Overview of the SL280V
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.

"Keeping The Garage Warm"
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"
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.

"Loud motor affects the air condition unit"
We purchased Dave lennox sl280v furnace six weeks ago to go with the Lennox 13acx air condition that we bought last summer.We did not know that the blower motor -which is part of the new furnace -will be the blower motor for my air condition as well. Our new ac used to be very quiet until the furnace got installed. Now my ac is incredibly loud because it is utilizing the furnace motor to blow the air. It is a nightmare! The ac is so very loud, with a straining surging noise, but the furnace is running quietly. When we installed the ac last year it was very quiet because it was using the blower motor of my old furnace. We bought new Lennox products because we were pleased with our previous old furnace and ac The new Lennox models are not quiet as the ones we had before for 16 years . We still do not know how we are going to deal with this problem.
