All About the Lennox EL180E Gas Furnace

Posted: 2020-03-17

A malfunctioning furnace can cause major discomfort to you and your family. That’s something you wouldn’t want to deal with even when winter is about to end. If you have an aging, inefficient furnace, you’re probably wasting a lot of money on fuel and repair costs. When a furnace is nearing the end of its life, it usually has to work harder to provide the heating needs of your home.

Four Seasons Air Specialists is your leading heating company in Circle Pines MN that can help you diagnose your existing furnace and determine whether it’s due for a replacement.

Things to Consider When Buying a New Furnace


Not all furnaces are engineered the same, including their power sources. One of the first things to consider when buying a new furnace is the source of power that will run the system. For the most part, furnaces can be powered by natural gas, oil, or electricity.

Gas furnaces are the most popular and are typically more budget-friendly than the other two. But keep in mind that they also tend to need more maintenance than oil or electric furnaces.

Proper Sizing

Buying the most expensive furnace doesn’t necessarily mean you’re buying the right furnace. When it comes to heating systems, size does matter, particularly proper sizing.

Generally, an undersized furnace lacks the heating power and costs more to operate. On the other hand, an oversized furnace is too powerful for your home and heats the home too quickly and consumes too much energy.

Having the right-sized furnace installed in your home guarantees the right balance between energy efficiency and comfort.

Energy Efficiency

If your existing furnace has an AFUE (annual fuel utilization efficiency) rating of lessou than 80 percent, it no longer complies with the government’s standards. Since your furnace is going to be one of the major energy consumers in your home, you should look for a furnace that is efficient enough to help you minimize your heating costs.

Features of the Lennox EL180E Gas Furnace

The EL180E has an efficiency rating of up to 80 percent AFUE, which can save you hundreds of dollars in heating costs per year, compared to older, low-efficiency furnaces.

When compared to a standard single-speed motor, the Power Saver motor delivers significant energy savings, without sacrificing comfort. Its constant torque motor adjusts airspeed based on demand, helping the furnace use less energy in heating and cooling modes. The EL180E is 33 percent more efficient than standard motors. When working with an air conditioner or a heat pump as part of a complete Lennox home comfort system, it can increase overall cooling efficiency by one or more SEER points. That translates to more savings on energy after the last snowfall.

Its Power Saver™ motor operates at constant torque to help maintain consistent airflow. This technology not only provides energy boost capabilities improving the overall system efficiency, similar to a variable speed furnace but also delivers higher SEER ratings in cooling mode. In continuous fan mode, this technology helps keep energy waste to a minimum.

The consistent flow of air helps keep temperatures inside your home comfortable, even as the weather outside is changing. And because it’s continually rotating, the Power Saver motor delivers quiet heating performance, removing the noisy startup sounds associated with single-stage motors.

Every component of the EL180E has proven itself through extensive testing in our research labs. So you can take comfort knowing the furnace will deliver reliable performance, season after season.

To minimize heat loss and maximize comfort and efficiency, Lennox created an insulated blower compartment for this model.

For your peace of mind, the EL180E comes with a 20-year limited warranty on the heat exchanger and a 10-year limited warranty on all remaining covered components.

The EL180E has a Duralok Plus heat exchanger that is constructed from patented ArmorTuf steel that captures waste heat, and a stainless steel secondary heat exchanger that allows the unit to achieve industry-leading efficiency levels. This solid component exceeds industry requirements and extends the furnace’s life.

The EL180E includes special sound-absorbing materials that further reduce sound for even quieter operation.

To further lessen heat loss, Lennox designed the EL180E with an elegantly-styled, durable steel cabinet with high-quality paint finish.

Its top vent with rotatable inducer simplifies horizontal installations.

Its Surelight Igniter’s nitride design provides long product life and reliable operation.

The EL180E’s Surelight Integrated Furnace Control manages furnace operation and provides direct readout diagnostics for quick troubleshooting. That means your technician won’t take that much time to find out what’s wrong with the system.
