Tankless water heaters are efficient and long-lasting but only if they’re properly maintained. Over time, mineral buildup, clogged filters, and system wear can reduce performance or cause premature failure. At Cellino Plumbing, Heating, Cooling & Electric, we provide professional tankless water heater maintenance to keep your unit clean, safe, and running at peak efficiency.
Our licensed technicians follow a detailed maintenance checklist tailored to your system. A standard service includes:
We work with all major tankless water heater brands and make sure your unit meets manufacturer warranty requirements.
Tankless units are designed to last 15-20 years, but without regular servicing, performance can drop and costly repairs may follow. Preventative maintenance helps:
We recommend scheduling service at least once a year but more often in hard water areas like Buffalo.
Book your annual maintenance when it works best for you. No waiting, no hassle.
We clean and flush mineral buildup, check components, and optimize performance for all major brands.
Routine service helps your unit run smoother, use less energy, and last for years to come.
Trusted across Western New York for proactive, professional service that protects your investment.
