Every time your thermostat calls for heat, the furnace works through 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 start pushing warm air into the house. Finding the step that fails is most of the job. Around Kissimmee, FL, the usual failure points are a flame sensor fouled with oxide, 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. Any one of them halts the startup, and from the hallway they all look alike.
Rather than guess, Kissimmee 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.
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 repairs finish in one trip.

How Much Does Furnace Repair Cost in Kissimmee?
Most furnace repairs in Kissimmee cost between $150 and $600. Cleaning a flame sensor is a small job; replacing a blower motor or control board is a bigger one. Kissimmee HVAC tests the system, finds the actual fault, and quotes the repair before any work begins.
| Repair | Typical cost | What it usually means |
|---|---|---|
| Flame sensor cleaning or replacementFurnace lights, then shuts off within seconds | $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 | Loud humming or grinding at startup, then lockout |
| Blower motorBurners run but little or no air comes out of the vents | $400–$1,500 | No airflow, or the blower runs nonstop |
| Control boardErratic behavior, error codes, or no response at all | $300–$700 | Furnace won't respond to the thermostat |
| 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.
What Affects 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
- Access to the furnace in attics, closets, or crawlspaces
When a repair gets expensive on an aging furnace, you'll see both options before deciding. Call (689) 334-4800 to get your price.
Warning Signs for Furnace Repair
The sooner you notice these red flags, the easier and cheaper the problem is to resolve. These are the signals our technicians see most often when a problem is underway:
- Loud booms at startup caused by delayed ignition
- A fan that keeps running while the registers blow cool air
- Squealing or grinding from the blower compartment
- Rust streaks, soot, or water around the cabinet or flue
- The furnace clicks and glows but the burners never light
- Yellow, wavering burner flames where they should be sharp blue
- Short cycling every few minutes without reaching the setpoint
- Flames that start, last a few seconds, and go out again and again
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 Kissimmee HVAC on the phone at (689) 334-4800 and we'll take a look right away.
Frequently Asked Questions About Furnace Repair
The Benefits of Professional 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.
What to Expect From Our Furnace Repair
Our systematic workflow delivers thorough, lasting results on every job. Here's a look at each step our Kissimmee HVAC team takes:
Startup Sequence Testing
We run the furnace through its startup while we measure inducer draft, pressure switch response, igniter resistance, flame signal, and gas valve operation. The goal is to pinpoint the exact step that fails.
Safety Inspection
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.
Expert Repair
The typical repair finishes 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
The last step is 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.

Call (689) 334-4800 TodayFurnace Repair Prevention Tips
Taking preventive measures can help you avoid costly heating and cooling problems down the road. Start with these practical measures our team relies on:
- 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
- Clear boxes, lint, and above all chlorine-based cleaners out of the furnace area
- Keep a working carbon monoxide alarm on every level of the home and check it each month
- Put in a fresh filter monthly through the heating season, the cheapest protection your furnace can get
- Give the furnace room to breathe, since a crowded utility space starves the burners of air
- Book a fall tune-up so weak igniters and fouled sensors are caught before the first freeze
DIY vs. Professional Furnace Repair
Online tutorials may help in a pinch, yet lasting repairs and code-compliant installations usually depend on professional methods and trained technicians. Consider the following comparison:
| Factor | DIY Attempt | Professional Service |
|---|---|---|
| Heat Exchanger | Cracks invisible from the outside | Checked every time we open the unit |
| Ignition Faults | Guesswork based on blink codes | Each ignition component tested |
| Gas Safety | Connections judged by smell | Every fitting checked with a detector |
| Limit Trips | A safety device jumpered out | Root cause of overheating corrected |
| Airflow Match | Blower speed left wherever it was | Blower tuned to the rated rise |
| Verification | Declared fixed after one flame | Complete cycles tested before we leave |
