How much does it cost to install central air with ductwork?

The cost to install central air with ductwork is confirmed after an in‑home evaluation because price depends on your home and the scope of ductwork. Parobek Plumbing & Air Conditioning offers an A/C install from $135/month with a free proposal (limited-time offer; cannot be combined with other promotions). In many homes, the amount of new ductwork and sealing needed drives more of the total than the outdoor unit itself. Most central AC installations take 1 to 5 days, depending on layout and any duct repairs. Our team installs systems in the Elgin area regularly and follows manufacturer specs and safety standards.

Key factors that set your price:

• New duct design vs. repairing existing ducts and number of supply/return runs
• Home size, insulation levels, and layout complexity
• Equipment efficiency and brand selection
• Electrical, drain, and refrigerant line modifications
• Add‑ons like smart thermostats, filtration, or dehumidifiers

Schedule a free proposal so a technician can size the system, inspect the ducts, and provide a firm written quote before you decide.
