"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"

"I do not recommend this company. I called them to fix an issue with my range hood exhaust. The technician charged a diagnostic fee of $95 and then said the switch was not working, which was a small component. The total charge was $391. The technician spent hardly 10 mins and charged a lot. After exhaust repaired, the house was empty for some time, and when the tenant moved in, they found that the exhaust was not working. I called the company again, and they told me that the motor was not functioning. During the first visit, the company didn't check everything; they only fixed a small component and charged a lot of money."

"STAY AWAY!!!! This Company cancelled the initial estimate on me 3 times making me drive 90 minutes to the property each time. They finally showed and gave me the typical hard sell "if you sign the contract today..." They gave us a quote so far over market value we should have walked away. But we agreed because of the "70 year history in the industry" We thought we were buying a service from a company with integrity. They took an immediate $18K deposit on a $55K project. I know, shame on me for agreeing to such an amount. We knew we were over spending, but... One month later, they simply cancelled the contract without explanation and without any work on the project. This contract was binding on us but, in their words, was not binding on them because "there's a clause in the fine print that allows them to cancel" THEY STILL HAVE OUR MONEY and I STILL NEED A ROOF Stay away from this company. No integrity No responsibility Unreliable Over priced Will take your money and keep it"

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.
