Preventative Maintenance
An annual flush and inspection keeps your tankless water heater running at peak efficiency, prevents scale-related failures, and keeps your manufacturer's warranty valid.
A Complete Annual Tune-Up
Every maintenance visit covers the full system — not just a quick flush.
Annual System Flush
Flush mineral buildup and scale from the heat exchanger — the #1 cause of reduced efficiency and early failure in Houston's hard water.
Inlet Filter Cleaning
Clean or replace the water inlet filter screens to restore proper flow rate and prevent flow sensor errors.
Burner Inspection
Inspect the burner assembly for debris, corrosion, or improper flame — ensuring safe, efficient combustion.
Venting Check
Inspect venting and exhaust for blockages, corrosion, or improper slope that can cause safety shutoffs.
Error Code Scan
Pull stored error codes and address any underlying issues before they become breakdowns.
Performance Report
Document current operating temperatures, flow rates, and system health — your record for warranty and resale purposes.
Why Annual Maintenance Matters Here
Houston sits on some of the hardest water in Texas. Calcium and magnesium deposits accumulate inside the heat exchanger every time hot water is produced — and without annual flushing, this scale acts as insulation, degrading efficiency and eventually cracking the heat exchanger.
Most manufacturers void the warranty if maintenance records can't be produced. Our written service report after every visit gives you documentation you can rely on.
Did you know?
Skipping just one annual flush in Houston can reduce your unit's efficiency by up to 15% — and skipping two or more years dramatically increases the risk of a premature heat exchanger failure that can cost $800–$1,500 to replace.
Common Questions
How often should I get my tankless water heater serviced?
We recommend an annual flush and inspection for most Houston homes. Houston has moderately hard water, which means mineral scale builds up faster than in other regions — annual maintenance keeps your unit efficient and extends its lifespan significantly.
What happens if I skip maintenance?
Scale buildup insulates the heat exchanger, forcing your unit to work harder and consume more gas. Over time this leads to reduced performance, error codes, and eventually heat exchanger failure — which can cost more to repair than the unit is worth.
How long does a maintenance visit take?
A standard annual flush and inspection typically takes 1–1.5 hours, including the descale cycle and all inspection checks.
Does maintenance extend my warranty?
Most manufacturers require documented annual maintenance to keep the warranty valid. We provide a written service report after every visit.
