Commercial Air Handlers

The air handler is the part of a commercial system nobody photographs and everybody feels, because it is what actually moves conditioned air through the building. Specifying one is mostly a question of constraints rather than preference: what the electrical service supplies, how much room the mechanical space allows, and which orientation the duct connections already favour. Get those three right and the equipment disappears into the background, which is the whole point. Get one wrong and the unit either will not fit or will not run.

The alternative is putting everything on the roof in a single packaged cabinet, and our guide to rooftop HVAC units covers when that makes better sense. We stock the split side of that choice, Daikin air handlers alongside a Goodman unit, for contractors who need the indoor half specified properly, with voltage, phase and cabinet orientation stated on every listing rather than buried in a submittal.

Why Choose Commercial Air Handlers from HVAC Store?

• Voltage and phase are published on every unit, so the order matches the building service.

• Every multi position air handler here installs horizontal or vertical without a separate part number.

• Matched electric heat kits are available for three phase units, keeping the system on one supplier.

• Warranty cover against defects in materials and workmanship applies across the commercial range.

Best Commercial Air Handler Units for...

Light Commercial Retrofits

The best commercial air handler for a small retrofit runs on standard single phase service, which avoids an electrical upgrade. The Goodman 6 Ton Ducted Air Handler covers that at 230V.

Standard Three Phase Service

The best commercial air handling unit for a typical three phase building matches 208/230V service without a transformer. The Daikin 7.5 Ton Commercial Air Handler 208/230V suits mid sized zones.

Larger Conditioned Areas

The best air handler for a larger floorplate steps up to ten tons, since undersizing shows as long run times rather than a fault. The Daikin 10 Ton Commercial Air Handler 208/230V handles that load.

Buildings on 460 Volt Service

The best commercial air handler for a 460V building is one built for that service, because phase and voltage are not field convertible. The Daikin 10 Ton Commercial Air Handler 460V matches it directly.
