Quick answer
Plumber Service TX repairs, maintains and replaces gas furnaces, electric heating and heat pump systems across Dallas–Fort Worth. Fall safety tune-ups include heat exchanger inspection — the check that catches carbon monoxide risks before heating season. No-heat calls during freezes are dispatched as emergencies: email service@plumberservicetx.com marked URGENT.
The North Texas Heating Paradox: Barely Used, Badly Needed
A DFW furnace might run 600 hours a year against the AC’s 2,500 — and that light duty is exactly the problem. Furnaces here sit idle for eight months, then get slammed to continuous duty the first hard front. First-cold-night failures are a genuine season for us: pilot and ignition faults, seized inducer motors, cracked flame sensors coated in summer dust — all discoverable in a 90-minute October tune-up, all miserable at 28°F in January.
And the stakes aren’t just comfort. The 2021 winter storm taught the metroplex that heating is life-safety infrastructure: burst pipes, unlivable homes, and a run on every heating part in Texas. The lesson we push every fall since: test your heat in October, on a mild day, when a failure is an appointment instead of a crisis.
The Safety Check That Actually Matters: Heat Exchangers and CO
A gas furnace works by burning gas inside a metal heat exchanger while house air flows around its outside — combustion gases and breathing air separated by a sheet of repeatedly heated, repeatedly stressed metal. A crack in that metal is how carbon monoxide enters living air, and it’s invisible from the thermostat: the house heats fine while the exchanger leaks. Age, short-cycling and airflow problems all accelerate cracking, and furnaces past 15 years carry real risk.
Our fall tune-up inspects the exchanger directly (camera scope where design allows), tests combustion, verifies venting draft and checks gas pressure — and if we condemn an exchanger, you get photos of the actual crack, not a scare-quote. Pair any gas appliance with low-level CO alarms on every sleeping floor; we install those too.
- Fall tune-up: burners cleaned, exchanger inspected, ignition and safeties tested, gas pressure verified, filter and airflow checked.
- No-heat emergency repair: prioritized dispatch during freezes across all DFW zones.
- Replacement done right: load-calculated sizing, correct staging, permitted and inspected — with honest guidance between furnace, heat pump and dual-fuel.
- CO protection: low-level carbon monoxide alarms installed alongside any gas heating work.
Furnace, Heat Pump or Dual-Fuel? The Texas Answer
DFW’s mild-but-spiky winters make this genuinely interesting. Gas furnaces deliver cheap, fast heat and shrug off ice storms — if the grid holds. Heat pumps heat efficiently most of the winter and pair naturally with AC replacement, but lean on expensive strip heat during hard freezes. Dual-fuel systems — heat pump primary, gas furnace backup — switch automatically to whichever is cheaper for the conditions and are increasingly our recommendation for homes replacing both halves anyway. We’ll run your actual gas and electric rates through the comparison and show you the math rather than a preference.

Heating & Furnaces — Frequently Asked Questions
My furnace won’t turn on — what should I check first?
In order: thermostat set to heat and calling (batteries too), the furnace switch (looks like a light switch near the unit — famously bumped off), the breaker, and the filter (some furnaces lock out on severe airflow restriction). If those pass, email us — ignition and sensor faults are quick professional fixes.
Why does my furnace start then shut off after a few minutes?
Short-cycling is classically a dirty flame sensor (it can’t confirm flame, so the control board kills gas — a safety working correctly), an overheating limit trip from restricted airflow, or venting/pressure-switch faults. All diagnosable; running it in that pattern stresses parts, so book promptly.
How often should a gas furnace be inspected?
Annually, every fall — and non-negotiably past ten years of age. The tune-up catches first-cold-night failures early, and the heat exchanger inspection is the carbon monoxide check no CO alarm replaces (alarms detect the leak; inspection prevents it).
Is it dangerous to run an old furnace?
Age alone isn’t the danger — an inspected, sound 18-year-old furnace is safer than a neglected 12-year-old one. The risk is the uninspected cracked heat exchanger. Past 15 years, annual direct inspection plus low-level CO alarms is the responsible pattern, and we’ll tell you honestly when replacement stops being optional.
Do heat pumps actually work in Texas winters?
Very well for most of the season — DFW’s typical winter days are ideal heat pump territory. The catch is hard freezes, where efficiency drops and strip heat takes over expensively. That’s exactly the case dual-fuel solves: heat pump economy most days, gas furnace muscle during the front.
How much does furnace replacement cost in DFW?
It scales with size, staging (single-stage, two-stage, modulating) and efficiency tier, and drops meaningfully when done alongside AC replacement as a complete system. Written flat-rate options follow a load calculation — furnaces are oversold by rule-of-thumb even more than ACs.
What’s that burning smell when I first turn on the heat?
The first run of the season burning a summer’s dust off the exchanger — normal for the first hour, gone by morning. A persistent electrical or plastic smell, or any smell paired with a CO alarm, is a shutdown-and-email-us situation.
Do you handle emergency no-heat calls during freezes?
Yes — freeze-event no-heat calls are dispatched as emergencies alongside burst pipes (they cause each other). Email service@plumberservicetx.com marked URGENT; homes with infants, elderly residents or medical needs get flagged to the front of the queue.
