National AC repair cost ranges (2025)
These national planning bands reflect parts plus labor for typical residential central air conditioning systems. Quotes vary by contractor rates, system accessibility, and parts availability.
Regional variation: Cost-of-living differences across U.S. markets mean that dense metro areas, coastal regions, and affluent suburbs typically fall in the upper portions of these ranges. Premium service providers with specialized expertise and higher operational standards may exceed national averages.
| Problem Type | Typical Cost Range | Typical Time | Primary Driver |
|---|---|---|---|
| Capacitor replacement | $120 to $475 | 1 hr | Part type and model access |
| Thermostat repair/replace | $135 to $440 | 1–2 hrs | Basic vs smart thermostat |
| Refrigerant recharge | $100 to $600 | 1–2 hrs | Refrigerant type (R-22 vs R-410A) |
| Drain line cleaning | $75 to $200 | 1 hr | Labor-focused service |
| Fan motor replacement | $250 to $700 | 2–3 hrs | Motor type and location |
| Circuit board replacement | $300 to $700 | 1–2 hrs | OEM vs universal board |
| Refrigerant leak repair | $225 to $1,600 | 2–8 hrs | Leak location and accessibility |
| Evaporator coil replacement | $1,000 to $2,000 | 4–8 hrs | Labor-intensive; refrigerant recovery |
| Compressor replacement | $1,200 to $2,800 | 4–6 hrs | Most expensive single repair |
Key takeaway: Most common single-component repairs range from $120 to $700; major components (coils, compressors) can exceed $1,000 due to parts costs and labor intensity.
Cost by component (parts vs installed)
Parts-only pricing compared to typical installed totals, assuming standard diagnostics and refrigerant handling where applicable.
| Component | Equipment Cost | Installation Cost | Total Installed Cost |
|---|---|---|---|
| Fuse or relay | $15–$50 | $75–$250 | $90–$300 |
| Drain line cleaning | Service only | $75–$200 | $75–$200 |
| Capacitor | $50–$200 | $70–$275 | $120–$475 |
| Thermostat | $60–$300 | $75–$140 | $135–$440 |
| Refrigerant recharge (R-410A) | $50–$150 | $50–$200 | $100–$350 |
| Refrigerant recharge (R-22) | $200–$400 | $50–$200 | $250–$600 |
| Expansion valve | $50–$300 | $50–$200 | $100–$500 |
| Fan motor | $150–$500 | $100–$200 | $250–$700 |
| Circuit board | $200–$500 | $100–$200 | $300–$700 |
| Refrigerant leak repair | Parts vary | $225–$1,600 | $225–$1,600 |
| Evaporator coil | $600–$1,500 | $400–$500 | $1,000–$2,000 |
| Condenser unit | $900–$2,500 | $500–$1,500 | $1,400–$4,000 |
| Compressor | $800–$2,000 | $400–$800 | $1,200–$2,800 |
Cost factors that affect the total price
-
System type:
Central AC systems cost more to repair than window units or ductless mini-splits due to size, complexity, and accessibility. Window unit repairs typically run $50–$125; ductless mini-splits $300–$900; central AC $171–$660 for common issues. -
Refrigerant type:
R-22 (Freon) refrigerant costs have increased significantly due to EPA phase-out regulations. R-410A refrigerant remains stable and widely available. Systems using R-22 should be evaluated for replacement rather than extensive recharge. -
System age and parts availability:
AC systems 10+ years old may require harder-to-find parts with longer lead times and higher costs. Discontinued components for older models increase total repair expenses. -
Accessibility and installation complexity:
Rooftop units, attic installations, and cramped mechanical rooms add 1–2 hours of labor time, increasing costs by $75–$300. -
Timing and urgency:
After-hours, weekend, and holiday service calls typically add $85–$100 per hour or apply multipliers of 1.5× to 2.0× standard rates.
Repair vs replacement decision thresholds
| Decision Factor | Repair Favored | Replacement Favored |
|---|---|---|
| System age | < 8 years | ≥ 12 years |
| Single repair cost | < $500 | > $1,000 |
| Repair history | First major issue | Multiple failures within 2 years |
| Efficiency (SEER/SEER2) | ≥ 14 SEER | < 13 SEER |
| Refrigerant type | R-410A | R-22 (Freon) |
| Warranty status | Active | Expired |
Rule of thumb: If repair cost exceeds ~50% of replacement cost AND the system is 10+ years old or uses R-22 refrigerant, replacement typically provides better long-term value. New SEER2 efficiency standards (minimum 13.4 in northern regions, 14.3 in southern regions as of 2023) make high-efficiency replacements more cost-effective over system lifetime.
Emergency service pricing (typical patterns)
| Service Window | Impact on Price | Illustrative Adder/Multiplier |
|---|---|---|
| Weekday business hours | Standard rate | Baseline |
| Evenings (5 PM–10 PM) | Higher diagnostic/first hour | ~1.5× or +$75–$150 |
| Late night (10 PM–6 AM) | Premium emergency rates | ~2.0× or +$150–$250 |
| Weekend days | Elevated rates | ~1.5× or +$75–$150 |
| Holidays | Maximum premium | ~2.0–2.5× or +$150–$250 |
Use emergency service for no-cooling during heat waves or safety hazards (electrical issues, refrigerant leaks); otherwise, schedule business-hours service to avoid premiums.
Methodology (concise)
- Labor economics: National HVAC wages from BLS (SOC 49-9021) inform billable contractor rates using standard multipliers (≈2.0–2.5× wage for overhead/burden/profit). Typical diagnostic and repair windows span 1 hour for simple component swaps to 8+ hours for leak detection and major component replacement.
- Parts pricing: Consumer-reported ranges used as secondary validation; OEM vs aftermarket parts, refrigerant type (R-22 vs R-410A), and model/brand availability widen cost bands.
- Scope alignment: DOE Energy Saver and EPA Section 608 regulations inform refrigerant handling requirements, efficiency standards, and competent diagnostic procedures (electrical testing, refrigerant pressure checks, airflow verification).
- Refrigerant context: EPA phase-out of R-22 refrigerant drives a significant cost differential between older and modern systems. R-410A systems offer stable, lower-cost refrigerant and align with current efficiency standards.
- Variability: Bands are national planning ranges; local market rates, accessibility challenges, urgent timing, system age, and refrigerant type drive variance.
Note on Regional Cost Variation
These national cost bands reflect pricing patterns across U.S. markets with varying economic conditions. Your local costs may differ based on:
- Geographic cost-of-living and prevailing wage rates
- Contractor licensing, certifications, and service standards
- Service urgency (routine vs. emergency timing)
- Equipment location and installation complexity
High cost-of-living regions and premium service providers typically align with the upper portions of these ranges or exceed them. Obtain local estimates for precise pricing in your market.
