Tankless Water Heaters / Conroe, Texas
My tankless water heater stopped working, or I want to go tankless
Tankless heaters are great until one throws an error code and the hot water stops. The fix is often simpler than it looks. And if you're thinking about going tankless, it's a good upgrade in the right house, but not in every house.

What could this take?
Best case
You may not need a call.
A few tankless problems are yours to try first. Your owner's manual is a good guide.
What should I do first?
- Note the error code on the display and look it up in the owner's manual. Many codes are simple.
- Turn the unit's power off and back on once to reset it.
Call us if: The error comes back, you smell gas, the unit won't fire after a reset, or it's been more than a year since it was flushed in a hard water area.
If it needs a repair: The unit needs a flush and a filter cleaning, and it's back to full performance.
Typical case
A repair with clear options.
A flush plus a part or a settings fix, found by working through the error code.
- Flush and descale
- $299
- New installation
- $4,499–$7,999
- Replacement
- $4,499–$7,499
Exception case
It may be a bigger job.
The unit has reached the end of its life, or you're switching from a tank. A new install may need gas line, venting, or electrical work, and we'll show you what's involved first.
If it becomes project work, we'll evaluate the scope and prepare a separate quote. We'll explain that before you decide.

Everyday repairs / Catalog prices
Your options. Our prices.
There are three kinds of work here, each priced separately: flushing and descaling an existing unit, replacing a tankless unit, and a new tankless install where there wasn't one before. The tiers are about the unit and how far the install goes.
Every option is professional work. The difference is the scope: what we repair, how much we address, and what that means for you.
Flush and descale
New installation
Replacement
The plumber confirms which option fits after diagnosis. You approve the work and its price before we start. A project is scoped and quoted separately.

What might be causing it—and what will you check?
Understanding the problem
What might be behind it.
Scale buildup inside the unit
Minerals in the water coat the heat exchanger. That's the most common reason a tankless heater loses performance or shows an error, and a flush often fixes it.
A clogged inlet filter
The small filter where cold water enters can clog and cut the flow until the unit won't fire.
A gas, venting, or power issue
Tankless units need enough gas, clear venting, and power. A problem with any of them shows up as an error code or no hot water.
The unit is failing, or it's time to upgrade
An older unit with repeat failures, or a tank you want to replace with tankless.
On the visit
What we check.
- The error code history and what it points to.
- The inlet filter, water flow, and scale in the heat exchanger.
- The gas supply, venting, and power to the unit.
- For a new install, whether the gas line and venting can support tankless.
How do I decide which option is right for me?
Upfront cost versus long-term
Tankless costs more to install than a tank, but it doesn't run out of hot water and doesn't keep a full tank hot all day.
Maintenance
With hard water, tankless needs a regular flush to keep working well. Skipping it is the most common reason units fail early.
Fit for the house
Switching from a tank sometimes needs a bigger gas line or new venting. We'll tell you if that makes tankless a poor fit for your home.

I have no hot water, or my water heater is acting up
A cold shower is a rough way to start the day. Water heaters work hard every day for years, and parts wear out. Most problems come down to one part, and a repair gets you hot water again without replacing the whole unit.
Water Heater Repair
What could this take? ↗My water heater is leaking, failing, or getting old
Water on the garage floor or a heater that just can't keep up is stressful, and it always seems to happen at the worst time. Tank water heaters don't last forever. Minerals in the water wear them down from the inside, and at some point replacing the tank is simply the right move.

What could this take? ↗My water heater is popping, or it's due for a flush
A water heater that pops and rumbles, or one that doesn't seem to heat like it used to, is easy to put off. Most people never think about their water heater until it stops. In hard water, minerals settle in the tank every day, and a flush clears them out before they cause trouble.
