AC repair costs $150 to $650 on average nationwide, according to pricing data from multiple home services sites in 2026. The full range runs wider than that single number suggests: a clogged drain line might run $100, while a failed compressor can climb past $2,800.
The part matters, but so does something most repair-cost guides skip entirely: which refrigerant your system uses. A leak repair on an older R-22 unit can cost three or four times as much as the identical repair on a newer R-410A system, purely because of refrigerant pricing.
This guide breaks down real 2026 costs by repair type, explains why refrigerant type has become the biggest hidden cost driver, and walks through when repair stops making financial sense.
AC repair cost at a glance
| Repair size | Typical cost | Examples |
|---|---|---|
| Minor | $100 to $300 | capacitor, thermostat, drain line cleaning |
| Moderate | $400 to $1,000 | fan motor, circuit board, refrigerant recharge |
| Major | $1,000 to $2,800+ | compressor, evaporator coil, large refrigerant leak |
Most homeowners land somewhere in the $250 to $650 range for a single repair, with a national average around $375.
That average comes from thousands of individual repair tickets, and most of them are dominated by the same handful of parts: capacitors, drain lines, and thermostats.
What the average number hides
A $375 average doesn’t mean most people pay $375. It means the low-cost, high-frequency repairs (capacitors, drain lines) pull the average down, while a smaller number of expensive repairs (compressors, coils) pull it back up.
If your quote comes in well above the average, it’s worth understanding what’s actually in that number before assuming you’re being overcharged.
A typical repair bill breaks into three pieces:
| Line item | Typical amount | Notes |
|---|---|---|
| Diagnostic or service call fee | $75 to $150 | Often credited toward the repair if you approve the work |
| Labor | $75 to $200 per hour | Most repairs take one to one and a half hours |
| Parts | Varies by component | Ranges from $15 for a capacitor to $800+ for a compressor |
A common $375 ticket breaks down roughly as $100 for the diagnostic visit, $150 for labor, and $125 for parts. If your quote is much higher than that, ask the technician to itemize it.
A legitimate high quote usually traces to one of three things: a major part (compressor, coil), an emergency or after-hours call, or a refrigerant type that’s become expensive to source. If none of those apply and the technician can’t explain the gap, get a second quote before approving the work.
How to read this guide by your situation
If your AC is down right now and the house is hot, skip to the “AC repair cost by type of repair” table below, match your symptoms to a repair category, and use that range to sanity-check whatever quote you get.
If you’re planning, whether your unit is older or has been acting up, the “repair or replace” section further down will matter more than any single repair price.

AC repair cost by type of repair
The specific part that failed sets the price more than anything else. Here’s what the most common AC repairs cost in 2026, based on current pricing from national cost-tracking sources.
| Repair | Typical cost |
|---|---|
| Drain line cleaning | $75 to $250 |
| Capacitor replacement | $100 to $400 |
| Thermostat replacement | $60 to $440 |
| Fan motor replacement | $300 to $700 |
| Circuit board replacement | $400 to $1,200 |
| Refrigerant leak detection and repair | $200 to $1,600 |
| Compressor replacement | $800 to $2,800 |
| Evaporator coil replacement | $1,000 to $2,500 in warranty; $2,500 to $4,500 out of warranty |
Capacitor, thermostat, and drain line (minor repairs)
For a deeper look at pricing by capacitor type, see the AC capacitor replacement cost guide. These are the repairs most homeowners will run into at some point.
- A capacitor replacement runs $100 to $400 for parts and labor, and it’s usually a fast fix since the part itself only costs $15 to $80.
- A clogged drain line often causes water leaks or a system shutdown, and cleaning it typically costs $75 to $250 depending on how accessible the line is.
- A thermostat replacement costs $60 to $440, with smart thermostats sitting at the higher end of that range.
- These repairs are almost always worth doing immediately, since a failed capacitor or clogged line can strain other components if it’s left unaddressed.
Fan motor, circuit board, and blower (moderate repairs)
- A condenser fan motor replacement costs $300 to $700; this is the fan that cools the outdoor unit, and when it fails the whole system can stop cooling.
- A circuit board replacement runs $400 to $1,200, since the board manages communication between the thermostat, compressor, and fan.
- A blower repair can cost as little as $150 for a simple fix, but a full blower replacement often runs $800 to $2,000.
- These repairs are worth approving in most cases, since a failed fan motor or blower usually means zero cooling rather than reduced performance.
Compressor, evaporator coil, and refrigerant leaks (major repairs)
For a detailed breakdown by leak size and location, see refrigerant leak repair costs by leak size.
- A compressor replacement costs $800 to $2,800, and the compressor is the most expensive single component in most AC systems.
- An evaporator coil replacement runs $1,000 to $2,500 if the part is still under warranty, or $2,500 to $4,500 if it isn’t.
- Refrigerant leak detection and repair costs $200 to $1,600, and the price depends heavily on where the leak is and how much refrigerant needs replacing.
- These are the repairs where the repair-versus-replace math matters most, which is covered further down.
