R22 to R407c Conversion Cost and Typical Prices 2026
Converting an HVAC system from R22 to R407c typically costs between $400 and $2,500 depending on system size, leaks, and whether the compressor and oil are compatible. This R22 to R407c conversion cost summary shows low-average-high ranges and the main drivers contractors quote on jobsite visits.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Full conversion (residential split) | $400 | $1,000 | $2,500 | Assumptions: 2-3 ton, minor leaks, accessible unit. |
| Compressor replacement | $600 | $1,200 | $2,500 | Includes parts & labor for 2-3 ton unit. |
| Oil change/retrofit kit | $150 | $350 | $700 | Includes POE oil flush or partial oil change. |
| Evacuation & leak repair | $150 | $500 | $1,500 | Depends on leak access and length. |
Typical Total Price To Convert R22 To R407c For Residential Systems
Most homeowners pay $400-$2,500 to convert a residential R22 system to R407c, with $1,000 as a common mid-range estimate.
Low: $400 for a straight retrofit on a 1.5–2.5 ton AC with no oil change and no major leaks. Average: $1,000 for a 2–3 ton system including filter-drier, vacuum, oil treatment, and small leak repairs. High: $2,500+ when compressor replacement, extensive leak repair, or long refrigerant lines are required. Assumptions: Midwest labor rates, standard materials, normal access.
Breakdown Of Material, Labor, Equipment, Disposal, And Overhead
Material and labor make up the bulk of the quote; expect materials 40%-60% and labor 30%-50% of total price in many jobs.
| Materials | Labor | Equipment | Disposal | Overhead |
|---|---|---|---|---|
| $150-$700 (filter-drier, fittings, oil) | $150-$900 (2-8 hours at $75-$125/hr) | $50-$300 (vacuum pump rental or amortized) | $25-$150 (recovering and disposing old refrigerant) | $50-$400 (truck, diagnostics, admin) |
Contractors often quote an itemized invoice; request the parts list and labor hours to compare offers.
How System Size, Tons, And Leak History Change The Quote
Larger systems and chronic leaks increase cost quickly — conversions for 4+ ton systems often cost 2×–3× a small residential job.
Examples of numeric thresholds: replacing for a 1.5–3 ton residential unit: $400-$1,500. For 3.5–5 ton light commercial rooftop units: $1,200-$4,000. Multiple or inaccessible leaks (more than 2 repairs, run lengths over 50 linear feet) often add $300-$1,200 in labor and parts.
Practical Ways To Lower Conversion Price On An R22 System
Control scope: delay nonessential upgrades, do prep work, and get 3 written quotes to reduce the final bill.
Specific cost-saving tactics: bundle the conversion with scheduled maintenance to avoid separate service call fees, perform simple prep (clear access around units), accept compatible retrofit kits instead of full component replacement when manufacturer permits, and schedule work in shoulder seasons to avoid peak pricing.
Regional Price Differences: City, Suburban, And Rural Rates
Urban areas typically run 10%-30% higher than rural markets; coastal metros can be 20%-40% higher than Midwest averages.
Typical deltas: Midwest baseline. Northeast/West Coast: +15%-40%. Suburban areas: similar to baseline or +5%-15%. Rural: -10% to -20% if contractor travel is low. Assumptions: pricing reflects labor market, permit requirements, and travel time.
Extra Charges: Evacuation, Oil Change, Filter-Drier, And Vacuuming
Expect separate charges for deep vacuum, oil change/POE conversion, and a new liquid-line filter-drier — these add $150-$800 to many quotes.
| Task | Low | Average | High |
|---|---|---|---|
| Deep vacuum & leak test | $100 | $200 | $500 |
| Oil change / POE oil and flush | $100 | $300 | $600 |
| Filter-drier replacement | $50 | $150 | $350 |
| Refrigerant charge (if required) | $75 | $200 | $800 |
