3 Ton DiamondAir 14.3 SEER2 R32 Central System D1436ACL32A, D1436HAEAL32A
This DiamondAir system pairs the D1436ACL32A condenser with the D1436HAEAL32A multipoise air handler, AHRI certified at 14.3 SEER2 (#218350142). It runs on R-32, a low-GWP A2L refrigerant, and the air handler includes a factory-installed R-32 leak sensor that shuts down the compressor and electric heat if a leak is detected. It's cooling only, with electric heat kits from 5 kW up to 15 kW available.
Is a 3 Ton Air Conditioning System the Right Size?
A 3 ton system is often used in 3-bedroom homes around 1,500–1,800 sq. ft. as a general guide. Hot, humid climates may need more capacity.
Return air and duct sizing matter as much as the equipment at this size. Pair a Manual J load calculation with a duct check.
Ideal for: 3-bedroom single-family homes and larger townhomes.
Need more capacity? Step up to the 3.5 Ton DiamondAir 14.3 SEER2 R32 Central System D1442ACL32A, D1442HAEAL32A for a larger load.
Recommended home sizes are general guidelines only. Actual system requirements depend on insulation, climate, windows, ductwork, occupancy and a proper load calculation. Request free sizing assistance, contact Budget Heating, or call 813-885-7999.

Frequently Asked Questions
How is a 15 kW heat kit wired in the D1436HAEAL32A?
The 15 kW kit uses two circuits. DiamondAir lists circuit 1 at 37.9 MCA / 40A and circuit 2 at 24.9 MCA / 25A at 230V.
How big is the 3 ton D1436ACL32A condenser?
DiamondAir lists it at 25" tall on a wider 29-1/8" x 29-1/8" base, with a 160 lb shipping weight.
Is there a minimum room size for this R-32 system?
Yes. Because R-32 is an A2L refrigerant, the installation manual sets a required minimum conditioned area based on the total system refrigerant charge. Your installer calculates it from the manual's tables.
How does this R-32 system compare to the R-410A DiamondAir 3 ton system?
The 3 ton DiamondAir R-410A system D1436ACL2, D1436HAEAL2 is the earlier version. This R-32 match uses a refrigerant with a much lower global warming potential and adds a factory-installed leak sensor in the air handler.
Is there a 3 ton DiamondAir R-32 heat pump system?
Yes. The 3 ton DiamondAir R-32 heat pump system D1436HCL32A, D1436HAEAL32A uses the same air handler and adds heating from the outdoor unit.
What outdoor temperatures can the D1436ACL32A cool in?
DiamondAir lists a cooling operating range of 55°F to 120°F outdoor ambient.
