x402
HVAC Efficiency Unit Converter is a paid API for AI agents from hvac-calc.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-30).
Converts between HVAC efficiency ratings (EER, COP, kW/ton) and cooling capacity units (tons, BTU/h, kW).

How this service works
Convert EER, COP and kW per ton, and tons, BTU/h and kW of cooling capacity.
Output
Returns all three efficiency metrics (EER, COP, kW/ton) and all three capacity units (tons, BTU/h, kW thermal) derived from the inputs provided, along with electrical kW, a human-readable summary, a verdict, and a disclaimer. Null values appear for fields that cannot be derived without additional input.
Example use cases
Comparing AC efficiency across rating systems
“I'm comparing two air conditioners — one is rated at 14 EER and the other at COP 4.1. Can you convert both to the same units so I can see which is more efficient?”
Cooling capacity unit conversion for equipment spec
“Our chiller is rated at 150 kW of cooling. Can you convert that to tons of refrigeration and BTU/h for the equipment schedule?”
Energy audit efficiency metric normalization
“I have a unit rated at 0.65 kW per ton — what is that in EER and COP so I can compare it to international efficiency standards?”
Technical details
Endpoint
GEThttps://hvac-calc.x402tookit.com/efficiency-convert?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to interconvert HVAC efficiency ratings (EER, COP, kW/ton) or cooling capacity units (tons, BTU/h, kW) in a single call. Ideal for engineering tools, energy audits, equipment comparisons, and building system specifications where multiple unit systems are in use. Prefer this over manual formulas when you need a validated, structured response with a summary and disclaimer.
Side effects
- Missing required input: neither an efficiency metric nor a capacity value provided — returns error or nulls
- Ambiguous input: sending more than one efficiency metric (e.g. both EER and COP) may cause conflict
- Invalid numeric values (negative or zero) may produce nonsensical results
- Capacity-only input without efficiency metric yields capacity conversions but null efficiency fields
- Network or payment failure returns HTTP 402 or 5xx with no conversion data
