Since our founding in 1999, the professional staff at R-Mech have been tankless water heater repair and service leaders for the Kansas City, MO area. Many area companies install tankless water heaters.

A few are Rinnai Advanced Comfort Experts (ACE) like R-Mech, but no-one has the decades of experience that we have servicing and maintaining tankless water heaters for area homeowners and businesses.

Tankless water heaters offer great efficiency and unlimited hot water in both residential and commercial applications. However they are technically advanced. Properly servicing tankless water heaters, regardless of brand, require extensive training, parts support, and years of experience.

R-Mech offers 24 /7 emergency service for all brand and models of tankless water heaters including Rinnai, Noritz, Bosch, Navien and more. Tankless water heater service problems include:

  • Scale build-up causing reduced efficiency and capacity
  • Clogged or restricted inlet filters
  • Intermittent flame failures cause by gas pressure problems
  • Block or obstructed air inlet or venting
  • Improper condensation or condensation leakage
  • Unacceptable or changes wait times for hot water
  • Variable outlet water temperatures often cased by pressure balance issues
