Frequently Asked Questions
Should I repair or replace my water heater?
If your water heater is under 8 years old and the repair is minor, repair often makes sense. If it's over 10–12 years old or repairs are recurring, replacement is usually more cost-effective. We'll give you an honest assessment either way.
What are the benefits of a tankless water heater?
Tankless (on-demand) units heat water only when needed — no standby heat loss. They last 20+ years (vs. 8–12 for tank units), provide unlimited hot water, and are more energy-efficient. The upfront cost is higher but pays back over time.
My water heater is leaking — is this an emergency?
Yes, treat it as one. A leaking water heater can fail completely and flood your space. Shut off the cold water supply to the tank and call us immediately.
