Features
Variable capacity, constant efficiency
This product offers variable-capacity operation, meaning it can adjust cooling output like a dimmer switch to perfectly match your energy use to your comfort needs. This also helps control humidity more accurately.
Use Less Energy. Save More Money
With efficiencies of up to 19.50 SEER2, the EL18KCV can deliver significant energy savings. In fact, it can help cut your energy bills and may even help you qualify for energy rebates.
A peacefully quiet environment
To reduce operating sound levels, the EL18KCV uses a sound-dampening system with a precision-balanced, direct-drive fan to ensure smooth, quiet operation. This lets it operate at a volume as quiet as 67 dB, or the sound of a clothes washer.
Your Digital Bridge into a World of Perfect Air
The efficient EL18KCV variable-capacity air conditioner is your digital bridge into a world of perfect air. When paired with a fully digital furnace or air handler and a Lennox S40 Smart Thermostat, it can step into a fully communicating home comfort system, maximizing its 19.50 SEER2 efficiency with modern communication features.
Cabinets designed for reliability
Cabinets built using superior materials and proprietary designs make Lennox units more attractive, durable and easier to install. Even maintenance is simplified thanks to the hinged design that allows quick access to the control panel and coils.
A refrigerant that’s better for the environment.
This product is compliant with 2025 EPA regulations for lower global warming potential (GWP) refrigerants. The Lennox choice of 2025 Compliant Refrigerant has a lower GWP than its predecessor and is formulated to provide excellent, reliable performance of your system for years to come.

You want the best? Get a Lennox!
March 13, 2026We had a new Lennox furnace, AC and zoning installed. The furnace is quiet & efficient, we don’t know it’s even there other than our warm cozy home. Too early to comment on the new AC and zoning but are excited to have a cool upstairs for sleeping in the hot days of summer.
Yes, I recommend this product.

Unit great don’t like thermostat at all.
March 12, 2026Furnace is great very quiet and does a good job. Still winterish so haven’t used ac yet. I hate the thermostat. I am used to a nest and yours is not responsive. I struggle to get temp turned down. Don’t have a clue how to turn off. I’ve tried countless times.
