Lennox HS29 Air Conditioner Overview

The Lennox HS29 air conditioner, also known as the Elite 11, is a single-phase unit reaching up to 13.05 SEER with a 2.5- to 5-ton capacity, depending on the specific model. At the time of its manufacture, around 2005, this now-discontinued unit was Energy Star-qualified, had earned the Good Housekeeping Seal and its design, with few moving parts, reportedly increased the unit’s reliability compared to other units. The unit uses R-22 refrigerant.

The HS29 is manufactured with heavy-gauge galvanized steel and is coated with a baked-on finish, making it rust- and corrosion-resistant. A direct drive fan is precision-balanced to increase efficiency while keeping noise production as low as 74 decibels. Heat transfer is optimized by the highly efficient outdoor coil, which maintains low air resistance, and the unit is equipped with a Copeland scroll compressor for better air temperature control.

In order to protect the unit from damaging moisture, drainage holes are placed in the base pan. The condenser coil is protected from hail and debris by a non-corrosive PVC-coated steel wire guard, resulting in easier maintenance. Also, if the system needs to be accessed, the reusable service valves minimize refrigerant loss and allow easy recovery. The Elite HS29 has an improved dehumidification feature and optional add-ons such as an electric air cleaner.
