*Warranty applies to registered units and may not cover labor.
How The Air Conditioner Compressor Works
The compressor is central to an air conditioning system. It compresses refrigerant gas, raising its pressure and temperature, before sending it to the condenser coil. This cycle enables heat exchange and cools your home.
When this component breaks, your AC cannot properly cool—the rest of the system may turn on, but you’ll feel little to no cold air. Compressor failure is often a sign of age or underlying system issues.
Typical Costs For New Air Conditioner Compressors
The cost for a new AC compressor depends heavily on system type, brand, refrigerant used, size (tonnage), and whether you’re buying only the part or paying for full installation.
Central Air Conditioner Compressors
For a standard residential split or packaged central AC, the compressor part costs $400 to $1,800, depending on capacity (1.5–5 tons), brand, and efficiency ratings.
Installed, total average costs range from $1,100 to $3,500. High-efficiency and two-stage or variable-speed compressors fetch higher prices and labor charges.
Window and Portable AC Compressors
Compressor parts for window or portable AC units typically cost $160–$500. However, labor may be prohibitively expensive compared to buying a new unit. Full replacement (parts and labor) averages $350–$850.
Mini-Split (Ductless) Compressors
Ductless mini-split outdoor unit compressors generally run $500–$1,400 for the part. With labor, total installed costs average $900 to $2,800 depending on BTU rating and brand.
Commercial Compressors
Compressors for commercial HVAC systems (over 5 tons) can cost $1,800–$7,500 or more for the part alone, with labor often exceeding $2,000–$5,000.
Key Factors That Influence Compressor Replacement Cost
- Size and Tonnage: Larger homes and AC systems require stronger compressors, increasing cost. Typical U.S. homes use 1.5 to 5-ton units.
- Efficiency and Speed: Two-stage or variable-speed compressors are more expensive than single-stage counterparts but may offer better efficiency.
- Refrigerant Type: Newer systems using R410A (vs. R22, which is phased out) may dictate replacement choices and price.
- Brand Specificity: Carrier, Trane, Lennox, Goodman, Bryant, and American Standard vary in compressor part pricing and dealer markups.
- Warranty Status: Replacing a failed compressor under warranty usually means you only pay labor ($600–$1,400), not the part.
- Labor Charges: Labor for compressor replacement often ranges $700–$2,400, depending on unit accessibility and contractor rates.
- Location: Major metro areas tend to have higher HVAC costs than rural regions.
Comparing Compressor Replacement To System Replacement
| Scenario | Recommended Action | Key Considerations |
|---|---|---|
| System < 8 Years & Under Warranty | Replace Compressor | Less expensive, warranty covers parts, restores function. |
| System 8–12 Years, No Warranty | Evaluate Replacement | Compressor cost can be half the price of a new unit; factor energy savings of newer models. |
| System 12+ Years, Multiple Repairs | Replace Entire System | Old systems are less efficient and prone to more breakdowns; replacing the whole system may be more cost-effective long-term. |
Major Brands & Compressor Pricing Overview
Popular residential AC compressor brands include Carrier, Trane, Goodman, Lennox, American Standard, Bryant, York, and Rheem. Each brand’s compressors are proprietary and must match your system’s model/tonnage.
- Carrier/Trane/Lennox: Premium brands; replacement compressors range $750–$1,800 (part only).
- Goodman/Rheem: Budget to mid-range; $400–$1,000 (part only).
- York/American Standard/Bryant: Mid-priced; $600–$1,400 (part only).
Authorized dealers and certified technicians must perform the replacement to preserve warranty and ensure proper installation.
Warranty Coverage For Air Conditioner Compressors
Most major brands offer 5–10 year limited warranties for compressor parts if you register your product. Labor is usually not included, and coverage can be voided if annual maintenance is neglected.
- Check your warranty status—serial number and model location is usually on the outdoor unit.
- If under warranty, you typically pay for labor only. Labor can still run $700–$1,400 depending on complexity.
- Unregistered or lapsed warranties mean paying full price for parts and labor.
Labor Breakdown For Compressor Replacement
Replacing an AC compressor takes 3–8 hours, depending on system type and site access. HVAC service calls (diagnostics and labor) are billed at $70–$150 per hour nationwide, but major metro areas may command higher rates.
Replacement includes:
- Recovering refrigerant (removal and proper disposal per EPA regulations)
- Disconnecting and removing the failed compressor
- Installing and wiring the new compressor
- Vacuuming and refilling refrigerant charge
- Testing operation and pressure levels
Complex installations with difficult access, changes to piping, or refrigerant conversions (from R22 to R410A) add more labor time and cost.
Signs Your Air Conditioner Compressor May Need Replacement
- AC blows warm or room-temperature air even when set to cool
- Loud clanking, grinding, or hissing noises from the outdoor unit
- Outdoor fan runs but compressor does not turn on
- Repeated tripping of circuit breakers when AC tries to start
- Visible refrigerant leaks near the compressor shell
- High energy bills and frequent short cycling
Early diagnosis and repair may extend system life and prevent catastrophic damage to other components.
Should You Repair Or Replace A Compressor?
Make your decision based on system age, warranty coverage, repair frequency, and overall AC condition. Compressor replacement makes sense for newer, warrantied units. Older units (10–15 years), especially those using phased-out R22 refrigerant, are often better replaced entirely.
Key questions to ask your HVAC contractor:
- Is the compressor failure isolated or symptomatic of system-wide issues?
- Will replacing the compressor resolve the cooling issue, or is your entire system at risk of further breakdowns?
- Will upgrading to a new unit save you on energy bills and costly repairs?
How To Choose The Right Compressor Replacement
- Always match the compressor to the system’s model and refrigerant type.
- Work with licensed, experienced HVAC technicians authorized for your AC brand.
- Request multiple quotes from reputable contractors for transparency on labor, parts, and warranty implications.
Money-Saving Tips For Compressor Replacement
- Check your warranty before agreeing to major repairs—it can save you thousands.
- Consider seasonal promotions and rebates for new system installs if a replacement is likely.
- Maintain your system annually to prevent compressor strain and maximize warranty coverage.
- Don’t delay repairs—a struggling compressor can damage coils and other expensive components.
Frequently Asked Questions About AC Compressor Cost
- Can I replace my own AC compressor? No, EPA regulations require licensed technicians for refrigerant handling and compressor installation.
- Is it cheaper to rebuild or replace a compressor? In most residential scenarios, replacement is more reliable and cost-effective than a rebuild.
- Does homeowner’s insurance cover compressor failure? Typically not, unless failure was caused by a covered event like lightning or vandalism.
- How long do air conditioner compressors last? With annual maintenance, most last 10–15 years.
- Where can I buy replacement compressors? HVAC supply houses, authorized dealers, and contractors source brand-specific compressors. Online retailers exist but may not honor or process warranties.
