilings they built are not straight or square, the sink handles immediately fell off, they caused a $1000 plumbing clog and our basement to flood with sewage by flushing construction debris down our toilet. Instead of replacing pipes, they kept the old pipe which we had asked them to replace, and then tried to hide and cover it up. They would also show up unannounced and let themselves into our home on days when they had not told us they would be coming or that we were supposed to expect anyone to be in our house. So on multiple occasions I would hear an unexpected noise and I'd look over and see someone in my house who I had never seen before in my life. And every time we raised an issue to them, they either ghosted us or tried to convince us it was fine and that their work had been done correctly. I have pictures to document all of these issues. I will never let anyone from DMV enter my house again and I will tell everyone I can to never do business with this company. Scammers, liars, incompetent, I hope they go out of business."

FAQs for tankless water heater installation projects in Mount Rainier, MD

Yes, although they have a higher upfront cost compared to traditional units, tankless water heaters can be worth the investment for many homeowners. They heat water on demand, eliminating standby energy losses and leading to 24% to 34% greater energy efficiency for homes using up to 41 gallons of hot water daily. Tankless units last longer—around 20 years with proper maintenance—and require less space than traditional units. They also reduce the risk of leaks and water damage since there's no tank to corrode and fail.

Tankless water heaters, including gas-powered models, do require electricity to operate components like the ignition and control systems. This means they won't function during a power outage. If you live in an area prone to outages and want to ensure a continuous hot water supply, consider installing a battery backup system or generator to keep your tankless water heater running when the power goes out.

You should set your tankless water heater to 120 degrees Fahrenheit for optimal safety and efficiency, as recommended by the U.S. Consumer Product Safety Commission. Setting the temperature at 120 degrees prevents scalding accidents, particularly for children and the elderly, and reduces energy consumption. Temperatures above 140 degrees increase the risk of burns and promote mineral buildup, which can decrease the system's efficiency.

A 20-minute shower uses 50 to 60 gallons of water, assuming a flow rate of 2.5 to 3 gallons per minute. A typical whole-house tankless water heater can produce 4 to 8 gallons of hot water per minute, providing continuous hot water for long showers. By installing low-flow showerheads and reducing shower time, you decrease water consumption and energy costs, maximizing the efficiency of your tankless system.

With proper maintenance, a tankless water heater lasts around 20 years, significantly longer than conventional tank water heaters, which last between 8 and 12 years. Regular inspections and timely repairs can further extend its lifespan. To keep your tankless system operating efficiently, have it inspected or serviced annually and address any minor issues promptly by contacting a local tankless water heater repair service.
