When to repair
The repair comes in under about a third of a new system's price and the unit still has years left — a furnace under 15, a boiler under 25, an AC under 12. Small parts and tune-ups almost always fall here.

How much does HVAC repair cost?
By the HVAC Service Call editorial team · Ranges cross-referenced from published 2026 cost data
All four systems were priced through the same rules, which are published in full in our methodology.
Most HVAC repairs cost $130–$2,000, averaging around $350, before any after-hours premium. What you pay depends mostly on your system — refrigerant systems run higher than forced-air heat. Know your system? Jump to its itemized page below.

02 · The comparison
Repair cost by system type
The system you have is the biggest driver of the bill — refrigerant systems run higher than forced-air heat. Each links to that system's itemized cost or repair page.
| System | Typical range | Why |
|---|---|---|
| Air conditioning | $450–$2,000 | Refrigerant work and a costly compressor push the top end up |
| Furnace | $130–$1,200 | Mostly mechanical and electrical parts — cheaper on average than refrigerant systems |
| Heat pump | $200–$2,000 | Year-round wear plus the reversing valve widen the range |
| Mini split | $150–$800 | Head-side parts are modest; the outdoor compressor is the outlier |
| Boiler | $150–$700 | Pressure and valve fixes are modest; a circulator pump or heat exchanger is not |
| Packaged unit | $450–$550 | Rooftop and all-in-one units share AC-style parts |
03 · Where the money goes
The universal bill stack and shared parts
The cost to repair HVAC equipment stacks the same way whatever the system — a service call, labour, the part, and any inspection. And several parts cost about the same across systems, because they're the same component.
| In the bill | Amount |
|---|---|
| Service call / diagnostic | $100–$250 |
| Labour | $100–$250/hr or flat-rate |
| Part (at contractor price) | varies |
| Optional inspection | $80–$450 |
| Shared part | Installed cost |
|---|---|
| Drain line clear | $75–$200 |
| Tune-up | $70–$200 |
| Capacitor | $100–$250 |
| Refrigerant recharge | $100–$500 |
| Thermostat | $150–$350 |
| Fan / blower motor | $100–$700 |
| Circuit board | $100–$600 |
| Refrigerant leak repair | $250–$1,500 |
| Ductwork repair | $500–$2,000 |
| Coils | $600–$2,400 |
| Compressor | $800–$3,000 |
One number to hold onto
The service call is the only line you pay whether or not you approve the repair. Its mechanics — what it covers, when it credits back, when it does not — are on service-call cost.
04 · Where you live
Where you live changes the number
A national range is an average of places, and nobody lives in an average. The same repair, done by an equally competent technician, costs measurably less in Alabama than in Kentucky or Tennessee — because labour, overhead and rent differ, and the part does not.
The table below applies each state's regional price parity, published annually by the US Bureau of Economic Analysis, to our national part bands. These are the same figures our city pages render, so the two can never disagree.
| Repair | National | Alabama | Kentucky | Tennessee |
|---|---|---|---|---|
| Diagnostic / service call | $75–$200 | $65–$180 | $70–$180 | $70–$185 |
| AC capacitor | $120–$400 | $105–$355 | $110–$360 | $110–$370 |
| Furnace blower motor | $300–$900 | $265–$800 | $270–$810 | $275–$825 |
| Heat-pump reversing valve | $500–$1,200 | $445–$1,065 | $450–$1,080 | $460–$1,105 |
The spread between our own three states is roughly 3%. Across the whole country it is far wider — reported state averages for the same AC repair run from about $330 in Texas and Florida to $575 in California. The lesson is not that one state is cheap; it is that a national average is the wrong tool for a decision you make locally. Our city pages carry the local band, the local licensing rule and the local utility, per metro.
05 · The costs around the repair
What else lands on the bill?
The repair is rarely the only line. Five things sit around it, and four of them are decided before the technician arrives:
| Item | Typical | What it actually is |
|---|---|---|
| Maintenance plan | $150–$500 / yr | Or $10–$30 monthly. Buys repeat visits, repair discounts and priority scheduling — worth most in the week everyone else's system fails. |
| After-hours premium | typically 1.5–2× | Where a contractor charges one. Normal-hours labour runs $75–$150 an hour; after-hours runs $140–$210. Some publish a single rate at any hour — ask. |
| Parts warranty | $0, if it holds | Commonly 10 years on parts when the unit was registered and serviced. Labour and the call-out are still yours, but a covered part is the largest line on the bill. |
| Permit | varies by city | Refrigerant and electrical work can require one. Houston, for example, publishes $46.35 plus 2% of the repair. Your contractor pulls it; you pay it. |
| Duct cleaning | $450–$1,000 | Or $25–$50 per vent. Frequently upsold during a repair visit and almost never part of one — a separate job with a separate decision. |
A tune-up sits at the top of that list for a reason: at $70–$200 it costs about what one diagnostic visit costs, and it is what produces the maintenance record a parts warranty asks for. Whether a repeat-visit plan beats paying per visit is worked through on maintenance plans.
06 · The bigger decision ✓ ✕
Repair or replace?
A repair past the two-thirds mark of a system's lifespan is where the replace question gets serious — and a major part like a compressor or heat exchanger usually settles it.
When to replace
The repair tops half the replacement price, the system is past two-thirds of its lifespan, or a compressor or heat exchanger has failed. At that point the money is better spent on a new system.

