Stealth 3 Ton 18 SEER Ducted Central Air Inverter Heat Pump Split System | Max Heat - SC-2436-HP / SC-36-AH
Stealth Central Heat and Air Systems featuring Max Heat unite the remarkable efficiency of an inverter condenser with a cutting-edge air handler seamlessly integrated into your current ductwork infrastructure.
2-3 Ton 20 SEER Stealth Central Heat & Air Inverter Condenser | Max Heat

The Stealth central ducted condensers' integrated inverter compressor ensures maximum efficiency by adjusting system BTU output and fan speed to precisely match demand. This functionality happens in both heating and cooling modes. Max Heat technology extends the heat pump operating range down to -22°F outside temperature. With up to a 17 SEER2 rating, these Stealth central ducted condensers give you better performance and more features than any other brand.
Features
-
Max Heat Technology: Max Heat Technology is extended heat pump performance. A secondary benefit of a self-adjusting compressor is the ability to speed or slow refrigerant and air flow at the outside unit - maximizing heat extraction. Older, traditional heat pumps stop working below 30°F, but the Stealth Heat Pump Condenser keeps you comfortable in any weather.
-
Flexibility: These Stealth condensers are designed with your ultimate comfort in mind. Experience unparalleled flexibility as these innovative condensers can be easily configured to operate at both 24k and 36k capacities, seamlessly adapting to your specific requirements when coupled with the corresponding air handlers. Your comfort, your choice.
-
Durability and Reliability: Rugged construction and an acrylic resin gold fin coating on the outside condenser coil adds up to a long, trouble-free service life. The inside evaporator has blue fin coating protection and a sturdy 8-speed fan. Precision engineering is behind every Stealth central ducted model, resulting in powerful performance across a punishing range of conditions.
-
Quiet Comfort: Every Stealth central ducted condenser has a slim, horizontal discharge design, ideal for close lot-line installations. Outside noise level is no more than 55 dBa max, equivalent to a dishwasher. The indoor unit fan has 8 speeds, for near-silent operation. Give your home complete comfort at maximum efficiency with a Stealth central ducted heat pump system.
-
14-Year Warranty: The Stealth central ducted condensers features a 14-year compressor/5-year parts warranty with online registration. Without registering the warranty, you are still protected by the standard 7-year compressor/5-year parts warranty.
