Texas Winters Are Short — Which Is Exactly Why Furnaces Fail Here
A furnace in Hood County might sit idle for eight months, then get asked to perform the morning a blue norther drops us forty degrees overnight. That long idle stretch is hard on igniters, flame sensors, and inducer motors — dust settles, spiders build in burner tubes, and the first cold snap becomes our busiest week of the winter. And as anyone who was here for the 2021 freeze remembers, heat in Texas is a safety system, not a comfort feature. If yours won't start, call (817) 555-0142 — no-heat calls go to the front of the line.
Call Us If Your Heat Is Doing Any of This
- Clicks but never lights — the classic failing igniter or dirty flame sensor.
- Lights, runs a couple minutes, shuts down. Short-cycling usually means a flame-sense, overheat, or venting problem the furnace is protecting you from.
- Blowing cold air from the vents while the thermostat calls for heat.
- A burning-dust smell that doesn't fade. The first-fire-of-the-season smell should clear within the hour; anything longer deserves a look.
- Rumbling, booming, or squealing from the cabinet — delayed ignition and belt or bearing wear, respectively.
- Thermostat climbing sluggishly or never reaching setpoint on cold days.
- Electric bills spiking during cold snaps in an all-electric home — often backup heat strips running when they shouldn't.
What a Heating Repair Visit Includes
Your tech runs the furnace through a full ignition sequence and watches what it actually does: igniter resistance, flame-sensor signal, gas pressure, temperature rise across the heat exchanger, safety switch operation, and venting. On gas and propane equipment we inspect the heat exchanger and check for carbon monoxide at the registers — every visit, not on request. Then you get the flat-rate quote in writing before anything is repaired. Most common heating repairs — igniters, flame sensors, capacitors, limit switches — are same-visit fixes off the truck.
Gas in Town, Propane in the Country, Electric on the Lake
Heating around Granbury comes in three flavors, and we work on all of them. In-town homes generally run natural gas furnaces. Out toward Tolar, Lipan, and the acreage properties, propane is the standard — same combustion principles, different pressures and orifices, plus a supply chain (your tank and supplier) that has to be part of the diagnosis; we've seen plenty of "broken furnaces" that were empty tanks with a stuck gauge. Around the lake, where gas lines never ran, all-electric homes heat with heat pumps or electric furnaces — efficient in our mild winters, but dependent on backup heat strips in hard freezes, which is where the surprise electric bills come from. Knowing which failure patterns belong to which fuel is half of a fast diagnosis.
Honest Pricing — and Honest Advice About Replacement
The diagnostic fee is quoted on the phone and applied to the repair. Igniters and sensors are inexpensive; blower motors and boards are mid-range; a cracked heat exchanger on an aging furnace is replacement territory, and we'll show you the crack on camera rather than ask you to take our word for it. Because winters here are short, a furnace that limps can often wait for a planned replacement instead of an emergency one — when that's the truth, we'll say so, and you can plan the spend on your schedule instead of the weather's.
Frequently Asked Questions
My furnace clicks but never lights — what's wrong?
Usually a failing hot-surface igniter, a dirty flame sensor, or a gas-supply issue. On propane systems, an empty or low tank is worth checking before you call — it happens to everyone at least once. All three furnace-side causes are quick, inexpensive repairs when caught early.
Do you work on propane furnaces?
Yes — a large share of rural Hood County heats with propane, and we service and repair propane furnaces routinely, including coordination with your propane supplier when the problem is on the supply side.
Is a cracked heat exchanger really dangerous?
Yes. A cracked heat exchanger can let combustion gases, including carbon monoxide, into your home's air. If we find one we'll show it to you — photos, not just claims — and the furnace shouldn't run until it's repaired or replaced. Put CO detectors in any home with gas or propane heat.
Why does my electric heat make the bill explode in a cold snap?
If you have a heat pump, freezing weather can push it onto backup resistance strips, which cost roughly three times as much to run. If the strips are running when they shouldn't — a stuck sequencer or thermostat misconfiguration — a repair visit pays for itself in one billing cycle.
