The Lennox SL28XCV series price reflects high-efficiency, variable-capacity HVAC equipment and the total cost typically ranges from a few thousand for the unit to over ten thousand with full installation. Buyers usually pay based on unit capacity, ductwork condition, labor rates, and local permit needs; this article focuses on realistic U.S. pricing and the main cost drivers for the SL28XCV.

What Buyers Typically Pay for a Lennox SL28XCV Furnace or Packaged Unit
Typical total price for a Lennox SL28XCV installed in a 1,800–2,500 sq ft U.S. home falls between $5,000 and $12,500 depending on scope. Average installed price is about $8,500 for a straightforward like-for-like replacement with standard venting and no major duct changes.
Assumptions: Midwest labor rates, 80k BTU nominal capacity, standard gas line, basic thermostat.
How Typical Installation Quotes Break Down: Materials, Labor, Equipment, Permits
| Materials | Labor | Equipment | Permits | Delivery/Disposal |
|---|---|---|---|---|
| $2,200-$6,000 (unit, venting, accessories) | $1,200-$3,500 () | $150-$900 (lift, rigging) | $50-$400 | $75-$400 (old-unit haul) |
Material cost is the largest single line item for SL28XCV installs, but labor and ductwork can double the total on complicated jobs.
Major Variables That Can Raise or Lower an SL28XCV Quote
Two strong variables that affect price are installed capacity and duct condition: upgrading from a 60k–80k BTU to a 95k–120k BTU model typically adds $800-$2,500 to equipment and installation; replacing or sealing 200+ linear feet of ductwork can add $2,000-$6,000. Other big drivers include conversion to power venting, furnace AFUE rating, and whether a two-stage or modulating control is added.
Numeric thresholds: capacity tiers 60k–80k, 95k–120k; duct runs: under 100 ft, 100–200 ft, over 200 ft.

Practical Ways To Lower SL28XCV Project Price Without Sacrificing Safety
Buyers can reduce cost by scheduling work in shoulder seasons, choosing standard controls instead of premium smart HVAC suites, and preparing the site (clear access, pre-emptive removal of old equipment). Getting three itemized quotes and specifying identical scopes (same capacity, same accessories) typically saves 5–15% compared with accepting the first quote.
Other options include reusing existing thermostats or air cleaners if compatible, and grouping upgrades with other home projects to negotiate labor rates.
How Prices Vary Across U.S. Regions for SL28XCV Installations
Regional labor and permit differences change the installed price: expect about 10–20% higher costs in Northeast/West Coast metro areas and about 5–15% lower in parts of the Midwest and South. A $8,500 average in the Midwest could be $9,400-$10,200 in an expensive metro area and $6,800-$8,000 in lower-cost regions.
Assumptions: similar unit and comparable scope; does not account for extreme rural travel surcharges.
Three Real-World Quote Examples With Specs and Pricing
| Scenario | Spec | Labor Hours | Price |
|---|---|---|---|
| Basic Replacement | 80k BTU SL28XCV, reuse ducts, standard vent | 6–10 hours | $5,000-$7,000 |
| Ductwork Repair | 80k BTU, 120 ft ducts sealed, 2 new boots | 12–20 hours | $8,500-$12,000 |
| Full Upgrade | 95k BTU, new high-efficiency venting, air cleaner, smart thermostat | 18–30 hours | $12,000-$18,000 |
Example quotes show how labor hours and added accessories push totals from basic replacement to full upgrade territory.
Compare the SL28XCV Price With Lower-Cost and Premium Alternatives
Lower-cost basic furnaces from other brands may be $1,000-$3,000 cheaper for the unit but often have lower efficiency or fewer modulating features; premium Lennox or competitor premium lines with advanced controls can exceed SL28XCV prices by $1,500-$4,000. Deciding between a cheaper unit and the SL28XCV depends on expected energy savings, lifespan, and planned home occupancy time.
