Our work
A tankless install by our crew
Navien gas tankless
Wall-mounted, vented and ready for endless hot water
A tankless unit hangs on the wall, heats water only when a tap is open and needs its own vent, gas supply and condensate drain. Set up right and flushed on schedule, it can serve a home for many years.
Common tankless problems and flushing →What we do
Tankless water heater services
Repair, maintenance and new installs, all from one local crew.
Tankless repair
No hot water, water that goes cold mid-shower, a unit that will not fire or a leak under the cabinet. We find the cause and fix it, and we tell you plainly when a repair is not worth it.
Error codes
Tankless units shut themselves down and show a code when something is wrong. Call or text us the code and the model so we can come prepared.
Descaling and flushing
Hard water leaves scale inside the heat exchanger. A yearly flush clears it out, protects the unit and keeps the hot water steady.
Water softeners →Tank-to-tankless upgrades
We check your gas line, venting, condensate drain and outlet, then install a Navien unit sized for how many showers and appliances run at once.
Is tankless worth it? →Replacing an old tankless unit
When an older tankless heater is past repair, we swap it for a new Navien, handle the permit and haul the old one away.
12-month workmanship warranty
Our labor is covered for 12 months, on top of the manufacturer's warranty on the unit.
Common tankless problems we fix
No hot water or an error code. Often an ignition, flame-sensing, venting or condensate problem. Many of these are a repair, not a replacement.
Hot, then cold, then hot. Usually scale in the heat exchanger, a dirty inlet filter or a flow problem.
Low hot water pressure. Scale and clogged filters restrict flow through the unit.
Water under the unit. A leaking fitting, relief valve or condensate line. Turn the unit off and call us.
Loud or rumbling when it fires. Scale again, or a combustion problem that should be checked soon.
How a visit goes
1. Call or text. Tell us the brand, the model if you can see it, and any code on the display.
2. We diagnose it. Gas supply, venting, condensate, filters, sensors and the heat exchanger.
3. Options and a price first. Repair, flush or replace. Nothing starts until you say yes.
4. Fix, test, clean up. We run hot water at several taps before we leave.
Thinking about going tankless?
Tankless is a great fit for busy households and tight utility rooms, and a standard tank is still the better choice for some homes. We will tell you which one we would pick for your house. See our water heater replacement guide.
Questions
Tankless water heater FAQs
Do you repair tankless water heaters?
Yes. We diagnose and repair gas tankless water heaters, including error codes, ignition and flame problems, venting and condensate issues, leaks and scale buildup. Our plumbers are Navien-trained.
My tankless unit is showing an error code. What should I do?
Write down the code, then try turning the unit off and back on once. If the code comes back, call or text us with the code and the model. Many codes point to a specific part of the system, so it helps us arrive with the right parts.
How often should a tankless water heater be flushed?
About once a year in most of Hamilton County, because the water is hard. Scale on the heat exchanger makes the unit work harder and can cause overheating errors. Homes with a water softener can usually go longer between flushes.
Can you switch my tank water heater to tankless?
Yes. We check the gas line size, venting, condensate drain and electrical outlet first, because tankless units need more gas and their own vent. You get options and a price before any work starts.
What brand of tankless water heater do you install?
We install Navien gas tankless water heaters. We also handle the permit and haul away your old water heater.
Is the work guaranteed?
Yes. Our workmanship is covered for 12 months, on top of the manufacturer's warranty on the unit.
