Step-by-Step Examples
Example 1
2,000 sq ft Standard Replace
2,000 sq ft, standard AC replacement.
- ~4 tons needed | Standard efficiency
- Estimate: $6,000 – $10,000
✓ $6,000 – $10,000
Example 2
High Efficiency 2,500 sq ft
2,500 sq ft, high efficiency heat pump.
- ~5 tons | High efficiency
- Estimate: $12,500 – $20,000
✓ $12,500 – $20,000
Example 3
New Install with Ductwork
1,500 sq ft, new system + ductwork.
- ~3 tons + $5K ductwork
- Estimate: $9,500 – $17,500
✓ $9,500 – $17,500

Common Mistakes to Avoid
⚠️
Using only 1 quote
HVAC contractor prices vary 30-50% for the same system. Always get at least 3 quotes from licensed contractors.
⚠️
Buying oversized systems
Bigger isn't better for HVAC. An oversized system short-cycles, creates humidity problems, and wears out faster. Proper load calculation (Manual J) determines correct size.
Frequently Asked Questions
How is HVAC size determined? ▾
Manual J load calculation: based on square footage, insulation levels, window area, climate zone, and ceiling height. 1 ton cools approximately 400-600 sq ft.
How long does HVAC last? ▾
Central AC: 15-20 years. Heat pump: 15 years. Furnace: 20-25 years. With regular maintenance, systems can last longer.
When to repair vs replace? ▾
Rule of thumb: if repair cost exceeds 50% of replacement cost and unit is over 10 years old, replace. Modern units are significantly more efficient than older ones.
