"Fred's Plumbing installed two 50-gallon hot water heaters and expansion tanks and replaced an instant hot. His people were very skilled and workmanship showed it. Best plumber I have used in many years and will continue to use Fred's Plumbing. Fred was professional and the estimate which he gave me was the actual cost. I highly recommend Fred's Plumbing in Fairfax, VA."

"When we purchased our home, we learned that the previous owners had Mermaid Water install a water treatment and purification system, as well as the hot water heater. We have never had a home with well/septic or treatment/purification system. We have had Mermaid Water come out on several occasions and each time the technicians have been extremely knowledgeable and friendly and conscientious. They have taken time to not only service our home but they have freely shared their knowledge with us and helped us better understand how the water works in our home. We always feel like we got the value for our money and then some! Brent, Matchett, Jay...have all been incredibly helpful and friendly! The few questions/concerns we've had (mostly due to our ignorance), they have always been willing to follow-up and resolve and resolution has been 110%. Also, they have an amazing customer service approach with their scheduling and notifications and immediate appointments scheduled--you always know who and when they will be at your home, and we love this extra touch!! Thank you Mermaid Water! We HIGHLY recommend!"

"This is the 2nd or 3rd time that we used Jimmy and couldn't have been more pleased. My house felt like a sauna and we were desperate for Jimmy to come over. He was extremely busy however he found time to stop by. We were told that we needed a new unit and by 3:30 the following day, we had a new unit installed. Can't get better service than that!!!"

"I can't say enough about DB's Plumbing. I called in the morning, had a return call within hours and they were at my house that night. 24 hours later, the new hot water heater was installed! Price beat all others. Duncan was professional and knew exactly what he was doing. DB Plumbing is now my GO TO PLUMBER!"

"Fantastic company. We had a water heater installed. The installer was fantastic. He was on time, professional and extremely knowledgeable. We will use them again. If I could give them 10 stars I would.."

"WT was great! Diagnosed the problem pretty quickly and fixed the issue of water pressure. Went an extra step and took samples of water. Great to have an experienced friendly person come out on a Friday afternoon which was less than 24 hours from my call."

"Had a surprise when workmen showed up unannounced the day after I signed the contract. Once we rescheduled the installation date and time, things went very smoothly. The installation of the furnace, AC, and hot water heater took less than a day. I'm very happy with the results."

"Albert and Joseph provided truly exceptional service during their visit to my home. Albert first installed my kitchen faucet and food processor, and then, both came back to install a water heater with remarkable professionalism, care, and efficiency. From the moment they arrived, they were responsive, respectful, and incredibly warm. They took the time to explain my options, helped me feel at ease, and ensured I understood why the water heater they recommended was the best choice on the market. On top of that, they went above and beyond by fixing a separate issue in my shower without hesitation. Their dedication, expertise, and kindness made the entire experience outstanding. I am deeply grateful for their work and highly recommend them."

"Jimmy and his team are experts in their field. Air Force One has installed an HVAC unit and two Mitsubishi mini splits for us at our home. We own a construction company, so we also hire Air Force One for all of our HVAC needs for our customers. They are always professional, prompt and fairly priced."
