1. What is the AC Unit Cost Calculator?

This calculator estimates the cost of an air conditioning unit based on your home's square footage and the cost per ton of cooling capacity. It helps homeowners budget for new AC installations.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• 400 sq ft — Standard area that 1 ton of cooling capacity can effectively cool
• Cost per Ton — Current market price for AC units per ton of capacity

Explanation: The formula first calculates how many tons of cooling capacity your home needs, then multiplies by the cost per ton to get the total estimated cost.

3. Importance of Proper AC Sizing

Details: Properly sizing your AC unit is crucial for energy efficiency and home comfort. An oversized unit will cycle on and off too frequently, while an undersized unit will struggle to cool your home.

4. Using the Calculator

Tips: Measure your home's total square footage accurately. For the cost per ton, check current prices at Home Depot or other retailers (typically $1,500-$3,500 per ton including installation).

5. Frequently Asked Questions (FAQ)

Q1: Is 400 sq ft per ton always accurate?
A: This is a general rule. Factors like ceiling height, insulation, climate, and sun exposure may require adjustments.

Q2: What's included in the cost per ton?
A: Typically includes the AC unit itself, installation labor, and basic materials. Additional costs may apply for ductwork or electrical upgrades.

Q3: Should I get multiple estimates?
A: Yes, always get at least 3 estimates from licensed HVAC contractors for comparison.

Q4: What about SEER ratings?
A: Higher SEER units cost more but save on energy bills. This calculator provides a base estimate that should be adjusted for efficiency choices.

Q5: Does this include central air systems only?
A: Yes, this estimates central AC costs. Ductless mini-split systems have different pricing structures.
