1.5 Ton DiamondAir 14.3 SEER2 R32 Central System D1418ACL32A, D1418HAEAL32A
This DiamondAir system pairs the D1418ACL32A condenser with the D1418HAEAL32A multipoise air handler, AHRI certified at 14.3 SEER2 (#218350139). 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 optional 5 or 8 kW electric heat kits.
Is a 1.5 Ton Air Conditioning System the Right Size?
A 1.5 ton system delivers 18,000 BTU/h of nominal cooling. It typically fits condos, apartments, small single-story homes and additions, roughly 600–900 sq. ft. as a loose guide.
Sun-facing windows, attic insulation and leaky ducts all change the real load. A Manual J load calculation is the reliable way to confirm 1.5 tons.
Ideal for: Condos, apartments, small single-story homes and additions on a budget.
Need more capacity? Step up to the 2 Ton DiamondAir 14.3 SEER2 R32 Central System D1424ACL32A, D1424HAEAL32A, which uses the same size air handler cabinet.
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
What happens if the D1418HAEAL32A detects an R-32 leak?
The factory-installed sensor stops the compressor and shuts off the electric heater, while the blower keeps running to dilute the refrigerant. The system resumes about 5 minutes after refrigerant is no longer detected.
Does the D1418HAEAL32A come with an air filter?
No. DiamondAir states the filter is not factory installed, so an external return-air filter or filter grille is required. Don't double-filter the return or filter the supply.
How does this R-32 system compare to the R-410A DiamondAir 1.5 ton system?
The 1.5 ton DiamondAir R-410A system D1418ACG2, D1418HAEAL2 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 1.5 ton DiamondAir R-32 heat pump system?
Yes. The 1.5 ton DiamondAir R-32 heat pump system D1418HCL32A, D1418HAEAL32A uses the same air handler and adds heating from the outdoor unit.
What is the largest heat kit for the 1.5 ton D1418HAEAL32A?
DiamondAir lists 5 kW and 8 kW kits for the 1.5 ton cabinet. At 230V, the 5 kW kit is rated 24.9 MCA / 25A and the 8 kW kit 37.9 MCA / 40A.
How big is the D1418ACL32A condenser?
DiamondAir lists it at 25" tall on a 23-5/8" x 23-5/8" base, with a 139 lb shipping weight.
