Lennox: US HVAC manufacturer known for the SLP99V variable-capacity furnace and the SL25XPV heat pump. Premium pricing, tightly-controlled dealer network.

Lennox International is one of the four largest residential HVAC OEMs. The Lennox SLP99V is the highest-AFUE residential furnace on the market (98.7% AFUE, fully variable capacity), and the SL25XPV is their cold-climate heat pump. Lennox sells through a tightly-controlled dealer network, which means parts availability is more dealer-dependent than other brands. Pricing tends to run 10-20% higher than equivalent Carrier or Trane equipment.
