Every time your thermostat calls for heat, the furnace runs a fixed checklist. The inducer motor starts and proves draft by closing a pressure switch, the hot surface igniter heats up, the gas valve opens, the burners light, and the flame sensor confirms there is fire. Only after all of that does the blower begin sending warm air into the house. Finding the step that fails is most of the job. Around Orlando, FL, the usual failure points are an oxide-coated flame sensor, an igniter cracked by years of heating and cooling, a pressure switch that stays open because of a weak inducer or a clogged condensate trap on a high-efficiency unit, and control boards with burned relays. Each one halts the startup, and from the hallway they all look alike.
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. The safety checks come standard on a gas appliance: heat exchanger inspection, leak testing on the gas connections, and flue draft verification, since a hazard is not visible at the thermostat. We finish by checking temperature rise against the data plate, making sure the burner and blower are matched the way the manufacturer designed them to.
We work on gas, propane, and electric models from every major brand, both conventional 80 percent units and condensing high-efficiency models with their traps, drains, and dual pressure switches. The truck stock covers the parts that actually fail: igniters, flame sensors, pressure switches, capacitors, inducer assemblies, and blower motors, so most no-heat calls end with heat the same visit.

How Much Does Furnace Repair Cost in Orlando?
Most furnace repairs in Orlando cost between $150 and $600. Cleaning a flame sensor is a small job; replacing a blower motor or control board is a bigger one. You'll get a written, upfront price from Orlando 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 | No ignition; one of the most common winter failures |
| Draft inducer motorStartup fan fails, furnace won't fire | $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 | Burners run but little or no air comes out of the vents |
| Control boardFurnace won't respond to the thermostat | $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 |
Ranges are typical for these repairs; you get an exact quote before any work starts.
Factors That Change the Price
- Furnace age and type, because 90%+ efficiency models have 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 (689) 334-4791 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. These are the signals our technicians see most often when a problem is underway:
- The furnace clicks and glows but the burners never light
- Squealing or grinding from the blower compartment
- A fan that keeps running while the registers blow cool air
- A bang or boom when the burners ignite late
- Soot, rust, or moisture near the furnace cabinet or vent pipe
- Yellow, wavering burner flames where they should be sharp blue
- Frequent on-off cycling that never reaches the thermostat setting
- Flames that start, last a few seconds, and go out again and again
Early Action Saves Money
What seems like a minor issue today can take out a compressor or heat exchanger tomorrow. At the first hint of a problem, reach out to Orlando HVAC at (689) 334-4791 for a fast inspection.

The Benefits of Professional Furnace Repair
Gas, open flame, high voltage, and a flue all share one cabinet in a furnace, and the most dangerous failure is the one you cannot see: a damaged heat exchanger that lets combustion gases into the air the blower circulates. Every morning that delayed ignition keeps booming at startup, that exchanger takes more stress. The diagnostic side has its own pitfalls. When a furnace trips its high limit, the switch itself may be bad, or the furnace may be protecting itself from a clogged filter or a failing blower. Replacing the switch when the real issue is airflow removes a safety device and leaves the actual problem in place.
Our techs look at every symptom in the context of the whole furnace. We measure flame signal instead of assuming it, which keeps us from replacing a healthy sensor while a cracked igniter or weak gas valve goes unnoticed. Draft is confirmed at the pressure switch and at the flue. Temperature rise is checked against the data plate, catching airflow problems before they cut years off the heat exchanger. The gas side is leak-tested with instruments, never with a quick sniff. What you get is a furnace proven safe over a full cycle, plus an honest opinion if the unit is getting close to the point where replacing it beats repairing it again.
What to Expect From Our Furnace Repair
We follow a proven process to ensure every repair and installation is completed to the highest standards. Here's what you can expect when you choose Orlando HVAC:
Step-by-Step Diagnosis
Instead of guessing, we follow the startup sequence one stage at a time, with readings on the inducer, pressure switch, igniter, flame sensor, and gas valve, until the broken link is clear.
Safety Verification
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.
Targeted Repair
Most furnace repairs finish in one trip. The common failure parts, from igniters and flame sensors to pressure switches, capacitors, and motors, are stocked on the truck and ready to go.
Full Verification
Before we leave, 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 few simple habits now, like regular filter changes and seasonal tune-ups, can add years to your system's life. Put these technician-approved steps to work around your property:
- 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
- On high-efficiency models, keep the condensate trap and drain line clear and draining
- Pay attention when the burners light, since a boom instead of a soft whoosh calls for service
- Schedule service each fall to catch worn igniters and dirty sensors before cold weather arrives
- Test your CO detectors monthly and make sure each floor has one
DIY vs. Professional Furnace Repair
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 | New igniter installed on a hunch | Each ignition component tested |
| Gas Connections | Connections judged by smell | Every fitting checked with a detector |
| Limit Trips | Limit replaced, cause left behind | Filter, blower, and ducts checked for the cause |
| Airflow Match | Fan speed never checked | Blower tuned to the rated rise |
| Final Check | It lit once, call it fixed | Complete cycles tested before we leave |
