The Lennox SL28XCV Series cost varies widely by system size, installation complexity, and region; most U.S. homeowners pay between $4,000 and $9,500 for a complete replace-install of a high-efficiency SL28XCV outdoor unit with matching indoor components. This article gives realistic low-average-high pricing, per-ton estimates, and the main variables that change a final quote for the SL28XCV line.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Complete Replace & Install (2–3 ton) | $4,000 | $6,000 | $9,500 | Assumptions: standard ductwork, suburban install, matching indoor coil |
| Outdoor Unit Only (2–3 ton) | $2,000 | $3,800 | $6,000 | Unit price varies by dealer and features |
| Per Ton Installed | $1,500 | $2,200 | $3,200 | Includes labor, basic materials, testing |
| Line-Set / Long Run Add-On | $200 | $500 | $1,200 | Depends on length and insulation |
Typical Total Price and Per-Ton Pricing for SL28XCV Replacements
Most homeowners buying a Lennox SL28XCV pay a bundled price that includes the condenser, matched coil, and full installation labor.
Typical total price for an average 2.5-ton home system: $4,500-$8,000 for mid-range installs; higher when adding ductwork or electrical upgrades. Unit-only prices commonly run $2,000-$5,500 by ton and model options. Per-ton installed ranges: $1,500-$3,200 per ton depending on materials and access. Assumptions: suburban installation, single-story home, standard SEER factory-matched indoor coil.
Breakdown of Quote Line Items for an SL28XCV Install
A realistic installer quote splits into materials, labor, equipment, permits, delivery/disposal, and warranty charges.
| Materials | Labor | Equipment | Permits | Delivery/Disposal | Warranty |
|---|---|---|---|---|---|
| $2,000-$6,000 (unit, coil, refrigerant) | $800-$3,000 () | $150-$700 (crane, lift, specialty tools) | $50-$400 (local) | $75-$350 (old unit disposal) | $0-$800 (extended warranties) |
Material costs drive the high end; labor reflects 6–14 hours typical for full swap. Assumptions: normal access, single-story roof/yard access.
How System Size, Duct Condition, and Line Length Change the Quote
System capacity, ductwork state, and refrigerant/line-set length are the strongest price levers on an SL28XCV quote.
Capacity: 2.0–2.5 ton systems typically sit near the low end; 3.0–5.0 ton systems add $800–$2,500 total. Ductwork: minor repairs $300-$1,200; full duct replacement $4,000-$12,000. Line-set length: under 25 ft often included; 25–50 ft add $200-$500; over 50 ft add $600-$1,500 plus potential efficiency loss fixes. Electrical: simple 30–60 amp breaker swap $200-$600; a 200A service upgrade adds $1,200-$3,500.
Practical Ways To Cut the SL28XCV Price Without Sacrificing Performance
Control scope, avoid unnecessary premium add-ons, and schedule installs in shoulder seasons to reduce the final price.
Options: keep the existing properly sized indoor coil if compatible ($500–$1,500 saved), bundle HVAC items (furnace+AC) for contractor discounts, accept standard factory warranty and buy extended coverage only if long-term plans justify cost. Prepare the site (clear access, level pad) to cut labor hours. Get 3 written quotes and require itemized pricing to compare like-for-like.
How Regional Market Differences Affect SL28XCV Pricing
Location changes price by roughly ±10–30%: higher in coastal/urban markets, lower in rural or lower-cost states.
Example deltas: Northeast/West Coast: +15–30% vs. national average; Midwest: -5–10%; South/Southwest: -5–15% depending on city. Labor rates influence totals: $75-$125 per hour in many metro markets; $50-$90 per hour in lower-cost areas. Assumptions: comparison between metro contractor pricing and regional averages.
Installation Time, Crew Size, and Labor Cost Expectations
Expect 6–14 hours of crew time for a straight swap; complex jobs take 1–3 days.
Typical crew: 2 technicians for most replace/installs; larger jobs add an assistant. Labor math example: with common inputs: 8 hours × $95/hr = $760. Diagnostic or start-up fees add $75-$200. Emergency or weekend installs can add 10–30% surcharge.
Common Add-Ons, Site Complications, and Their Typical Prices
Budget separately for duct upgrades, electrical service work, permit/inspection fees, and long refrigerant runs.
| Add-On | Low | Average | High |
|---|---|---|---|
| Minor Duct Sealing/Repair | $300 | $750 | $1,500 |
| Full Indoor Coil Replacement | $500 | $1,200 | $2,500 |
| Electrical Upgrade / Subpanel | $200 | $900 | $3,500 |
| Long Line-Set / Hard-to-Access | $200 | $600 | $1,500 |
