TEMPSTAR SmartComfort VS 90 Furnace
Overview of SmartComfort VS 90
The Tempstar SmartComfort VS 90, also known as the T9MPV, is an Energy Star-rated variable speed, two-stage gas furnace with a 92-percent AFUE rating. It can be installed in tight quarters as an upflow, horizontal or downflow unit, although guard kits are required for downflow configurations. Compatible with several thermostats, the VS 90 is promoted by the manufacturer as an efficient and reliable furnace.
The VS 90's primary heat exchanger is an RPJIII model with rippled edges that are designed to increase efficiency by forcing more heat to the exterior surface. An ECM variable speed motor reduces energy consumption by frequently operating at a lower speed.
The variable speed circulation blower motor is surrounded by an insulated cabinet with a tight fit door latch system. It is pre-lubed and balanced to decrease sound production. Additionally, the blower motor dehumidifies the air when the furnace is in cooling mode and improves indoor air quality.
The VS 90's direct hot surface ignition system employs in-shot burners and an advanced silicon nitride igniter. The unit's diagnostic capabilities aid with repairs, and safety features protect the home and unit by shutting down the furnace if a significant problem, such as a system blockage, arises.
