How Much Does HVAC Installation Cost With Ductwork Included?

HVAC installation with ductwork included from Del-Air is quoted after an on-site evaluation because system size, duct design, and home access conditions set the price. Most costs hinge on matching the right capacity to your home and how much existing ducting must be repaired or replaced. Our teams routinely handle full system-and-duct installs around the Orlando area, where tight attics and older returns are common. A technician will take airflow and pressure readings so the equipment and ducts are right-sized together, and you’ll get clear repair-versus-replace guidance after inspection. Free estimates on new systems are available.

Key factors that move pricing up or down:

• New supply/return runs or added zones
• Duct material choice and insulation rating
• Attic or crawlspace accessibility and lift needs
• Smart thermostat, air quality add-ons, or required performance tests

For an accurate quote, request a Manual J load calculation and a duct leakage test during your visit.
