Tankless units heat water on demand. They last longer than tanks but need specific fixes. Prices vary by brand, unit age, and issue severity.

Hard water minerals coat the heat exchanger. Check for hard water signs in Cape Coral showers and appliances. Scale reduces efficiency, leading to early failures.

Unit age matters too. A five-year-old Rinnai or Navien might need a $200 sensor. A 10-year-old one faces $800 valve work because parts wear unevenly.

Labor starts at $100 per hour with a $150 service call fee. Tight spaces in garages or closets add time. Parts availability spikes prices for older models.
