"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"

"Hired Total Renovating for a major kitchen and bath remodel. I think I was most impressed by their flexibility in not just adjusting to all the surprises that come with remodeling an older home, but also adjustments to the plan as the project took shape, as well as the quality of their work. I really appreciated how diligent they were in ensuring every last concern was addressed before we concluded the project. Definitely a welcomed experience versus what I have encountered in the past."

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
Professional flushing services for tankless water heaters run about $200 per visit. This essential maintenance procedure eliminates mineral deposits from critical components, particularly the heat exchanger. While homeowners can purchase DIY flushing kits for $50 to $100, professional service offers the advantage of thorough cleaning with proper techniques. Professional maintenance also includes inspection of additional components that might need attention.
Industry experts and manufacturers recommend annual maintenance for tankless water heaters, with more frequent service (every six months) for homes with challenging water conditions. This regular attention prevents efficiency losses and extends the unit's operational lifespan. Watch for warning signs like reduced water temperature, inconsistent performance, or system error codes that might indicate maintenance is needed sooner than scheduled.
Neglecting regular maintenance allows mineral scale to accumulate within your system, restricting water flow and reducing heating efficiency. This forces your unit to work harder, consuming more energy while delivering less satisfactory performance. Over time, this strain can lead to component failures, inconsistent water temperatures, and premature system replacement. Additionally, most manufacturers require documentation of regular maintenance to honor warranty coverage for major components.
