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 moving heat through the ducts. Diagnosis is mostly a matter of finding where that chain breaks. In Conway 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.
Our experienced technicians diagnose a furnace the way it operates, in order, measuring each stage as it happens. That means igniter resistance, microamp flame signal, pressure switch operation under actual inducer draft, gas valve voltage, and blower and capacitor condition. Safety checks are never optional on a gas appliance: heat exchanger inspection, leak testing on the gas connections, and flue draft verification, since a hazard rarely shows itself at the thermostat. We finish by checking temperature rise against the data plate, making sure the burner and blower work together the way the manufacturer designed them to.
Conway HVAC services natural gas, propane, and electric furnaces from all major brands, 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 (501) 272-1589 for furnace repair anywhere in Conway, and an experienced technician will be on the way today.

How Much Does Furnace Repair Cost in Conway?
For most Conway homes, a furnace repair runs $150 to $600. Ignition and sensor problems are usually the least expensive, while blower motors, control boards, and heat exchangers cost more. Every furnace repair starts with a real diagnosis and a clear price.
| Repair | Typical cost | What it usually means |
|---|---|---|
| Flame sensor cleaning or replacementFurnace lights, then shuts off within seconds | $80–$250 | Furnace lights, then shuts off within seconds |
| Hot surface igniter replacementFurnace clicks and tries to start but never lights | $150–$400 | Furnace clicks and tries to start but never lights |
| Draft inducer motorLoud humming or grinding at startup, then lockout | $400–$1,000 | Startup fan fails, furnace won't fire |
| Blower motorBurners run but little or no air comes out of the vents | $400–$1,500 | No airflow, or the blower runs nonstop |
| Control boardFurnace won't respond to the thermostat | $300–$700 | Furnace won't respond to the thermostat |
| Gas valve replacementValve fails to open, so the furnace never lights | $250–$700 | Valve fails to open, so the furnace never lights |
Typical ranges for common repairs. Your exact price is quoted after diagnosis.
What Affects the Price
- The age and efficiency of the furnace, since high-efficiency models use more specialized parts
- A cracked heat exchanger, which is a safety issue and usually points to replacement
- Timing, such as a no-heat call on a cold night versus a scheduled repair
- How easy the furnace is to reach
When a repair gets expensive on an aging furnace, you'll see both options before deciding. Call (501) 272-1589 for a quote.
Warning Signs for Furnace Repair
Spotting the early warning signs gives you the chance to act before the situation spirals into something far more expensive. Here are the most common indicators that it's time to call a professional:
- Squealing or grinding from the blower compartment
- Water, rust stains, or black soot around the flue or cabinet
- The blower runs constantly but the air never warms
- Frequent on-off cycling that never reaches the thermostat setting
- The furnace clicks and glows but the burners never light
- Burners light, run a few seconds, then shut down repeatedly
- Loud booms at startup caused by delayed ignition
- A pilot or burner flame that is lazy yellow instead of crisp blue
Early Action Saves Money
What seems like a minor issue today can take out a compressor or heat exchanger tomorrow. If you notice any of these signs, contact Conway HVAC at (501) 272-1589 for a prompt inspection.

The Benefits of Professional Furnace Repair
The failure that matters most in a furnace is usually hidden. A cracked or corroded heat exchanger can let combustion gases into the airstream, and nothing about it is visible from the outside of the cabinet. Delayed ignition makes things worse, because each boom at light-off puts more stress on that metal. Add high voltage, a gas valve, and a flue to the same box, and there is little room for guesswork. Diagnosis is full of traps too. A high limit that keeps tripping could be a bad switch, or it could be doing exactly its job because a filter is clogged or the blower is dying, and replacing a good switch only hides the real 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
Our systematic workflow delivers thorough, lasting results on every job. Here's exactly how the furnace repair process unfolds:
Startup Sequence Testing
We watch the furnace's startup sequence and measure at every stage: inducer draft, pressure switch, igniter resistance, flame signal, and gas valve operation, to find exactly where it breaks.
Combustion Safety Check
On every visit, we inspect the heat exchanger, leak-test the gas connections, and confirm the flue is drafting. No furnace repair is complete until the unit is proven safe.
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.
Complete Verification
Before we head out, the furnace runs full cycles while we check temperature rise against the data plate, listen for clean, quiet ignition, and test each limit and safety control.

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
- Put in a fresh filter monthly through the heating season, the cheapest protection your furnace can get
- Clear boxes, lint, and above all chlorine-based cleaners out of the furnace area
- Put a carbon monoxide detector on every level and test them monthly
- Book a fall tune-up so weak igniters and fouled sensors are caught before the first freeze
- Keep the condensate trap and drain clear on high-efficiency units to prevent lockouts
- Pay attention when the burners light, since a boom instead of a soft whoosh calls for service
Should You DIY or Call a Pro?
Some simple checks are suitable for DIY, but most heating and cooling repairs benefit from professional tools, training, and experience. Consider the following comparison:
| Factor | DIY Attempt | Professional Service |
|---|---|---|
| Heat Exchanger | No way to see a crack from outside | Checked every time we open the unit |
| Ignition Faults | Parts swapped against a code list | Each ignition component tested |
| Gas Connections | Small leaks missed entirely | Every fitting checked with a detector |
| Limit Trips | Safety switch bypassed or swapped | The airflow fault behind the trip found |
| Airflow Match | Fan speed never checked | Rise measured and blower adjusted |
| Final Check | It lit once, call it fixed | Full cycles proven clean and safe |
