Lennox

Start with the type of equipment you need. Each page below lets you compare Lennox models by size and efficiency.

• Lennox air conditioners (cooling-only outdoor units)
• Lennox heat pumps (cooling and heating in one outdoor unit)
• Lennox furnaces (gas heat, paired with an evaporator coil)
• Lennox air handlers (indoor blower units for heat pump and AC systems)
• Lennox evaporator coils (indoor coils that sit on a gas furnace)

Replacing a full system? Pick the outdoor unit first, then the matching indoor equipment. We confirm the match with you before you buy.

Lennox sorts its home equipment into three tiers: the Merit series, the Elite series, and the Dave Lennox Signature Collection.

Merit is the value tier, with simpler staging. Many replacement jobs start here.

Elite is the step-up tier, with more staging and higher efficiency, including variable-capacity air conditioners and variable-speed heat pumps.

Signature is the premium tier. You can order Signature furnaces (the SL280 and SL297) online. Call us about Signature air conditioners and heat pumps.

Compare exact SEER2 ratings on the air conditioner and heat pump pages, and AFUE and cabinet widths on the furnace page.

HVAC USA carries both Lennox and Trane, with air conditioners, heat pumps, furnaces, air handlers, and evaporator coils from each brand.

To compare the other brand, see Trane equipment.

If your contractor already works with one brand, start there, because the contractor’s certification is what keeps your full warranty in place. If you’re still choosing, your climate, ductwork, and budget matter more than the badge.

You'll also find Lennox electric heat kits here (the ECB45, ECB47, and ECBA25) for Lennox air handlers. Looking for a Lennox product you don't see? Call or text (913) 364-0070 and we'll check availability with you.

Shortlist the models you like here or on each equipment page. Then share the size, fuel type, climate, and what’s already in your home.

We confirm sizing and the indoor and outdoor match before you buy. You complete the purchase online once the equipment is right.

HVAC USA is an authorized Lennox reseller, and everything we sell is new factory equipment. Your full Lennox warranty applies when a licensed, manufacturer-certified contractor installs your system and registers it within 60 days.

Ask what applies to your exact model when you call.

Plan the full ducted system:

• Outdoor unit: an air conditioner or a heat pump
• Indoor side: a furnace with an evaporator coil, or an air handler
• Line set sized for the actual run
• Outdoor disconnect and electrical whip
• Thermostat and controls
• Licensed startup and refrigerant charge (EPA Section 608 work, not a DIY job)

Dual fuel pairs a heat pump with a compatible gas furnace and controls, so the system can switch heat sources as the outdoor temperature changes. That’s a design decision, so we confirm the match with you before you buy.

Merit is the value tier, Elite is the step-up tier, and Signature is the premium Dave Lennox Signature Collection. Staging, features, and efficiency rise as you move up. Compare exact models, SEER2, and AFUE on the air conditioner, heat pump, and furnace pages.

Cooling only: Lennox air conditioners. Heating and cooling from one outdoor unit: Lennox heat pumps. Gas heat: Lennox gas furnaces. An indoor blower for a heat pump or AC: Lennox air handlers. A coil for your furnace: Lennox evaporator coils. No ducts: Lennox mini-splits.
