Communicating Comfort

Tempstar® SmartComfort TXT+ Two-Stage Heat Pumps featuring the Observer™ communicating system are designed to take your home to a new level of comfort and efficiency. Teamed with our Observer communicating wall control and a Tempstar communicating fan coil or gas furnace, the TXT+ functions as part of a complete communicating home comfort system. Various components of the system “talk” to each other electronically, fine-tuning comfort levels while maximizing energy savings.


The TXT+ is built with premium components for quiet performance, including a two-stage scroll compressor with a deluxe sound blanket. A variable-speed fan motor operates primarily on quieter, lower speeds (HCH9 models only). Operating sound is further minimized by advanced aerodynamic fan and air discharge systems. This model typically runs at the lower stage, switching to higher operating levels as necessary. Custom-matched with a Tempstar variable-speed communicating fan coil or gas furnace, this two-stage operation delivers whisper-quiet operating sound levels and superior dehumidification. As part of a complete system, the TXT+ adjusts heating and cooling levels to match the needs of your home for a consistently comfortable flow of conditioned air.


Exceptionally durable steel cabinet with corrosion-resistant, appliance-grade paint. Filter drier removes moisture from the refrigerant and safeguards the long-term reliability of the refrigeration system.


  • Energy savings up to 19 SEER/10 HSPF could save up to 47% when compared to an older 10 SEER unit
  • Two-stage operation system reduces temperature and humidity swings in the home by heating and cooling evenly.

19 SEER/10 HSPF rating for HCA9 models when paired with select indoor equipment.
