"Great experience from start to finish. Our technician, Leo, was extremely thorough and upfront about possible solutions to our issue. He was very forthright and honest about everything that needed to be explored as he went. He even provided options for removing minimal drywall for a clean, safe replacement of the existing gas pipe. I appreciated his attention to detail to replace the line in the most clean approach with the existing structure -- not an easy task from what other competing bids were proposing. Great work from a solid company."

"The technician that came out to clear my line was very helpful and professional, but the general manager that came out the day after to do their free camera inspection was condescending and I did not enjoy talking with him. He was offended I didn't want to discuss solutions and said I only wanted free services, but they offered the free inspection with no strings, I didn't request it. It felt like he was just there to upsell services under the guise of a free inspection. WIll not be doing business with them again."

Affordable Plumbing, Rooter, and Water Heaters was established in response to a concerning industry trend. Many consumers are unaware that seemingly “local” Plumbing service providers are actually owned by Private Equity Firms or Investment Companies. As a result, prices are inflated, quality is compromised, and profit takes precedence over people in the home service sector. Service Technicians face lower wages and a lack of work-life balance. Our mission is to address these issues. We provide affordable solutions without compromising quality. We prioritize customer satisfaction and well-being, placing people at the forefront of our services. When you choose us, you can trust that fair pricing, high standards, and a supportive work environment for our technicians are our priorities. We strive for transparency, empowering customers to make informed decisions. With us, you receive excellence, integrity, and customer-centricity.

"Quick turnaround, great customer service and excellent communicators"

FAQs for tankless water heater installation projects in Mesa, AZ

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.
