Home Ac — Good

| Type | Best For | Pros | Cons | |------|----------|------|------| | | Whole homes with ductwork | Even cooling, out of sight, adds home value | High install cost, requires ducts | | Ductless Mini-Split | Homes without ducts, room additions, older homes | Zoned cooling, very efficient, quiet | Higher upfront per zone, visible indoor units | | Window AC | Single rooms, renters, small budgets | Low cost, easy DIY install | Blocks window, noisy, inefficient | | Portable AC | Temporary cooling, odd-shaped rooms | Movable, no permanent install | Least efficient, takes floor space, noisy | | Heat Pump | Mild to moderate climates | Heats & cools, very efficient year-round | Higher upfront, less effective in extreme cold (without backup) | Recommendation: For most single-family homes, a central AC or ductless mini-split offers the best balance of comfort and efficiency. 3. Bigger Is NOT Better (Sizing Matters) This is the most common mistake homeowners make. An oversized AC will cool the air so fast that it doesn’t run long enough to remove humidity. The result? A cold, clammy, mold-prone house. An undersized unit runs constantly, drives up bills, and wears out quickly.
