This page is the parent hub. Equipment depth — series ladders, capacity bands, and pairing notes — lives in the five child rooms. Start here if you know which part you need:

• Lennox air conditioners— cooling-only outdoor condensers (~49 in catalog)
• Lennox heat pumps— cooling plus heating in one outdoor box (~68)
• Lennox furnaces— gas heat for coil systems (~265)
• Lennox air handlers— indoor blowers for electric / hydro paths (~43)
• Lennox evaporator coils— coil-only matchups for outdoor + furnace or air-handler jobs (~102)

Pick the room that matches the part on your shortlist. If the job is a full system — outdoor plus indoor plus controls — shortlist the outdoor aisle first, then jump the indoor siblings. We will map the match before you buy.

Most residential shoppers meet three Lennox tiers in the filters:Merit seriesElite seriesand theSignature collection(Dave Lennox Signature).

• Meritis the value-oriented step — simpler staging and the models many replacement jobs start with.
• Eliteis the mid ladder — more staging and efficiency options on the SKUs we list in the child aisles.
• Signatureis the premium step — highest-tier families in the export.

ExactSEER2numbers for condensers and heat pumps live on the AC and heat-pump children. ExactAFUEand cabinet details for gas heat live on the furnaces child. Use this hub to choose the room; use the child aisle to compare SKUs.

HVAC USA carriesLennoxandTraneas equal brand menus — same five-room pattern for air conditioners, heat pumps, furnaces, air handlers, and evaporator coils.

Browse the peer brand hub:Trane equipment.

If you already know which brand your installer or design prefers, stay in that tree. If you are still choosing, climate, ductwork, and budget decide more than a slogan.

Beyond the five menu rooms, this parent catalog also includes other Lennox product types on the grid: Mini-Split (~59), Boiler (~27), Packaged Unit (~27), and Electric Heat Kit (~34).

Those SKUs stay on the parent catalog. We are not publishing dedicated child collection URLs for them in this menu setup. Need a heat kit, packaged unit, boiler, or mini-split match? We will pull the right family from the export when we confirm the job.

Shortlist on this grid, or open a child aisle and note the model families you like. Share tonnage, fuel type, climate notes, and what is already indoors.

We confirm sizing and indoor/outdoor matchups before you buy. You complete the purchase online once the SKUs are locked.

Freight and delivery expectations: see ourshipping policy.

Manufacturer coverage usually depends on how the equipment was sold, who installed it, and whether registration was completed on time. Internet-sold equipment can hit coverage limits that a brochure does not spell out on a collection page.

We keep that conversation honest before you buy when we confirm your SKUs. Confirm coverage before you assume a published warranty applies to a web cart SKU.

Plan the full ducted system:

• Outdoor air conditionerorheat pump
• Matched indoor path: furnace + evaporator coilorair handler
• Line set sized for the actual run
• Disconnect and whip
• Thermostat / controls
• Licensed startup and charge (EPA Section 608 — not a DIY refrigerant job)

Dual fuelpairs a heat pump with a compatible gas furnace and controls so the system can shift heat sources by outdoor conditions. That is a design call, not a filter checkbox. Use the child rooms above for each piece, then we lock the match before you buy.

In plain terms: Merit is the value residential tier, Elite is the mid step-up, and Signature is the premium Dave Lennox Signature Collection. Features, staging, and efficiency rise as you move up the ladder. Exact model families, SEER2, and AFUE live on the equipment children — openair conditionersheat pumpsorfurnacesfor depth.