07 · Reading the quote
What does overpaying look like?
Most HVAC contractors are straight. The ones who are not rely on the same few moves, and all of them work because the homeowner is cold, rushed, and cannot price the part. Six signals worth knowing before you approve anything:
- A quote that will not itemise
- Part, labour and fee belong on separate lines. A single lump number cannot be compared to anything, which is usually the point. Ask for it in writing before work starts.
- A replacement pitch before a diagnosis
- A technician recommending a whole new system before naming the failed part is selling, not diagnosing. Ask which component failed and what it costs to fix.
- "Cracked heat exchanger" with nothing shown
- It is a genuine replace-now safety fault, which is exactly why it gets claimed falsely. Ask to see it — a camera photo or the combustion-analyser reading — and get a second opinion before condemning the furnace.
- Refrigerant topped up year after year
- A sealed system does not consume refrigerant. Repeated recharges without a leak search means you are paying annually for a leak nobody has fixed.
- Today-only pricing
- A discount that expires when the van leaves exists to stop you getting a second quote. A real price is still real tomorrow.
- No licence number offered
- Licensing is a state matter and verifiable in a public register. A contractor who will not give the number is one you cannot check.
The single most effective defence costs one diagnostic fee: on any repair over about $1,000, get a second written quote. At that size the gap between two contractors is routinely larger than the fee you pay to discover it. How to choose between them is on choosing an HVAC company, and what a normal visit should look like is on what to expect from a service call.
08 · Our numbers
Where our numbers come from
A page that compares four systems is only as honest as the fact that all four were priced the same way. Every band here is drawn from published 2026 consumer pricing — HomeGuide, Angi and Forbes Home — and a part earns a printed range only once two named sources agree on it. Where they do not, we leave the number out rather than average a guess: heat pump auxiliary heat strips have no figure on this site for exactly that reason.
All of it sits in a single file the AC, furnace, heat pump and boiler pages all read. That is deliberate. It means the blower motor band in the shared-parts table above is the same band the furnace page prints, and the comparison you came here to make is between real differences rather than between two writers' habits. State figures apply the Bureau of Economic Analysis regional price parity to that national band. Last reviewed in July 2026.
What we do not do: we do not perform the repair, we do not quote it, and we take no share of it. One call routes you to a licensed local contractor, and the price you agree to comes from the technician who sees the equipment — not from this table.
09 · Questions
Common questions
How long does each HVAC system last?
Typical lifespans: a furnace 15–30 years, a boiler 20–35, a central AC 12–20, and a heat pump 10–20 (shorter because it runs in both seasons). A repair past the two-thirds mark of that lifespan is where the replace question gets serious.
How much does it cost to repair ductwork?
Duct repairs run roughly $500–$2,000 depending on access and the extent of leaks or damage. Sealing leaky ducts often pays for itself in lower bills, while a full replacement is a larger, replacement-scale job.
How much does a heating system repair cost?
Home heating repair costs run $130–$1,200 for a furnace, $150–$700 for a boiler and $200–$2,000 for a heat pump, which wears faster because it works in both seasons. Heating sits below cooling on average for one structural reason: a furnace or boiler has no refrigerant circuit and no compressor, and those are the two lines that push an AC bill toward its top end.
Is a repair worth it on a 15-year-old system?
It depends on the cost. Under about a third of a new system's price, repair. Over half, or with a major part like a compressor or heat exchanger failing, replacement is usually the better math. Our repair-or-replace guide has the full framework.
Do maintenance contracts preserve my warranty?
Often, yes — many manufacturers require documented annual maintenance to keep the parts warranty valid, and labor is usually still owed. A contract's real value is whether the priority service and discounts outweigh the annual fee for you.
Are HVAC repair prices negotiable?
The diagnostic fee rarely is, but on larger repairs a written second opinion over $1,000 is fair game and gives you leverage. Ask for an itemized quote — that alone surfaces most of the room to negotiate.
