AC Sizing for Port St. Lucie Homes
The biggest mistake in Port St. Lucie AC installation is wrong sizing. An oversized AC cools fast but can't remove humidity — leaving your home clammy despite low temperatures. An undersized unit runs constantly and never catches up.
| Home Size (sqft) | AC Size (tons) | BTU Capacity |
|---|---|---|
| 1,000–1,200 | 1.5–2.0 | 18,000–24,000 |
| 1,200–1,500 | 2.0–2.5 | 24,000–30,000 |
| 1,500–2,000 | 2.5–3.0 | 30,000–36,000 |
| 2,000–2,500 | 3.0–3.5 | 36,000–42,000 |
| 2,500–3,000 | 3.5–4.0 | 42,000–48,000 |
| 3,000–3,500 | 4.0–5.0 | 48,000–60,000 |
Important: These are estimates. A proper Manual J load calculation is essential for Port St. Lucie homes because our extreme heat, humidity, window orientation, insulation levels, and ceiling heights all significantly affect cooling requirements. We perform Manual J calculations on every installation.
