The SLP99V sits in Lennox's Dave Lennox Signature Collection. As of 2026-09-09 it is listed on Lennox's official site, which rates it up to 99% AFUE. It is a condensing furnace, so an installation uses plastic (PVC/CPVC) venting and needs a condensate drain.
The SLP99V delivers a modulating burner and uses an ECM variable-speed blower, as stated on Lennox's official product page (read 2026-09-09). Model-by-model capacities, cabinet sizes and clearances come from Lennox product data and installation literature, which this site adds to each record as it is verified; until then the rating plate remains the authority for the exact model.
BC Wide services SLP99V furnaces across Greater Vancouver: diagnosis and error-code reads, repairs, tune-ups and maintenance, and replacement with an equivalent current model. Technicians work from the full rating-plate model number, so family-level pages like this one are an entry point rather than a substitute for the model record.
