The 15 and 20 ton Rheem 3 phase RKKL Package Gas/Electric units feature earth-friendly R-410A refrigerant. All of our residential/commercial package units, regardless of efficiency level, feature the Scroll® Compressor. The scroll compressor uses a more advanced technology than traditional reciprocating compressors.  They have fewer moving parts, and they are quieter, more efficient, and longer lasting.Foil faced insulation encapsulated throughout entire unit minimizes airborne fibers from the air stream. Slide Out Indoor fan assembly for added service convenience. Hinged major access door with heavy-duty gasketing. Our motor mount helps protect the fan motor from the elements for longer life. High performance belt drive motor with variable pitch pulleys and quick adjust belt system. Control box operational controls are “up front” for quick access and service diagnostics.  The draft inducer motor is specially designed to quietly provide combustion air while simultaneously venting outdoors the combustion products from the furnace heat exchanger.

In addition to the draft inducer motor, the in-shot gas burners, gas valve and manifold efficiently regulate the flow of gas for combustion.  These new gas/electric units also feature direct-spark ignition and remote flame sensors for added dependability and efficiency The blower is responsible for the flow of air into your ductwork. Aluminum MicroChannel Outdoor Coils and other system components provide maximum efficiency and quiet operation. Single slab, single pass designed evaporator coil facilitate easy cleaning for maintained high efficiencies. ac window unit angleInternally sloped slide out condensate pan conforms to ASHRAE 62 standards.ac unit falls out window Our new package gas electric units feature a tubular heat exchanger design. 12 ton hvac unit cost

Tubular heat exchangers are more efficient and durable than older-style clamshell heat exchangers. RKKL (15 & 20 Ton) Conditional Parts Warranty - 10 Years (1-Phase Residential - Registration Required), 1 Year (Commercial) Lennox introduces high-efficiency Energence® rooftop units in 20- to 30-ton models Dallas, TX – (February 21, 2012) – Lennox Industries is proud to introduce the new high-efficiency Energence® 20- to 30-ton rooftop units. These new models will replace Lennox’ L Series® 21- to 30-ton rooftop units seamlessly, without requiring curb or utility connection modifications. The new Energence rooftop units offer higher efficiency levels above their L Series predecessors, with up to an 8% improvement in EER and a 10% improvement in IEER efficiency ratings. They are available in 20-ton gas/electric and electric/electric variable air volume (VAV) models, as well as 25-ton and 30-ton gas/electric and electric/electric constant air volume (CAV) and VAV models.

Most new models exceed the Consortium of Energy Efficiency (CEE) Tier 2 standards. Additional features of the new 20- to 30-ton Energence units include: The Prodigy® Unit Controller, standard on every unit, makes setup, troubleshooting and servicing easier than ever through intelligent operation and verification, tracking the runtime of every major system component and recording the date and time when service or maintenance is performed. A built-in SmartWire™ System that simplifies installation through advanced keyed and color-coded connectors, helping to prevent miswiring and increasing jobsite efficiency. Lennox’ new Environ™ Condenser Coil System that uses over 38% less refrigerant, has a compact design, fewer brazed joints and comes with a standard 3-year warranty. Foil-faced insulation on all internal surfaces that contact airflow, helping to minimize airborne fibers and improve IAQ. Blower belt auto-tensioner that provides proper tension without the need for regular adjustments and maintains airflow and proper performance.
