How To Size A 4 Ton AC Unit For Your Home
It’s critical to confirm that a 4 ton AC unit is the right size for your home. Oversizing or undersizing leads to poor comfort, high bills, and early equipment failure. Key considerations:
- Square Footage: Each ton cools about 500-700 square feet in average U.S. homes; 4 tons = 2,000-2,800 sq ft.
- Climate Zone: Hotter areas (e.g., Texas, Florida) may need more capacity for the same size house.
- Home Envelope: Insulation, windows, ceiling height and sun exposure can increase or decrease cooling needs.
- Occupant Load & Appliances: Large families, cooking, and electronics can raise required BTUs.
Contractors use Manual J load calculations to size the unit—never rely on guesswork or old rules of thumb.
Energy Efficiency Ratings And SEER2
Efficiency impacts both upfront and ongoing 4 ton AC unit costs. Beginning in 2023, U.S. federal rules require new central air conditioners to meet the SEER2 standard—an updated Seasonal Energy Efficiency Ratio.
- Southern U.S.: Minimum SEER2 is 14.3 (about SEER 15 under the old metric).
- Northern U.S.: Minimum SEER2 is 13.4 (about SEER 14 under the old rating).
Higher SEER2 units use less power, cutting summer cooling bills by 15–30% compared to the minimum. However, expect to pay $400–$1,400 more for a high-efficiency model.
| SEER2 Rating | 4 Ton Unit Price (Installed) | Estimated Annual Savings* |
|---|---|---|
| 14.3 | $4,800 – $6,200 | Baseline |
| 16 | $5,600 – $7,200 | $150 – $250 |
| 18+ | $6,800 – $9,500 | $250 – $400 |
*Savings vary based on usage patterns and local power rates.
Heat Pump Vs. Standard AC: Cost Differences For 4-Ton Units
A heat pump functions as both a central AC and a heater, moving heat in both directions. Upfront costs for a 4-ton heat pump typically run $500–$1,200 above a comparable AC, but they offer substantial energy savings in milder climates and often qualify for federal tax credits.
| System Type | Average Cost (Installed) | Best For |
