1. What is a 3 Ton Heat Pump?

A 3 ton heat pump is a common residential HVAC system size. The "ton" refers to cooling capacity, where 1 ton = 12,000 BTU/hour. A 3 ton unit provides 36,000 BTU/hour of cooling capacity.

2. How Does the Calculator Work?

The calculator uses the standard rule of thumb:

Where:

• 1 ton covers approximately 500 square feet
• 3 tons covers approximately 1,500 square feet
• This is a general estimate that varies by climate and home characteristics

3. Importance of Proper Sizing

Details: Proper heat pump sizing is crucial for efficiency and comfort. Oversized units short cycle, reducing efficiency and lifespan. Undersized units can't maintain temperature during extreme weather.

4. Using the Calculator

Tips: Enter the heat pump tonnage (typically 1-5 for residential systems). The calculator will estimate the appropriate square footage coverage. Note this is a general estimate - consult an HVAC professional for exact sizing.

5. Frequently Asked Questions (FAQ)

Q1: Is 500 sq ft per ton always accurate?
A: No, this varies by climate (400-600 sq ft/ton in hot climates, 500-800 in moderate, 600-1,000 in cold climates).

Q2: What factors affect heat pump sizing?
A: Insulation quality, ceiling height, window area, local climate, and home orientation all affect sizing needs.

Q3: Can I use this for commercial buildings?
A: No, commercial buildings have different load calculations and typically need professional Manual J calculations.

Q4: What if my home is well insulated?
A: Well-insulated homes may need less tonnage (perhaps 600-800 sq ft per ton).

Q5: Should I size for cooling or heating?
A: In most climates, size for cooling needs as heating capacity is typically adequate if cooling is properly sized.
