Attic-installed equipment in a compact 350-home community straddling Teel Parkway.
Quick Answer
Frisco Tankless Water Heater Pros covers Christie Ranch in Frisco, Texas 75034. Nearly every home in this 185-acre community carries its water heater in the attic above finished living space, so conversions here are as much about eliminating a flood risk as about endless hot water. We install, repair and descale. Call (972) 430-9024.
The area
Christie Ranch is a compact community of roughly 350 homes on about 185 acres, sitting on the south side of Panther Creek Parkway with sections on both the east and west sides of Teel Parkway in northwest Frisco. It was built out between roughly 2005 and 2014, which puts the whole neighborhood in a narrow ten-year band rather than the long staggered build-out you see elsewhere in Frisco.
The housing is production construction rather than custom work: brick and stone elevations, pitched rooflines, attached garages, and floor plans running from about 2,038 to 4,586 square feet. Most homes have three or four bedrooms and two to four baths. Falcon Field Park sits adjacent to the neighborhood, and the community has its own pool and trail connections.
Because the whole subdivision was built inside a single decade by production builders working to a common spec, the mechanical layouts are remarkably consistent. That is genuinely useful. When we diagnose a Christie Ranch address we already have a strong prior on where the unit is, how the gas is run and what the venting looks like.
Local detail
The defining feature of Christie Ranch water heating is location: the original 40 or 50 gallon gas storage tank almost always sits in the attic, on a platform above finished ceilings, which was standard practice for Frisco production builders in this era. That was a reasonable decision when floor space was at a premium, but it means a tank failure drains through drywall.
Original equipment is now eleven to twenty years old. A gas storage tank in a vented North Texas attic lives a hard life, cycling through summer attic temperatures well over 130 degrees F and then winter nights near freezing. Most Christie Ranch homes have already replaced the original tank once, and a growing share are choosing to convert rather than replace like for like.
Attic installations bring their own requirements once you go tankless. The unit needs freeze protection, which on gas units means keeping the electrical supply live so the internal freeze protection heaters work, and it means the condensate line and the neutralizer cannot be left running through unconditioned space without insulation or a rerouted path. We plan the condensate route before we plan anything else in a Christie Ranch attic.
Why here: Production-era Christie Ranch homes put the tank on an attic platform above bedrooms and living space. A pan and a drain line help, but a failed tank still releases 40 to 50 gallons.
What we do: A wall-mounted tankless unit stores no water at all, which removes the failure mode entirely rather than just managing it.
Why here: Condensing units drain continuously while firing. A condensate line run through an unconditioned attic to an exterior wall can ice up during a multi-day freeze, and a blocked drain will lock the unit out.
What we do: We insulate the condensate run, slope it correctly and, wherever the framing allows, reroute it to an interior drain rather than terminating outside.
Why here: A 40,000 BTU attic tank was fine on a 1/2 inch branch. A 199,000 BTU tankless unit on that same branch will fire, then drop out under load when the supply pressure sags.
What we do: We upsize the branch to 3/4 inch and verify manifold pressure at full fire before we call the job complete.
Why here: A three-bath Christie Ranch home rarely stresses the unit, so owners do not notice a scaled heat exchanger until a cold morning when the unit cannot hold temperature at two fixtures.
What we do: Annual descaling. At Frisco's 8 to 11 grains per gallon, waiting for symptoms means you have already lost efficiency and warranty coverage.
Why here: Some Christie Ranch attic platforms were framed for the original install and never revisited, leaving decking and walkways that no longer meet a safe service standard.
What we do: We add decking and a proper service platform as part of the conversion so annual maintenance is a routine visit, not a hazard.
Services
$2,900 to $5,800 for a complete conversion in Frisco
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.
$2,600 to $5,200 installed depending on location and vent path
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.
$189-$349 per unit
Frisco water runs 8-11 grains per gallon. Calcium goes exactly where it does the most damage: the hottest surface in your heat exchanger.
$185-$850 for most leak repairs; exchanger work quoted separately
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.
$450-$2,400 for most tankless gas line upgrades
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.

The second heat exchanger in a condensing unit works by pulling the exhaust below its dew point, and the entire efficiency gain comes from the latent heat released when the water vapour in that exhaust turns back into liquid. The liquid is not a side effect to be tolerated. It is the proof the appliance is doing the thing you paid for, and it has to go somewhere every minute the burner is lit.
Published figures put condensate output in the region of one to two gallons per hour of sustained full-fire operation for an appliance in the 199,000 BTU class, varying with the specific unit and the inlet temperature. Those numbers are approximate and are given here to establish scale rather than to size anything. The scale is what matters: this is a drainage problem, not a drip.
| Scenario | Rough order of volume | Why it matters here |
|---|---|---|
| A single shower on a mild day | A fraction of a cup | Trivial, and it is why the line looks unimportant |
| A busy winter hour at high fire | On the order of a gallon or two | This is what the drain has to keep up with |
| A cold morning across a four-bath household | Several gallons across the morning | Enough to back up visibly if the line is restricted |
| A multi-day freeze with heavy demand | Continuous production, day and night | Exactly when an unheated line is most likely to ice |
Condensate moves by gravity at low pressure. It has no pump behind it, no velocity to speak of, and no ability to climb over anything. That makes the drain line the single least forgiving component in the entire installation, because every one of its failure modes is silent until the appliance shuts down.
