From the hallway, a furnace that will not heat looks the same no matter what broke. Inside the cabinet, though, everything happens in a strict order: inducer on, pressure switch closed, igniter glowing, gas valve open, burners lit, flame proven, and finally the blower sending heat through the house. Most of the diagnosis comes down to finding the broken link. In Georgetown homes, it tends to be the same handful of culprits: a flame sensor coated in oxide, a hot surface igniter cracked by thermal cycling, a pressure switch held open by a tired inducer or a plugged condensate trap, or a control board with a burned relay.
Rather than guess, Georgetown HVAC tests the sequence one stage at a time. We read igniter resistance, measure flame signal in microamps, check that the pressure switch responds to real inducer draft, confirm voltage at the gas valve, and test the blower and its capacitor. Because this is a fuel-burning appliance, the safety basics come with every visit: the heat exchanger gets inspected, gas connections get leak-tested, and draft gets verified. You cannot tell a furnace problem from a furnace hazard by looking at the thermostat. Before we leave, temperature rise is measured against the data plate so airflow and flame are matched as the manufacturer intended.
Georgetown HVAC services natural gas, propane, and electric furnaces of every major brand, from standard 80 percent units to condensing high-efficiency models with their traps, drain lines, and dual pressure switches. Our trucks carry the parts that actually fail, such as igniters, flame sensors, pressure switches, capacitors, inducer assemblies, and blower motors, so most homes have heat again before we leave. Call (737) 344-9568 for furnace repair anywhere in Georgetown, and we can have someone out today.

How Much Does Furnace Repair Cost in Georgetown?
Most furnace repairs in Georgetown cost between $150 and $600. The price depends on which part failed and how old the furnace is. You'll get a written, upfront price from Georgetown HVAC after we diagnose the problem.
| Repair | Typical cost | What it usually means |
|---|---|---|
| Flame sensor cleaning or replacementBurners light but cut out almost immediately | $80–$250 | Burners light but cut out almost immediately |
| Hot surface igniter replacementNo ignition; one of the most common winter failures | $150–$400 | Furnace clicks and tries to start but never lights |
| Draft inducer motorStartup fan fails, furnace won't fire | $400–$1,000 | Startup fan fails, furnace won't fire |
| Blower motorNo airflow, or the blower runs nonstop | $400–$1,500 | No airflow, or the blower runs nonstop |
| Control boardErratic behavior, error codes, or no response at all | $300–$700 | Erratic behavior, error codes, or no response at all |
| Gas valve replacementIgniter glows but gas never flows to the burners | $250–$700 | Valve fails to open, so the furnace never lights |
These are common price ranges, not quotes. We confirm the exact price after diagnosing your system.
What Moves the Cost Up or Down
- Furnace age and type, because 90%+ efficiency models have more specialized parts
- Whether a cracked heat exchanger is found, which usually means replacement rather than repair
- Same-day or after-hours service versus a planned visit
- Access to the furnace in attics, closets, or crawlspaces
For older furnaces facing a big repair, we'll show you what replacement would cost too, so you can compare. Call (737) 344-9568 for a quote.
When to Call for Furnace Repair in Georgetown
Spotting the early warning signs gives you the chance to act before the situation spirals into something far more expensive. These are the signals our technicians see most often when a problem is underway:
- Squealing or grinding from the blower compartment
- Short cycling every few minutes without reaching the setpoint
- A pilot or burner flame that is lazy yellow instead of crisp blue
- The furnace clicks and glows but the burners never light
- Rust streaks, soot, or water around the cabinet or flue
- Flames that start, last a few seconds, and go out again and again
- A bang or boom when the burners ignite late
- Air moving through the vents that never gets warm
Early Action Saves Money
Left unchecked, even a small fault or temperature swing often signals a system working its way toward a breakdown. Don't wait, get Georgetown HVAC on the phone at (737) 344-9568 and we'll take a look right away.

Why Hire a Professional for Furnace Repair?
A furnace combines gas, flame, high voltage, and a flue in one cabinet, and the failure that matters most is the one you cannot see from outside: a compromised heat exchanger passing combustion gases into the air your blower pushes through the house. Delayed ignition that booms at light-off stresses that exchanger further every morning it goes unfixed. Meanwhile the diagnostic traps stack up: a furnace that trips its high limit may have a bad switch, or it may be protecting itself from a clogged filter or a dying blower, and replacing the switch in the second case just removes a safety while leaving the fault.
Our experienced technicians treat every symptom as a question about the whole system. Flame signal gets measured rather than assumed, so a healthy sensor is never replaced while a cracked igniter or weak gas valve skates by. Draft is verified at the pressure switch and the flue. Temperature rise is checked against the data plate, which is how airflow problems get caught before they shorten the exchanger's life. And the gas side is leak-tested with instruments, not a sniff and a shrug. The result is a furnace that has been proven safe and correct under a full cycle, and an honest report if the unit is nearing the point where replacement beats another repair.
How Our Furnace Repair Works
We follow a proven process to ensure every repair and installation is completed to the highest standards. Here's how we handle furnace repair from start to finish:
Startup Sequence Testing
Instead of guessing, we follow the startup sequence step by step, with readings on the inducer, pressure switch, igniter, flame sensor, and gas valve, until the broken link is clear.
Combustion Safety Check
The heat exchanger is inspected, gas connections are leak-tested, and flue draft verified on every visit. A furnace repair that is not proven safe is not finished.
Same-Visit Repair
Igniters, flame sensors, pressure switches, capacitors, and motors ride on the truck, so most furnaces are lit and heating again before we pack up.
Full Verification
We finish with a full-cycle test: temperature rise matched to the data plate, smooth ignition with no booming, and every limit switch and safety control confirmed working.
Not Sure What You Need?
We provide honest advice and upfront pricing on all furnace repair work.

A little routine maintenance goes a long way toward avoiding a mid-season breakdown. Follow these tips from our experienced technicians:
- Make sure the furnace has clear combustion air; a packed utility room starves the burners
- Notice how the furnace sounds at startup, because a quiet light-off is healthy and a boom is not
- Store laundry supplies, especially chlorine products, well away from the furnace closet
- Keep a working carbon monoxide alarm on every level of the home and check it each month
- Book a fall tune-up so weak igniters and fouled sensors are caught before the first freeze
- On high-efficiency models, keep the condensate trap and drain line clear and draining
- Replace the filter every month while the furnace is working hard, since it costs less than any other part
Should You DIY or Call a Pro?
While some minor tasks like changing filters or checking a thermostat can be handled by homeowners, most HVAC work involves refrigerant, gas combustion, and high-voltage electricity, jobs that call for professional expertise. Here's a comparison:
| Factor | DIY Attempt | Professional Service |
|---|---|---|
| Heat Exchanger | No way to see a crack from outside | Inspected on every repair visit |
| Ignition Problems | Parts swapped against a code list | Igniter, sensor, and valve each metered |
| Gas Safety | Connections judged by smell | Connections leak-tested with instruments |
| High-Limit Trips | Limit replaced, cause left behind | The airflow fault behind the trip found |
| Blower Setup | Fan speed never checked | Blower tuned to the rated rise |
| Final Check | Declared fixed after one flame | Full cycles proven clean and safe |
