The ESP-V Series vertical cooling/heat pump units feature a space-saving design suitable for condos and homes built on a slab, with no basement or attic, says the manufacturer. Available in capacities ranging from 2 to 5 tons, the ESP-V features a larger coil for higher efficiency, an aluminum corrosion-resistant drain pan, and a compact, internal control box, says the company. The motor includes an optional filter box kit that can be attached directly to the unit, allowing return air to be drawn through a louvered door or through the wall when space limitations do not allow for a standard, through-the-wall grille.
