A modern furnace runs a strict startup sequence, and knowing where the sequence breaks is most of the diagnosis. The thermostat calls, the inducer motor spins up to prove draft through a pressure switch, the hot surface igniter glows, the gas valve opens, the burners light, the flame sensor confirms fire, and only then does the blower deliver heat to the house. In Wellington, FL, the failures cluster at predictable points: a flame sensor coated in oxide that can no longer prove the flame, a hot surface igniter cracked from years of thermal cycling, a pressure switch that will not close because the inducer is weak or the condensate trap on a high-efficiency model has clogged, or a control board with a burned relay. Each one stops the sequence cold, and each one mimics the others from the hallway.
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.
Conventional or condensing, gas, propane, or electric, we repair them all, across every major brand, including the traps, drains, and dual pressure switches that come with high-efficiency models. The parts most likely to fail are already stocked on the truck: igniters, flame sensors, pressure switches, capacitors, inducer assemblies, and blower motors. That is why the majority of no-heat calls end the same visit. If your furnace is down anywhere in Wellington, call (561) 652-8025 and we will get the burners lit today.

How Much Does Furnace Repair Cost in Wellington?
For most Wellington 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. Wellington 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 | Furnace lights, then shuts off within seconds |
| Hot surface igniter replacementFurnace clicks and tries to start but never lights | $150–$400 | No ignition; one of the most common winter failures |
| Draft inducer motorLoud humming or grinding at startup, then lockout | $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 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
- Timing, such as a no-heat call on a cold night versus a scheduled repair
- 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 (561) 652-8025 to get your price.
When to Call for Furnace Repair in Wellington
Spotting the early warning signs gives you the chance to act before the situation spirals into something far more expensive. Watch for these telltale signs that professional help is needed:
- Loud booms at startup caused by delayed ignition
- A fan that keeps running while the registers blow cool air
- Burners light, run a few seconds, then shut down repeatedly
- Rust streaks, soot, or water around the cabinet or flue
- The furnace clicks and glows but the burners never light
- Squealing or grinding from the blower compartment
- Yellow, wavering burner flames where they should be sharp blue
- A furnace that shuts off every few minutes before the house warms up
Don't Wait for a Total Failure
What seems like a minor issue today can take out a compressor or heat exchanger tomorrow. If you notice any of these signs, contact Wellington HVAC at (561) 652-8025 for a prompt inspection.
Your Furnace Repair Questions Answered
Why Hire a Professional for Furnace Repair?
The most serious furnace problem 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 the margin for error shrinks. 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 swapping out a working switch only hides the real fault.
At Wellington HVAC, no symptom gets treated in isolation. A meter tells us the flame signal, so we never condemn a good sensor while the real culprit, a cracked igniter or a weak gas valve, stays in place. We confirm draft at both the pressure switch and the flue, measure temperature rise against the data plate to catch airflow problems early, and leak-test every gas connection with instruments, not a guess. When we are done, the furnace has proven itself safe and correct through a full cycle, and if it is nearing the end of its useful life, you will get an honest assessment.
Our Furnace Repair Process
Every visit follows a step-by-step method refined over years of hands-on experience. Here's what you can expect when you choose Wellington HVAC:
Startup Sequence Testing
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
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.
Targeted 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.
Final Cycle Testing
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.

A little routine maintenance goes a long way toward avoiding a mid-season breakdown. Start with these practical measures our team relies on:
- Put a carbon monoxide detector on every level and test them monthly
- Replace the filter every month while the furnace is working hard, since it costs less than any other part
- Listen at light-off; clean ignition is quiet, and booming means the burners need service
- Keep storage, lint, and especially chlorine-based products away from the furnace closet
- Avoid packing the utility room, because burners need open space for combustion air
- Keep the condensate trap and drain clear on high-efficiency units to prevent lockouts
- Have the furnace checked every autumn, while a weak igniter or fouled sensor is still an easy fix
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. Here's a comparison:
| Factor | DIY Attempt | Professional Service |
|---|---|---|
| Exchanger Cracks | Cracks invisible from the outside | Inspected on every repair visit |
| Ignition Faults | Parts swapped against a code list | Every stage measured before replacing parts |
| Gas Safety | Connections judged by smell | Connections leak-tested with instruments |
| Limit Trips | Safety switch bypassed or swapped | Filter, blower, and ducts checked for the cause |
| Blower Setup | Fan speed never checked | Blower tuned to the rated rise |
| Verification | One good start and done | Clean, safe operation verified over full cycles |
