"RightNow Plumbing reliably provides competent, scrupulous, trustworthy service. Recently I engaged Andy to service our well-water acid neutralizer tank, because I questioned the reliability of service by another company 13 months earlier. Andy tested our water and found that its pH value was 6.97, which was consistent with previous readings over the past six months when he did other work for us. Because our well-water pH is essentially neutral, Andy explained the acid neutralizer tank is not necessary. He offered two options: 1) remove the tank (thus leaving us with only the water softener tank) or 2) empty it, which option I selected. He also reduced the cost of the service call. Andy’s approach starkly contrasts with the other company that for years took advantage of an unsuspecting customer by charging almost $300 to “service” the tank and unnecessarily adding expensive calcite. For competent, scrupulous, trustworthy service, call RightNow Plumbing. Posted May 14, 2025"

Advanced Environment Solutions, Inc., is dedicated to providing our customers with the best quality and craftsmanship. We are here to build relationships with our customers and communities and to provide our employees with a great place to work. Advanced Environment Solutions, Inc., is a leader in providing our customers with the highest quality products and craftsmanship in an honest, efficient, and professional way. Our pledge is to create successful relationships with our customers, employees and community by building trust, treating every project with the utmost integrity and exceeding expectations.

"From the moment I received a call from Tammy at Advanced Environment Solutions Inc. (AES), I knew I was dealing with a company that stands out from the rest. We had been shopping around for HVAC replacement quotes, and to our surprise, AES offered an over-the-phone estimate that was a staggering $7,000 less than any other quote we had received. This wasn't just a promise; it was a reality that they delivered on with professionalism and integrity. The process was seamless. After a quick confirmation visit by their technician to verify our unit size, everything was set in motion. On the day of installation, despite the sweltering heat, AES's teams worked with remarkable efficiency. One team expertly removed our old unit, and almost immediately, another arrived with the new one. The entire replacement was completed in a single day, leaving us both amazed and immensely grateful. The staff at AES were not only professional but also incredibly courteous and knowledgeable. They explained each step of the process, ensuring we understood everything. The quality of the new HVAC unit they installed surpasses any expectations we had, offering superior performance and energy efficiency. What's most puzzling and impressive is how AES manages to undercut competitors by such a significant margin while providing top-notch service and quality. This is a testament to their business model, which prioritizes customer satisfaction and ethical pricing. We highly recommend Advanced Environment Solutions Inc. to anyone in need of HVAC services. Their commitment to excellence, combined with unbeatable pricing, makes them the go-to choice. Contact AES, and like us, you'll discover why they are simply awesome!"

"I don't think it gets any better than this. The job was in a condo with a lot of rules that Chesapeake Kitchens scrupulously followed. The workmanship was excellent, and the quality of the materials used was very high. I was a first-time remodeler, and I needed lots of guidance about what would work and what wouldn't. The only mistake they made was in occasionally assuming I knew something I didn't know, but the results were always beautiful, and within budget."

"Our family home has always been clean and functional but after thirty years it had become more a picture postcard from the 1980’s than the warm inviting image we had in our mind. It was obviously time to update. Unfortunately, after talking with numerous contractors, it seemed we would have to reduce our expectations or spend more than we had budgeted to afford remodeling our “dining room, living room, kitchen” (and eventually bathrooms too!) project. While pondering our next move a family friend told us they recently had Rohan remodel their kitchen/living space and it looked great and was, they thought, affordable. After seeing for ourselves the quality of workmanship, the improvements to ‘flow and functionality’ and the overall aesthetic appeal, we decided to give Rohan a call. Boy are we glad we did! Upon meeting Rohan for the first time we were shown the same optimism, knowledge through experience, flexibility of thought and dedication to quality that would continue straight through to the end of our multi-week project. His proposal/estimate covered all our wants and needs while fitting within our budget. The job was a total re-do and from floors to walls to counters to cabinets to plumbing to electrics and all were handled by Rohan and his team with time honed skill. The work was done in a timely fashion without ever leaving us wondering where people were or what they were going to be doing each step of the way. Every eventual ‘architectural surprise’ was met with candor, budgeted creativity and a hearty “no problem!” In the end our home was transformed ergonomically, aesthetically and affordably into a beautiful space where family and friends gather in happiness and in harmony with their surroundings. If you are considering remodeling your home we urge you to give Rohan a call. Boy will you be glad you did! "

The AES Team has 15 employees with 8 trucks to provide quality Heating/Cooling & Plumbing services 24/7. The AES team is committed to hiring and retaining some of the most qualified technicians in the area, with a minimum of 10 years experience. We make training a priority for our technicians and their helpers. We keep the vans stocked with many replacement parts to get you back up and running during our first visit.

"Needed to replace a 25+ year old HVAC system in the coldest months of the year, so I contacted Advanced Environment Solutions for a bid. I worked with Tammy at AES to schedule the inspection, follow-up, etc. - a fantastic employee. Courteous, professional, and really knows her stuff when it comes to HVAC. Unfortunately, I live in a condo with a tricky indoor/outdoor HVAC set-up that ended up requiring a fairly specific indoor unit that AES did not offer, so I had to go with another company. Still I felt compelled to leave a review for AES and Tammy to highlight their professionalism and service-oriented approach. WiIll absolutely consider AES for future projects."

Tankless water heater installations FAQs

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.
