TEMPSTAR SmartComfort VS 80 Furnaces

Tempstar SmartComfort VS 80 Furnace Overview

Promoted by the manufacturer as a reliable and durable unit, the Tempstar SmartComfort VS 80 (or F8MV) is a variable speed, two-stage gas furnace achieving 80 percent AFUE. It can be installed in tight spaces thanks to its 33-inch height, is functional with many thermostats and is available in multi-position models. If the VS80 is installed in a downflow orientation, a downflow vent guard kit is required.

The VS 80 features an ECM variable speed motor that, according to the manufacturer, will save energy by operating more frequently at a low speed than the higher available speed. The unit’s variable-speed blower improves the quality of indoor air by removing moisture while cooling the home. Sound production is minimized by the solid steel, thermal-lined cabinet surrounding the blower. The heat exchanger is manufactured with corrosion-resistant aluminized steel and interlocking seams, making it durable against cracking or separating.

Equipped with a reliable direct hot surface ignition system and safety features that control the temperature limit, the VS 80 shuts off in the event of a system blockage. An electronic control system will communicate diagnostic information.

Tempstar SmartComfort VS 80 Furnace Reviews

"Tempstar is awesome"

5.0 rating
Very Satisfied

I would buy this brand again and recommend it to others. It is the furnace part of a Tempstar split unit air conditioner with gas furnace(model f8mv/v80 series). It is very quiet. It keeps our 2500 square foot home very comfortable. Our heating bills are about 20% less than with our old unit. The furnace filter is much easier to change than with our old furnace. Our prior Tempstar unit lasted from 1989 until 2010 with no repairs. We expect we will have the same reliability from this Tempstar furnace as well.

Other SmartComfort VS 80 Reviews

While little feedback is available online about the Tempstar SmartComfort VS 80, overall the unit seems to receive positive reviews. For example, one technician, advising a homeowner asking questions on www.hvac-talk.com about which furnace to install, states that “Tempstar is a nice AC.” This is in part due to a warranty that the tech considers top notch. The homeowner’s research leads him to prefer the Tempstar product over similar products from Carrier and Lennox.
