From the hallway, a furnace that will not heat looks the same no matter what broke. Inside the cabinet, though, the sequence is strict: 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 Palm Bay 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, Palm Bay HVAC tests the sequence stage by stage. 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 the fire and the airflow are balanced as the manufacturer intended.
Palm Bay 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 a typical no-heat call ends with the house warming up. Call (321) 538-7429 for furnace repair anywhere in Palm Bay, and we can have someone out today.

How Much Does Furnace Repair Cost in Palm Bay?
The typical furnace repair in Palm Bay lands between $150 and $600. Cleaning a flame sensor is a small job; replacing a blower motor or control board is a bigger one. 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 replacementNo ignition; one of the most common winter failures | $150–$400 | Furnace clicks and tries to start but never lights |
| Draft inducer motorLoud humming or grinding at startup, then lockout | $400–$1,000 | Loud humming or grinding at startup, then lockout |
| Blower motorNo airflow, or the blower runs nonstop | $400–$1,500 | No airflow, or the blower runs nonstop |
| 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 | Igniter glows but gas never flows to the burners |
These are common price ranges, not quotes. We confirm the exact price after diagnosing your system.
What Moves the Cost Up or Down
- The age and efficiency of the furnace, since high-efficiency models use 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
If your furnace is past 15 to 20 years old or the repair is a major one, we'll give you repair and replacement prices side by side. No heat right now? Call (321) 538-7429.
When to Call for Furnace Repair in Palm Bay
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:
- A flame that burns soft and yellow rather than steady blue
- Squeals, scrapes, or grinding noises behind the blower door
- Loud booms at startup caused by delayed ignition
- Repeated shutdowns just seconds after the burners light
- Water, rust stains, or black soot around the flue or cabinet
- The blower runs constantly but the air never warms
- A furnace that shuts off every few minutes before the house warms up
- The igniter glows and clicks, yet no flame ever appears
Don't Wait for a Total Failure
Left unchecked, even a small fault or temperature swing often signals a system working its way toward a breakdown. Don't wait, get Palm Bay HVAC on the phone at (321) 538-7429 and we'll take a look right away.
Frequently Asked Questions About Furnace Repair
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. Swapping the switch in that second case removes a safety device and leaves the actual problem in place.
At Palm Bay 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, keeps causing trouble. We confirm draft at both the pressure switch and the flue, measure temperature rise against the data plate to catch airflow problems early, and test the gas side with a leak detector, 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
We work through a clear, repeatable process so nothing gets overlooked on your property. 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.
Safety Inspection
Safety is part of every repair: heat exchanger inspection, instrument leak testing on the gas side, and flue draft verification, because a furnace that runs is not the same as a furnace that runs safely.
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.
Complete 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.
Maintenance Tips for Furnace Repair
A little routine maintenance goes a long way toward avoiding a mid-season breakdown. Put these technician-approved steps to work around your property:
- Listen at light-off; clean ignition is quiet, and booming means the burners need service
- Store laundry supplies, especially chlorine products, well away from the furnace closet
- Give the furnace room to breathe, since a crowded utility space starves the burners of air
- Put a carbon monoxide detector on every level and test them monthly
- Keep the condensate trap and drain clear on high-efficiency units to prevent lockouts
- Change the filter monthly during heating season; it is the cheapest furnace part you will ever buy
- 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?
A homeowner can swap a filter with ease, but diagnosing capacitors, refrigerant charge, control boards, and error codes calls for the equipment and know-how only a pro brings. Here's a comparison:
| Factor | DIY Attempt | Professional Service |
|---|---|---|
| Heat Exchanger | No way to see a crack from outside | Examined as standard on each call |
| Ignition Problems | New igniter installed on a hunch | Every stage measured before replacing parts |
| Gas Connections | Connections judged by smell | Connections leak-tested with instruments |
| Limit Trips | Safety switch bypassed or swapped | The airflow fault behind the trip found |
| Airflow Match | Airflow assumed, not measured | Rise measured and blower adjusted |
| Final Check | It lit once, call it fixed | Full cycles proven clean and safe |
