Expect a $2,500-$7,500 premium for mid-to-high efficiency options versus base models.
Assumptions: upgrade to premium controls and higher SEER/IEER rated components.

Site Conditions That Drive Installation Labor and Rigging Costs
Labor and rigging costs vary by roof height, crane access, and curb condition; low-slope single-story roofs with curb access are cheapest. Numeric thresholds: rooftop under 20 ft adds $500-$2,000; heights 21-40 ft add $2,000-$6,000; heights over 40 ft often add $6,000-$12,000 for crane and safety rigging.
Assumptions: crane rental, certified rigging crew, typical OSHA requirements.
Ways to Reduce the Carrier 20 Ton Package Unit Price
Buyers can reduce cost by choosing standard-efficiency trims, scheduling in off-peak season, and preparing the site so contractors don’t face surprises. Typical savings: choose a base-efficiency unit and avoid custom duct modifications to save $3,000-$10,000.
- Bundle multiple units for volume pricing.
- Provide pre-installed curb or retain existing curb to avoid flashing work.
- Schedule install in spring/fall to avoid peak-season rush fees.
