Furnace repair prices typically range from about $173 to $829 nationally, with many homeowners paying around $378. Most bills are built the same way: service call or diagnostic fee + labor + parts, then add after-hours charges if it’s a night or weekend call. Use the pricing breakdowns below to sanity-check any estimate in under a minute, then decide whether you need a repair visit, an inspection, or a tune-up.
Furnace repair pricing at a glance
National repair cost range
Typical furnace repair cost range: $173 to $829
National average: about $378
Service call, diagnostic, and labor costs
Flat service fee to diagnose (average): about $69
Typical HVAC hourly labor (national): $60 to $70 per hour
In Palm Beach County, it’s common to see a furnace inspection or diagnostic land around $80 to $200 depending on the company, system type, and timing. If you’d rather get a firm number for your home than guess from averages, starting with a scheduled diagnostic appointment is usually the cleanest step.
Furnace tune-up, cleaning, and maintenance costs
Basic furnace tune up cost: $79 to $89
Advanced furnace maintenance and cleaning: $138 to $178
Many homeowners end up around $100 to $300 when the visit includes a thorough checkup, cleaning, and full testing, especially on gas systems where safety verification matters. If you’re trying to prevent a breakdown instead of reacting to one, a seasonal tune-up visit is typically cheaper than an emergency repair.
Annual furnace maintenance cost
Annual furnace maintenance cost (common plan range): $150 to $500 per year, depending on what’s included (priority scheduling, discounts, extra visits, labor coverage). If you like predictable costs, comparing maintenance plan options is a simple way to stabilize your heater maintenance cost year to year.
Replacement costs for context
Replacement furnace installed (national range): $2,000 to $6,000If you’re weighing repair vs replacement, the post Furnace Price in 2026 helps frame what “starting over” can look like financially.
How a furnace repair bill adds up
Most invoices follow this formula:
Total = Diagnostic (or service call) + Labor + Parts + After-hours fees (if any)
Bill breakdown example - Service call or diagnostic: $69 on average nationally, often $80 to $200 locally depending on system and timing - Labor: typically billed hourly (often $60 to $70 nationally) or as a flat-rate task - Part: small parts can be modest, major components are not - After-hours fee: adds cost for nights, weekends, or emergency scheduling Quick reality check: if a quote includes a diagnostic, at least an hour of labor, and any part at all, it’s normal for the total to land in the low-to-mid hundreds. Big parts or after-hours timing push it toward the upper hundreds.
If you want to compare two estimates apples to apples, it helps to ask for the same structure in writing: diagnostic, labor, parts, and any after-hours add-ons. Most reputable companies will provide that, and if you need a second set of eyes you can always send the details over.
Common furnace repair costs by job or part
These are the cost items that most often drive “how much does furnace repair cost” questions.
Common repair | Typical cost range |
Replace thermostat (installation labor) | About $65 per hour for installation |
Non-programmable digital thermostat | $20 to $40 |
Programmable digital thermostat | $20 to $120 |
$100 to $250 | |
$400 to $600 (parts and labor) | |
$600 to $1,300 (parts and labor) | |
Replace capacitor | $179 to $250 (parts and labor) |
Replace control board | $600 to $1,000 |
Routine maintenance (basic) | $79 to $89 |
Routine maintenance (advanced) | $138 to $178 |
Duct cleaning | $90 to $250 |
Install replacement furnace | $2,000 to $6,000 (furnace and installation) |
Igniters and flame sensors: These are common on gas systems, and while the parts themselves are not always the most expensive, the total can still land mid-range once you add diagnosis, safe combustion checks, and repeated test cycles. If your question is “cost to service gas furnace,” remember you’re also paying for the safety verification that should come with combustion equipment.
Three mini-scenarios: low, middle, and high furnace repair prices
1) Low-cost fix: dirty flame sensor only
Typical situation: furnace tries to heat but won’t stay lit, or it cycles oddly, and cleaning the flame sensor restores normal operation.What you’re paying for: diagnostic plus a short amount of labor, usually no major parts.Where it lands: often toward the low end of the typical repair range, especially during regular hours.
2) Middle-of-the-road repair: $468 (real invoice example)
This is the most “normal” category: diagnostic, a common part replacement, cleaning, and full system testing. Real total from one of my Palm Beach County calls: $468. I’ll share what caused it and what was included later in this post so you can see exactly why it wasn’t a simple inspection but also wasn’t a major component repair.
