How much does it cost to install a new AC and furnace?

The cost to install a new AC and furnace with Clark Heating and Cooling is confirmed after an in‑home evaluation because equipment size, efficiency, and installation conditions drive the price. Most variation comes from matching the right tonnage and BTU outputs, needed duct changes to fix airflow, and access limits in attics or tight spaces. A correctly sized system with balanced ducts often outperforms a larger unit that struggles against high static pressure. If both units are near end of life, a combined changeout can reduce labor overlap; if one still has life, a repair or staged plan may be smarter. Our crews install systems across the Phoenix area and build for desert heat.

Your itemized quote may include:

• Correct equipment size (AC tonnage and furnace BTU)
• Efficiency level selected (SEER2 and furnace AFUE)
• Duct modifications to balance airflow or resize runs
• Scope extras: line-set or drain replacement, electrical or gas/vent fixes, thermostat/IAQ upgrades; Maintenance Plan member discounts (5% off single-unit)
