EL18KCV — R-454B — 19.5 SEER2 — Variable capacity.

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.

I had Weiss Johnson come and remove two furnaces, redo a whole bunch of ducting, install a new high efficient furnace and also a heat pump. They went above and beyond with helping me. Relocated my hot water heater, moved and repaired a bunch of central vac lines and made everything look beautiful. Not to mention ran to my house at 9pm on a weekend to fix a small issue that could’ve waited. 10/10 from everyone involved.

had Reece and Nick from Weiss- Johnson come and install a new furnace. I have to say that I am extremely pleased with the job they did. They were very professional and pleasant to deal with. Reece is very knowledgeable and did a great job installing the new furnace answering all my questions. Nick did a great job installing the new ventilation pipes. If you are in need of a new furnace these are the guys to get.

First time using the services of Weiss-Johnson because our central ac was not starting. Celine was really nice to speak to and was very upfront about all the costs and services. Elie Haddad was our service person. Very impressed with how thorough and knowledgeable he is and quick diagnosis of the problem we were having with the AC. Will definitely hire Weiss-Johnson again for any AC and furnace related issues. Highly recommended.
