Heating & Furnace Repair in Fort Worth, TX

Fort Worth winters are mild right up until they aren’t. A hard freeze rolls in overnight, every heater in the county kicks on at once, and the ones that were quietly failing all fall finally give up. That’s when you find out whether your system was ready. We handle heating repair in Fort Worth — furnaces and heat pumps both — with a safety check on every call, same-day service, and a written price before we start.

Why North Texas Winters Break Heaters

The problem isn’t constant cold — it’s that your heater sits unused for eight months, then gets asked to run flat-out the moment the temperature crashes. Igniters that were fine in March fail on the first cold night. Flame sensors coated in a summer’s worth of dust shut the burner down. And because North Texas freezes arrive suddenly and hit everyone at the same time, that’s exactly when heating companies are slammed. Anyone who lived through February 2021 knows how fast “mild winter” turns into a genuine emergency.

The Heating Problems We Fix Most

• Furnace blowing cold air. Usually a failed igniter or a dirty flame sensor shutting the burner down — often a same-visit fix.
• No heat at all. A control-board fault, a bad gas valve, a tripped safety switch, or a thermostat that’s quietly died.
• Heat pump running but the house is cold. Below freezing, heat pumps lean on backup heat. If that backup isn’t engaging, that’s the fault we hunt down.
• Short cycling. The furnace lights, runs briefly, and shuts off — often a safety doing its job because something else is wrong.
• Loud bangs or a burning smell on start-up. Delayed ignition or dust burn-off — worth checking, because it can point to a real safety issue.
• Weak, cool airflow. A tired blower motor or a filter no one changed since summer choking the whole system.

Furnace Running But Not Heating? The Six Usual Causes

If the furnace is running but the air is cold — or it lights, then shuts off — it’s almost always one of six things. Here’s what each looks like, and which are safe to check yourself:

1. A dirty air filter — the most common by far. A clogged filter restricts airflow, the heat exchanger overheats, and a safety limit shuts the burners down, leaving the blower pushing cold air. Safe to DIY: replace the filter and give it twenty minutes.
2. Thermostat settings or dead batteries. A blank or frozen screen, or a thermostat set below room temperature, never calls for heat at all. Safe to DIY: set it to Heat, a few degrees above the room, and swap the batteries.
3. Gas supply or pilot light. If the gas valve is closed or an older unit’s pilot has gone out, the burners can’t light. Call a pro: we don’t recommend homeowners work on gas — and if you smell gas at all, get out first and call from outside.
4. A dirty flame sensor. The classic sign is burners that light for a few seconds then shut off, again and again. Soot on the sensor makes the furnace believe there’s no flame, so it shuts down for safety. Call a pro: a quick clean for a technician and usually a same-visit fix.
5. A clogged condensate drain. High-efficiency furnaces produce water, and when that drain line blocks, a float switch cuts the system off. Borderline: you can look for standing water, but a repeat clog needs diagnosing.
6. The blower door safety switch. A switch behind the front panel must be pressed in for the furnace to run. If a panel came off for a filter change and wasn’t reseated, it won’t start at all. Safe to DIY: make sure the panel is seated and latched.

If you’ve worked through the safe checks and there’s still no heat, that’s the point to call. Repeated lockouts, a furnace tripping its breaker, or anything gas-related is a licensed technician’s job — not a weekend project.

Get Your Heater Ready Before the First Freeze

The best heating repair is the one you avoid by testing the system before you actually need it. In October, while it’s still mild, take fifteen minutes:

• Run the heat for fifteen minutes. If it smells strongly of burning past the first few minutes, or won’t light, you have weeks to fix it instead of hours.
• Change the filter. A summer’s worth of dust chokes airflow and is a top cause of first-freeze shutdowns.
• Clear anything stacked around the furnace or the outdoor heat-pump unit — boxes, leaves, patio furniture.
• Test the thermostat on “heat” and replace its batteries.
• Listen. Grinding, banging, or repeated clicking without ignition is a call worth making now, not on the coldest night.

A fall maintenance visit does all of this and more — including the gas and carbon-monoxide safety checks you can’t do yourself.

