"poor customer service. service manager insulted me, called me derogatory names while defaming my character. when all I was looking for was for someone to right a wrong. I was actually looking forward to them coming to look at my furnace and was hoping to find a trusted company but was given the complete opposite of what I expected. first no one called me with an update, I had to call, then no one showed by 5pm after I waited patiently all day during their 8-5 window. finally at 5:10 i reached out again only to be met with an after hours line that couldn't help me at all. once I spoke to SM, he insulted me, called me derogatory names and defamed my character all because I was understandably upset for being "brushed off" by everyone I had come into contact the entire day and given excuse after excuse with no solution that was going to benefit me. Customer service and professionalism are lacking 100%"

Complete kitchen and bath remodeling including plumbing and electrical. Highly experienced and certified technicians with over 20 years of field knowledge and empierce that will respect your home and delivery an amazing experience that you will remember and share with others for years to come. We can customize any project and work with any budget. You will admire and adore your new space.
"After I terminated the lease of my tenant in early 2023, I decided to do the whole house remodel before selling it because of the age of the house and TLC it needed. The original contractor I hired ended up going to jail for child abuse charges and I had to find another contractor to finish the job. I got a number of quotes and decided to go with Donna from AND Contractors, LLC. It is very difficult to come into a project that somebody else started and the quotes reflected that but Donna’s estimate was fair and I felt comfortable in my interactions with Donna. Don't let the fact that a woman runs the business fool you - she is a real tough but fair boss. She was on the job site every day! She treats her people right but also lets them know when they mess up and they respect her for it. There were many things that were not visible but needed to be redone where the original contractor messed up but it was important to Donna that the corrections be made. I am sure there must be limits but all of these corrections were accommodated without change orders. The project was completed on time and within budget. Oh, did I mention Donna is also a real estate agent? When the project was completed, she listed the house at the highest price in the history of the neighborhood. I was hoping but not expecting it so it was a pleasant surprise when she brought me a full price contract within a few days! I HIGHLY recommend AND contractors, LLC and Donna! If you want your project done right, on time and within budget, you owe it to yourself to at least have her look at your project!"

FAQs for tankless water heater installation projects in Rockville, 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.
