Frequently Asked Questions

How long do water heaters last?

Traditional tank water heaters typically last 8–12 years. Tankless water heaters can last 20+ years with proper maintenance. If your unit is approaching or past these ages and requiring frequent repairs, replacement is usually more cost-effective.

Should I repair or replace my water heater?

As a general rule, if your water heater is more than 10 years old and the repair cost exceeds 50% of a new unit's price, replacement is the smarter investment. Our plumbers will give you an honest assessment.

What are the benefits of a tankless water heater?

Tankless water heaters provide endless hot water on demand, use 20–30% less energy than tank models, take up far less space, and last significantly longer. They're an excellent investment for most San Antonio homes.

How long does water heater replacement take?

A standard tank water heater replacement typically takes 2–3 hours. Tankless installations may take 3–5 hours depending on whether gas line or electrical upgrades are needed.

Why is my water heater making noise?

Popping or rumbling sounds usually indicate sediment buildup on the bottom of the tank. This reduces efficiency and can shorten the unit's life. Annual flushing can prevent this issue.
