If you are not feeling the love then you are not experiencing the Higgins way. It is our aim to be sensitive to how every aspect of a remodel project effects your life. We ask these questions of every project we are undertaking: • Is this project aligned with the homeowners long-term goals as it relates to real estate values, family size etc? • Is this project economically feasible? • How do we do this in a way that minimizes impact on the homeowners daily routine? • Is it feasible for us to meet all of the homeowners expectation at this price point? • Are we dealing with issues as they arise so the homeowner knows what we know? • When the project is completely done does the homeowner feel totally taken care of?

"Higgins is a great company that has outstanding craftsmen in their employ. I've hired them for two major remodeling jobs. I will do it again if the need arises. They are friendly, knowledgeable, and skillful. Call them. You won't be disappointed!"

FAQs for tankless water heater installation projects in Saint Louis Park, MN

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.
