Choosing the right furnace for your home can be more complicated than you might think. Since there are a variety of temperatures and weather conditions throughout the winter season in Minnesota, you have to make sure you have the heating system that fits your needs.

Marsh Heating and Air Conditioning is your dependable heating company in Fridley MN that offers an array of furnace models made by one of the best names in the industry: Lennox.

Here are a few things you need to give thought to before buying your next furnace:

Fuel Type

Furnaces are powered by different sources such as electricity, coal, fuel oil, and wood, but the most common source is natural gas. If you’re living in a region with extreme weather, a gas or oil powered model will provide the greatest comfort and efficiency.

Efficiency Rating

In addition to fuel type, you should also consider AFUE (Annual Fuel Utilization Efficiency) rating. Rule of thumb is, the higher the AFUE rating, the more savings you get. You should take note though that high-efficiency furnaces cost significantly higher than low and mid ones. The U.S. government requires all manufacturers and dealers to sell furnaces with a minimum of 80 percent AFUE.

Quality of Installation

Regardless of how expensive your brand new furnace may be, if it was installed incorrectly, you should expect problems sooner than later. Don’t discount your HVAC installer as an essential resource. A qualified technician will have relevant information about certain brands or models and their reputation in the industry. Also, choose a technician that is factory trained and certified to ensure a high-quality installation.

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 finding out what’s wrong with the system.
