💼 Why AC System Costs Can Vary So Widely

Before we dive into price ranges, it’s important to understand why quotes vary so much between homes.

Factors That Influence Pricing:

• Climate zone and cooling demand

• Electrical panel capacity

• Duct condition or rerouting

• Permitting and code compliance

• Type of home (crawlspace, attic, slab)

⚠️ Pro Tip: Never base your budget on the equipment price alone — labor and installation extras often double the cost.