Furnace or Heat Pump — We Handle Both

Plenty of Fort Worth homes run gas furnaces; plenty of newer ones run heat pumps that both heat and cool. They fail in different ways and need different diagnosis, and we’re trained on both. If you’ve got a heat pump, it also handles your summer cooling — so a fall heating check and a spring AC check are really the same system, looked at twice a year.

Not sure which you have? Look at the outdoor unit on a cold day. If it runs while the heat is on, you have a heat pump. If it sits idle all winter and only wakes up in summer, a furnace is doing your heating — and a gas line and flue pipe at the indoor unit confirm it.

The difference matters, because heat pumps catch people out. A heat pump moves heat instead of burning fuel, so air from the vents feels cooler than furnace air — roughly 90–95° rather than 120°. That’s normal, not a fault. Near freezing, a heat pump loses efficiency and leans on backup electric heat, which is why bills spike on the coldest days, and it runs a defrost cycle, so steam off the outdoor unit and a few minutes of cool air are expected. What isn’t normal: the house never reaching temperature, backup heat running constantly in mild weather, or the outdoor unit iced solid and not clearing. Those are the faults we hunt down.

Gas & Carbon Monoxide: When to Shut It Down

This is the part most heating pages skip, and it matters more than any repair advice here. A gas furnace burns fuel inside your home, so there are warning signs you should never work around.

If you smell gas — that sulfur or rotten-egg odour — don’t flip switches, don’t light anything, and don’t go hunting for the leak. Get everyone out of the house and call the gas company or 911 from outside. Call us after that.

Carbon monoxide is the quieter danger. It has no smell and no colour, and a cracked heat exchanger can push it straight into your air. Watch for headaches, dizziness, nausea, or flu-like symptoms that ease when you leave the house and return when you come back; soot or dark streaking around the furnace; and a burner flame burning yellow or orange instead of steady blue. If you see any of that, or a CO alarm sounds, open doors, get everyone outside, and call for help before anything else.

Every heating call we run includes a combustion and carbon-monoxide safety check. If we find a cracked heat exchanger or an unsafe gas condition, we tell you plainly and shut the system down rather than patch it. And if your home doesn’t have a working CO detector near the bedrooms, fit one before winter — it’s the cheapest safety device you’ll ever buy.

For the record, here is exactly what that combustion and carbon-monoxide safety check covers on every heating visit we run in Fort Worth, whether it is a repair call or a seasonal tune-up:

• Heat exchanger inspected for cracks, rust, or corrosion
• Carbon-monoxide reading taken at the supply air
• Gas connections and valve operation checked for leaks
• Burner flame quality and colour assessed
• Flue and venting checked for proper draft and blockages
• Safety switches and limit controls tested

What to Do If You Lose Heat in a Hard Freeze

If your heat goes out during a genuine North Texas freeze, a few steps keep your family and your home safe while help is on the way. Layer up and gather everyone into one central room to hold heat. Let faucets drip to protect pipes from freezing and bursting — a burst pipe turns a heating problem into a flooding one. If you use a space heater, keep it on a hard surface, at least three feet from anything flammable, and never run one unattended or overnight. Never use a gas stove or outdoor grill to heat the house — that’s a real carbon-monoxide risk. Then call us: our line is answered 24/7, and freeze nights are exactly when we expect to be working.

Repair or Replace Your Furnace?

Most furnace faults are worth repairing — a $250 igniter on a ten-year-old furnace is not a reason to replace it. But a cracked heat exchanger, a failed control board on an aging unit, or a furnace past 18–20 years shifts the math toward replacement, especially if it’s paired with an old AC. When you’re near that line, we show you both numbers, and if a new system is the smart move, our installation team sizes it properly.

Why Heating Calls All Spike at Once

There’s a reason it can be hard to get a heating company out during a cold snap. North Texas doesn’t get a long, steady winter — it gets sudden freezes that arrive on the same night for everyone. Every marginal furnace in the county is asked to run hard at the same moment, and the ones with a weak igniter or a dirty flame sensor all fail together. That’s why a fall check matters so much: it’s the difference between catching the fault on your schedule and joining the emergency queue on the coldest night of the year. We keep capacity for genuine emergencies, but the homeowners who booked ahead are the ones who never end up cold.

A Recent Winter Call

A family in Wedgwood woke to a house at 54° on the first hard freeze of the year — furnace running, blowing nothing but cold. Another company couldn’t come out for three days.