Why your refrigerant type changes the price
Two identical repairs, same part, same labor time, can cost dramatically different amounts depending on which refrigerant a system uses.
This is the single biggest cost variable that generic repair-cost guides leave out, and it’s become more important in 2026 as both major refrigerant types have gotten more expensive.
How to check which refrigerant your AC uses
- Look at the nameplate on the outdoor condenser unit. Manufacturers list the refrigerant type directly on the label, usually as “R-22,” “R-410A,” or a newer designation like “R-454B.”
- Check the age of your system. Units installed before 2010 almost always use R-22, since manufacturers stopped building new R-22 equipment after that year.
- Ask your technician during any service visit. If they mention refrigerant type without you asking, that’s often a sign it’s already a cost factor in your system.
R-22 (Freon) repair costs in 2026
R-22, commonly known as Freon, was banned from new production and import in the United States in 2020 under the Clean Air Act, and prices have climbed steadily since. Read more in our R-22 phase-out and what it means for your system guide for the full regulatory timeline.
In 2026, R-22 costs an estimated $150 to $300 per pound, up from roughly $90 to $250 per pound in 2025. A full system recharge, including labor, can run $750 to $4,500 depending on how many pounds the system needs.
Homeowners aren’t legally required to replace a working R-22 system, but a repair that requires adding refrigerant becomes expensive fast: even a modest 5-pound top-up can add $500 to $1,000 in material cost alone, before labor.
R-410A and the shift to A2L refrigerants (R-454B, R-32)
R-410A replaced R-22 as the residential standard starting in 2010, and for over a decade it was the “safe” choice. That’s changing. The EPA’s AIM Act, signed in 2020, requires a phasedown of high-global-warming-potential refrigerants, and R-410A (with a global warming potential of 2,088) is one of the primary targets.
As of mid-2026, R-410A runs $80 to $150 per pound installed, up from roughly $40 to $70 per pound in 2022 to 2023. A standard 3-ton system holds 6 to 12 pounds of refrigerant, so a full recharge can cost $500 to $1,500.
Manufacturers are shifting new equipment toward A2L refrigerants like R-454B and R-32, which have lower global warming potential, and existing R-410A systems will likely see continued price increases as that transition progresses.
If your AC needs a refrigerant top-up and you’re not sure which type it uses, that’s the first question worth asking before agreeing to any recharge.
What drives AC repair cost beyond the part
The failed part sets the baseline, but a few other factors move the final number.
Labor rates and service call fees
| Fee type | Typical cost |
|---|---|
| Diagnostic or service call fee | $75 to $150 |
| Standard labor rate | $75 to $200 per hour |
| High-cost market labor rate | Up to $200+ per hour |
Labor rates vary by region and by how specialized the technician is. A repair that takes two hours in a rural area might run $150 to $300 in labor, while the same job in a major metro area could run $300 to $600.
Most companies apply the diagnostic fee toward the repair cost if you approve the work, so it’s worth asking that question before the technician even opens the panel.
Emergency and after-hours pricing
Timing changes the price more than most homeowners expect. A capacitor that fails during a routine spring tune-up might be a $150 fix.
The same capacitor discovered on a 100-degree Saturday in July, when every HVAC company in town is booked, can become a $600 bill once emergency rates apply.
After-hours and weekend service calls can run up to $250 per hour in some markets, roughly double the standard daytime rate.
If your AC failure isn’t a true emergency (the house is uncomfortable but not dangerously hot, or you have somewhere else to stay for a day), waiting for standard business hours can meaningfully lower the bill.
AC unit type and repair cost
| System type | Typical repair cost | Notes |
|---|---|---|
| Central air conditioning | $200 to $2,500 | Widest range since it covers both minor fixes and major component failures |
| Window or portable unit | $75 to $300 | Simpler systems with fewer components to fail |
| Ductless mini-split | $150 to $1,500 | Costs depend on whether the issue is in the indoor head or the outdoor compressor unit |
Central systems carry the widest cost range because they have the most components and the most labor-intensive access, especially when the condenser sits on a roof or in a tight crawlspace.
Window and portable units are cheaper to repair across the board, largely because the electrical and refrigerant systems are smaller and more accessible.
Mini-splits fall in between: routine issues with a single indoor head are usually inexpensive, but a failure in the shared outdoor compressor affects every connected zone and costs closer to central system pricing.
Repair or replace? How to decide
- Get a written, itemized repair quote before deciding anything.
- Find out what a new system would cost for your home size and system type; central AC replacement typically runs $3,000 to $7,500 in 2026.
- Apply the 50% rule: if the repair quote is 50% or more of the replacement cost, replacement is usually the better long-term value.
- Check refrigerant type. If your system uses R-22, treat any major repair as a stronger signal to replace, even if the repair quote alone doesn’t hit the 50% threshold.
The 50% rule, explained
The 50% rule is a simple filter: divide your repair quote by the cost of a full replacement, and if that ratio is 0.5 or higher, replacement is usually the smarter financial move.
