This collection is the Air Conditioners child underall Lennox equipment. Cooling-only outdoor units live here. When the job also needs heat or an indoor section, jump the sibling rooms instead of leaving the brand tree:

• Lennox heat pumps— cooling plus heating in one outdoor box
• Lennox furnaces— gas heat pairing for coil systems
• Lennox air handlers— indoor electric / hydro paths
• Lennox evaporator coils— coil-only matchups

Came in from the main Lennox nav? Stay on this aisle to shortlist condensers, then use the siblings when matchups call for them. Comparing aLennox air conditionerfor a replacement or a new install? Filter here first, then talk through load and matchups with us.

Lennox’s three residential tiers show up in the filters on this aisle. Start with series and BTU, then open the product page for the SEER2 on that exact SKU.

Merit seriesin this catalog includes ML13KC1 and ML14KC1 units titled as single-speed /single-stageplus ML17KC2 titled astwo-stage. These are the value-oriented outdoor options we list across common capacities.

Elite seriescovers EL15KC1 and EL16KC1 (single-stage titles) and EL18KCV / EL22KCV titled as variable-speed /variable-capacity. Step up here when you want finer staging and higher efficiency ceilings on the SKUs we show.

Signature collectionappears as the SL25KCV family in our export. Those four SKUs are UNLISTED on the storefront today — ask when you shortlist before you assume a web cart path.

How to filter this aisle

Filter by BTU and model family first. Open the product page for published SEER2 and the full title. If two SKUs look identical on paper, we confirm matchups before you buy.

Rated efficiency is a system number. Pair the outdoorcondenserwith a matchedair handlerorevaporator coil(and a furnace when that is your heat path). An unknown indoor section will not deliver the SEER2 on the brochure.

• Coil-only / furnace pairing:Lennox evaporator coilsandLennox furnaces
• Cooling plus heating in one outdoor box: compareLennox heat pumps

We confirm compatible indoor/outdoor combinations before you buy. AHRI pairs stay off this page until we verify them with you.

Lennox central aircondensers on this aisle run 18,000–60,000 BTU. That is a catalog fact, not a square-foot stamp. We are not publishing a sq ft chart here — those bands need owner approval and still are only a starting point before a Manual J.

SEER2on SKUs in this collection spans roughly 14.7 to 26. Higher SEER2 usually costs more up front; payback depends on climate, runtime, utility rates, and the indoor match.

We can help set a sane starting size before your installer runs the load calc.

Shortlist condensers with the filters, or note the tonnage you already know. We confirm sizing and indoor/outdoor matchups before you buy. You complete the purchase online once the SKUs are locked.

Plan on licensed startup and timely product registration. Equipment bought online without the proper authorized path can put coverage at risk. Ask what applies to the exact SKU when you shortlist — coverage depends on model, registration, and install path.

• Outdoor condenser from this aisle
• Matched evaporator coil or air handler (furnace too, if that is the heat path)
• Outdoor disconnect and electrical whip; breaker sized to the nameplate
• Licensed recovery, charge, and startup (not a DIY refrigerant job)

Large condensers usually move LTL freight to the curb; inspect before you sign. Shipping rules for the contiguous / lower 48 are on ourshipping policy. Alaska, Hawaii, and special freight need a custom quote.

In our catalog, Merit covers value ML13/ML14 single-stage and ML17 two-stage condensers. Elite adds EL15/EL16 single-stage plus EL18/EL22 variable-capacity models. Signature is the SL25KCV family — highest efficiency tier in the export, currently UNLISTED on the storefront. Ask for live availability before you plan around Signature.
