The Lennox SL280V is a variable-speed gas furnace with a heating efficiency of 80% AFUE. The variable-speed motor operates mostly on low on mild days, resulting in energy savings and more consistent temperatures. The variable-speed technology is also designed to deliver greater humidity control. A sealed blower compartment increases efficiency and combines with sound-absorbing materials to provide quiet operation. A steel Duralok heat exchanger and silicone nitride SureLight igniter are designed for durability and long life. The SL280V can be paired with a matching Lennox air conditioner or heat pump to improve the system’s SEER. The SL280V is part of the Dave Lennox Signature Collection.
We installed a new Lennox four years ago and now the Blower is not coming up. Lennox is like monopoly where they have only a few service dealers so they control the cost of the parts and repair high. I had a very good HVAC company come to fix it but the error code they got doesn’t even show on the furnace panel and Lennox technical support did not get back to them so I am trying to find this authorized dealer from Lennox Mafia that may get an answer from Lennox. Do not buy this junk Lennox, there are so many better, Trane or Bryant.

"Keeping The Garage Warm"
5.0 rating
Very Satisfied
I love this thing. Our partnership began a few weeks ago when I picked him up from a garage sale to prepare for winter. I just moved to Colorado, and I didn’t want to be cold this winter or be forced to pay for electricity to heat a poorly insulated garage. At first, when I turned it on, I wasn’t sure it was working- it was that quiet! It was a little slow to start, but gradually it heated my garage to a tolerable temperature. I think it has a speed knob for the fan, but I couldn’t tell. I was happy with how well it worked. I would definitely recommend this brand, and even this specific model, to my friends. The Lennox brand and the engineers responsible for making this appear to know what they are doing. This thing could probably heat my entire house. I would definitely buy this again, even new. Great quality.

"Wish I could have a test drive before purchase"
2.0 rating
Somewhat Unsatisfied
Warning. We just purchased the model named and find it very noisy. After two visits from the dealer, we cannot make the whining noise go away, especially in the second half of the run. We are unsatisfied with the purchase and wish we could have heard the system before we paid for it. Hopefully, the Lennox dealer will give us the full refund if not 100% satisfied, as stated in their furnace performance guarantees.

We purchased Lennox sl280v furnace to replace aging Goodman Manufacturing equipment. We have compared brands and tried to find the best deal for the bucks. Lennox produces the best equipment on the market.
Most questions about the SL280V on HVAC forums are about thermostat and wiring set-up issues. A consumer on hvac-talk.com had a problem with the fan hitting the housing gasket as it rotated on his new unit, which the installer repaired.
