Long life, straightforward operation
Thermo Products, marketed under the name of Thermo Pride, has been in business for around 60 years (since 1946), which is less than most of the major heating, ventilation and cooling companies. Consumer reviews of Thermo Pride furnaces seem to be very good, with few repairs being needed and good warranty coverage offered. Thermo Products claims to pride itself on making furnaces that are "built better to last longer." Indeed, Thermo Pride furnaces seem to have a reliably long life. On the other hand, the company doesn't offer many of the high-tech options that other manufacturers such as Trane and Carrier make available in their high-end furnaces.
Among the more interesting items in the Thermo Pride product offering are its oil furnaces. Although most of the major manufacturers offer oil furnaces with efficiencies only as high as 80 percent, Thermo Pride offers non-condensing, low-maintenance oil-fired units with efficiencies as high as almost 88 percent. Depending on your location and what kind of building you are installing the furnace in, that level of efficiency could make the difference between choosing a natural gas / propane appliance and an oil burner. Always check with your furnace installer for more information - pricing information on specific Thermo Pride units is not readily available. If Thermo Pride follows the average, it could cost you $3,000 to $5,000 (installed) for one of Thermo Pride's mid-efficiency furnaces.
Thermo Pride offers a limited lifetime warranty on the heat exchangers in all of its furnaces, and five years on all other parts. Better yet, this warranty is easily transferable to the next homeowner if you sell your home.
The bottom line is that Thermo Pride offers a durable, long-lived line of mid-efficiency furnaces and a few high-efficiency ones, but not the level of high-technology comfort options offered by some of the larger manufacturers. The warranty is easily transferable, so if you're considering selling your home in the next few years, a Thermo Pride furnace may be a better choice than a higher-efficiency (and more expensive) furnace from another manufacturer.