The trap deserves a sentence of its own, because it is the item most often left out and the one whose absence is hardest to attribute. A condensing appliance moves its exhaust with a fan, under positive pressure, and the condensate outlet is connected to that same pressurised space. Without the trap the manufacturer specifies, the fan will push exhaust down the drain line instead of pushing condensate along it, which produces a line that never quite drains and an appliance whose combustion behavior is subtly wrong for reasons nobody would look for in a drain.
Where the discharge joins the building's drainage also matters. It has to arrive at an approved receptor with an air gap where one is required, so that nothing can be drawn back toward the appliance, and it should join at a point that can be inspected. A condensate line disappearing into a fitting nobody can reach is a line that will be diagnosed by symptom rather than by looking, which is the expensive way to find a blockage.
Where the appliance sits above every available drain, gravity does the work and the only design question is the route. Where it does not, or where the only drain within reach would demand a run so long that maintaining fall becomes impractical, a condensate pump collects the discharge in a small reservoir and lifts it to a point where gravity can take over again.
| Factor | Gravity | Condensate pump |
|---|---|---|
| Moving parts | None | A pump and a float switch |
| Dependence on electrical power | None | Total; no power means no discharge |
| Failure mode | Blockage or loss of fall | Pump failure or a stuck float |
| Protection available | Correct slope and insulation | An overflow switch wired to shut the burner down |
| Route flexibility | Constrained by continuous fall | Can lift, then fall to a distant receptor |
| Maintenance | Inspect and clear annually | Inspect, clean the reservoir, test the float annually |
| Preferred where | A receptor sits below the appliance | No receptor is reachable by fall alone |
Where a pump is used above finished space, its overflow switch should be wired to shut the appliance down rather than merely to sound. An alarm assumes somebody is home to hear it. An interlock assumes nothing, and it turns a pump failure into a service call instead of a ceiling repair.
Equipment installed in unconditioned space lives through an annual temperature swing that conditioned equipment never sees: well over 130F in a North Texas summer, then below freezing on winter nights. Nothing in that range is outside what a properly specified appliance tolerates, but it does change which components wear and which failures are worth anticipating.
One consequence is counterintuitive and worth stating plainly. Because a sealed combustion unit draws its combustion air from outdoors through a dedicated pipe, summer heat in the surrounding space does not feed the burner and does not degrade combustion. The heat acts on the control board, the wiring, the valve seals and the plastic in the condensate path, which is a different list of concerns from the one people expect.
The winter consequence is the more urgent one. Internal freeze protection in a gas tankless unit is electric, and it only works while the appliance is powered. A circuit shared with a switch somebody can turn off, or a receptacle that trips, disables freeze protection without disabling anything visible. We put the unit on a dedicated, unswitched circuit for that reason and we treat any shared or switched supply as a defect to be corrected, not a quirk to be noted.
An appliance that requires an annual maintenance visit needs to be reachable by a person carrying a bucket, a pump and two hoses, and it needs somewhere for that person to stand while the flush runs. Access that was adequate to set the equipment once is not the same as access that supports a service visit every year for two decades.

Yes. Frisco Tankless Water Heater Pros is based at 6960 Parkwood Blvd in Frisco 75034 and covers Christie Ranch on both sides of Teel Parkway as part of our core service area. A local crew matters here specifically because of the attic installations. Someone dispatched from a regional call center arrives without knowing that the unit is up a pull-down ladder above finished bedrooms, and shows up without the platform materials, condensate fittings or freeze protection parts the job actually needs. Call (972) 430-9024 and we will arrive equipped for the layout your street actually has.
Yes, and it is the most common configuration we install here since that is where the original tank already lives. Three things have to be handled properly. First, freeze protection: the unit must stay powered so its internal heaters can run during a hard freeze. Second, condensate: the acidic discharge from a condensing unit needs a neutralizer and an insulated or interior-routed drain that will not ice. Third, venting: PVC or polypropylene for condensing units, with a clear termination path. Done correctly, an attic tankless install is reliable and frees the platform space.
Size against temperature rise, not marketing numbers. North Texas winter inlet water sits around 50 to 55 degrees F, and a comfortable 105 degree shower means roughly a 55 degree rise. At that rise a 199,000 BTU condensing unit delivers about 5.5 to 6 GPM of genuinely usable flow. In a typical Christie Ranch floor plan that supports two simultaneous showers plus a kitchen sink. Summer performance is noticeably better because the inlet water is warmer, which is why sizing has to be done for January, not July.
Probably. Homes here were built between roughly 2005 and 2014, so original equipment is eleven to twenty years old and attic conditions shorten a storage tank's life. If your tank is original, or if the first replacement is now past the ten-year mark, you are in the window where a planned conversion costs far less than an emergency one. We inspect the tank, the gas branch, the venting path and the attic platform and give you a straight answer on whether to convert now or monitor.
