Tankless Concepts

Awesome company, awesome installation. A forum recommendation lead me to contact Tankless Concepts to discuss an install in late January of this year. The installation was completed in early February, and even an A rating doesn't do the company justice. Impeccable customer service, responsiveness and patience in explaining and discussing the pros and cons of the different models of tankless water heaters available, the company is really a pleasure to work with. Further, as they are a local company in the Northern Virginia area, I was also very happy to be able to support an awesome local business. Their installation was flawless and I am overjoyed to finally have the tankless system I have wanted for a long time There are many reasons for choosing to install a tankless water heater and if you are considering it or even curious about them, you should do yourself a favor and speak with Tankless Concepts first.

We did have tankless water heater installed. Overall, I think was a great experience. They have individual come out and fully explain the pros and cons of tankless water heater. They are very prompt in getting scheduled. Installment didn’t have any problems. They came out and did the work a couple of months ago, two or three months ago, December. The service cost was about $3200.

Ed did the service. He also was the man who came to visit and talk about tankless water heaters with us over 2 years ago. The company does what it says, when it says, and with a level of professionalism and courtesy that is hard to beat. A tankless water heater is the way to go. Tankless Concepts is the company to work with, without reservation.

We received excellent service from Cool Breeze and will call the company again for work in the future. After our initial call, Cool Breeze was able to schedule us immediately to diagnose the problem with our Navien tankless hot water heater that provides hot water for our faucets, appliances, and whole-house heating unit. We had to wait several days for a technician to return, while a part was ordered and shipped to the Cool Breeze office. The office scheduled the repair the day after receiving the part. Ronan, the technician who completed the repair, was efficient and thorough. We are grateful to Cool Breeze for helping us restore hot water to our home and are happy we found a company we can trust to replace our previous HVAC provider who transitioned to working solely with commercial clients.

IAQ is *the* BEST. I have total peace of mind when they work on my house; I know the price is fair, the service is great, the technicians will not leave a mess, and that the business will stand behind their work. I can't recommend them highly enough!

Ronen was great. He showed up on time, explained what he was going to do before he did it, and even answered questions I had about things unrelated to my tankless water heater. He cleaned up after himself before he left and was very respectful of my home. His price to descale my tankless water heater was $50 less than an Angie's List competitor I called, so his prices are competitive. I would absolutely hire him again.

They were good, but I decided not to go with them because they were too expensive. I was impressed with the company, and I would definitely consider using them in the future.

Rod truly saved the day. From the moment he walked through the door it seemed he knew he would be able to fix my tankless issues. After being out of hot water for a few days I really appreciate his honesty and professionalism. Instead of looking to get as much money as he could out of the situation he started by trying to fix my unit instead of assuming I needed a new one. Rod did what none of the other three companies who came in did; he looked at the existing venting, water, gas, and took off the front cover of the tank.All of the other companies priced the work as if they were starting from scratch and installing and venting a whole new system. Everyone else told me my unit was fit for the trash. This company knows what they are doing with Tankless water heaters. Tankless Concepts isn't a plumbing company that dabbles in tankless water heaters. They don't try to sell you on bunch of things you don't need to get you spend more money. I will never consider working with another company when it comes to my tankless. I will forever recommend this company to anyone thinking about getting a tankless unit.

Cool Breeze saved me thousands! Our tankless hot water heating was leaking and our previous plumber said it would have to be replaced to the tune of $4,000. We called Cool Breeze for a second opinion and they came out that very day and repaired the unit for less than $400. This was months ago and our tankless is still working just fine. Plus, on top of being so incredibly quick, polite, punctual and fair, Cool Breeze also helped us renew our warranty with the hot water heater company. I could not recommend Cool Breeze more highly and I will use them for all my plumbing and A/C needs in the future.

Dario and his crew were extremely professional, and I could not be happier with the quality of work he and his people provided. I was a little wary using IAQ medics because I was not sure if they were familiar with tankless water heaters, but in the end, they provided great service. The install was seamless. I'm two months in using my water heater, and it's been a DREAM to have. I spoke with seven different contractors for the work and got quotes from three. I went with IAQ because IAQ was the most professional in presentation, and they were able to match quotes. When they did the install, the guys showed up when they said they would, worked overtime to finish the job, and cleaned up to ensure that their presence was seamless. They also have a text messaging system that will tell you who your tech is and if they are on their way. I was blown away with their professionalism. Dario, the owner, was a BREEZE to work with. Hands down, IAQ was the best contractor I have worked with so far on my fixer upper, and trust me when I say I have run the gamut on services that we needed for my home. I would hire IAQ again for any job.

I called them because my 5 year old Rinnai tankless water heater was not working and they are one of the very few Rinnai tankless water heater dealers certified to do repairs. They systematically worked through the possible problems until finding and providing a temporary fix for the problem (bad solenoid valves in plumbing not in the water heater itself). The provided a clear description of the alternatives between correcting the poor installation of my outdoor tankless water heater versus replacing it with an indoor tankless water heater. Once I decided on the replacement option, they returned within a week and installed the new heater in a single day. It's the cleanest plumbing installation I've ever seen.

I'm a DIY engineering-educated type of person, but running a long gas line and learning everything about Tankless water heaters was getting complicated - time to call the pros. I got three estimates. Rod, amazing Rinnai-recommended and certified tankless water heater installer accurately estimated and then verified all gas line and water calculations. Tankless was not the cheapest, but easily demonstrated they had the most experience and got the job done right the first time. I've had 0 issues. We just have endless hotwater and lower bills. Rod ran the gas and water lines in a way that was considerate of future expansion plans for additional faucets and gas appliances that we might install in the future. Tankless worked with Washington Gas to update the meter and worked with the inspector to make sure everything was to code. No more cold showers, carbon monoxide, wasted energy, risk of broken water tanks: 8/2014: 14.5 therms (2 adults, one kid) 8/2015: 15.6 therms (2 adults, one baby) 8/2016: 9.3 therms (2 adults, one kid, one toddler) Rod is SUCH a legendary installer that when I mentioned his name to the Washington Gas technician who upgraded the meter, the technician knew Rod by name and even came back to say hi on the day of the installation. He spoke as if ROD was the best tankless water heater installer ever - it's probably true. Additionally, Tankless, the company, was excellent and helped my secure three seperate rebate/discounts. If you need a Tankless Water heater, I strongly recommend Tankless Concepts. If you don't get a live person when you call the first time (like me), just leave a message! The first time I called I didn't get a live person and moved on to the next company I had in my priority list - but I should have left a message the first time.

Recent Review: Billy was very nice on the phone, explaining the process of installing the heater and the requirements. He provided all the details including an accurate estimate of the cost. The plumber did a very professional work, installed the heater successfully and was patient as electricians were working at the place in the same time. He also fixed a drain problem with my bath successfully.
