Lennox EL18KCV Variable-Capacity Air Conditioner Installation in Calgary

Complete Lennox variable-capacity central air conditioner installation from $7,495 + GST.

Experience quieter, more precise cooling with the Lennox EL18KCV—one of Lennox’s newest high-efficiency central air conditioners.

The EL18KCV uses variable-capacity compressor technology to automatically adjust its cooling output based on the needs of your Calgary home. Instead of repeatedly turning on and off at full capacity, it can operate at lower output for longer periods, helping maintain consistent temperatures while reducing noise and energy consumption.

Revolve Supplies provides professional Lennox EL18KCV installation throughout Calgary and surrounding communities. Financing is available, and next-day installation may be offered depending on equipment and crew availability.

• Improved humidity management
• Reduced system cycling
• Better comfort throughout the home

Lennox S40 Communicating Controls

The EL18KCV can operate with compatible conventional HVAC controls. For complete Lennox communicating operation, it can be paired with:

A fully communicating system can provide more coordinated airflow, advanced diagnostics, system alerts and remote-control features.

Frequently Asked Questions

How much does a Lennox EL18KCV cost in Calgary?

A complete Lennox EL18KCV installation starts from  $7,495 + GST. A standard 3-ton package is $8,895 + GST.

Final pricing depends on equipment size, indoor-coil requirements, refrigerant-line length, electrical work, thermostat selection and installation conditions.

Is the EL18KCV Lennox’s newest EL18 air conditioner?

Yes. The EL18KCV is the newer R-454B replacement for the previous EL18XCV R-410A air conditioner.

Is the EL18KCV a variable-capacity air conditioner?

Yes. Its variable-capacity compressor can adjust cooling output instead of operating at only one or two fixed cooling stages.

Does the EL18KCV require a Lennox S40 thermostat?

Not necessarily. The system can operate with compatible conventional controls. However, the S40 and a compatible Lennox indoor unit are required to create a fully communicating Lennox system.

The Lennox EL18KCV provides efficiency ratings of up to 19.5 SEER2, depending on the indoor equipment and approved system combination.

What size does my Calgary home require?

The EL18KCV is available in 2, 3, 4 and 5-ton capacities. The correct size depends on the home’s cooling load and existing HVAC system—not square footage alone.

Does it include a 10-year warranty?

The compressor includes a 10-year limited warranty. Qualifying residential installations can receive 10-year extended limited coverage on eligible components when the system is registered within Lennox’s required period.

Is financing available?

Yes. Financing is available at 9.99% for up to 10 years, subject to credit approval and applicable terms.
