Rated 4.8 out of 5 by 279 reviewers.
Rated 5 out of 5 by High performance, quiet, efficient furnace The SLP98V is a highly efficient, quiet, high performance furnace. With a 98% efficiency rating for propane or natural gas is phenomenal. Converted from Oil heat to propane with a 18% increased efficiency rating not even factoring in the efficiency of the modulating system. Instaled a combination unit with heat pump and A/C for all season home comfort management. The dynamic thermostat monitor has multiple seasonal programs and times for personalized efficiency by home life. The thermostat even includes outside temperature, humidity and temperature settings. Highly recommend the combination units. November 16, 2012
Rated 5 out of 5 Very quite and lower operation cost After testing and running my new system and since then enjoying the very low noise from the system I found myself smiling. It's very quite and very efficient . July 15, 2014
Rated 5 out of 5 by Highly Recommended to me When spending lots of time researching a new furnace - I got in touch with a friend who lives further away and owns a heating/cooling company. He looked through all 5 proposals I had gotten from different companies. He suggested I get this specific furnace based on its efficiency and ability to maintain consistent temperatures with less energy. It is summertime now, so we have not truly had the chance to use our new furnace. However, the equipment, sales, install, and experience was a great one. I really appreciated knowing I was getting a top-of the line product, with a company that stands behind their products. July 12, 2014
Rated 5 out of 5 by Quiet, efficiency Very happy with the SLP98 furnace. Really like the way it slowly comes up to speed at the beginning of a cycle, and slowly reduces speed at the end. July 8, 2014

Rated 5 out of 5 by This product is top of the line. Very quiet, this product suites well my needs. That is the first time I got a modulated unit. June 27, 2014
Rated 4 out of 5 by Do not let the small size fool you Our new furnace is quiet, efficient and oh so small! I am amazed at the added space we now have in our furnace room and the efficiency we have gained for our home with our new furnace. Do not let it's small size fool you, it works just as well - if not better - than larger models! June 26, 2014

*This chart depicts potential energy savings you can expect from the SLP98V furnace, versus older furnaces with lower efficiency ratings. Criteria used in this example are 2,000 full-load heating hours, with a 60,000 Btuh heating design load and $1.368 ccf for gas. Your actual savings may vary, depending on the weather patterns in your local area, local fuel rates and your individual lifestyle.
