3.5 Ton DiamondAir 14.3 SEER2 R32 Central System D1442ACL32A, D1442HAEAL32A
This DiamondAir system pairs the D1442ACL32A condenser with the D1442HAEAL32A multipoise air handler, AHRI certified at 14.3 SEER2 (#218350143). 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 20 kW available.
Is a 3.5 Ton Air Conditioning System the Right Size?
A 3.5 ton system is common in larger 3- and 4-bedroom homes around 1,800–2,100 sq. ft. as a rough guide.
This size needs more return air than a 3 ton, and undersized ducts cost efficiency. A Manual J load calculation and a duct review confirm the fit.
Ideal for: Larger 3- and 4-bedroom homes and open-concept layouts.
Need more capacity? Step up to the 4 Ton DiamondAir 14.3 SEER2 R32 Central System D1448ACL32A, D1448HAEAL32A 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.