A $1,200 repair on a system that would cost $4,000 to replace stays comfortably under that line, and repair makes sense.
A $2,200 repair on the same $4,000 replacement pushes past the threshold, and a new system starts to look like the better bet, especially since it also comes with a warranty and improved efficiency.
When an old refrigerant type repairs a bad bet
For older systems, refrigerant type can override the standard 50% math. A major repair such as a failed compressor or evaporator coil on an R-22 system commonly costs $1,500 to $2,000, not counting refrigerant.
Add a refrigerant recharge at current R-22 pricing, and that same repair can reach $2,500 to $3,000 before the job is done.
Compare that to a new system in the $5,000 to $10,000 range (or higher for heat pumps), and the repair no longer clears 50% of replacement cost by much of a margin, if at all, once refrigerant is factored in. R-22 systems are also typically at least 15 years old and run at 8 to 12 SEER efficiency, well below the 16 SEER2 or higher ratings available on new equipment.

Does insurance or warranty cover AC repair?
Standard homeowners insurance and manufacturer warranties cover AC repair in very different circumstances, and mixing the two up is a common source of surprise bills.
Manufacturer and home warranty coverage
A manufacturer’s warranty typically covers parts for 5 to 10 years from installation, but usually only labor for the first 1 to 2 years unless you purchased an extended labor warranty separately.
If your system is still under the manufacturer’s parts warranty, you may only pay for labor on a covered repair rather than for the part itself.
A separate home warranty plan, the kind purchased annually and covering multiple home systems, generally covers AC repairs caused by normal wear and mechanical failure, but excludes damage from lack of maintenance, pre-existing issues, or improper prior installation.
When homeowners insurance applies
Standard homeowners insurance does not cover routine AC breakdowns or wear-related failures. It typically covers damage from a sudden, specific event, such as a lightning strike, fire, or falling tree limb that damages the unit.
If your AC stopped working because a part wore out or refrigerant leaked over time, that’s considered maintenance-related and falls outside typical homeowners coverage.
It’s worth checking your specific policy, since coverage details vary by insurer, but don’t expect a routine compressor failure to be a covered claim.
How to avoid overpaying for AC repair
- Get a written, itemized estimate before any work begins, and confirm the diagnostic fee will be credited toward the repair if you approve it.
- Ask what refrigerant your system uses before agreeing to any recharge, since that single detail can double or triple the cost of an otherwise routine repair.
- Get a second opinion on any quote above $1,000, particularly for compressor or coil work, since these are the repairs with the widest pricing variation between contractors.
- Schedule non-emergency repairs during spring or fall when demand is lower, rather than during a summer heat wave when emergency rates apply.
- Ask about a maintenance plan if you don’t already have one; regular tune-ups catch small issues, like a weakening capacitor, before they turn into full system failures. See our guide to annual HVAC maintenance plan cost for current pricing.
Before you call anyone, it helps to know who you’re calling.
Our guide on how to vet a licensed HVAC technician covers what licensing and insurance to ask for, and how to spot a quote that’s padded beyond the ranges covered above.
Request a written estimate before any work starts, and you’ll be in a much stronger position to know whether a quote is fair.
Frequently asked questions
How much does it cost to fix an AC unit?
Most AC repairs cost between $150 and $650, with a national average around $375.
The exact price depends on which part failed: minor issues like a capacitor or clogged drain line run $100 to $300, while major repairs involving the compressor or evaporator coil can reach $1,000 to $2,800 or more.
Emergency or after-hours service typically adds to whatever the base repair would otherwise cost, sometimes doubling the standard rate.
What is the 50% rule for AC replacement?
The 50% rule says that if a repair quote comes to 50% or more of what a full system replacement would cost, replacement is usually the better financial choice.
For example, a $2,000 repair quote on a system that would cost $3,500 to replace crosses that threshold, since $2,000 is more than half of $3,500.
The rule accounts for the fact that an aging system likely to need this repair is also likely to need another one soon, while a new system comes with a fresh warranty and better efficiency.
Does homeowners insurance cover AC repair?
Standard homeowners insurance does not cover routine AC repairs caused by wear, age, or mechanical failure. It only applies when damage results from a specific covered event, such as fire, lightning, or a fallen tree limb.
A refrigerant leak, a worn-out capacitor, or a failed compressor from normal use is treated as a maintenance issue, not an insurance claim, so most homeowners pay for these repairs out of pocket or through a separate home warranty plan if they have one.
How much does it cost to recharge refrigerant in 2026?
A refrigerant recharge costs $200 to $1,500 depending on refrigerant type and how much the system needs.
R-410A recharges run $500 to $1,500 for a typical 6 to 12 pound system, at current 2026 pricing of $80 to $150 per pound installed.
Older R-22 systems cost significantly more: at $150 to $300 per pound, a full recharge including labor can reach $750 to $4,500.
Because a properly sealed AC system should not need refrigerant added regularly, a recharge request almost always means there’s a leak that needs to be found and repaired first, not just topped off.
