Frequently Asked Questions

Tankless or tank — which is right for me?

Tankless units save space and energy and provide endless hot water, but cost more upfront. We'll walk through your household's hot water usage and give you an honest recommendation.

How long does a water heater replacement take?

A standard tank swap is usually completed in 2-4 hours. Tankless conversions typically take a half day due to venting and gas line work.
