Cypress Tankless Services

Our Services

Professional tankless water heater maintenance to keep your system running efficiently for years to come.

Why Regular Maintenance Matters

Tankless water heaters are built to last — but only with proper care. Mineral buildup, clogged filters, and worn ignitors quietly reduce efficiency and shorten the life of your unit.

We recommend a full service visit once a year for most homes in the Moncks Corner area. Hard water conditions in Berkeley County can accelerate scale buildup, making annual flushing especially important.

There's another reason not to skip annual service: most major manufacturers — including Rinnai, Navien, and Noritz — require documented annual maintenance to keep your warranty valid. Skipping yearly service can void your manufacturer's warranty, leaving you responsible for costly repairs that would otherwise be covered.

What's Included

Flushing & Descaling

The most important service for your tankless unit

45–60 min
Annually

Over time, calcium and magnesium minerals from your water supply build up inside the heat exchanger. This scale acts as an insulator, forcing your unit to work harder and use more energy to heat the same amount of water. Left untreated, it can permanently damage the heat exchanger — the most expensive component in your system.

What we do

  • Flush the heat exchanger with a food-grade descaling solution
  • Remove mineral deposits that reduce efficiency
  • Inspect for any signs of corrosion or damage
  • Test water flow and temperature output after service

Filter Inspection & Cleaning

Protect your unit from sediment and debris

15–20 min
Annually or as needed

Your tankless water heater has an inlet filter screen that catches sediment, rust particles, and debris before they enter the unit. A clogged filter restricts water flow, which can trigger error codes, cause inconsistent temperatures, or prevent the unit from firing at all.

What we do

  • Remove and inspect the inlet filter screen
  • Clean or replace the filter as needed
  • Check water pressure and flow rate
  • Verify no error codes are present after service

Ignitor Inspection & Cleaning

Ensure reliable hot water every time

20–30 min
Annually

The ignitor is what starts the combustion process every time you turn on a hot water tap. Carbon buildup, corrosion, or simple wear can cause ignition failures — meaning you get cold water when you expect hot. A clean, properly functioning ignitor is essential for consistent performance.

What we do

  • Inspect ignitor electrodes for wear and carbon buildup
  • Clean electrodes to restore reliable spark
  • Check ignitor gap and alignment
  • Test ignition sequence and confirm proper startup

Burner Inspection

Safe, efficient combustion for your home

20–30 min
Annually

The burner is the heart of your tankless water heater. Dust, debris, and combustion byproducts can accumulate on the burner surface over time, leading to uneven flames, reduced heating capacity, and in some cases, unsafe operating conditions. A clean burner burns more efficiently and safely.

What we do

  • Visually inspect the burner assembly for debris or damage
  • Clean burner surface and combustion chamber
  • Check flame pattern and combustion quality
  • Verify safe operation and proper venting
