Tankless water heater
Repair, install, or tank-to-tankless conversion
Sample pricing — illustrative only, not an offer.
A licensed pro evaluates your tankless (on-demand) water heater need — repairing an existing unit, installing a new one, or converting from a tank. Because the answer depends on your gas line, venting, and demand, the visit is a diagnosis and firm quote.
What's included
- A licensed pro evaluating your tankless need in person: repair, new install, or tank-to-tankless conversion
- An inspection of your gas line capacity, venting, electrical, and hot-water demand
- A firm quote, since the right answer depends on your specific setup
- A common-part repair may be doable the same visit; a new install or conversion is scheduled separately
- Permits are typically required for gas and venting work and are part of the quoted scope
What to expect
Typical time on site: about 45–90 min
- The pro arrives for the $89 visit (usually 45–90 minutes)
- They inspect your gas line capacity, venting, electrical, and hot-water demand
- They give you a firm quote
- A repair may be doable the same visit; a new install or conversion is scheduled separately
- The $89 credits toward whatever work you approve
Good to know
- Book this if your tankless throws error codes, runs cold, or short-cycles; if you want to replace an old one; or if you're considering switching from a tank
- A conversion is a bigger project than swapping a tank — plan for it, not an emergency — and often needs a bigger gas line and new venting
- Tankless heaters save space and give endless hot water, but cost more up front and, in Houston's hard water, need a yearly descaling to stay under warranty
- Never a DIY job: gas sizing and venting carry a carbon-monoxide risk and require a licensed pro and a permit
How the diagnostic visit works
Tankless work varies too much to band honestly — a simple repair and a full tank-to-tankless conversion are worlds apart — so this is a diagnostic-first visit: a flat $89 to assess your setup and give a firm price, credited toward the work if you approve it. You'll never get an AI or firm number before the plumber has seen your gas, venting, and space in person.
Preview only — this does not book a real visit, and nobody is dispatched.
