Installation
Installation services
$2,600 to $5,200 installed for most Frisco single-family homes
Residential Tankless Water Heater Installation
Sized against your actual fixture count and North Texas inlet water temperature, not a rule of thumb printed on a box.
$7,500 to $12,000 for a two-unit rack; $18,000 to $45,000 for larger multi-unit systems with gas infrastructure
Commercial Tankless Water Heater Installation
Rack and cascade systems designed around peak demand, health code temperatures, and the redundancy a business cannot operate without.
$2,600 to $5,500 installed, before any meter or service upgrade
Gas Tankless Water Heater Installation
The BTU rating on the box is meaningless if the pipe feeding it cannot deliver the gas. We size the fuel first.
$450 to $1,200 for point-of-use; $1,400 to $3,200 whole-house; add $2,500 to $5,000 if a service upgrade is required
Electric Tankless Water Heater Installation
No venting, no gas, no combustion air. The constraint moves to your electrical panel, and we do that math before you buy anything.
$3,500 to $5,500 for a single-unit whole-house system; $6,500 to $11,000 for a manifolded pair
Whole-House Tankless Water Heater Installation
One unit or two, sized against what your household actually runs at the same time on the coldest morning of the year.
$2,200-$4,800 installed for most Frisco replacements
Tankless Water Heater Replacement
Replacing a tankless unit that has reached the end of its life is a different job than a first-time install. We treat it that way.
Repair
Repair services
$185–$650 for most repairs; descaling from $189
Tankless Water Heater Repair
Error code on the display or no hot water at all — we diagnose the actual fault instead of guessing at parts.
$89-$189 diagnostic, credited toward the repair
Tankless Water Heater Troubleshooting
The code tells you which safety tripped. It does not tell you why. Finding out why is the whole job.
$185-$850 for most leak repairs; exchanger work quoted separately
Tankless Water Heater Leak Repair
Water under the unit means one of six things, and they range from a ten-dollar washer to a failed heat exchanger. Finding out which comes first.
$285-$950 depending on cleaning versus component replacement
Tankless Water Heater Burner Repair
A burner problem is an air-and-fuel problem. We measure both instead of cleaning the burner and hoping.
$700-$2,500 out of warranty; frequently labor-only under warranty
Tankless Water Heater Heat Exchanger Repair
The exchanger is the most expensive part in the unit and usually the most protected by warranty. We check coverage before we quote anything.
$185-$650 for most ignition repairs
Tankless Water Heater Ignition Repair
Ignition lockout is the most misdiagnosed fault in tankless service. The igniter is rarely the part that failed.
$185-$850 typical, plus a quoted after-hours premium
Emergency Tankless Water Heater Service
Gas odor, water running over a finished floor, or no hot water in a freeze. Some things do not wait until Monday.
$185-$650 for most same-day repairs at standard rates
Same-Day Tankless Water Heater Service
Standard rates, a real arrival window, and the parts that actually fail riding on the truck.
System Type
System Type services
$3,000 to $5,500 installed for most Frisco homes
Condensing Tankless Water Heater Installation
A second heat exchanger pulls latent heat out of the exhaust. That is what lets a condensing unit vent in plastic pipe and hit the mid-nineties on efficiency.
$2,400 to $4,300 installed for most Frisco homes
Non-Condensing Tankless Water Heater Installation
Fewer parts, no condensate drain and a lower price. The trade is stainless venting and about ten points of efficiency.
$2,600 to $5,200 installed depending on location and vent path
Indoor Tankless Water Heater Installation
Attic, garage wall or utility closet. Each location has a different set of code requirements, and the right one is usually not where the old tank sat.
$2,300 to $4,200 installed for most Frisco homes
Outdoor Tankless Water Heater Installation
No vent system, no combustion air calculation, no interior space consumed. The one thing that has to be planned properly is freeze protection.
$450 to $1,200 installed per fixture in Frisco
Point-of-Use Tankless Water Heater Installation
A small unit under the sink that solves one specific problem: the fixture at the far end of the house that takes a minute to get warm.
Conversion
Conversion services
$2,900 to $5,800 for a complete conversion in Frisco
Tank to Tankless Conversion
Swapping the appliance is the easy part. The gas line, the flue the furnace was sharing, and the house pressure are what make a conversion succeed or fail.
Maintenance
Maintenance services
$189-$389 for a full annual maintenance visit
Tankless Water Heater Maintenance
The annual service that keeps a 20-year unit from becoming a 9-year unit in North Texas water.
$189-$349 per unit
Tankless Water Heater Flush and Descaling
Frisco water runs 8-11 grains per gallon. Calcium goes exactly where it does the most damage: the hottest surface in your heat exchanger.
$149-$299 for a documented inspection
Tankless Water Heater Inspection
A documented condition assessment for home sales, warranty disputes, and units you inherited with the house and know nothing about.
Brands
Brands services
$2,800-$5,800 installed for most Frisco homes
Rinnai Tankless Water Heater Installation
The one major brand that still sells a full non-condensing line alongside its condensing units, which is why Rinnai fits retrofits other brands cannot.
$3,000-$6,200 installed; A-series with built-in recirculation at the higher end
Navien Tankless Water Heater Installation
A condensing-only lineup where the recirculation pump and buffer tank live inside the cabinet, which changes what the plumbing around it has to do.
$2,600-$5,400 installed residential; commercial racks quoted per system
Noritz Tankless Water Heater Installation
The lineup built specifically around replacing a tank with the least demolition, plus the commercial multi-unit systems for buildings that need serious capacity.
$2,400-$5,200 installed for most Frisco homes
Rheem Tankless Water Heater Installation
Condensing RTGH, non-condensing RTG, indoor and outdoor bodies, and EcoNet connectivity - the widest set of configuration choices in the category.
Components
Components services
$450-$2,400 for most tankless gas line upgrades
Gas Line Installation for Tankless Water Heaters
A tankless unit can demand five times the gas of the tank it replaced. The pipe that fed the tank almost never carries it, and the failure is intermittent rather than obvious.
$350-$1,800 for most tankless vent installations
Venting Installation for Tankless Water Heaters
Tankless units vent under positive pressure. That single fact rules out every B-vent flue in Frisco and decides which unit can go where.
$450-$2,200 depending on dedicated return versus crossover retrofit
Recirculation Pump Installation for Tankless Systems
A tankless unit heats instantly. The 80 feet of pipe between it and your primary bath does not. That gap is a distribution problem, and recirculation is how you solve it.
$225-$650 installed for most Frisco homes
Tankless Water Heater Expansion Tank Installation
A check valve or pressure reducing valve at the meter turns your plumbing into a closed system. Heated water has to expand somewhere, and without a tank it expands against your fixtures.