3) Higher-cost repair: control board or blower motor
Typical situation: system won’t run correctly due to a failed major component.Common pricing anchors:
Control board: $600 to $1,000
Blower motor: $400 to $600 (single-speed) or $600 to $1,300 (variable-speed). Where it lands: often near the high end, and higher if it’s after hours.
When you’re staring at a no-heat situation, the fastest way to move from guessing to certainty is to get the diagnostic done early, even if you ultimately decide not to repair. That’s why many homeowners choose to schedule a repair visit as soon as symptoms start.
Furnace inspection, tune-up, and cleaning costs
People often search “cost for furnace inspection,” “how much does a furnace tune up cost,” and “how much does it cost to have a furnace cleaned” like they’re the same thing. They’re not.
Cost for furnace inspection
A furnace inspection is usually diagnostic plus safety checks. Pricing commonly starts with a service call fee, then you’ll see labor if troubleshooting expands. If your main goal is simply to confirm safe operation and catch problems early, a maintenance-style inspection is often the best fit.
Furnace tune up cost and furnace cleaning service cost
Tune-ups are preventative. Many are priced as basic vs advanced, with typical ranges:
Basic: $79 to $89
Advanced: $138 to $178
Ask what’s included, because “tune-up” can mean anything from a quick look to a full clean and verification. A legit visit should include a full heat-cycle test and clear notes on what was checked. If you’re trying to map your total yearly spend, the guide Annual HVAC Maintenance Cost helps you budget beyond a single visit.
Annual furnace maintenance cost and plans
If you hate surprise bills, plans can help make furnace maintenance cost predictable. Many plans fall around $150 to $500 per year, and the value usually comes from priority scheduling and discounts when a repair does pop up. If that’s appealing, it’s worth browsing Maintenance Plans before the first cold night.
After-hours and emergency pricing
Timing matters. Many companies add surcharges for nights, weekends, and emergency calls. This is a big reason furnace repair prices “feel random” to homeowners, the same repair can be a different total depending on when it happens.
If you want the most cost-controlled outcome, book the checkup before demand spikes. A quick repair-and-maintenance visit ahead of the season often costs less than an urgent no-heat call.
Repair vs replace: when the math stops working
Most furnaces last around 15 to 18 years. Replacement usually starts making sense when:
The unit is older and breaking down repeatedly
The repair approaches replacement territory
There’s a major safety concern

My Palm Beach County $468 example (what was included and why it cost what it did)
In Lake Worth Beach and the rest of Palm Beach County, heater calls don’t arrive steadily all winter. They bunch up when a cold front rolls through and a system that sat idle for months suddenly won’t fire.
One call that sticks with me was a chilly evening in Wellington. The home had a 13-year-old propane furnace tied into the central system. The thermostat called for heat, the blower ran, and the air stayed cool. The igniter was weak, the flame sensor was dirty, and there was early rust around the burner area.
Here’s what the homeowner’s total included:
Diagnostic and inspection
Flame sensor cleaning
Safety circuit testing
Gas pressure verification and venting checks
Igniter replacement
Burner-area cleaning
New filter and multiple heat-cycle tests to confirm consistent ignition
The invoice came to $468. In pricing terms, that’s a realistic middle: more than a furnace checkup cost, less than a control board or blower motor situation. If you want to reduce the odds of this kind of “first cold night” repair bill, it’s usually cheaper to have the system checked ahead of time through routine maintenance service or a maintenance plan.

Quick troubleshooting checklist before you call
Safe checks that can save an unnecessary visit:
Thermostat set to heat and above room temperature
Fresh thermostat batteries (if applicable)
Breaker not tripped
Filter not severely clogged
Vents open and unblocked
Stop and call a pro if you smell gas, suspect venting issues, or the furnace repeatedly fails to ignite. That’s especially important on gas, propane, or oil systems where safety verification is part of a proper repair.
Conclusion
Furnace repair prices aren’t guesswork once you know the formula: diagnostic + labor + parts, plus after-hours if it’s urgent. Most repairs live in the $173 to $829 range nationally, with many people near $378, while major parts like control boards and blower motors push totals higher fast. If you want fewer surprises, the cheapest move is often a pre-season inspection or tune-up, and when you do need a repair, comparing quotes line-by-line keeps the pricing honest.
